Help, make a post subrequest with response body from parent

hi, angentzh

I use echo module(angentzh) to issue a subrequest(POST method) that 

it’s
body from parent’s request body, and i add some code in
ngx_http_echo_subrequest->ngx_http_echo_parse_subrequest_spec :
so, it’s not work, but change to ‘-b’ or ‘-f’, it’s OK. help ?


if (ngx_strncmp("-h", arg->data, arg->len) == 0) { // add
‘-h’ param
275 to_write = &h_str;
276 expecting_opt = 0;
277 continue;
278 }
279 }
280
281 ngx_log_error(NGX_LOG_ERR, r->connection->log, 0,
282 “unknown option for echo_subrequest_async:
%V”,
arg);
283
284 return NGX_ERROR;
285 }
286
287 if (h_str != NULL && h_str->len) {
288 parsed_sr->query_string = &r->args;
289 if (r->request_body == NULL) {
290 return NGX_ERROR;
291 }
292
293 rb = r->request_body; // make
post
body from parent’s body, is right?
// i track this line by gdb, the r->request_body->buf is
null, and r->request_body->bufs aslo is null.
294
295 } else if (body_str != NULL && body_str->len) {
296 rb = ngx_pcalloc(r->pool, sizeof(ngx_http_request_body_t));
297
298 if (rb == NULL) {
