golang如何使用正则表达式

    package main

    import (
        "fmt"
        "regexp"
        //"strings"
    )

    type User struct{
        Id int
    }
    func main() {

        r, _ := regexp.Compile("^[\u4E00-\u9FA5]*$")
        fmt.Println(r.MatchString("我"))
        //true
    }

正则表达式以^开头,$结束!

推荐一款非常好用轻便的正则框架
main.go

package main

import (
    "github.com/fwhezfwhez/superChecker"
    "fmt"
    "log"
)
type User struct {
    UserName string `superChecker:"userName" json:"userName"`
    Password string `superChecker:"password"`
    Phone string `superChecker:"mobilephone|telephone"`
    Text string `superChecker:"length,chineseOnly,notNull"`
}
func main(){
    user := User{
        "",
        "a1dfdasfsdf",
        "12578854875",
        "中",
    }
    checker :=superChecker.GetChecker()
    checker.AddRegex("passWoRd","^[\\s\\S]{6,}$")
    checker.AddRegex("length","^[\\s\\S]{0,20}$")
    checker.AddRegex("chineseOnly","^[\u4E00-\u9FA5]*$")
    result,msg,err :=checker.SuperCheck(user)
    if err!=nil {
        log.Println(err)
    }
    fmt.Println("匹配结果:",result,"信息:",msg)

    checker.AddDefaultRegex("chineseOnly","^[\u4E00-\u9FA5]*$")

    checker.ListDefault()

    checker.ListRegexBuilder()

    checker.ListAll()
}

以后处理前端的数据,就不用单独get,并各种ifCheckxxxxx
使用这种注解模式来应对前端请求,User是响应的VO模型,前端可能会发送username password,phone等数据
给vo加上superChecker注解,check一步达成!
