我有一个带有POST方法的Scalatra API，它由发送gzip编码消息的外部API调用 . 但我无法读取post请求的正文，当我尝试读取POST的主体或尝试解压缩时，我得到了异常：
MalformedInputException: Input length = 1.
如果我将传入的POST请求路由到fiddler，则fiddler正确处理消息并声明消息已编码，并且在解码后，我可以在请求正文中看到正确的消息
这是我尝试过的事情：
val body = new GZIPInputStream(new ByteArrayInputStream(request.body.getBytes))
抛出相同的异常：
logger.info(s"Response body..." + request.body )
我也尝试将身体作为json读取，但它返回JNothing：
logger.info(s"Response body...\n${parsedBody}" )
这是POST Headers ：
(Expect,100-continue)
(Connection,keep-alive)
(Content-Encoding,gzip)
(Content-Type,application/json)
(Content-Length,3500)
这是堆栈的一部分：
Parsing the request body failed, because:
