Nginx 提供 C++ cgi 脚本：响应是二进制格式

我正在尝试在 nginx 上运行 C++ CGI 脚本。我使用 FCGIWrap 和来自 nginx 网站的脚本。程序代码如下：

#include <iostream>
using namespace std;

int main ()
{

   cout << "Content-type:text/html\n\n";
   cout << "<html>\n";
   cout << "<head>\n";
   cout << "<title>Hello World - First CGI Program</title>\n";
   cout << "</head>\n";
   cout << "<body>\n";
   cout << "<h2>Hello World! This is my first CGI program</h2>\n";
   cout << "</body>\n";
   cout << "</html>\n";

   return 0;
}

我使用 g++ -o start.cgi start.cpp 进行编译。因此，当我运行 ./start.cgi 时，我得到了正确的输出。但是当我使用 curl localhost/cgi-bin/start.cgi 时，我得到了二进制输出（实际上看到了 cout 响应和类似 GCC 的信息...所以我怀疑它是编译后的可执行文件）

我的nginx.conf：

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /var/www;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location /cgi-bin/*\.cgi {
          gzip off;
          fastcgi_pass unix:/var/run/fcgiwrap.sock;
          include /etc/nginx/fastcgi_params;
          fastcgi_param SCRIPT_FILENAME /var/www/cgi-bin$fastcgi_script_name;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

长话短说，您需要设置您的 cgi 位置以使用正则表达式匹配。

location ~ /cgi-bin/.*\.cgi
