Ajax request PHP Error 404 But the script will be able to output the problem of data resolution method

1. Scene

Ajax requests that the PHP script return a 404 status Code, but the PHP script can output the data, causing the Ajax callback function to fail to execute.

Troubleshooting process:

1, the suspicion is that the framework of their own problems, in the browser window request Ajax Request script path, the page can open normally.

2, write a PHP script, directly output a JSON-formatted string, with the AJAX request, still return the status code of 404.

3. Write an HTML page with an AJAX request and return a status code of 405.

4, troubleshooting Nginx configuration parameters, found that there are problems with fastcgi configuration.

Workaround:

Location ~ \.php$ {            root           html;            Fastcgi_pass   127.0.0.1:9000;            Fastcgi_index  index.php;            Fastcgi_param  script_filename  /scripts$fastcgi_script_name;            Include        fastcgi_params;        }

Change to

Location ~ \.php$ {            root           /www;            Fastcgi_pass   127.0.0.1:9000;            Fastcgi_index  index.php;            Fastcgi_param  script_filename  /www/$fastcgi _script_name;            Include        fastcgi_params;        }

What to modify:

Root runs the root directory for the Web site.

/scripts changes to the Web site root directory.
