我正在WSO2 ESB中创建一个JSON有效负载。但是最近我注意到在点击端点时，它在消息体的开头和结尾添加了一些额外的字段。因此，JSON结构正在改变，结果无法生成实际结果。从普通日志中看不到额外字段，但如果启用http wire log，则可以注意到这些字段。我正在粘贴下面的代码以及电线日志。

当它到达端点时，我记录了启用线路的请求。

在日志的第二行中显示值 44d ，在第二行中显示附加的值零，该值未在有效负载中的任何位置提供。我已从系统所有者确认，对于这两个垃圾值，只有请求失败。请建议一种方法来获得这两个领域的芦苇。提前致谢。
答案 0 :(得分：1)
最后这个零与有效负载返回客户端的方式有关，这就是“分块”传输。
（参见：https://en.wikipedia.org/wiki/Chunked_transfer_encoding）
简而言之，44d只是这个“块”的一部分字节数。最后一个“0”意味着没有更多的块。
答案 1 :(得分：1)
您可以在将请求发送到后端服务器之前使用：<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>。
这样可以正常工作......
