I am trying to simulate a FileUpload with Chrome Postman to my ASP.NET WebApi method . To do this I perform the following steps in Postman.
1.Open postman and choose POST method from address bar.
2.Enter valid URL.
3.Go to Body section below address bar.
4.From Body section choose Binary option.
5.Hit the "Chose Files" button to select a file to upload.
6.Choose a file
7.Ensure the "Post" option is selected
8.Hit "Send"
I then test for MultiPartContent, however when I step through my method the Request Object doesn't appear to have the info that I need . The exception below will get hit.
public List<Premium.Model.BureauModUpdate> Post() {
HttpRequestMessage request = this.Request;
if (!request.Content.IsMimeMultipartContent()) {
throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
}
}
It doesn't appear as if any info concerning the file upload is in the request. A review of the request content yields this:
{Method: POST, RequestUri: 'http://localhost/WCAPI/Lookup/BureauModUpdate/CreateNyModUpdates', Version: 1.1, Content: System.Web.Http.WebHost.HttpControllerHandler+LazyStreamContent, Headers:

Is there something else I need to be doing ? If anybody has any suggestions or can point me in the right direction on this it would be greatly appreciated.
I believe your content type is incorrect. It should be multipart/form-data when uploading files.
application/x-www-form-urlencoded is used only when posting a form with no binary data.

You can use the below code as per the values in your URL.
if your URl is = http://localhost:3039/test.aspx?valuestr=abc&randomnum=99389
then you can use the below code
string valuestr = Request.QueryString["valuestr"];
string randomnum= Request.QueryString["valuestr"];
Response.Write(valuestr );
Response.Write(randomnum);
do let me know in case you require any help

You can instantiate a CookieContainer and set it to the CookieContainer property of your HttpWebRequest. Then make an initial request and after you GetResponse the cookie container will be populated with any cookies returned.
Then reuse the CookieContainer in subsequent requests and all the previous returned cookies will be sent.
I was wondering if I could get some help with this. A service is sending a POST request to my controller and I am trying to get the encoded URL so I can store the information in my database. Unfortnately I dont know exaclty what type of object it is I can use in order to refer to this encoded XML
This is the feed that is being sent by the service to my controller method:

As you can see the ResponseXML parameter is set to an encoded XML. I need to extract this information from this parameter decoded, deserialize it and take some of the nodes.
This is my controller method:
public ActionResult GeneratingXMLFormResponse(XmlDocument xmlResponse)
{
var form = xmlResponse;
return View("EfileView");
}
The xmlResponse does not have the information that I need.
What object can I use in order to refer to the parameter ResponseXML?
Hey guys I figured out how to do this.
If your parameter and XML are coming in the body of your resposen you can receive it in your controller method as a string. After receiving the string you can transform that string into an XML like so:
[HttpPost, ValidateInput(false)]
public string GeneratingXMLFormResponse(string responseXML)
{
XmlDocument xml = new XmlDocument();
xml.LoadXml(responseXML);
}
This is a follow-up question to the suggestion of user #Kiewic to make a post request using a webview: Post data with a request in a Windows Store app WebView - using C#
So I am using this code
// defined before: string uri, User user
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, new Uri(uri));
request.Content = new HttpStringContent(
String.Format(
"language={0}&session_id={1}&user_id={2}",
Text.GetLanguage(),
user.session_id,
user.user_id.ToString()
),
Windows.Storage.Streams.UnicodeEncoding.Utf8,
"application/x-www-form-urlencoded"
);
webView.NavigateWithHttpRequestMessage(request); // webView defined in xaml
Fiddler shows me this request:
POST http://mobile.mysite.com/ HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Accept-Language: en-US,en;q=0.8,de-CH;q=0.5,de;q=0.3

language=en&session_id=fhihferihguiegierewfrefghxrfer&user_id=1
The webserver technology is PHP, so I used this code to print the post content
<?php
var_dump($_POST);
?>
But the result is an empty array. So where is my mistake?
According to a Microsoft employee there is a bug with setting the headers of the request content. This should mean that nothing is wrong with my code in the first post:
http://social.msdn.microsoft.com/Forums/windowsapps/en-US/7deaf4ba-611f-4957-af3c-9b2b2e1e1b8b/webviewnavigatewithhttprequestmessage-set-contenttype?forum=winappswithcsharp
This means you cannot really use NavigateWithHttpRequest and you should use another approach to post data. User #Kiewic made a suggestion which works on Windows 8 too:
Post data with a request in a Windows Store app WebView - using C#
I'm trying to establish a connection to a server that sends 401 Authentication Error for all my requests along with the normal html response. e.g.
However, I also want to read the HTML response that is sent alongwith so that I can parse that. An example header exchange captured using LiveHTTPHeaders:
Clearly, content-length is non-zero. Firefox shows it to be javascript.

WebResponse loginResponse = loginRequest.GetResponse();
throws an exception.
I will be grateful for any suggestions to help me get to the actual content.
Thanks.
You need to read the WebException's Response property, like this:
WebResponse loginResponse;
try {
loginResponse = loginRequest.GetResponse();
} catch(WebException ex) {
if (ex.Status == WebExceptionStatus.ProtocolError) {
loginResponse = ex.Response;
} else
throw;
}
//Do something with the response, and remember to dispose it.
