Mailchimp API 错误 - 对一直有效的代码的错误请求

Question

我们最近切换到新服务器，现在我突然收到 mailchimp 的发送活动端点错误。

活动创建时没有任何问题，但发送后出现以下错误。关于可能导致此问题的任何想法？

    <HTML><HEAD>
<TITLE>Bad Request</TITLE>
</HEAD><BODY>
<H1>Bad Request</H1>

Reference&#32;&#35;7&#46;640be8ac&#46;1610827794&#46;1757979e
</BODY>
</HTML>

下面是我的PHP代码

$ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, 'https://'.$this->oauthData['oauth_api_endpoint'].'.api.mailchimp.com/3.0/campaigns/'.$campaignID.'/actions/send');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_TIMEOUT, 10);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_ENCODING , "gzip");
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                    'Accept: application/vnd.api+json',
                    'Content-Type: application/vnd.api+json',
                    'Authorization: OAuth ' . $this->oauthData['oauth_token']
            ));
        curl_setopt($ch, CURLOPT_USERAGENT, $cuseragnet);
        $result = curl_exec($ch);

Answer 1

必须通过一个空数组

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(array()));
