Nginx+ThinkPHP+Vue解决跨域问题的方法详解

解决过程主要有两个步骤。

1.nginx配置允许跨域

在你部署的网站对应的端口配置文件里设置，我的目录结构是这样的：

server {
listen 8080;
server_name localhost;
root "D:/phpstudy_pro/WWW/admin/landpage_server/public";
location / {
index index.php index.html error/index.html;
error_page 400 /error/400.html;
error_page 403 /error/403.html;
error_page 404 /error/404.html;
error_page 500 /error/500.html;
error_page 501 /error/501.html;
error_page 502 /error/502.html;
error_page 503 /error/503.html;
error_page 504 /error/504.html;
error_page 505 /error/505.html;
error_page 506 /error/506.html;
error_page 507 /error/507.html;
error_page 509 /error/509.html;
error_page 510 /error/510.html;
include D:/phpstudy_pro/WWW/admin/landpage_server/public/nginx.htaccess;
autoindex off;
}
location ~ \.php(.*)$ {
fastcgi_pass 127.0.0.1:9002;
fastcgi_index index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi_params;
}

# 添加跨域配置
location / {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
}
}

不过这有个坏处，就是每次你重启的时候就会被默认配置覆盖。所以这里有第二种办法：

或者在你的ThinkPHP项目的 nginx.htaccess 文件里配置。（我通过小皮将网站部署后会自动生成这个文件），上面那个文件会把这个配置文件引入进来。 include D:/phpstudy_pro/WWW/admin/landpage_server/public/nginx.htaccess;

#伪静态配置
location / {
    index  index.html index.htm index.php;
    autoindex  off;
    if (!-e $request_filename) {
        rewrite  ^(.*)$  /index.php?s=/$1  last;
        break;
    } 
}


 # 添加跨域配置
        location / {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
            if ($request_method = 'OPTIONS') {
                add_header 'Access-Control-Allow-Origin' '*';
                add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
                add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
                add_header 'Access-Control-Max-Age' 1728000;
                add_header 'Content-Type' 'text/plain charset=UTF-8';
                add_header 'Content-Length' 0;
                return 204;
            }
 }

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

server {

listen 80;

# 域名

server_name localhost;

# 服务器根目录

root H:\php\project\UserManager\public;

# 默认读取的文件

index index.php index.html index.htm;

location / {

# 允许浏览器跨域请求

if ($request_method = 'OPTIONS') {

add_header Access-Control-Allow-Origin '*';

add_header Access-Control-Allow-Headers '*';

add_header Access-Control-Allow-Methods '*';

add_header Access-Control-Allow-Credentials 'true';

return 204;

}

if (!-e $request_filename) {

rewrite ^(.*)$ /index.php?s=/$1 last; break;

}

try_files $uri $uri/ /index.php?$query_string;

}

# 监听127.0.0.1:9000端口，要和php-cgi.exe配置的ip:端口一致

location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

}

其中的“允许浏览器跨域请求”是关键点，因为浏览器在发现网页请求是跨域请求时，会再发送一个OPTIONS请求，只有这个请求成功了才会允许跨域请求，此时，要强行配置允许跨域。（这里配置的是允许全部请求跨域）

2.在ThinkPHP中允许跨域

编辑middleware.php文件

<?php

// 全局中间件定义文件

return [

//允许跨域

//\think\middleware\AllowCrossDomain::class

\app\middleware\AllowCrossDomain::class

// 全局请求缓存

// \think\middleware\CheckRequestCache::class,

// 多语言加载

// \think\middleware\LoadLangPack::class,

// Session初始化

// \think\middleware\SessionInit::class

];

<?php

declare (strict_types = 1);

namespace app\middleware;

use Closure;

use think\Config;

use think\Request;

use think\Response;

/**

* 跨域请求支持

*/

class AllowCrossDomain

{

protected $cookieDomain;

protected $header = [

'Access-Control-Allow-Credentials' => 'true',

'Access-Control-Max-Age' => 1800,

'Access-Control-Allow-Methods' => 'GET, POST, PATCH, PUT, DELETE, OPTIONS',

'Access-Control-Allow-Headers' => 'Token, Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-CSRF-TOKEN, X-Requested-With',

];

public function __construct(Config $config)

{

$this->cookieDomain = $config->get('cookie.domain', '');

}

/**

* 允许跨域请求

* @access public

* @param Request $request

* @param Closure $next

* @param array $header

* @return Response
