Re: [ANN] ngx_echo v0.35: ability to POST/PUT local files as subrequest bodies


Thanks so much for your detailed answer. Works like a charm :)

But i see i can't access this from LUA?

, or echo_subrequest_async directives. This won't be fixed in the future due to technical problems :)

but is it possible to get 
echo_request_body
directly in nginx LUA?

Thanks.

 Hello,  any chance to debug the -f function? I use the debug log, but get no information about the file... /body1 shows me "test" but /body2 shows nothing... no error, no body content...  
 Because there's no error in your /body2 request, no log is expected to be printed ;)  
     location /body1 {            echo_subrequest POST /sub -b 'test';        }       location /body2 {            echo_subrequest POST /sub -f /tmp/hello.txt;        }         location /sub {            echo "body: $echo_request_body";        } 
 Why $echo_request_body is empty for /body2? Because "echo_subrequest /sub -f /tmp/hello.txt" produces a request body that consists of *file* buffers only (such that nginx does not bother reading the whole disk file into RAM at once) and $echo_request_body only respects pure *memory* buffers.  The following example comes from the ngx_echo's test suite:      location /main {         echo_subrequest POST /sub -f html/blah.txt;     }      location /sub {         echo "sub method: $echo_request_method";         # we don't need to call echo_read_client_body explicitly here         echo_request_body;     }  where html/blah.txt contains the following contents:      Hello, world  Then GET /main gives      sub method: POST     Hello, world  Cheers, -agentzh  _______________________________________________ nginx mailing list nginx@nginx.org http://nginx.org/mailman/listinfo/nginx
