If it help anyone, my issue is I have to use POSTmethod in curl but no POSTparameters has been require, as API grab value from URL query string only. So, passing empty array in POSTFIELDSfixed my problem. My guess is it depends on Apache/PHP setting on server, whether it allows POSTrequest without post parameters or not.
如果它对任何人有帮助，我的问题是我必须POST在 curl 中使用方法，但不需要POST参数，因为 API 仅从 URL 查询字符串中获取值。所以，传递空数组POSTFIELDS解决了我的问题。我的猜测是这取决于服务器上的 Apache/PHP 设置，是否允许POST不带 post 参数的请求。
