测试Protobuf在Http传输测试

Demo：https://github.com/fanlv/ProtobufOnHttpGo

一、编写Proto文件

syntax = "proto3";

// 生成go代码
//protoc --go_out=. user.proto

// 生成oc代码
//protoc --objc_out=. user.proto

package user;


message LoginRequest {
  string username = 1;
  string password = 2;
}

message BaseResponse{
  int64 code = 1;
  string msg = 2;
}


message User{
    string uid = 1;
    string name = 2;
    string logo = 3;
}
message LoginResponse {
    User user = 1;
    BaseResponse baseResp = 255;
}

二、生成目标项目代码

// cd 到user.proto文件目录
// 生成go代码
//protoc --go_out=. user.proto

// 生成oc代码
//protoc --objc_out=. user.proto

三、服务端测试代码

r.POST("/login", func(c *gin.Context) {
    body, err := c.GetRawData()
    if err == nil {
        req := &user.LoginRequest{}
        err = proto.Unmarshal(body, req)
        if err == nil {
            if req.Username == "admin" && req.Password == "123456" {
                err = nil
            } else {
                err = errors.New("login fail")
            }
        } else {
            fmt.Print(err.Error())
        }
    }
    var req *user.LoginResponse
    if err == nil {
        req = &user.LoginResponse{
            User: &user.User{
                Uid:  "0010",
                Name: "admin",
                Logo: "url",
            },
            BaseResp: &user.BaseResponse{
                Code: 1,
                Msg:  "ok",
            },
        }
    } else {
        req = &user.LoginResponse{
            User: nil,
            BaseResp: &user.BaseResponse{
                Code: 100,
                Msg:  "login fail",
            },
        }
    }

    out, err := proto.Marshal(req)
    if err == nil {
        c.Data(200, "application/x-protobuf", out)
    }
})

四、客户端测试代码

NSDate *startDate = [NSDate date];
LoginRequest *req = [[LoginRequest alloc] init];
req.username = @"admin";
req.password = @"123456";
[self postUrl:@"http://127.0.0.1:8080/login" dataBody:[req data] Completetion:^(id result, NSError *error) {
    if (!error && [result isKindOfClass:[NSData class]]) {
        NSData *data = (NSData *)result;
        NSError *pError;
        LoginResponse *resp = [[LoginResponse alloc] initWithData:data error:&pError];
        if (!pError) {
            NSDate *endDate1 = [NSDate date];
            _infolabel.text = [NSString stringWithFormat:@"数据大小 ： %.3f KB, 请求耗时：%f",[data length]/1000.0,[endDate1 timeIntervalSinceDate:startDate]];
            _textView.text = resp.description;
        }
    }
}];
