Go Language Form Verification

1. Required Fields

if len(r.Form["username"][0])==0{//为空的处理}

2. Digital Check

//the first method  Getint,err:=strconv  (R  ( "age" ) if  err!= nil  {//Digital conversion error, then it may not be the number } //then you can determine the size range of the number  if  getint >100  { It's too big. }//second method "regular match"  if  m, _: = regexp< Span class= "hljs-variable". Matchstring  ( "^[0-9]+$" , R  (),!m {return  false } 

3. The Chinese check "Go" is RE2, all characters are UTF-8 encoded. 】

//对于中文我们目前有两种方式来验证，可以使用 unicode 包提供的//func Is(rangeTab *RangeTable, r rune) bool 来验证，也可以使//用正则方式来验证，这里使用最简单的正则方式if m, _ := regexp.MatchString("^\\p{Han}+$", r.Form.Get("realname")); !m {    returnfalse}

4. English check

ifregexp.MatchString("^[a-zA-Z]+$",       r.Form.Get("engname")); !m {    false}

5. e-mail address

if m, _ := regexp.MatchString(`^([\w\.\_]{2,10})@(\w{1,}).([a-z]{2,4})$`, r.Form.Get("email")); !m {    fmt.Println("no")}else{    fmt.Println("yes")}

6. Mobile phone number

if m, _ := regexp.MatchString(`^(1[3|4|5|8][0-9]\d{4,8})$`, r.Form.Get("mobile")); !m {    returnfalse}

7. Drop-down menu

<select name="Fruit"><option value="Apple">apple</option><option value="Pear">pear</option><option value="Banane">banane</option></select>slice:=[]string{"Apple","Pear","Banane"} for_, V: = Range Slice {ifv = = R.form.get ("Fruit") {returntrue}}returnfalse

8. Radio button

type="radio" name="gender" value="1"type="radio" name="gender" value="2">女slice:=[]int{1,2}for_, v := range slice {    if v == r.Form.Get("gender") {        returntrue    }}returnfalse

9. check box

<input Type="checkbox"Name="Interest" value="Football"> Football <input Type="checkbox"Name="Interest" value="Basketball"> Basketball <input Type="checkbox"Name="Interest" value="Tennis"> Tennis slice:=[]string{"Football","Basketball","Tennis"}a:=slice_diff (r.form["Interest"],slice)ifA = = nil{returntrue}returnfalse

10. Date and Time

//Go里面提供了一个timetime.Date(2009time1023000time.UTC)fmt.Printf("Go launched at %s\n", t.Local())//获取time之后我们就可以进行很多时间函数的操作。具体的判断就根据自己的需求调整。

11. Identification number

//verify 15-bit ID, 15-bit is all digits  if  m, _: = RegExp. Matchstring ( "^ (\d{15}) $ ' , R.form.get (" Usercard " ));!m {return  false }//validates the 18-bit ID, the 18-bit first 17 digits are digits, the last one is the check digit, which can be either a number or a character X.  if  m, _: = RegExp. Matchstring ( "^ (\d{17}) ([0-9]| X) $ ' , R.form.get ( "Usercard" );!m {return  false }
