Build New HTTP Request data in just few lines of code

The HttpRequest component allows easy creation of request data in any formats including "multipart/form-data", "application/www-form-urlencoded", "text/xml" or any custom format.

You can add each form value manually as well as extract and create them from existing HTML source, URL or HTML page with FORM controls saved to the file.

// [Delphi]
html.Add('<form action="" method="post">');
html.Add('<input type="text" name="username" value="John">');
html.Add('<input type="file" name="userfile">');
html.Add('<input type="submit" name="submit" value="submit"> </form>');

httpClient.Post('', clHttpRequest1, response);

// [C#]
httpRequest1.Items.AddFormField("username", " John");
httpRequest1.Items.AddSubmitFile("userfile", "c:\\");

httpClient.Post("", httpRequest1, response);

See Build Form Post Request for more details.

Build HTTP Request data in IDE design-time

With HttpRequest you can create Form Post or Submit File requests without writing a single line of the code.

Simple put the component on to the form and choose the desired option within the component editor in Delphi or component menu in Visual Studio: "Build by Url", "Build by File" or "Build by Text". After that the HttpRequest component will create all necessary request data and automatically change the HTTP header values.
