Web (vi)---fastcgi advanced (Request and response)

Next to the section, the last section only responds---cout, this section gets the query_string of the address bar, and then responds.

I. Req_resp.cpp.

#include <stdlib.h>#include<string.h>#include<unistd.h>#include"fcgio.h"#include"fcgi_config.h"using namespacestd;intMain (void){    intCount =0; LongPID =Getpid (); Streambuf* Cin_streambuf =Cin.rdbuf (); Streambuf* Cout_streambuf =Cout.rdbuf (); Streambuf* Cerr_streambuf =Cerr.rdbuf ();    Fcgx_request Request;    Fcgx_init (); Fcgx_initrequest (&request,0,0);  while(Fcgx_accept_r (&request) = =0{fcgi_streambuf cin_fcgi_streambuf (request).inch); Fcgi_streambuf cout_fcgi_streambuf (Request. out);        Fcgi_streambuf cerr_fcgi_streambuf (Request.err); Cin.rdbuf (&cin_fcgi_streambuf); Cout.rdbuf (&cout_fcgi_streambuf); Cerr.rdbuf (&cerr_fcgi_streambuf); cout<<"content-type:text/html\r\n"                "\ r \ n"                ""<< PID <<""                ""<< ++count <<""; cout<<"";  for(inti =0; Request.envp[i]; ++i) {Char* Findquerystr =NULL; Findquerystr= Strstr (Request.envp[i],"query_string"); if(findquerystr) {cout<< Request.envp[i] <<'\ n';    }}} cin.rdbuf (CIN_STREAMBUF);    Cout.rdbuf (COUT_STREAMBUF);    Cerr.rdbuf (CERR_STREAMBUF); return 0;}

Two. Compile and run.

#g + o req_resp req_resp.cpp-i/usr/local/include-l/usr/local/lib-lfcgi-lstdc++-lfcgi++

#./Req_resp

If there is a compile or runtime error (typically a library problem), refer to the previous section of the workaround.

Three. Copy the CGI to Ngix (the target path is not created manually)

CP ***/req_resp/usr/local/nginx/cgibin

Four. Start spawn-fcgi.

/usr/local/nginx/sbin/spawn-fcgi-a 127.0.0.1-p 8088-f/usr/local/nginx/cgibin/req_resp

Five. Access.

Note: Python index.py is already running in the case.

Browser Address bar: localhost/req_resp.cgi?his_is_from_brower_input&hello=1&world=2

Note that the query_string displayed is the content after the Address bar question mark.

The browser appears as:

pid:4072

Request Number:2

Request Environment

query_string=this_is_from_brower_input&hello=1&world=2
