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);
}

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);
}
}
已成功生成所有grpc类

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
