快速开始

这里给出一个简单的server端,client端代码,更多的样例可以参考 example/v2

server

package main

import (
    "context"
    "github.com/gojuukaze/YTask/v2"
    "os"
    "os/signal"
    "syscall"
)

// 定义两个任务,任务参数、返回值支持所有能被序列化为json的类型

func add(a int, b int) int {
    return a + b
}

type User struct {
    Id   int
    Name string
}

func appendUser(user User, ids []int, names []string) []User {
    var r = make([]User, 0)
    r = append(r, user)
    for i := range ids {
        r = append(r, User{ids[i], names[i]})
    }
    return r
}

func main() {
    // RedisBroker最后一个参数是连接池大小, Server端无需设置
    broker := ytask.Broker.NewRedisBroker("127.0.0.1", "6379", "", 0, 0)

    // RedisBackend最后一个参数是连接池大小,对于server端 如果<=0 会使用默认值,
    // 默认值是 min(10, numWorkers)
    backend := ytask.Backend.NewRedisBackend("127.0.0.1", "6379", "", 0, 0)

    ser := ytask.Server.NewServer(
        ytask.Config.Broker(&broker),
        ytask.Config.Backend(&backend),
        ytask.Config.Debug(true),
        ytask.Config.StatusExpires(60*5),
        ytask.Config.ResultExpires(60*5),
    )

    // 注册任务
    ser.Add("group1", "add", add)
    ser.Add("group1", "append_user", appendUser)

    // 运行server,并发数3
    ser.Run("group1", 3)

    quit := make(chan os.Signal, 1)

    signal.Notify(quit, syscall.SIGINT, syscall.SIGTERM)
    <-quit
    ser.Shutdown(context.Background())

}

client

package main

import (
    "fmt"
    "github.com/gojuukaze/YTask/v2"
    "github.com/gojuukaze/YTask/v2/server"
    "time"
)

type User struct {
    Id   int
    Name string
}

var client server.Client

func main() {
    // 对于client端你需要设置连接池大小
    broker := ytask.Broker.NewRedisBroker("127.0.0.1", "6379", "", 0, 5)

    // 对于client端,如果连接池<=0,poolSize会默认为10
    backend := ytask.Backend.NewRedisBackend("127.0.0.1", "6379", "", 0, 5)

    ser := ytask.Server.NewServer(
        ytask.Config.Broker(&broker),
        ytask.Config.Backend(&backend),
        ytask.Config.Debug(true),
        ytask.Config.StatusExpires(60*5),
        ytask.Config.ResultExpires(60*5),
    )

    client = ser.GetClient()

    // 提交任务
    taskId, _ := client.Send("group1", "add", 123, 44)
    // 获取结果
    result, _ := client.GetResult(taskId, 2*time.Second, 300*time.Millisecond)

    if result.IsSuccess() {
        // 有多种方法获取返回值,具体可以参考: https://doc.ikaze.cn/YTask/client.html#id4
        sum, _ := result.GetInt64(0)
        // or
        var sum2 int
        result.Get(0, &sum2)

        fmt.Println("add(123,44) =", int(sum))
    }

    // 提交结构体,slice等
    taskId, _ = client.Send("group1", "append_user", User{1, "aa"}, []int{322, 11}, []string{"bb", "cc"})
    result, _ = client.GetResult(taskId, 2*time.Second, 300*time.Millisecond)
    var users []User
    result.Get(0, &users)
    fmt.Println(users)

}
