Hello,  
I’m working on a modul, that should get a POST request with XML-RPC data  
and then send a response.  
I have problem with getting the request\_body. It’s no problem to read  
headers and find Content-Type: text/xml. But when I want to read the  
request\_body there is no one. I use the same code as the function for  
reading request\_body in ngx\_http\_variable.  
My modul is a handler (something like circe\_gif module). When my module  
is filter and the request is passed to the proxy module I can read the  
request body in my filter module.  
Is it possible to read headers and the request\_body and then generate a  
response by handlers?

Thank you,  
Michal

Yes. You have to use ngx\_http\_read\_client\_request\_body() function  
and generate response in post\_handler callback (the one you’ve  
passed to function).

See e.g. proxy or dav modules for examples.

After using ngx\_http\_read\_client\_request\_body() function, my handler  
works correctly.

Thanks, Michal
