Facebook Instant Articles:使用图表创建文章 API

Facebook Instant Articles: Creating Articles with Graph API

我一直在开发一个使用 Facebook API 来创建即阅文的 WordPress 插件。 (我使用的是此处的 SDK 版本 5.3.1:https://github.com/facebook/php-graph-sdk/tree/5.4)它需要包含许多自定义字段,因此需要使用新插件而不是使用现有插件。我使用 Vagrant/VirtualBox linux 服务器在我的本地计算机上开发了它,从那里我能够成功地进行身份验证并创建一个 Instant Article,然后它出现在 Facebook 的列表中,在 Publishing Tools > Instant Articles 中> 开发文章.

我将相同的代码部署到实时 Web 服务器以继续测试它。身份验证仍然成功,但当我尝试从该服务器发布文章时,即时文章从未创建,也没有出现在 Facebook 的列表中。

令人费解的是,两次尝试的响应看起来几乎相同。一个区别是 accessToken 值,我将其标记为 {access_token}。我标记为 {different}.

的响应之间的其他差异

任何人都可以帮助我理解为什么在 PHP 或 API 响应中没有任何明显错误的情况下一个成功而另一个失败?

使用本地计算机响应(成功):

    ["eTag":protected]=>
    NULL

  }
  ["thrownException":protected]=>
  NULL
}

感谢CBroe's suggestion in his comment I was able to discover the cause of the problem. After making a request to get the article import status,我在响应中发现了这个错误信息:

["body":protected]=>
  string(439) "{"errors":[{"level":"ERROR","message":"Unclaimed URL: The URL http:\/\/www.example.com\/my-article-url\/ has not been claimed for Instant Articles. Please check to make sure you have a URL registered for your page. For more information refer to URLs in the Publishing Articles section of the Instant Articles documentation."}],"status":"FAILED","id":"{some_id}"}"

然后我意识到,在构建 Instant Article 标记的函数中,我在标记上做了一个 str_replace,这样我的本地测试域名将被替换为正确的 "claimed"域名。由于我们已将代码部署到新域,因此没有发生这种替换,并且 Facebook 在标记中发现了不正确的 "unclaimed" 域。

通过将新域名添加到要替换的名称数组中,我能够将标记发送到具有 "claimed" 域的即阅文。我的文章创建成功!

非常感谢 CBroe,我快疯了。
