php - get_file_contents：HTTP 请求失败！HTTP/1.1 400 错误请求

Question

我正在尝试使用 Microsoft 帐户身份验证，但登录请求只返回“400 错误请求”。

参考：

• https://wiki.vg/Microsoft_Authentication_Scheme
• https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow

<?php
  if(isset($_GET['code'])) {
    $content = http_build_query(
      array(
        'client_id' => 'MY-CLIENT-ID',
        'client_secret' => 'MY-SECRET',
        'code' => $_GET['code'],
        'grant_type' => 'authorization_code',
        'redirect_uri' => 'https://www.MY-DOMAIN.com/auth'
      )
    );

    $opts = array('http' =>
      array(
        'method' => 'POST',
        'header' =>
          'Accept: application/json' . "\r\n" .
          'Content-Type: application/x-www-form-urlencoded' . "\r\n" .
          'Content-Length: ' . strlen($content) . "\r\n",
        'content' => $content
      )
    );

    $context = stream_context_create($opts);

    if (false !== ($tokenContents = @file_get_contents("https://login.live.com/oauth20_token.srf", false, $context)))
      echo $tokenContents;
    else
      var_dump(error_get_last());
  }
?>
