|
||
|
||
A package of validators and sanitizers for strings, structs and collections. Based on [validator.js](https://github.com/chriso/validator.js).
|
||
|
||
#### Installation
|
||
Make sure that Go is installed on your computer.
|
||
Type the following command in your terminal:
|
||
|
||
go get github.com/asaskevich/govalidator
|
||
|
||
or you can get specified release of the package with `gopkg.in`:
|
||
|
||
go get gopkg.in/asaskevich/govalidator.v10
|
||
|
||
After it the package is ready to use.
|
||
|
||
|
||
#### Import package in your project
|
||
Add following line in your `*.go` file:
|
||
```go
|
||
import "github.com/asaskevich/govalidator"
|
||
```
|
||
If you are unhappy to use long `govalidator`, you can do something like this:
|
||
```go
|
||
import (
|
||
valid "github.com/asaskevich/govalidator"
|
||
)
|
||
```
|
||
|
||
#### Activate behavior to require all fields have a validation tag by default
|
||
`SetFieldsRequiredByDefault` causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). A good place to activate this is a package init function or the main() function.
|
||
|
||
`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors.
|
||
|
||
```go
|
||
import "github.com/asaskevich/govalidator"
|
||
|
||
func init() {
|
||
govalidator.SetFieldsRequiredByDefault(true)
|
||
}
|
||
```
|
||
|
||
Here's some code to explain it:
|
||
```go
|
||
// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
|
||
type exampleStruct struct {
|
||
Name string ``
|
||
Email string `valid:"email"`
|
||
}
|
||
|
||
// this, however, will only fail when Email is empty or an invalid email address:
|
||
type exampleStruct2 struct {
|
||
Name string `valid:"-"`
|
||
Email string `valid:"email"`
|
||
}
|
||
|
||
// lastly, this will only fail when Email is an invalid email address but not when it's empty:
|
||
type exampleStruct2 struct {
|
||
Name string `valid:"-"`
|
||
Email string `valid:"email,optional"`
|
||
}
|
||
```
|
||
|
||
#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123))
|
||
##### Custom validator function signature
|
||
A context was added as the second parameter, for structs this is the object being validated – this makes dependent validation possible.
|
||
```go
|
||
import "github.com/asaskevich/govalidator"
|
||
|
||
// old signature
|
||
func(i interface{}) bool
|
||
|
||
// new signature
|
||
func(i interface{}, o interface{}) bool
|
||
```
|
||
|
||
##### Adding a custom validator
|
||
This was changed to prevent data races when accessing custom validators.
|
||
```go
|
||
import "github.com/asaskevich/govalidator"
|
||
|
||
// before
|
||
govalidator.CustomTypeTagMap["customByteArrayValidator"] = func(i interface{}, o interface{}) bool {
|
||
// ...
|
||
}
|
||
|
||
// after
|
||
govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, o interface{}) bool {
|
||
// ...
|
||
})
|
||
```

#### Examples
|
||
###### IsURL
|
||
```go
|
||
println(govalidator.IsURL(`http://user@pass:domain.com/path/page`))
|
||
```
|
||
###### IsType
|
||
```go
|
||
println(govalidator.IsType("Bob", "string"))
|
||
println(govalidator.IsType(1, "int"))
|
||
i := 1
|
||
println(govalidator.IsType(&i, "*int"))
|
||
```
|
||
|
||
IsType can be used through the tag `type` which is essential for map validation:
|
||
```go
|
||
type User struct {
|
||
Name string `valid:"type(string)"`
|
||
Age int `valid:"type(int)"`
|
||
Meta interface{} `valid:"type(string)"`
|
||
}
|
||
result, err := govalidator.ValidateStruct(User{"Bob", 20, "meta"})
|
||
if err != nil {
|
||
println("error: " + err.Error())
|
||
}
|
||
println(result)
|
||
```
|
||
###### ToString
|
||
```go
|
||
type User struct {
|
||
FirstName string
|
||
LastName string
|
||
}
|
||
|
||
str := govalidator.ToString(&User{"John", "Juan"})
|
||
println(str)
|
||
```
|
||
###### Each, Map, Filter, Count for slices
|
||
Each iterates over the slice/array and calls Iterator for every item
|
||
```go
|
||
data := []interface{}{1, 2, 3, 4, 5}
|
||
var fn govalidator.Iterator = func(value interface{}, index int) {
|
||
println(value.(int))
|
||
}
|
||
govalidator.Each(data, fn)
|
||
```
|
||
```go
|
||
data := []interface{}{1, 2, 3, 4, 5}
|
||
var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} {
|
||
return value.(int) * 3
|
||
}
|
||
_ = govalidator.Map(data, fn) // result = []interface{}{1, 6, 9, 12, 15}
|
||
```
|
||
```go
|
||
data := []interface{}{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
|
||
var fn govalidator.ConditionIterator = func(value interface{}, index int) bool {
|
||
return value.(int)%2 == 0
|
||
}
|
||
_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10}
|
||
_ = govalidator.Count(data, fn) // result = 5
|
||
```
|
||
###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2)
|
||
If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this:
|
||
```go
|
||
govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
|
||
return str == "duck"
|
||
})
|
||
```
|
||
For completely custom validators (interface-based), see below.
|
||
|
||
Here is a list of available validators for struct fields (validator - used function):

|
||

|
||
```
|
||
Validators with parameters
|
||
|
||
```go
|
||
"range(min|max)": Range,
|
||
"length(min|max)": ByteLength,
|
||
"runelength(min|max)": RuneLength,

|
||
```
|
||
Validators with parameters for any type
|
||
|
||
```go
|
||
"type(type)": IsType,
|
||
```
|
||
|
||
And here is small example of usage:
|
||
```go
|
||
type Post struct {
|
||
Title string `valid:"alphanum,required"`
|
||
Message string `valid:"duck,ascii"`
|
||
Message2 string `valid:"animal(dog)"`
|
||
AuthorIP string `valid:"ipv4"`
|
||
Date string `valid:"-"`
|
||
}
|
||
post := &Post{
|
||
Title: "My Example Post",
|
||
Message: "duck",
|
||
Message2: "dog",
|
||
AuthorIP: "123.234.54.3",
|
||
}
|
||
|
||
// Add your own struct validation tags
|
||
govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
|
||
return str == "duck"
|
||
})
|
||
|
||
// Add your own struct validation tags with parameter
|
||
govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool {
|
||
species := params[0]
|
||
return str == species
|
||
})
|
||
govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$")
|
||
|
||
result, err := govalidator.ValidateStruct(post)
|
||
if err != nil {
|
||
println("error: " + err.Error())
|
||
}
|
||
println(result)
|
||
```
|
||
###### ValidateMap [#2](https://github.com/asaskevich/govalidator/pull/338)
|
||
If you want to validate maps, you can use the map to be validated and a validation map that contain the same tags used in ValidateStruct, both maps have to be in the form `map[string]interface{}`
|
||
|
||
So here is small example of usage:
|
||
```go
|
||
var mapTemplate = map[string]interface{}{
|
||
"name":"required,alpha",
|
||
"family":"required,alpha",
|
||
"email":"required,email",
|
||
"cell-phone":"numeric",
|
||
"address":map[string]interface{}{
|
||
"line1":"required,alphanum",
|
||
"line2":"alphanum",
|
||
"postal-code":"numeric",
|
||
},
|
||
}
|
||
|
||
var inputMap = map[string]interface{}{
|
||
"name":"Bob",
|
||
"family":"Smith",
|
||
"email":"foo@bar.baz",
|
||
"address":map[string]interface{}{
|
||
"line1":"",
|
||
"line2":"",
|
||
"postal-code":"",
|
||
},
|
||
}
|
||
|
||
result, err := govalidator.ValidateMap(inputMap, mapTemplate)
|
||
if err != nil {
|
||
println("error: " + err.Error())
|
||
}
|
||
println(result)
|
||
```
|
||
|
||
###### WhiteList
|
||
```go
|
||
// Remove all characters from string ignoring characters between "a" and "z"
|
||
println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
|
||
```
|
||
|
||
###### Custom validation functions
|
||
Custom validation using your own domain specific validators is also available - here's an example of how to use it:
|
||
```go
|
||
import "github.com/asaskevich/govalidator"
|
||
|
||
type CustomByteArray [6]byte // custom types are supported and can be validated
|
||
|
||
type StructWithCustomByteArray struct {
|
||
ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence
|
||
Email string `valid:"email"`
|
||
CustomMinLength int `valid:"-"`
|
||
}
|
||
|
||
govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, context interface{}) bool {
|
||
switch v := context.(type) { // you can type switch on the context interface being validated
|
||
case StructWithCustomByteArray:
|
||
// you can check and validate against some other field in the context,
|
||
// return early or not validate against the context at all – your choice
|
||
case SomeOtherType:
|
||
// ...
|
||
default:
|
||
// expecting some other type? Throw/panic here or continue
|
||
}
|
||
|
||
switch v := i.(type) { // type switch on the struct field being validated
|
||
case CustomByteArray:
|
||
for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes
|
||
if e != 0 {
|
||
return true
|
||
}
|
||
}
|
||
}
|
||
return false
|
||
})
|
||
govalidator.CustomTypeTagMap.Set("customMinLengthValidator", func(i interface{}, context interface{}) bool {
|
||
switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation
|
||
case StructWithCustomByteArray:
|
||
return len(v.ID) >= v.CustomMinLength
|
||
}
|
||
return false
|
||
})
|
||
```
|
||
|
||
###### Loop over Error()
|
||
By default .Error() returns all errors in a single String. To access each error you can do this:
|
||
```go
|
||
if err != nil {
|
||
errs := err.(govalidator.Errors).Errors()
|
||
for _, e := range errs {
|
||
fmt.Println(e.Error())
|
||
}
|
||
}
|
||
```
|
||
|
||
###### Custom error messages
|
||
Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it:
|
||
```go
|
||
type Ticket struct {
|
||
Id int64 `json:"id"`
|
||
FirstName string `json:"firstname" valid:"required~First name is blank"`
|
||
}
|
||
```
|
||

#### Support
|
||
If you do have a contribution to the package, feel free to create a Pull Request or an Issue.
|
||
|
||
#### What to contribute
|
||
If you don't know what to do, there are some features and functions that need to be done
|
||
|
||
- [ ] Refactor code
|
||
- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check
|
||
- [ ] Create actual list of contributors and projects that currently using this package
|
||
- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues)
|
||
- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions)
|
||
- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new
|
||
- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc
|
||
- [x] Implement [validation by maps](https://github.com/asaskevich/govalidator/issues/224)
|
||
- [ ] Implement fuzzing testing
|
||
- [ ] Implement some struct/map/array utilities
|
||
- [ ] Implement map/array validation
|
||
- [ ] Implement benchmarking
|
||
- [ ] Implement batch of examples
|
||
- [ ] Look at forks for new features and fixes
|
||
|
||
#### Advice
|
||
Feel free to create what you want, but keep in mind when you implement new features:
|
||
- Code must be clear and readable, names of variables/constants clearly describes what they are doing
|
||
- Public functions must be documented and described in source file and added to README.md to the list of available functions
|
||
- There are must be unit-tests for any new functions and improvements
