我有以下 protobuf 定义:
service MyService {
rpc ServiceMethod (ServiceMethodRequest) returns (ServiceMethodResponse) {}
}
message ServiceMethodRequest{
string requestParam = 1;
}
message ServiceMethodResponse{
Error error = 1;
SomeObjectList data = 2;
}
message Error{
string code = 1;
string errorMessage = 2;
}
message SomeObject {
string myobject = 1;
}
message SomeObjectList {
repeated SomeObject myobjects = 1;
}
如您所见,我想返回格式化响应,因此我的 API 有一些标准化的响应方式。我像这样格式化了我的回复(由于可读性,这是 JSON 格式):
{"error":{"code":"-1","errorMessage":""},"data":{"myobjects":[{"myobject":"some string"},{"myobject":"another string"}]}}
但在客户端,我不断得到:
{ Error: 2 UNKNOWN: Unknown Error
at Object.exports.createStatusError (.../node_modules/grpc/src/common.js:91:15)
at Object.onReceiveStatus (.../node_modules/grpc/src/client_interceptors.js:1204:28)

at callback (.../node_modules/grpc/src/client_interceptors.js:845:24)
code: 2,
metadata: Metadata { _internal_repr: {}, flags: 0 },
details: 'Unknown Error' }
当我尝试 console.log 响应对象时。
我究竟做错了什么?另外,是否有任何关于 grpc 的好书以及一些示例(C、C#、Java、Python、JavaScript)?提前致谢!
