## 安装
```
go get -u github.com/gorilla/schema
```
## 实例
### simple demo
```
import "github.com/gorilla/schema"
type Person struct {
Name string `schema:"name"` // 支持schema标签
Phone string `schema:"-"` // - 表示此字段不进行绑定
}
// 请求参数映射
values := map[string][]string{
"Name": {"Alex"},
"Phone": {"13399999999"},
}
person := new(Person)
decoder := schema.NewDecoder()
decoder.Decode(person, values)
```
### 结合 http
```
type Person struct {
Name string `schema:"name,required"` // custom name, must be supplied
Phone string `schema:"phone"` // custom name
Admin bool `schema:"-"` // this field is never set
}
var Decoder = schema.NewDecoder()
func MyHandler2(w http.ResponseWriter, r *http.Request) {
r.ParseForm()
var person Person
e := Decoder.Decode(&person, r.PostForm)
if e != nil {
w.Write([]byte(e.Error()))
}
fmt.Printf("%+v\n", person)
// {Name: Phone:123 Admin:false}
w.Write([]byte("success"))
}
```
```
curl -X POST -d "name=cpj&phone=123" http://localhost:9090 -> success
curl -X POST -d "phone=123" http://localhost:9090 -> name is empty
```
