我只能找到这个相关的问题：https://github.com/square/okhttp/issues/2193,但我已确保Content-Length是响应正文的正确长度.这是我记录的okhttp请求和响应：

服务器与我们的Web和iOS端完美配合.直到大约两个月前,当它突然停止工作而没有网络变化时,它也能很好地与android配合使用.还有什么可能导致此错误？

看起来缓冲区中的数据是可读的,因为从上面的调试器中可以看到可读文本([size = 185 text = {“err_no”：0,“result”：[“Adventure”,“Advice”,“Art”,“非洲“,”Airli …])在缓冲变量之后注释.此外,来自调试器的数据与记录的数据不同：

我使用调试器来跟踪问题,似乎gzipped响应被解压缩了两次.如附图所示,在InflaterSource.java中读取两次.在第二次解压缩时抛出异常.

第一次读取被调用

第二次调用read时,抛出异常
