前端上传图片不列举了，主要说下后端遇到的问题：

1，一直报错， "errcode": 47001,后来看了下社区，其实应该是改下content type，代码如下：

    $url = "https://api.weixin.qq.com/wxa/img_sec_check?access_token=".$accessTocken;
    $post_data = array("media"=>"@".$upload_path_origin.$name); 
    $headers = array("Content-type: application/octet-stream");// 这里很重要！！！
    $post_json_data = json_encode($post_data);   
    // echo $post_json_data; 
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_json_data);
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers ); 
    $output = curl_exec($ch);
    curl_close($ch);
    echo $output;
