GET HTTP BODY

version 2004

GET HTTP BODY (body)

The GET HTTP BODY command returns the body of the HTTP request being processed. The HTTP body is returned as is, without processing or parsing.

This command only operates in non-contextual mode. It can be called using a Web database method (On Web Authentication Database Method, On Web Connection Database Method) or any Web method executed in non-contextual mode.

In body, you can pass a variable or a field of the BLOB or Text type. Keep in mind that it is generally preferable to use the BLOB type since the number of characters is not limited. The Text type, on the other hand, is limited to 32,000 characters; if you exceed this amount, any excess data received will be truncated.

This command allows you, for example, to carry out queries in the body of requests. It also permits advanced users to set up a WebDAV server within a 4D database.

In this example, a simple request is sent to the 4D Web server and the contents of the HTTP body are displayed in the debugger. Here is the form sent to the 4D Web server, as well as the corresponding HTML code:

Here is the Test4D2004 method:

   C_BLOB($request)
   C_TEXT($requestText)

   GET HTTP BODY($request)
   $requestText:=BLOB to text($request;UTF8 Text without length)
   SEND HTML FILE("page.html")

Note: This method is declared "Available through 4DACTION, 4DMETHOD and 4DSCRIPT" in its properties.

When the form is submitted to the Web server, the $requestText variable receives the text of the HTTP request body.

GET HTTP HEADER.
