验证时未找到404

Question

我们的应用程序是在Nginx / 1.14.0和Centos 7上的Code Igniter 3 + PHP 7中开发的，并且config.php文件的详细信息如下

$config['base_url'] = 'http://myurl.com/';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

nginx服务器块如下

server {
    listen       80;
    server_name  localhost;

    root   /usr/share/nginx/html;
    index  index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

当我检查nginx access.log文件时，我得到了

"POST /Authentication/login HTTP/1.1" 404 162 "http://myurl.com/"

当我们尝试登录该应用程序时，出现404错误。该站点在Apache上运行良好，但在Nginx中运行不正常。这必须是配置问题。请指教。
