Retrieving data from a POST method in ASP.NET

I am using ASP.NET.

There is a system that needs to POST data to my site and all they asked for is for me to provide them with a URL. So I gave them my URL http://www.example.com/Test.aspx.

Now I do not know exactly how they POST it but now on my Test.aspx page I need to write code that will save that data to a database.

But how would this work and what must I do on my Test.aspx page?

I wrote some code in my Page Load Event that sends开发者_如何学Python me an email on Page Load to see if they actually hit the page and it does not seem like they are even?

The data from the request (content, inputs, files, querystring values) is all on this object HttpContext.Current.Request
To read the posted content

StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
string requestFromPost = reader.ReadToEnd();

To navigate through the all inputs

foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
   string value = HttpContext.Current.Request.Form[key];
}

You can get a form value posted to a page using code similiar to this (C#) -

string formValue;
if (!string.IsNullOrEmpty(Request.Form["txtFormValue"]))
{
  formValue= Request.Form["txtFormValue"];
}

or this (VB)

Dim formValue As String
If Not String.IsNullOrEmpty(Request.Form("txtFormValue")) Then
    formValue = Request.Form("txtFormValue")
End If

Once you have the values you need you can then construct a SQL statement and and write the data to a database.

You need to examine (put a breakpoint on / Quick Watch) the Request object in the Page_Load method of your Test.aspx.cs file.
