我有一个带有 POST 方法的 Scalatra API，该方法由发送 gzip 编码消息的外部 API 调用。但是我无法读取 post 请求的正文，当我尝试读取 POST 的正文或尝试对其进行解压缩时，出现异常：

MalformedInputException: Input length = 1.

如果我将传入的 POST 请求路由到 fiddler，fiddler 会正确处理消息并声明消息已编码，解码后，我可以在请求的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))

同样的异常被抛出：

logger.info(s"Response body..." + request.body )

我也尝试将正文读取为 json，但它返回 JNothing：

logger.info(s"Response body...\n${parsedBody}" )

这是 POST 标头：

(Expect,100-continue)
(Connection,keep-alive)
(Content-Encoding,gzip)
(Content-Type,application/json)
(Content-Length,3500)

这是堆栈区域的一部分：
