Send POST Body With HTTP Request?
May 3, 2010
I have used the WinHttp.WinHttpRequest object in VB6 to make HTTP POST requests many times. It works great: .Open the URL, then .SetRequestHeader (however many are needed) and then .Send the body. The .Send method makes the actual connection and sends everything to the server at once.How to I emulate this behavior in .NET? The examples I've tried with System.Net.HttpWebRequest open a stream with .GetRequestStream() and then write the body to the stream. Unfortunately, the server is responding immediately to the .GetRequestStream method and therefore never sees the POST body.I am obviously trying to connect up some legacy stuff here, but am having a hard time Googling the problem or finding another approach in .NET.

I'm trying to send a HTTP request to a servers interface.But I'm really confused about how to specify the parameters I want to send to the servers interface method. What I've done so far.My server interface only accepts POST requests, that's why I'm using POST and asked if something is wrong with the way I use the parameters.
Dim parameters As String = "?text=test&type=person"
Dim buffer As Byte() = Encoding.UTF8.GetBytes(parameters)
Dim WebReq As HttpWebRequest = CType(WebRequest.Create(NameRecPage), HttpWebRequest)
'NameRecPage is the url

I am trying to send a POST request to add some content to an API box. The rules are that the body format should be XML(values must be XML-escaped), HTTP Method (post), requires authentication(yes), request content(content-type: "application/xml". [code] Best practice is to incrementally add and remove changes to your entry list instead of deleting/recreating the entire list each time a change is necessary.New entries are placed at the top of the queue for polling and are processed in a LIFO manner.

When you search on google most of the examples are very vague, hopefully this thread can make it to the top and will help someone looking for the same info.to explain the code what it does is create a long string by concatenating all the values together stores it in the variable finalString and then hashes the string using the SHA5 algorithm. Then its supposed to send the string (finalString) as a post request to the url.The server im sending it to reads it this way and sends a response. [code]

I am trying to write this program that logs into this website. Now I figured out how to make the http "POST" request to the specific spot on the page which returns a "Successfully logged in" afterwards but once I make a request to another part of the page, it asks me to login (I look at the source code). I have been messing with Fiddler and I compared the a POST from my webbrowser to a POST from my program. I found the following lines to be in my browser POST and not in my program post:

I am assuming this has something to do with the cookie that I am suppose to get to be able to tell the website that I am logged in. If someone could point me in the right direction that would be great. I dont use XMLHTTPREQUEST in my program. I found it earlier on the msdn website but now I cant find a reference to it.I am also not good with term names and I just started learning VB and don't know much about cookies/HTTP requests and such, but that is why I am trying to learn.

I've an annoying ASP.NET problem:
I have a Perl script (see below), which gets the form_info variable. Now unfortunately, it's http POST, and not http GET, so Request.Querystring doesn't work...
Now I have to replace the Perl Script with an asp.net page/app, but my problem is that I cannot process the string form_info when I don't have the string... and I cannot change the http POST to a HTTP get, since it's generated by a 3rd party java applet.

I'm attempting to update a legacy VB6 component (not written by me) to the .NET platform. There is one function which posts an XML string to a URL:
Function PostToUrl(ByRef psUrl, ByRef psData, Byref psResponseText, ByRef psErrorMsg, ByRef psUsername, ByRef psPassword)
On Error Resume Next
Dim objWinHTTP
[CODE]...
I've updated this to:
Public Function PostXml(ByVal XML As String) As Boolean
Try
Dim URL As String = My.Settings.NTSPostURL
'TODO: supply username and password! '
[CODE]...
However when I run the .NET code the server returns the error '403 Forbidden - protocol error' on the line: Using Response As HttpWebResponse = DirectCas (HTTPRequest.GetResponse(), HttpWebResponse). The VB6 code runs fine. identify any discrepancies between the two that might be causing this?

Is there any way we could get directly say the 1000 characters after the first 5000 characters, skipping everything before that after sending in an HTTP request to an HTTPS page using either GET or POST in VB.NET? The reason why I ask this question is because in one of the webpage I am trying the get through my program, the website is sending response data in chunks with the first chunk containing some javascript garbage that I have no interest in, the only data I care is in the second chunk and
how to get the second chunk after receiving the first one since it is within the same HTTP request.It would save some time and Internet traffic if I can skip the first chunk that I do not need.Is that possible or I am just day dreaming?
ADDED: Here is how a typical header of the response I am getting from the webpage I am trying to get:
Date: Mon, 20 Jun 2011 13:21:56 GMT
Set-Cookie: JSESSIONID=1AF1AF9EF936E1CB2FA85B750EDC67C4; Path=****some path******; Secure
Content-Type: text/html; charset=ISO-8859-1[code].....
Not sure if that helps, but as you can see, the chunk size is not visible to me, there is no "Trailer" in the header as well.

Okay, i've tried httpwebrequest, webclient, and a couple of others methods; using the headers parameter of each to set headers and then either opening a response stream or simply setting the system.net.webclient method to download a response into a string. Put simply, how do I make a simple GET request with a few headers and read the data back! I am very, very stuck in a hole right now..
