Disqus API 创建帖子错误

我在使用 Disqus API 尝试对 tumblr 中发布的出版物发表评论时遇到问题。 这是代码：

<?php
    ini_set('display_errors', 'on');

    $thread="XXXXXXXXX"; // e.g., 455718495 — you'll need to also create a $forum and pass that if you know only the thread's URL or identifier rather than the ID
    $api="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // Generate one at http://disqus.com/api/applications/ -- Secret key is required for anonymous comment posting
    $message="Hello world."; // this is the content of the comment, i.e., what you'd normally type in the postbox
    $author_email="[email protected] /cdn-cgi/l/email-protection"; // optional, including this will still make the comment a guest comment, but it will now be claimable 
    $author_name="user"; // optional, can be any display name you like
    $fields_string=""; // DO NOT EDIT

    // set POST variables
    $url = 'http://disqus.com/api/3.0/posts/create.json'; // full documentation at http://disqus.com/api/docs/posts/create/
    $fields = array(
        'api_secret'=>urlencode($api), // change to api_key when using a public key
        'thread'=>urlencode($thread),
        'message'=>urlencode($message),
        'author_email'=>urlencode($author_email),
        'author_name'=>urlencode($author_name),
    );

    foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
    rtrim($fields_string,'&');
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_POST,count($fields));
    curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);

    // execute POST
    $result = curl_exec($ch);

    // close connection
    curl_close($ch);

?>

当您运行代码时，我会传递所需的值，如 api_key、您想要评论的消息、线程 ID、邮件和用户名 php 给我以下错误：

{"code": 4, "response": "You must be authenticated to perform this action"}

我该如何解决这个错误？

默认情况下，Disqus API 应用程序现在设置为使用 OAuth，因此您必须为此示例添加“access_token”参数。有两种获取访问令牌的方法：

1. 使用我们的 OAuth 流程并让用户使用其 Disqus 帐户登录 - 您不会包括author_name or author_email如果你使用这个方法
2. 使用您的网站所有者访问令牌（针对访客评论执行此操作，如上面的示例所示）

以下是有关 OAuth 与 Disqus 配合使用的文档：http://disqus.com/api/docs/auth/ http://disqus.com/api/docs/auth/-- 请注意，站点所有者的访问令牌可以在您的应用程序概述中找到：http://disqus.com/api/applications/ http://disqus.com/api/applications/

以下是如何让用户进行身份验证，然后为您提供访问令牌的示例：https://github.com/disqus/DISQUS-API-Recipes/tree/master/php/oauth https://github.com/disqus/DISQUS-API-Recipes/tree/master/php/oauth

获得访问令牌后，脚本应如下所示：

<?php
    ini_set('display_errors', 'on');

    $thread="XXXXXXXXX"; // e.g., 455718495 — you'll need to also create a $forum and pass that if you know only the thread's URL or identifier rather than the ID
    $api="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; // Generate one at http://disqus.com/api/applications/ -- Secret key is required for anonymous comment posting
    $message="Hello world."; // this is the content of the comment, i.e., what you'd normally type in the postbox
    $author_email="[email protected] /cdn-cgi/l/email-protection"; // optional, including this will still make the comment a guest comment, but it will now be claimable 
    $author_name="user"; // optional, can be any display name you like
    $fields_string=""; // DO NOT EDIT
    $access_token="YOUR_ACCESS_TOKEN";

    // set POST variables
    $url = 'http://disqus.com/api/3.0/posts/create.json'; // full documentation at http://disqus.com/api/docs/posts/create/
    $fields = array(
        'api_secret'=>urlencode($api), // change to api_key when using a public key
        'thread'=>urlencode($thread),
        'message'=>urlencode($message),
        'author_email'=>urlencode($author_email),
        'author_name'=>urlencode($author_name),
        'access_token'=>urlencode($access_token),
    );

    // rest of script ...
?>
