    * 注意事项
    * 1. 文件请求 $body array                                  Content_type: multipart/form-data
    * 2. 普通请求 $body = http_build_query($body);             Content_type: application/x-www-form-urlencoded
    * 3. JSON请求 $body = json_encode($body);                 Content_type: application/json
    * 4. XML请求  $body = <?xml version="1.0"?>xxx</xml>      Content_type: application/xml
    * 5. And so on...
