Specific questions:

What should I do if PHP fails to send a POST request?

The POST request sent to Weibo's headline article advanced writing interface failed and no return data was received. The code is modified based on the demo provided by Weibo.
It is feasible if you use Python to send requests.

<?php     // 相关参数
    $data = array(
        &#39;title&#39; => "Test_Title",
        'content' => rawurlencode("Test_Content"),
        'cover' => "https://api.xygeng.cn/bing/1920.php",
        'summary' => "Test_Summary",
        'text' => "Test_Content",
        'access_token' => ""
    );

    // 发送POST请求
    $ch = curl_init ();
    $url = "https://api.weibo.com/proxy/article/publish.json";
    curl_setopt ( $ch, CURLOPT_URL, $url );
    curl_setopt ( $ch, CURLOPT_POST, 1 );
    curl_setopt ( $ch, CURLOPT_HEADER, 0 );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data);
    $ret = curl_exec ( $ch );
    curl_close ( $ch );
    echo $ret;

How should the PHP code be modified?

Solution:

First use echo curl_error($ch); to see what the error is?

Then it may be the reason for https. When requesting, set https trust and do not check https.
