  • Asp.net HttpWebResponse - how can I not depend on WebException for flow control?

    - by Campos
    I need to check whether the request will return a 500 Server Internal Error or not (so getting the error is expected). I'm doing this: HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; request.Method = "GET"; HttpWebResponse response = request.GetResponse() as HttpWebResponse; if (response.StatusCode == HttpStatusCode.OK) return true; else return false; But when I get the 500 Internal Server Error, a WebException is thrown, and I don't want to depend on it to control the application flow - how can this be done?

  • django auth_views.login and redirects

    - by Zayatzz
    Hello I could not understand why after logging in from address: http://localhost/en/accounts/login/?next=/en/test/ I get refirected to http://localhost/accounts/profile/ So i ran search in django files and found that this address is the default LOGIN_REDIRECT_URL for django. What i did not understand is why it gets redirected to there. I guessed, that my login form's post address should be : /accounts/login/?next=/en/test/ instead of /accounts/login/ I wrote it into template and it worked. But since the redirect url changes dynamically, how can i make this login post forms address change dynamically too? is there a templatetag for that or something? Alan

  • Can YQL parse web sites requiring cookie-based authentication?

    - by user249488
    First, my use case: I'm trying to use YQL's built in XPATH capabilities to scrape content from Yahoo! Fantasy Sports. It uses some sort of cookie-based authentication scheme. Basically, the sequence is: 1) Do an HTTP GET on the Yahoo! Login page 2) Parse the hidden inputs from the response and do an HTTP PUT with your Yahoo! Login on the form URL 3) Use the cookies returned from step 2 to GET any of the Fantasy Sports! websites that you have access to My question is, does YQL support doing this to scrape data? The only authentication based examples I've seen use OAuth, but I haven't seen any examples of using YQL to parse websites with cookie-based authentication schemes

  • Using multilingual and localeurl in django

    - by Dmitry A. Erokhin
    Using dajngo-multilingual and localeurl. Small sample of my main page view: def main(request): #View for http://www.mysite.com/ name = Dog.objects.all()[0].full_name #this is a translated field return render_to_response("home.html", {"name" : name}) Entering http://www.mysite.com/ redirects me to http://www.mysite.com/ru/ and "name" variable gets russian localization. For now it's ok... But... Entering http://www.mysite.com/en/ shows me same russian loclized variable. During my experiments with debuger I've discovered: request.LANGUAGE_CODE is changing properly according to /en/ or /ru/ url suffix (thanx to localeurl) invoking multilingual.languages.set_default_language() makes "name" variable change loclization The question is: should I change language of django-multilingual to request.LANGUAGE_CODE in each of my view myself, or it must be solved automaticly and I've done something wrong?

  • Django admin urls return INVALID REQUEST! - Django

    - by RadiantHex
    Hi folks, my admin urls are sat behind a prefix by doing the following. 1# (r'^admin/', include(admin.site.urls)), is placed within urls_core.py 2# (r'^api/', include('project.urls_core')), is palced within urls.py All admin URLs work fine except app indexes.

  • Google Chrome - NETWORK_IP_ADDRESSES_CHANGED - pages only partially load

    - by Julian
    Hi Google Chrome version (8.0.552.224 (Official Build 68599)) I have developed a web site using asp.net mvc and jquery. it uses a lot of ajax. I noticed that occasionally a web page does not complete loading all files from the server. Browsing through forums It seems that this also happens to other people. Looking in to the Chromium Net-Internals ( type: chrome://net-internals/ as a url in the chrome browser ) I noticed that the pages do not complete loading if a NETWORK_IP_ADDRESSES_CHANGED event occurred. Any files that were not fetched from the server before the time of the NETWORK_IP_ADDRESSES_CHANGED event failed to arrive with error (-3) Do you know why the NETWORK_IP_ADDRESSES_CHANGED event occurs? Is there a way to stop it from happening? Thanks and be happy, Julian

    - by Roland
    I'm doing a ajax call via the normal jquery ajax funtion My ajax looks as follows jQuery('#yt10').live('click',function(){jQuery.ajax({'data':{'set':$("#booking_set_id1").val(),'setStat':$("#booking_stockStatus").val(),'setNum':$("#booking_setNum").val()},'beforeSend':function(){ if($("#booking_set_id1").val() == "" || $("#booking_stockStatus").val() == "" || $("#booking_setNum").val() == ""){ $("#error").addClass("flash-error"); $("#error").html("Please fill in all relevant set details before adding a set"); return false; } },'dataType':'html','success':function(data,status){ $("#mainrow").show(); $("#error").removeClass("flash-error"); $("#error").html(""); $("#setTable tr:last").after(data); $("#booking_set_id1").val(""); $("#booking_stockStatus").val(""); $("#booking_setNum").val(""); },'url':'/booking/newSet','cache':false});return false;}); Now the function newSet needs to echo javascript to the bowser but somehow jquery filters the javscript out.

  • How to create widget with clickable text in QT/PyQt?

    - by serge
    Hi everyone, i'm trying to realize non-editable QTableView with widgets in cells that should contain clickable listed text. With following code i'm setting widget in definite cell: view = QTableView() label = QLabel( <some html text> ) ... view.setIndexWidget(index, label) I used html to make label's text clickable, but links became blue with underline and moreover by clicking on it with right mouse button appears popup menu with "Copy Link Locaion" option, where i wanted to place some hidden information instead of url and of course do not let user see this info. I'm looking for light-weight widget, i thought that insertion of QGraphicsView in each cell will lead to big computer loads, but can't think of any other solution. Can you advice what should i use for this purpose? Thank you in advance Serge

  • ExpressionEngine: {exp:query} producing error

    - by Josh Brown
    Hi. I have this code in place to pull some relation data from the database based on a ID of another weblog entry. The relationship custom field would not work for my situation. I have tested the SQL with MySQL and get no errors. But I get an error when I pull up the page. {exp:query sql="SELECT entry_id,field_id_16,field_id_19 FROM exp_weblog_data WHERE field_id_15='2' AND weblog_id='6'"} Also, I want to populate the “field_id_15” from the url. I have tried using the “segment_*” tag, but nothing. Maybe it is something else. Any help is greatly appreciated. Thanks, Josh

  • CSS for https urls

    - by Vincent
    Hello, looking for some help with images referenced within the stylesheet. I have no problems with these from non secure locations within the site but only from https. The stylesheet loads fine and displays everything correctly except for the images. example: body { margin: 0; padding: 0; background: url(/img/background_tile.gif) top left repeat-x; text-align: center; background-color: #fff; } All my css files and other image paths inside the code use relative urls to images. How can I make sure they all work fine without hard coding my image paths with https or http? I want the code to work fine with http and https. Thanks

  • Client Side Includes on HTML pages

    - by Roy Rico
    Previously I had thought that there were only ways to get content from external URLs into your page. These 2 ways are use an IFRAME or Javascript to include it into your pages. I've just learned of a new way using the tag. <object type="text/html" frameborder="0" data="http://Server/URL/"></object> I have found some content online that confirms this ability, but it doesn't talk much about features such as Accessibility and SEO of the page. Does anyone have any experience with this? Is there any information available regarding using this method and how it effects Accessibility and SEO?

  • Removing http301 redirect from client's cache

    - by ChessWhiz
    Hi, I have a server/client architecture where the client hits the ASP.NET server's service at a certain host name, IP address, and port. Without thinking, I logged on to the server and set up permanent HTTP301 redirection through IIS from that service to another URL that the machine handles via IIS (same IP and port), mistakenly thinking it was another site that is hosted there. When the client hit the server at the old host name, it cached the permanent redirect. Now, even though I have removed the redirection, the client no longer uses the old address. How can I clear the client's cache so that it no longer stores the redirect? I have read about how permanent HTTP301 can be, but in this case, it should be possible to reset a single client's knowledge of the incorrectly-learned host name. Any ideas?

  • Setting user agent of a java URLConnection

    I'm trying to parse a webpage using Java with URLConnection. I try to set up the user-agent like this: java.net.URLConnection c = url.openConnection(); c.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2"); But the resulting user agent is the one I specify, with "Java/1.5.0_19" appended to the end. Is there a way to truly set the user agent without this addition?

  • Strange HtmlUnit behavior (bug?)

    - by roddik
    Hello. Take a look at this: WebClient client = new WebClient(); WebRequestSettings wrs = new WebRequestSettings(new URL("http://stackoverflow.com/ping/?what-the-duck?"), HttpMethod.HEAD); client.getPage(wrs); Running this code results in throwing FileNotFoundException, because HTTP Status code on the page is 404 and getting the same page again with the GET method, with User-Agent set to Java-.... Why does it GET the page (it doesn't happen with "normal" status codes)? Is this a bug? Thanks Here is the entire server response: HTTP/1.1 404 Not Found Cache-Control: private Content-Length: 7502 Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 Date: Thu, 11 Feb 2010 14:12:11 GMT Where does it tell client to GET something? And how can I force WebClient to ignore it? Here's a screenshot of HTTPDebugger: The problem here is I don't understand why the second request is being sent and why is it sent with different useragent.

  • Most useful Rails plugins, Ruby libraries and Ruby gems?

    - by Srinivas Iyer
    I have seen many sites which provide the whole list of Rails plugins, Ruby libraries and Ruby gems, but we hardly use few of them and some may not suit our requirement and we spend a whole lot of time searching for useful plugins which suits our requirement. I have created this poll, people can post useful libraries, gems and plugins which they have come across. It would be great help for newbies like me and to the entire Ruby on Rails community. Note: to keep this poll as useful as possible, please remember: Post only one library, gem, or plugin per answer Mention the name of the library, gem, or plugin which you find it useful. URL of the location of the resource We don't want duplicate answers, so before posting check if the library has been mentioned already. Thanks

  • jQuery won't parse my JSON from AJAX query

    - by littlecharva
    Hi, I'm having difficulty parsing some JSON data returned from my server using jQuery.ajax() To perform the AJAX I'm using: $.ajax({ url: myUrl, cache: false, dataType: "json", success: function(data){ ... }, error: function(e, xhr){ ... } }); And if I return an array of items then it works fine: [ { title: "One", key: "1" }, { title: "Two", key: "2" } ] The success function is called and receives the correct object. However, when I'm trying to return a single object: { title: "One", key: "1" } The error function is called and xhr contains 'parsererror'. I've tried wrapping the JSON in parenthesis on the server before sending it down the wire, but it makes no difference. Yet if I paste the content into a string in Javascript and then use the eval() function, it evaluates it perfectly. Any ideas what I'm doing wrong? Anthony

  • mutidimensional array from javascript/jquery to ruby/sinatra

    - by user199368
    Hi, how do I pass a 2-dimensional array from javascript to ruby, please? I have this on client side: function send_data() { var testdata = { "1": { "name": "client_1", "note": "bigboy" }, "2": { "name": "client_2", "note": "smallboy" } } console.log(testdata); $.ajax({ type: 'POST', url: 'test', dataType: 'json', data: testdata }); } and this on server side: post '/test' do p params end but I can't get it right. The best I could get on server side is something like {"1"=>"[object Object]", "2"=>"[object Object]"} I tried to add JSON.stringify on client side and JSON.parse on server side, but the first resulted in {"{\"1\":{\"name\":\"client_1\",\"note\":\"bigboy\"},\"2\":{\"name\":\"client_2\",\"note\":\"smallboy\"}}"=>nil} while the latter has thrown a TypeError - can't convert Hash into String. Could anyone help, or maybe post a short snippet of correct code, please? Thank you

  • How to add parameters to HttpURLConnection using POST

    - by Michal Švácha
    I am trying to do POST with HttpURLConnection(I need to use it this way, can't use HttpPost) and I'd like to add parameters to that connection such as post.setEntity(new UrlEncodedFormEntity(nvp)); where nvp = new ArrayList<NameValuePair>(); having some data stored in. I can't find a way how to add this ArrayList to my HttpURLConnection which is here: HttpsURLConnection https = (HttpsURLConnection) url.openConnection(); https.setHostnameVerifier(DO_NOT_VERIFY); http = https; http.setRequestMethod("POST"); http.setDoInput(true); http.setDoOutput(true); the reason for that awkward https and http combination is the need for not verifying the certificate. That is not a problem, though, it posts. But I need it to post with arguments. Any ideas? Thanks a lot!

  • Quick question about PayPal IPN Security

    - by Alix Axel
    PayPal IPN sends a POST request with a variable number of fields to the notify URL, in order to confirm that the POST request is legit we need to resubmit the same request along with a additional cmd=_notify-validate field to PayPal, which then replies SUCCESS or FAILURE. My question is, why do we need to resend the request to PayPal? Wouldn't something like this work? if (preg_match('~^(?:.+[.])?paypal[.]com$~i', gethostbyaddr($_SERVER['REQUEST_ADDR'])) > 0) { // request came from PayPal, it's legit. } Iff we can trust the server to correctly resolve IPs, I assume we can trust PayPal POST requests, no?
