  • RESTful principles question

    - by auser
    An intelligent coworker friend of mine brought up a question to me that I was uncertain how to answer and I'd like to pose it to the world. If a RESTful endpoint uses token-based authentication, aka a time-based token is required to access a resource and that token expires after a certain amount of time, would this violate the RESTful principle? In other words, if the same URL expires after a certain amount of time, so the resource returns a different response depending when it was requested, is that breaking REST?

  • What RESTful API would you use for a turn-based game server?

    - by Ross
    How would you model a turn-based game server as a RESTful API? For example, a chess server, where you could play a game of chess against another client of the same API. You would need some way of requesting and negotiating a game with the other client, and some way of playing the individual moves of the game. Is this a good candidate for a REST (RESTful) API? Or should this be modelled a different way?

  • flickr.photos.search strange behavior with nested xml response

What amI missing - How is this possible in light of the fact that the response string is definitely formed as I would expect it to be?

  • Passing JSON through the URI

    - by Leaf
    I'm trying to create a REST based web service with data encapsulated using JSON. My problem is when I pass the string version of JSON in the URI it turns to something like this: %7B%22coal%22:100,%22ele%22:1500.1%7D. I'm wondering if there are any functions Java for converting between the escaped and unescaped versions so I can parse the string.

  • Unable to fetch Json data from remote url

    - by user3772611
    I am cracking my head to solve this thing. I am unable to fetch the JSON data from remote REST API. I need to fetch the JSOn data nd display the "html_url" field from the JSON data on my website. I saw that you need the below charset and content type for fetching JSON. <html> <head> <meta charset="utf-8"> <meta http-equiv="content-type" content="application/json"> </head> <body> <p>My Instruments page</p> <ul></ul> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script type="text/javascript"> $(document).ready(function () { alert("Inside the script"); $.getJSON(" https://pki.zendesk.com/api/v2/help_center/sections/200268985/articles.json", function (obj) { alert("Inside the getJSON"); $.each(obj, function (key, value) { $("ul").append("<li>" + value.html_url + "</li>"); }); }); }); </script> </body> </html> I referred to following example on jsfiddle http://jsfiddle.net/2xTjf/29/ The "http://date.jsontest.com" given in this example also doesn't work in my code. The first alert is pops but not the other one. I am a novice at JSON/ Jquery. i used jsonlint.com to find if it has valid JSON, it came out valid. I tested using chrome REST client too. What am I missing here ? Help me please ! Thanks in anticipation.

  • How to add multiple cookies to Response in WCF / REST service

    - by Sumtraveller
    I have access to WebOperationContext and can add one cookie by doing this: WebOperationContext.Current.OutgoingResponse.Headers.Add("Set-Cookie: foo_a=bar_a"); However if I call that several times, e.g.: WebOperationContext.Current.OutgoingResponse.Headers.Add("Set-Cookie: foo_a=bar_a"); WebOperationContext.Current.OutgoingResponse.Headers.Add("Set-Cookie: foo_b=bar_b"); I should get the following in my header (2 cookies): Set-Cookie: foo_a=bar_a Set-Cookie: foo_b=bar_b But instead get: Set-Cookie: foo_a=bar_a, foo_b=bar_b How do I set multiple cookies? Thx

  • ntpd on Fedora Core 6 with high negative time rest values

    - by Mark White
    The basic problem is we have a FC6 server instance running on a virtual machine, and the system time seems to have been slowly varying until it is now causing a problem. The server runs 24/7 and has been up for 155 days. It has been changed to show GMT, and reports the time as (example) 00:15:15 GMT whereas the actual time is 00:00:00 GMT. This is an offset of 915 seconds. selinux has been changed to 'setenforce 0' for testing and I am running as root. I stop the ntpd service and change the time in System|Administration|Date & Time. The time still shows the same with 'date' in bash. There are no error logs. I change the date with 'date --set' in bash. The response confirms the changed date. I run 'date' and the incorrect date is shown. There are no error logs. I start the ntpd service and /var/log/messages shows success with 'time reset -915.720139s'. The date remains unchanged. ntpq -p shows three three time servers all have offsets of around -915 seconds. I stop ntpd service and try 'ntpd -gqx' and get the same result as above - success, but a large negative time reset. I've tried varying combinations of the above, and a few more settings in System|Administration|Date & Time - no change. I just need to reset the system time to GMT. No offset. But I can't wait for ntpd to slew the time over the next few weeks. Any advice is welcome, cheers! Sure this shouldn't be this difficult... Mark...

  • User signup in REST API

    - by Bhaktavatsalam Nallanthighal
    I have a PHP web application that I want to make accessible across multiple clients. So, I'm trying to make it more like an API. My question is: How would I handle the creation of new users using the API? If I have a URL like http://example.com/user/signup which takes new user details and creates a new user via a POST request, wouldn't it be a problem that people can misuse it and create fake users easily?

  • Upload a Photo to Facebook with REST API and Ruby

    - by Michael Waxman
    It's much harder than you'd think: http://wiki.developers.facebook.com/index.php/Photos.upload The tricky part is how to create the MIME multi-part message in Rails, which Facebook requires. I'm also using a Ruby Facebook API gem (mini_fb) which signs my other requests, and in addition to having no idea how to set up the MIME multi-part, even if I did I'm not sure how to add in the required signature values with the gem. Please help!

  • How to bind "rest" variables to list of values in macro in Scheme

    - by Slartibartfast
    I want to make a helper macro for writing match-extensions. I have something like this: (define-match-expander my-expander (? (stx) (let* ([dat (cdr (syntax-e stx))] [var1 (car dat))] [var2 (cadr dat)]) ;transformer goes here ))) So I wanted a macro that will do this let binding. I've started with something like this: (define-syntax-rule (define-my-expander (id vars ...) body) (define-match-expander id (? (stx) (match-let ([(vars ...) (cdr (syntax-e stx))]) body)))) but match-let isn't defined in transformation time. First question would be is there any other way of doing this (making this expanders, I mean)? Maybe there is already something similar in plt-scheme that I'm not aware of, or I'm doing it wrong in some way. Regardless of answer on the first question, if I ever want to bound list of variables to list of values inside of a macro, how should I do it? EDIT: In combination with Eli's answer macro now looks like this: (define-syntax-rule (define-my-expander (id vars ...) body) (define-match-expander id (? (stx) (syntax-case stx () [(_ vars ...) body]))))

  • CABasicAnimation not scrolling with rest of View

    - by morgman
    All, I'm working on reproducing the pulsing Blue circle effect that the map uses to show your own location... I layered a UIView over a MKMapView. The UIView contains the pulsing animation. I ended up using the following code gleaned from numerous answers here on stackoverflow: CABasicAnimation* pulseAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"]; pulseAnimation.toValue = [NSNumber numberWithFloat: 0.0]; pulseAnimation.duration = 1.0; pulseAnimation.repeatCount = HUGE_VALF; pulseAnimation.autoreverses = YES; pulseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:pulseAnimation forKey:@"pulseAnimation"]; CABasicAnimation* resizeAnimation = [CABasicAnimation animationWithKeyPath:@"bounds.size"]; resizeAnimation.toValue = [NSValue valueWithCGSize:CGSizeMake(0.0f, 0.0f)]; resizeAnimation.fillMode = kCAFillModeBoth; resizeAnimation.duration = 1.0; resizeAnimation.repeatCount = HUGE_VALF; resizeAnimation.autoreverses = YES; resizeAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:resizeAnimation forKey:@"resizeAnimation"]; This does an acceptable job of pulsing/fading a circle I drew in the UIView using: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(context, 1.0, 0.0, 0.0, 0.4); // And draw with a blue fill color CGContextSetRGBFillColor(context, 1.0, 0.0, 0.0, 0.1); // Draw them with a 2.0 stroke width so they are a bit more visible. CGContextSetLineWidth(context, 2.0); CGContextAddEllipseInRect(context, CGRectMake(x-30, y-30, 60.0, 60.0)); CGContextDrawPath(context, kCGPathFillStroke); But I soon found that while this appears to work, as soon as I drag the underlying map to another position the animation screws up... While the position I want highlighted is centered on the screen the animation works ok, once I've dragged the position so it's no longer centered the animation now pulses starting at the center of the screen scaling up to center on the position dragged off center, and back again... A humorous and cool effect, but not what I was looking for. I realize I may have been lucky on several fronts. I'm not sure what I misunderstood. I think the animation is scaling the entire layer which just happens to have my circle drawn in the middle of it. So it works when centered but not when off center. I tried the following gleaned from one of the questions suggested by stackoverflow when I started this question: CABasicAnimation* translateAnimation = [CABasicAnimation animationWithKeyPath:@"position"]; translateAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(oldx, oldy )]; translateAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(x, y )]; // translateAnimation.fillMode = kCAFillModeBoth; translateAnimation.duration = 1.0; translateAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; [self.layer addAnimation:translateAnimation forKey:@"translateAnimation"]; But it doesn't help much, when I play with it sometimes it looks like once time it animates in the correct spot after I've moved it offcenter, but then it switches back to the animating from the center point to the new location. Sooo, any suggestions or do I need to provide additional information.

  • REST API for driving distance?

    - by Mark
    Is there a service that will give me the driving distance between two addresses? Apparently Google Maps API requires you to display a map, which I don't want to do (on that particular page), and I'd like to just snag the data and save it to my DB after a user submits a form, rather than waiting for JS to do it's thing. If it's relevant, this is going into a Django app. I discovered that CloudMade offers a Python API, which is nice, except their latest dev release has a bug in it (can't use the API object), but more importantly, it's support for Canada is awful/worthless (couldn't find directions from any major city around here!).

  • Delete ONE SPECIFIC table of a database - leave the rest intact

    - by Jayomat
    Hi, I have a database where I store two different kinds of data. One table is for favorite routes, the other stores the retrieved routes from a server. I can retrieve the routes etc just fine. But after retrieving the first Route, pressing back or HOME, and then retrieving another route, the routes table is filled with all the old routes plus the new ones. So my question: how do I delete ONLY the routes table and not the whole database because I don't want to delete the added favorites....?! I found the following function in the android docs: public int delete (String table, String whereClause, String[] whereArgs) and I tried to implement it, but I must pass a SQLiteDataBase as an argument. But how? I implemented: public void deleteTableRoutes(SQLiteDataBase db){ db.delete("routes", null, null); } But I want to call this function from a different class where I have no reference to the database.. so what do I have to pass as an argument? Or how do I get a reference to my database? I build my database upon the code example of the NotePadExample from the dev docs. How to solve this problem? thanks

  • How to create 2 different scripts for 2 browsers (IE+all the rest)

    - by Barnabas Nagy
    I'm trying to solve an IE CSS issue by using conditional tags. My jQuery that does the job of tabbed box effect calls an id that is inside the conditional tags. I've given new ids to IE so on IE the jQuery is not working. I tried to duplicate the script with the new id in one of the script but the 2 scripts seems to get in conflict. My jQuery (in between the head tags) is (for all all browsers except IE): <script> var currentTab = 0; // Set to a different number to start on a different tab. function openTab(clickedTab) { var thisTab = $(".tabbed-box .tabs a").index(clickedTab); $(".tabbed-box .tabs li a").removeClass("active"); $(".tabbed-box .tabs li a:eq("+thisTab+")").addClass("active"); $(".tabbed-box .tabbed-content").hide(); $(".tabbed-box .tabbed-content:eq("+thisTab+")").show(); currentTab = thisTab; } $(document).ready(function() { $(".tabs li:eq(0) a").css("border-left", "none"); $(".tabbed-box .tabs li a").click(function() { openTab($(this)); return false; }); $(".tabbed-box .tabs li a:eq("+currentTab+")").click() }); </script> And I would need this for IE: <script> var currentTab = 0; // Set to a different number to start on a different tab. function openTab(clickedTab) { var thisTab = $(".tabbed-box .tabs a").index(clickedTab); $(".tabbed-box ie-.tabs li a").removeClass("active"); $(".tabbed-box ie-.tabs li a:eq("+thisTab+")").addClass("active"); $(".tabbed-box .tabbed-content").hide(); $(".tabbed-box .tabbed-content:eq("+thisTab+")").show(); currentTab = thisTab; } $(document).ready(function() { $(".ie-tabs li:eq(0) a").css("border-left", "none"); $(".tabbed-box .ie-tabs li a").click(function() { openTab($(this)); return false; }); $(".tabbed-box .ie-tabs li a:eq("+currentTab+")").click() }); </script> Having the 2 scripts in the head conflicts with each other. Maybe there is a way to combine them?

  • Neo4j 1.9.4 (REST Server,CYPHER) performance issue

    - by user2968943
    I have Neo4j 1.9.4 installed on 24 core 24Gb ram (centos) machine and for most queries CPU usage spikes goes to 200% with only few concurrent requests. Domain: some sort of social application where few types of nodes(profiles) with 3-30 text/array properties and 36 relationship types with at least 3 properties. Most of nodes currently has ~300-500 relationships. Current data set footprint(from console): LogicalLogSize=4294907 (32MB) ArrayStoreSize=1675520 (12MB) NodeStoreSize=1342170 (10MB) PropertyStoreSize=1739548 (13MB) RelationshipStoreSize=6395202 (48MB) StringStoreSize=1478400 (11MB) which is IMHO really small. most queries looks like this one(with more or less WITH .. MATCH .. statements and few queries with variable length relations but the often fast): START targetUser=node({id}), currentUser=node({current}) MATCH targetUser-[contact:InContactsRelation]->n, n-[:InLocationRelation]->l, n-[:InCategoryRelation]->c WITH currentUser, targetUser,n, l,c, contact.fav is not null as inFavorites MATCH n<-[followers?:InContactsRelation]-() WITH currentUser, targetUser,n, l,c,inFavorites, COUNT(followers) as numFollowers RETURN id(n) as id, n.name? as name, n.title? as title, n._class as _class, n.avatar? as avatar, n.avatar_type? as avatar_type, l.name as location__name, c.name as category__name, true as isInContacts, inFavorites as isInFavorites, numFollowers it runs in ~1s-3s(for first run) and ~1s-70ms (for consecutive and it depends on query) and there is about 5-10 queries runs for each impression. Another interesting behavior is when i try run query from console(neo4j) on my local machine many consecutive times(just press ctrl+enter for few seconds) it has almost constant execution time but when i do it on server it goes slower exponentially and i guess it somehow related with my problem. Problem: So my problem is that neo4j is very CPU greedy(for 24 core machine its may be not an issue but its obviously overkill for small project). First time i used AWS EC2 m1.large instance but over all performance was bad, during testing, CPU always was over 100%. Some relevant parts of configuration: neostore.nodestore.db.mapped_memory=1280M wrapper.java.maxmemory=8192 note: I already tried configuration where all memory related parameters where HIGH and it didn't worked(no change at all). Question: Where to digg? configuration? scheme? queries? what i'm doing wrong? if need more info(logs, configs) just ask ;)

  • IE6 SELECT HTML tag causes rest of page to vanish

    - by Jonas Byström
    The following HTML does not work in IE6 for me: <html><body>This text is visible.<textarea>This too.</textarea> This is not visible. <select><option value="a">A</option><option value="b">B</option></select> Neither is this. <textarea>Nor this.</textarea> Nor this. </body></html> In IE6, every time I put a select drop-down in the code, everything thereafter dissappears (and some before too, as you can see). All texts are visible in both IE8 and Firefox. Is this a known bug on IE6? Could it have something to do with Windows 7? Or could it be my installation of Internet Explorer Collection 1.6.0.6 that is flawed?

  • Spring MVC 3.0 Rest problem

    - by Gidogeek
    Hi Guys, I'm trying out Spring MVC 3.0 for the first time and like to make it RESTfull. This is my controller: @Controller @RequestMapping(value = "/product") @SessionAttributes("product") public class ProductController { @Autowired private ProductService productService; public void setProductValidator(ProductValidator productValidator, ProductService productService) { this.productService = productService; } @RequestMapping(method = RequestMethod.GET) public Product create() { //model.addAttribute(new Product()); return new Product(); } @RequestMapping(method = RequestMethod.POST) public String create(@Valid Product product, BindingResult result) { if (result.hasErrors()) { return "product/create"; } productService.add(product); return "redirect:/product/show/" + product.getId(); } @RequestMapping(value = "/show/{id}", method = RequestMethod.GET) public Product show(@PathVariable int id) { Product product = productService.getProductWithID(id); if (product == null) { //throw new ResourceNotFoundException(id); } return product; } @RequestMapping(method = RequestMethod.GET) public List<Product> list() { return productService.getProducts(); } } I have 2 questions about this. I'm a believer in Convention over Configuration and therefor my views are in jsp/product/ folder and are called create.jsp , list.jsp and show.jsp this works relatively well until I add the @PathVariable attribute. When I hit root/product/show/1 I get the following error: ../jsp/product/show/1.jsp" not found how do I tell this method to use the show.jsp view ? If I don't add the RequestMapping on class level my show method will be mapped to root/show instead of root/owner/show how do I solve this ? I'd like to avoid using the class level RequestMapping.
