最后，我使用curl登录到wp管理页面，并向每个错过二维码的帖子发送了一个请求。

<?php

$curl = curl_init();

//---------------- generic cURL settings start ----------------
$header     = array(
      "Referer: https://my.wordpress.com/wp-login.php",
"Origin: https://my.wordpress.com",
"Content-Type: application/x-www-form-urlencoded",
"Cache-Control: no-cache",
"Pragma: no-cache",

      );


curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);

curl_setopt($curl, CURLOPT_COOKIEFILE, \'cookies.txt\');
curl_setopt($curl, CURLOPT_COOKIEJAR, \'cookies.txt\');

$url = \'https://my.wordpress.com/wp-admin\';
curl_setopt($curl, CURLOPT_URL, $url);

$post = \'log=user&pwd=my-safe-password&wp-submit=Log+In&redirect_to=https%3A%2F%2Fmy.wordpress.com%2Fwp-admin\';
curl_setopt($curl, CURLOPT_POST, TRUE);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);

$output = curl_exec($curl);

$url = \'https://my.wordpress.com/wp-admin/post.php?post=123&action=edit\';
curl_setopt($curl, CURLOPT_URL, $url);
$output = curl_exec($curl);


curl_close ($curl);

echo ($output);
