C语言的FastCGI与Nginx的 [英] C language FastCGI with Nginx

问题描述

我试图运行用Nginx的网络服务器后面C语言的FastCGI应用程序。 Web浏览器永远不会完成加载和响应永远不会完成。我不知道如何处理它和调试。任何有识之士将AP preciated。

Hello World应用程序从fastcgi.com抽取并简化看起来是这样的：

 的#includefcgi_stdio.h
＃包括LT＆;＆stdlib.h中GT;INT主要（无效）
{ 而（FCGI_Accept将＆GT; = 0）
 {
  的printf（内容类型：text / html的\\ r \\ n状态：200 OK \\ r \\ n \\ r \\ n）; }  返回0;
}
 

输出的可执行文件与任何一个执行：

  

CGI-FCGI -connect 127.0.0.1:9000的a.out

或

  

产卵-FCGI -a120.0.0.1 -p9000 -n ./a.out

Nginx的配置是：

 服务器{
        听80;
        服务器名称 _; 位置 / {
                        ＃主机和端口的FastCGI服务器
                        根/ home / user中/ WWW;
                        指数的index.html;                        fastcgi_pass 127.0.0.1:9000;
 }
}
 

解决方案

您需要调用 FCGI_Accept将在，而循环：

 而（FCGI_Accept将（）＆GT; = 0）
 

您有 FCGI_Accept将＆GT; = 0 在code。我认为，导致 FCGI_Accept将函数的地址进行比较，以 0 。由于功能存在，该比较是从未假的，但不被调用的功能。

I am attempting to run a fastcgi app written in C language behind the Nginx web server. The web browser never finishes loading and the response never completes. I am not sure how to approach it and debug. Any insight would be appreciated.

The hello world application was taken from fastcgi.com and simplified to look like this:

#include "fcgi_stdio.h"
#include <stdlib.h>

int main(void)
{

 while(FCGI_Accept >= 0)
 {
  printf("Content-type: text/html\r\nStatus: 200 OK\r\n\r\n");

 }

  return 0;
}

Output executable is executed with either one of:

cgi-fcgi -connect 127.0.0.1:9000 a.out

or

spawn-fcgi -a120.0.0.1 -p9000 -n ./a.out

Nginx configuration is:

server {
        listen   80;
        server_name _;

 location / {
                        # host and port to fastcgi server
                        root   /home/user/www;
                        index  index.html;

                        fastcgi_pass 127.0.0.1:9000;
 }
}

解决方案

You need to call FCGI_Accept in the while loop:

while(FCGI_Accept() >= 0)

You have FCGI_Accept >= 0 in your code. I think that results in the address of the FCGI_Accept function being compared to 0. Since the function exists, the comparison is never false, but the function is not being invoked.
