VS 2008 How To Make A POST Request
Oct 8, 2009
I am using visual studio 8, using vb.net. I am trying without success to make a post request to a web form as shown below.
<?xml version="1.0" encoding="UTF-8"?><postBetOrder xmlns="urn:betfair:games:api:v1"marketId="2568540" round="1" currency="GBP"><betPlace><bidType>BACK</bidType><price>2.5</price><size>2.50</size><selectionId>658440</selectionId></betPlace>

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'm trying to use the web request class in vb.net to post some xml. On the reciving end, I keep getting an internal server error with the message: Missing Soap action header". I did some reasearch and saw that a firewall can strip out the soap action header so I tried running it with no firewall and got the same result. I tried adding a soap action header using the header command, and that didn't even get to the server to receive an error message.

I want to create an integer sequence in each page request.Here is my code:
Public Class Test
Inherits System.Web.UI.Page
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load[code]....
My requirements are just created the sequence using VB.NET code and of no database help. The sequence must be started at 1 and incremented by 1. My attempt to solve this is by using STATIC variable within the Page_Load which can retain the sequence value.But someone told me that my approach is risky because it's not thread safe. Is that true? Or how do I create a sequence for each request that is free from any problems be it thread safe or others?
UPDATE: I attempted to solve the problem another way. But I'm not sure the thread safety of my new solution. Here is my code, the call to Singleton.Instance.Sequence function will generate a new sequence value:
Public NotInheritable Class Singleton
Private Sub New()
End Sub[code]......

I want to develop a program that uses an online API, with GET and POST requests, and I want to know how to make the requests within the program (without the user seeing a web page), and then download the results into the program so I can parse them

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.

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.

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]

the page at [URL] provides a high bit rate quantum number generator web service and I'm trying to access that service.
However I could not manage to do so.
This is my current code:
CODE:
I'm having 403 forbidden error when I try to do a get request on [URL].
After debugging abit, I've realised that even though I've supplied a valid username and password, the response html that was sent after my POST request indicate that I was actually not logon to the system after my POST request.
Does anyone know why is this the case, and how may I work around it to call the service? Bump. can anyone get this to work or is the site just a scam?

There's a certain website I need to access multiple times each day that requires me to enter my login name/password first, every time. To save some time, I copied-and-pasted the HTML source code and pre-populated the text fields with my info, then saved that to my desktop. Now I can just open that doc in my browser and click "submit" without having to type anything.

I wanted to use HttpGet here so that the result can be cached.

I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?

Does anyone at least have some related links on fetch requests and scraping?I 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.[code]
