I try to implemente a module based on NGINX, which will filter the
of request body.
Now, I met a problem: I can not get the whole request body
my code is as following:
len = rb->buf->last - rb->buf->pos ;
post_content = ngx_palloc(r->pool, len + 1);
ngx_cpystrn(post_body, rb->buf->pos, len);
it seems that if the body size is over 256 Bytes, we can not get the
request body length.
my questions are:
- how can I get the correct length of request body ?
- Do I need copy the request body to a buffur and then filter? Does
serverar buff hold the data and link the buff-chain ?
I want to redirect some unsafe URLs to different safe URL, like
http://www.abc.com/a.index redirect to http://www.1234.com/a.index
http://www.abc.com/b.index rediect to http://www.5566.com/b.index
I use the function: ngx_http_internal_redirect() to implementate, but
always get a crash.
Any idea about these ?
