Linkedin 登录:无法检索访问令牌:appId 或重定向 uri 与授权码不匹配或授权码已过期

Linkedin signin: Unable to retrieve access token : appId or redirect uri does not match authorization code or authorization code expired

我在 http://localhost/index.php 中有以下按钮:

<a href="https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=123456789&state=adasd8asd8sad&scope=r_basicprofile&redirect_uri=http://localhost/linkedin.php">Linked in</a>

然后在 redirect_url 我有以下 php 代码:

<?php
$data = array(
    'client_id'     => '123456789',
    'client_secret' => 'abcdefghijklm',
    'grant_type'    => 'authorization_code',
    'code'          => $_REQUEST['code'],
    'redirect_uri'  => 'http://localhost/index.php',
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.linkedin.com/uas/oauth2/accessToken');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

$result = curl_exec($ch);

var_dump($result);die;

然而这会导致:

string(263) "{"error_description":"missing required parameters, includes an invalid parameter value, parameter more than once. : Unable to retrieve access token : appId or redirect uri does not match authorization code or authorization code expired","error":"invalid_request"}"

我还想说的是,点击link后,最多2秒到linkedin.php中的代码为运行。所以它在 linkedin 要求的 20 秒之内。所以真的不能过期

Linkedin 中的开发人员控制台:

配置的重定向网址为: http://localhost/linkedin.phphttp://localhost/index.php

'client_id' => '123456789'(模糊), 'client_secret' => 'abcdefghijklm'(模糊)

默认应用程序权限:r_basicprofile

谁能看出我为什么会出现这个错误?

当您调用 /accessToken 端点时,您必须指定与初始 /authorization 请求相同的 redirect_uri 值。参见OAuth2 RFC。现在你的价值观不同了:

  • http://localhost/linkedin.php
  • http://localhost/index.php
