  • Erlang: HTTP GET Parameters with Inets

    - by Ted Karmel
    The following post indicates how to make a simple get http request with Erlang's inets. exploring erlang's http client Sometimes, URLs have GET parameters: http://example.net/item?parameter1=12&parameter2=1431&parameter3=8765 Besides including the parameters in the URL itself, is there a way to create variables and then send them with the request? Example appreciated.

  • Running Endpoint locally could not provide access to API explorer when HTTP proxy is enabled

    - by harik
    I'm using Android Studio(0.5.8) on Window7 x64 for developing my Android App with Google AppEngine backend. If my machine is having direct internet access and I launch backend locally (as DevApp Server) and access my API Endpoints through webbrowser (chrome) it is all working as expected. Accessing api explorer is also working fine from webbrowser. http://localhost:8080/_ah/api/explorer But if I have configured internet through http proxy (in Android Studio and also in webbrowser) then webbrowser displays initial page of backend but can't access endpoint api explorer. And deploying appbackend in Google AppEngine also fails with errors. gradlew backend:appengineUpdate Same is working fine if direct internet access is available (not via http proxy). How can we make it work with http proxy also? Any help is appreciated, Thanks.

  • Unable to HTTP PUT with libcurl

    - by Jesse Beder
    I'm trying to PUT data using libcurl to mimic the command curl -u test:test -X PUT --data-binary @data.yaml "http://127.0.0.1:8000/foo/" which works correctly. My options look like: curl_easy_setopt(handle, CURLOPT_USERPWD, "test:test"); curl_easy_setopt(handle, CURLOPT_URL, "http://127.0.0.1:8000/foo/"); curl_easy_setopt(handle, CURLOPT_VERBOSE, 1); curl_easy_setopt(handle, CURLOPT_UPLOAD, 1); curl_easy_setopt(handle, CURLOPT_READFUNCTION, read_data); curl_easy_setopt(handle, CURLOPT_READDATA, &yaml); curl_easy_setopt(handle, CURLOPT_INFILESIZE, yaml.size()); curl_easy_perform(handle); I believe the read_data function works correctly, but if you ask, I'll post that code. I'm using Django with django-piston, and my update function is never called! (It is called when I use the command line version above.) libcurl's output is: * About to connect() to 127.0.0.1 port 8000 (#0) * Trying 127.0.0.1... * connected * Connected to 127.0.0.1 (127.0.0.1) port 8000 (#0) * Server auth using Basic with user 'test' > PUT /foo/ HTTP/1.1 Authorization: Basic dGVzdDp0ZXN0 Host: 127.0.0.1:8000 Accept: */* Content-Length: 244 Expect: 100-continue * Done waiting for 100-continue ** this is where my read_data handler confirms: read 244 bytes ** * HTTP 1.0, assume close after body < HTTP/1.0 400 BAD REQUEST < Date: Thu, 13 May 2010 08:22:52 GMT < Server: WSGIServer/0.1 Python/2.5.1 < Vary: Authorization < Content-Type: text/plain < Bad Request* Closing connection #0

  • Translating from cURL to straight HTTP requests

    - by Joshua
    What would the following cURL command look like as a generic (without cURL) http request? feedUri="https://www.someservice.com/feeds\ ?prettyprint=true" curl $feedUri --silent \ --header "GData-Version: 2" For example how could such an http request be expressed in the browser address bar? Partucluarly, how do I express the --header information if I were to just type out the plain http request?

  • Chache problem running two consecutive HTTP GET requests from an APP1 to an APP2

    - by user502052
    I use Ruby on Rails 3 and I have 2 applications (APP1 and APP2) working on two subdomains: app1.domain.local app2.domain.local and I am tryng to run two consecutive HTTP GET requests from APP1 to APP2 like this: Code in APP1 (request): response1 = Net::HTTP.get( URI.parse("http://app2.domain.local?test=first&id=1") ) response2 = Net::HTTP.get( URI.parse("http://app2.domain.local/test=second&id=1") ) Code in APP2 (response): respond_to do |format| if <model_name>.find(params[:id]).<field_name> == "first" <model_name>.find(params[:id]).update_attribute ( <field_name>, <field_value> ) format.xml { render :xml => <model_name>.find(params[:id]).<field_name> } elsif <model_name>.find(params[:id]).<field_name> == "second" format.xml { render :xml => <model_name>.find(params[:id]).<field_name> } end end After the first request I get the correct XML (response1 is what I expect), but on the second it isn't (response2 isn't what I expect). Doing some tests I found that the second time that <model_name>.find(params[:id]).<field_name> run (for the elsif statements) it returns always a blank value so that the code in the elseif statement is never run. Is it possible that the problem is related on caching <model_name>.find(params[:id]).<field_name>? P.S.: I read about eTag and Conditional GET, but I am not sure that I must use that approach. I would like to keep all simple.

  • What is the proper way to handle a fully qualified domain in a GET request?

    - by Mark P Neyer
    I'm writing a proxy server. When I use curl to fetch a page, say http://www.foo.com/pants, curl makes the following request: GET /pants HTTP/1.1 When I have curl send that request through my local proxy, curl changes the GET request to: GET http://www.foo.com/pants HTTP/1.1 This change causes the foo.com server return a 404. Is foo.com broken? Or is the fully qualified domain name only meaningful to proxy servers? Should I always strip http://domain from the requests I send out? Thanks!

  • Help with HTTP Intercepting Proxy in Ruby?

    - by Philip
    I have the beginnings of an HTTP Intercepting Proxy written in Ruby: require 'socket' # Get sockets from stdlib server = TCPServer.open(8080) # Socket to listen on port 8080 loop { # Servers run forever Thread.start(server.accept) do |client| puts "** Got connection!" @output = "" @host = "" @port = 80 while line = client.gets line.chomp! if (line =~ /^(GET|CONNECT) .*(\.com|\.net):(.*) (HTTP\/1.1|HTTP\/1.0)$/) @port = $3 elsif (line =~ /^Host: (.*)$/ && @host == "") @host = $1 end print line + "\n" @output += line + "\n" # This *may* cause problems with not getting full requests, # but without this, the loop never returns. break if line == "" end if (@host != "") puts "** Got host! (#{@host}:#{@port})" out = TCPSocket.open(@host, @port) puts "** Got destination!" out.print(@output) while line = out.gets line.chomp! if (line =~ /^<proxyinfo>.*<\/proxyinfo>$/) # Logic is done here. end print line + "\n" client.print(line + "\n") end out.close end client.close end } This simple proxy that I made parses the destination out of the HTTP request, then reads the HTTP response and performs logic based on special HTML tags. The proxy works for the most part, but seems to have trouble dealing with binary data and HTTPS connections. How can I fix these problems?

  • Installing WindowsAuthentication breaks authentication / web.config?

    - by Ian Quigley
    I have a clean Windows 2008 R2 box (on a VM) and have installed IIS 7.5 with default options. I then copied a website to it (from Windows 7, IIS 7) and after a little tweaking the website is working fine. The website is currently using and working with Anonymous Authentication. I have gone back to the Windows Components/Sever Manager, Roles - Security and ticked and installed Windows Authentication. When I check my server in IIS (top level above sites) - Authentication, I see Anonymous Authentication (enabled) ASP.NET Impersonation (disabled) Forms Authentication (disbaled) Windows Authentication (enabled) When I check my default website - Authentication, I see as above but "Retrieving status" and an error dialog saying There was an error while performing this operation. Details: Filename c:\inetpub\wwwroot\screwturnwiki\web.config Line number: 96 Error: This configuration section cannot be used in this path. This happens when the section is being locked at the parent level. Locking is either by default (overriderModeDefault="Deny"), or set explicity by a location tag with overrideMode="Deny" or the legacy allowOverride="False". I have tried hand editing the web.config with no success. UN-installing Windows Authentication happily returns my site to working with Anonymous Authentication, and allows me to enable/disable these three options. FYI. I am using ScrewTurnWiki with the Active Directory plug in.

  • Cache Auth Tokens (or Caching HTTP headers in General) - Best Practices

    - by viatropos
    I'm using the Ruby GData Library to access Google Docs and I recently got the GData::Client::CaptchaError because I was re-logging in with every request. Reading this post, it recommends not logging in with every request, but caching the authentication token. How do I go about doing that correctly? Google says it expires every 24 hours, and it doesn't seem like I should store it in the session, so what should I do? I'm using Ruby on Rails with all this. Thanks so much

  • Django User "per project" group assignation

    - by Ben G
    Hi, Here's my problem : my site has users, which can create projects, and access other user's projects. Each project can assign different rights to users. So, i could have Project A : user "John" is in group "manager" , and Project "B" user "John" is in group "worker". How could I use the Django User authentication model to do that ? From a SQL point a view, what i would like is to be able to add "project_id" in the primary key for the "auth_user_groups" table. I don't think profile is of any help here. Any advice ? UPDATE : "worker" and "manager" are just two examples of the permission group (or "roles") that my application defines. There will be more in the future. Eg : i will probably also have "admin", "reporting", etc...

  • PHP: Cookie only sent to http://www.xxx.com and NOT http://xxx.com

    - by Axel
    Hi, I have a php login which sets 2 cookies once some one login. the problem is that if you login from : http://www.mydomain.com and you go to http://mydomain.com you will find your self not logged in, I think that's because the browser only send the cookies to the first syntax. It's only one domain, the difference is the www. before the domain name, so how to set cookies to the whole domain whatever there is www. or not ? Thanks

  • sshd: How to enable PAM authentication for specific users under

    - by Brad
    I am using sshd, and allow logins with public key authentication. I want to allow select users to log in with a PAM two-factor authentication module. Is there any way I can allow PAM two-factor authentication for a specifc user? I don't want users - By the same token - I only want to enable password authentication for specific accounts. I want my SSH daemon to reject the password authentication attempts to thwart would-be hackers into thinking that I will not accept password authentication - except for the case in which someone knows my heavily guarded secret account, which is password enabled. I want to do this for cases in which my SSH clients will not let me do either secret key, or two-factor authentication.

  • ASP.NET WebAPI Security 3: Extensible Authentication Framework

    - by Your DisplayName here!
    In my last post, I described the identity architecture of ASP.NET Web API. The short version was, that Web API (beta 1) does not really have an authentication system on its own, but inherits the client security context from its host. This is fine in many situations (e.g. AJAX style callbacks with an already established logon session). But there are many cases where you don’t use the containing web application for authentication, but need to do it yourself. Examples of that would be token based authentication and clients that don’t run in the context of the web application (e.g. desktop clients / mobile). Since Web API provides a nice extensibility model, it is easy to implement whatever security framework you want on top of it. My design goals were: Easy to use. Extensible. Claims-based. ..and of course, this should always behave the same, regardless of the hosting environment. In the rest of the post I am outlining some of the bits and pieces, So you know what you are dealing with, in case you want to try the code. At the very heart… is a so called message handler. This is a Web API extensibility point that gets to see (and modify if needed) all incoming and outgoing requests. Handlers run after the conversion from host to Web API, which means that handler code deals with HttpRequestMessage and HttpResponseMessage. See Pedro’s post for more information on the processing pipeline. This handler requires a configuration object for initialization. Currently this is very simple, it contains: Settings for the various authentication and credential types Settings for claims transformation Ability to block identity inheritance from host The most important part here is the credential type support, but I will come back to that later. The logic of the message handler is simple: Look at the incoming request. If the request contains an authorization header, try to authenticate the client. If this is successful, create a claims principal and populate the usual places. If not, return a 401 status code and set the Www-Authenticate header. Look at outgoing response, if the status code is 401, set the Www-Authenticate header. Credential type support Under the covers I use the WIF security token handler infrastructure to validate credentials and to turn security tokens into claims. The idea is simple: an authorization header consists of two pieces: the schema and the actual “token”. My configuration object allows to associate a security token handler with a scheme. This way you only need to implement support for a specific credential type, and map that to the incoming scheme value. The current version supports HTTP Basic Authentication as well as SAML and SWT tokens. (I needed to do some surgery on the standard security token handlers, since WIF does not directly support string-ified tokens. The next version of .NET will fix that, and the code should become simpler then). You can e.g. use this code to hook up a username/password handler to the Basic scheme (the default scheme name for Basic Authentication). config.Handler.AddBasicAuthenticationHandler( (username, password) => username == password); You simply have to provide a password validation function which could of course point back to your existing password library or e.g. membership. The following code maps a token handler for Simple Web Tokens (SWT) to the Bearer scheme (the currently favoured scheme name for OAuth2). You simply have to specify the issuer name, realm and shared signature key: config.Handler.AddSimpleWebTokenHandler(     "Bearer",     http://identity.thinktecture.com/trust,     Constants.Realm,     "Dc9Mpi3jaaaUpBQpa/4R7XtUsa3D/ALSjTVvK8IUZbg="); For certain integration scenarios it is very useful if your Web API can consume SAML tokens. This is also easily accomplishable. The following code uses the standard WIF API to configure the usual SAMLisms like issuer, audience, service certificate and certificate validation. Both SAML 1.1 and 2.0 are supported. var registry = new ConfigurationBasedIssuerNameRegistry(); registry.AddTrustedIssuer( "d1 c5 b1 25 97 d0 36 94 65 1c e2 64 fe 48 06 01 35 f7 bd db", "ADFS"); var adfsConfig = new SecurityTokenHandlerConfiguration(); adfsConfig.AudienceRestriction.AllowedAudienceUris.Add( new Uri(Constants.Realm)); adfsConfig.IssuerNameRegistry = registry; adfsConfig.CertificateValidator = X509CertificateValidator.None; // token decryption (read from configuration section) adfsConfig.ServiceTokenResolver = FederatedAuthentication.ServiceConfiguration.CreateAggregateTokenResolver(); config.Handler.AddSaml11SecurityTokenHandler("SAML", adfsConfig); Claims Transformation After successful authentication, if configured, the standard WIF ClaimsAuthenticationManager is called to run claims transformation and validation logic. This stage is used to transform the “technical” claims from the security token into application claims. You can either have a separate transformation logic, or share on e.g. with the containing web application. That’s just a matter of configuration. Adding the authentication handler to a Web API application In the spirit of Web API this is done in code, e.g. global.asax for web hosting: protected void Application_Start() {     AreaRegistration.RegisterAllAreas();     ConfigureApis(GlobalConfiguration.Configuration);     RegisterGlobalFilters(GlobalFilters.Filters);     RegisterRoutes(RouteTable.Routes);     BundleTable.Bundles.RegisterTemplateBundles(); } private void ConfigureApis(HttpConfiguration configuration) {     configuration.MessageHandlers.Add( new AuthenticationHandler(ConfigureAuthentication())); } private AuthenticationConfiguration ConfigureAuthentication() {     var config = new AuthenticationConfiguration     {         // sample claims transformation for consultants sample, comment out to see raw claims         ClaimsAuthenticationManager = new ApiClaimsTransformer(),         // value of the www-authenticate header, // if not set, the first scheme added to the handler collection is used         DefaultAuthenticationScheme = "Basic"     };     // add token handlers - see above     return config; } You can find the full source code and some samples here. In the next post I will describe some of the samples in the download, and then move on to authorization. HTH
