nginx的坑-org.apache.http.TruncatedChunkException: Truncated chunk( expected size: 7752; actual size: ...

org.apache.http.TruncatedChunkException: Truncated chunk

项目中使用请求远程接口报错 ，项目是Spring-boot的，两个项目（A和B） , A调用B的rest接口，返回json数据，A系统报错如下异常，B系统没有报错。
记录一下处理方式，方便再次遇到这个问题的人

当系统报以上错误时，接口表现出来的是数据传输不完整， 比如说接口返回 json ， 那么接收到的数据可能会少一截，json 数据说不定会少个 ｝ ，此时json就无法反序列化了。说白了就是丢包了。

通过大半天的查找，终于定位到是nginx的问题，因为nginx处理chunked传输有问题。
所以最简单的处理方式是把nginx的缓存关闭。
