有两个服务部署在Kubernetes集群中。Service_1提供了REST API，其中一部分是文件内容上传的方法，所以使用了 "Content-Type: multipart/form-data "的POST请求。 从Service_2发送的真实请求的例子是。
Request DefaultFullHttpRequest(decodeResult: success, version: HTTP/1.1,
content: UnpooledHeapByteBuf(freed))
POST /engine-rest/deployment/create HTTP/1.1
Accept: application/json
User-Agent: process
Content-Type: multipart/form-data; boundary=28319d96a8c54b529aa9159ad75edef9
Content-Length: 4028
Host: service.cluster.ip:8080
该请求不能被处理，并以异常形式失败。
