Golang 协程Cover异常防止闪退

协程报错闪退

协程如果不cover异常会出现闪退问题,但是在大批量创建各种协程每次都需要cover会非常难处理,golang 异常处理我不是很熟悉,简单写了一个,不知道是否靠谱

common

package logger

import (
    "fmt"
    "reflect"
    "runtime"
    "strings"
)

//创建安全的协程
func CreateSafeGo(call func(), errCall func(err interface{})) {
    go func() {
        defer SafeGoRecover(errCall)
        call()
    }()
}

func SafeGoRecover(errCall func(err interface{})) {
    if err := recover(); err != nil {
        Error("recover error: %v", err)
        if errCall != nil {
            errCall(err)
        }
    }
}

func getCaller() string {
    src := "No Caller"
    _, file, lineno, ok := runtime.Caller(2)
    var strim = "src/"
    //fix # 不是每个前面都有src的,所以可以获取当前
    if ok {
        src = strings.Replace(fmt.Sprintf("%s:%d", stringTrim(file, strim), lineno), "%2e", ".", -1)
    }
    return src
}

//TODO Params
//反射实现参数恢复
func SafeGoWithParams(call interface{}, errCall func(err interface{}), params ...interface{}) {
    go func() {
        defer SafeGoRecover(errCall)
        funcValue := reflect.ValueOf(call)
        var paramsList []reflect.Value
        for _, v := range params {
            paramsList = append(paramsList, reflect.ValueOf(v))
        }
        funcValue.Call(paramsList)
    }()
}

test

package logger

import (
    "fmt"
    "testing"
    "time"
)

func TestCreateSafeGo(t *testing.T) {
    CreateSafeGo(func() {
        panic("1231")
    }, func(err interface{}) {
        Error("asdasd")

    })
    time.Sleep(time.Second)
}

func TestSafeGoRecover(t *testing.T) {
    go func() {
        defer SafeGoRecover(func(err interface{}) {
            Error("asdasd")
        })
        panic("1231")
    }()
    time.Sleep(time.Second)
}

func TestCreateSafeGoWithParams(t *testing.T) {
    SafeGoWithParams(func(aa int) {
        fmt.Println(aa)
    }, func(err interface{}) {

    }, 123)
    time.Sleep(time.Second)
}
