亲测配置nginx-1.13.7(目前最新版)解决只能访问url最后为.php的问题
1.解决.php后面加各种控制时出错，（如访问http://laeni/index.php/index/index/index时,nginx会去"/index.php/index/index/index"目录找导致出错）location ~ \.php {
            root           $root;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            
            set $script $uri;
            set $path_info "";
            if ($uri ~ "^(.+\.php)(/.+)") {
                set $script $1;
                set $path_info $2;
            }
            #fastcgi_index    index.php?IF_REWRITE=1;
            fastcgi_index    index.php;
            fastcgi_param    PATH_INFO    $path_info;
            fastcgi_param    SCRIPT_NAME    $script;
            include        fastcgi_params;
        }2.解决url中省略".php"时Nginx值当做静态资源解析出错
(1),首先更改配置nginx网站根目录,将 "原来网站根目录/项目名/public"设置为网站的根目录,因为新版thinkphp的入口文件在public目录中
(2)更改nginx配置location / {
            root   $root;
            index  index.php index.html index.htm;
            
            #下面主要是解决在url地址中省略"index.php"时使用的规则
            if ( -f $request_filename) {
                break;
            }
            #如果请求既不是一个文件，也不是一个目录，则执行一下重写规则
            if ( !-e $request_filename) {
                #地址作为将参数rewrite到index.php上
                rewrite ^/(.*)$ /index.php/$1 last;
                break;
            }
        }
