thinkphp5.1+uni-app接口开发中跨域问题解决方案

一般而言，在public/index.php中只需要加入以下三行代码即可解决

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: token,Origin, X-Requested-With, Content-Type, Accept');
header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE');

但是使用微信或微信开发者工具访问时post提交数据还是会提示跨域，所以修改后完整代码如下

<?php
// [ 应用入口文件 ]
namespace think;

// 加载基础文件
require __DIR__ . '/../thinkphp/base.php';

if (isset($_SERVER['HTTP_ORIGIN'])) {
    // Decide if the origin in $_SERVER['HTTP_ORIGIN'] is one
    // you want to allow, and if so:
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');    // cache for 1 day
}

// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        // may also be using PUT, PATCH, HEAD etc
        header("Access-Control-Allow-Methods: GET, POST, OPTIONS");

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

    exit(0);
}

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: token,Origin, X-Requested-With, Content-Type, Accept');
header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE');
// 支持事先使用静态方法设置Request对象和Config对象

// 执行应用并响应
Container::get('app')->run()->send();
