我创建了一个简单的测试grpc服务器(java,spring)来测试这项技术。
当试图从服务器调用函数时,我得到一个错误{“error”:“2 unknown:stream removed”}
blumrpc错误图像
在应用程序内部,没有打印堆栈跟踪,我无法使用断点对我不可见的代码捕获程序执行

syntax = "proto3";

package com.example.grpc;

message LoginRequest{
  string login =1;
  string password =2;
}
message LoginResponse{
  string token = 1;
}

service LoginService{
  rpc login(LoginRequest) returns (LoginResponse);
}

这是我的原始文件

我的grpc服务

@GRpcService
public class LoginServiceImpl extends LoginServiceGrpc.LoginServiceImplBase {
    @Override
    public void login(com.example.grpc.LoginServiceOuterClass.LoginRequest loginRequest,
                      StreamObserver<LoginServiceOuterClass.LoginResponse> responseObserver){
        com.example.grpc.LoginServiceOuterClass.LoginResponse response = com.example.grpc.LoginServiceOuterClass.LoginResponse
                .newBuilder().setToken(UUID.randomUUID().toString()).build();
        responseObserver.onNext(response);
    }
}

我不能解释问题的真正根源,但是帮助我的是为服务器和grpc提供了不同的端口,希望它能帮助一些人


## Server Properties

server:
  port: 6789
  compression.enabled: true
  max-http-header-size: 20000
