在做微信上傳素材檔案時出了點問題，伺服器提示media缺失，原上傳程式碼如下：

function https_request($url,array $data = null) {
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        if ($data){
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        }
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($curl);
        curl_close($curl);
        return $output;
    }
 

$data['media'] = @.'file.path';

在網上找了一堆資料之後，有人的建議是在設定fields之前關閉安全上傳操作，程式碼如下

curl_setopt ( $curl, CURLOPT_SAFE_UPLOAD, false);

意思時該設定項已經不被支援。

之後在官方文件上找到：

具體程式碼如下：

function postFile($url,$path,$others=null){
        $ch = curl_init($url);
        $cfile = new \CURLFile($path);

        $others or $others = [];
        $others['media'] = $cfile;
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_POST,1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $others);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        $output = curl_exec($ch);
        curl_close($ch);
        return $output;
    }
