go语言实现爬虫(三)

添加grpc

简单编写proto文件：

syntax = "proto3";
option go_package = "./;proto";

service Crawler {
    rpc Start (StartReq) returns (TaskInfoResp) {}
    rpc Stop (TaskInfoReq) returns (TaskInfoResp) {}
    rpc Status (TaskInfoReq) returns (TaskInfoResp) {}
    rpc Pause (TaskInfoReq) returns (TaskInfoResp) {}
    rpc Resume (TaskInfoReq) returns (TaskInfoResp) {}
    rpc Result (TaskInfoReq) returns (TaskInfoResp) {}
}

message StartReq {
    string taskID = 1;
    repeated string urls = 2;
    int32 threads = 3;
    int32 timeout = 4;
    int32 depth = 5;
}

message TaskInfoReq {
    string taskID = 1;
}

message TaskInfoResp {
    int32 code = 1;
    string msg = 2;
    repeated string data = 3;
}
