dingtalk.corp.message.corpconversation.asyncsend企业会话消息异步发送，Missing method
一、背景
在做钉钉企业会话异步发送的接口时，按照官方文档，
（1）我先封装好了请求参数类：
AsyncMessage.
java
（2）封装好http请求工具类（用的钉钉官方给的示例代码）：
（3）然后写了一个企业会话异步发送业务类：AsyncSendMessageService.java
（4）最后是测试类：AsyncSendMessageServiceTest.java
源码在后面
二、异常
请求参数中明明有method，可以发送请求后，却报了一个Missing method的错误；
错误信息如下：
com.alibaba.fastjson.JSONException: syntax error, pos 1, json : <?xml version="1.0" encoding="utf-8" ?><error_response><code>21</code><msg>Missing method</msg><sub_msg>http传入的参数加入method字段</sub_msg><request_id>12jrtcf50tcfa</request_id></error_response><!--top010178205069.n.et2-->
