Need to have the server make a POST to an API, how do I add POST values to a WebRequest object and how do I send it and get the response (it will be a string) out?I need to POST TWO values, and sometimes more, I see in these examples where it says string postData = "a string to post"; but how do I let the thing I am POSTing to know that there is multiple form values?

I have a remote website and it requires login id and password to enter and i want to enter into that website with httpwebrequest. How it is possible?
View 1 RepliesI am trying to implement the webrequest get and post methods. I am accessing a secure site that requires login authentication and was told that instead of sending a login request all the time; login to the site and capture the cookie and use this to send it in the header to get results from the page. In other words let us use google for example. Lets say google required u to login before searching for something. Now I login through my browser and leave the site logged in. Now I send a httwebrequest from my program that includes the cookie authentication details in the request header and get results for say ?param=sports. Now when I increment the page number like &page=3, I am still only getting page 1 results.
Here is some code:

Now I am using the request method GET. This is in the actual request header from the original request.

I'm trying to make an executable in VS2008 that will read a webpage source code using a vb.NET function into a string variable. The problem is that the page is not *.html but rather *.aspx.
I need a way to execute the aspx and get the displayed html into a string. The page I want to read is any page of this type: [URl]
I have tried the following code, which works properly for html pages, but generates the wrong source code with "access denied" for the page title when I pass in the above aspx page.
Dim myReq As WebRequest = WebRequest.Create(url)
Dim myWebResponse As WebResponse = myReq.GetResponse()
Dim dataStream As Stream = myWebResponse.GetResponseStream()
Dim reader As New StreamReader(dataStream, System.Text.Encoding.UTF8)
Dim responseFromServer As String = reader.ReadToEnd()
AJAX is under the same origin policy. Is there a clean way to use ajax to post data to a remote .aspx page and get response ?
View 2 RepliesI am using an Zencoder API to transcode video files. Once the job is completed they will do a HTTP POST with XML or JSON data containing the Job ID and other info to the url we provide.
So if URL is www.abc.com/GetZencoderResponse.aspx or .ashx, how can I read the data they post?
excuse me for the underlines, i thought that would make my query stand out.
What wrong with this code?

I have a button that when clicked, will generate a PDF and write it out to the response.This is the basic structure of the code:

Downloading the file works fine, except that it doesn't complete the postback.If I were to throw an exception above file.Transmit, the error handling would work properly and I would see the message get displayed in my browser. However, if there is an exception after the file.Transmit then nothing happens. The user saves/opens the pdf and the page does not reload.How can I make it so that the postback always completes, that way I can display an appropriate message to the user?
What I have?I have a ASP.NET page which allows the user to download file a on a button click. User can select the file he wants from a list of available files (RadioButtonList) and clicks on download button to download it. (I should not provide link for each file that can be downloaded - this is the requirement).What I want?I want the user to download multiple files one by one by selecting the required radio button and clicking on the button.What problem am I facing?I can download the file for the first time properly. But, after downloading, if I select some other file and click on the button to download it, click event of the button does not post back and the second file will not be downloaded.I use the follwoing code on the button click event:
protected void btnDownload_Click(object sender, EventArgs e)
{
string viewXml = exporter.Export();
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=views.cov");
Response.AddHeader("Content-Length", viewXml.Length.ToString());
Response.ContentType = "text/plain";
Response.Write(viewXml);
Response.End();
}

I am working in coordination with the pHp developer, he is sending me some username, key at my aspx page and on that basis i am checking the authenticity from the DB, if authentic user then i'll do response.write("YES"), if not then i'll do response.write("NO"). The PHP developer saying that he will read my response.write and on that basis he will allow the user to get logged in to his PHP site. i want to know how will he read My response.write from ASPX page. He was saying he will read it, and will put it in session, i am very confused how will he read my response.write.

I am developing a web application which uses a third party Web service. It requires Username & Password in SOAP Header request. I am passing those credentials well and the web service returns an XML string in Response and also a SESSION ID in the SOAP Header.
I don't know how to read/access the soap header from the response sent from the web service.
I have an user view model that has the following properties:
public User user;
public List<Language> Languages;
I send the above model to the view and use html helpers to build the form, so I end up with something like:
<form action="/Users/Edit/5" method="post"><input id="user_UserId" name="user.UserId" type="hidden" value="5" />
First Name
Last Name
Email
Language
Now, I try to read the POST in something that initially was something like :
[AcceptVerbs( HttpVerbs.Post )]
public ActionResult Edit( int UserId, FormCollection form ) {
and cannot get the user.UserId variable, user.FirstName variable etc.
what needs to be done to be able to read this kind of POST request. I'm kind of reluctant to modifying my ViewModel as it is very simple and easy to maintain as it is.
I guess it doesn't matter what technology I use, but I'm wanting to send an email to a specified email address then have some service either POST to a webpage or Insert into an open SQL database.

I am trying to "behind the scenes" log myself into a website, from the VB code behind my ASP.NET website. But I am dumbfounded as to how to do this.
As far as I know I should be using the WebRequest or Webclient class. That is about as much as I know. I am not sure how to use the class.
I want to click a button on my website and have its Click event send a username and password to another website. This other site isot affiliated with mine. I realize the concept may seem stupid, but I plan on taking this further later, but Just need to know this now.
I have MVC application (applies to non MVC as well) where a user is posting in data. I need to take this data, send it off to two seperate end points (one using a WebRequest form POST and one using a Web Service), parse the result, and send the result back to the original user.
The issue at hand is that both end points take about 20-30 seconds to respond (response is a string) which means that I should probably execute these two calls asynchronously. At the same time I want to wait to respond to the original user until I get both results back. I am guessing I might have to use some sort of object lock so the response does not get sent back before the two calls are complete?
Based on the responses I decided to go with async controllers since I am already working with a MVC application.
I have an .Net Framework #4.0 application that makes a large number of web requests using the WebRequest/WebResponse classes , as i see it has memory leak (or maybe i am doing something wrong)I Wrote some small simple application that demonstrates this:
class Program
{
public static void Main(string[] args)[code]...
The only one solution i came up with is use GC.Collect() (unmarked in example) , All the object are disposed , all streams are closed , am I missing something ?I found something but i don't understand the reason , if i minimize Console the memory usage decreases and looks O.K , what can be the reason for that is there a problem with Conosole or WinForm .
I'm trying to connected to a third-party server, that allows API access via XML post/response. I've created just a very simple test page with a button to press.... the button should just go to the URL, log in with basic authentication and then return the response. if I use a browser and go to the URL, I see the XML response. Usuing my app, I'm still getting 401 unauthorized. I've been at this for hours, I've searched the forums and googled extensively, still no luck. Also, this is an internal app to internal server so security is not the highest priority. I'm setting the UN and PWD for authentication in a simple form.
Here's my VB code behind:
Dim request As HttpWebRequest
Dim response As HttpWebResponse = Nothing
Dim reader As StreamReader
Dim result As String
'disables self-signed SSL cert errors
[Code] ....
And the username and password are 100% accurate - as I mentioned above the code (well, implied).
I feel like this SHOULD be pretty easy: Overall request for testing: Submit a web request to a URL, disable the SSL check (self-signed certs used), login with basic UN and PWD I supply, return the response to a textbox.
