+  - **Methods** - `Bind`, `BindJSON`, `BindXML`, `BindQuery`, `BindYAML`, `BindHeader`
   - **Behavior** - These methods use `MustBindWith` under the hood. If there is a binding error, the request is aborted with `c.AbortWithError(400, err).SetType(ErrorTypeBind)`. This sets the response status code to 400 and the `Content-Type` header is set to `text/plain; charset=utf-8`. Note that if you try to set the response code after this, it will result in a warning `[GIN-debug] [WARNING] Headers were already written. Wanted to override status code 400 with 422`. If you wish to have greater control over the behavior, consider using the `ShouldBind` equivalent method.

-# How to build one effective middleware?
-
-## Consitituent part
-
-The middleware has two parts:
-
-  - part one is what is executed once, when you initialize your middleware. That's where you set up all the global objects, logicals etc. Everything that happens one per application lifetime.
-
-  - part two is what executes on every request. For example, a database middleware you simply inject your "global" database object into the context. Once it's inside the context, you can retrieve it from within other middlewares and your handler function.
-
-```go
-func funcName(params string) gin.HandlerFunc {
-    // <---
-    // This is part one
-    // --->
-    // The follow code is an example
-    if err := check(params); err != nil {
-        panic(err)
-    }
-
-    return func(c *gin.Context) {
-        // <---
-        // This is part two
-        // --->
-        // The follow code is an example
-        c.Set("TestVar", params)
-        c.Next()    
-    }
-}
-```
-
-## Execution process
-
-Firstly, we have the follow example code:
-
-```go
-func main() {
-	router := gin.Default()
-
-	router.Use(globalMiddleware())
-
-	router.GET("/rest/n/api/*some", mid1(), mid2(), handler)
-
-	router.Run()
-}
-
-func globalMiddleware() gin.HandlerFunc {
-	fmt.Println("globalMiddleware...1")
-
-	return func(c *gin.Context) {
-		fmt.Println("globalMiddleware...2")
-		c.Next()
-		fmt.Println("globalMiddleware...3")
-	}
-}
-
-func handler(c *gin.Context) {
-	fmt.Println("exec handler.")
-}
-
-func mid1() gin.HandlerFunc {
-	fmt.Println("mid1...1")
-
-	return func(c *gin.Context) {
-
-		fmt.Println("mid1...2")
-		c.Next()
-		fmt.Println("mid1...3")
-	}
-}
-
-func mid2() gin.HandlerFunc {
-	fmt.Println("mid2...1")
-
-	return func(c *gin.Context) {
-		fmt.Println("mid2...2")
-		c.Next()
-		fmt.Println("mid2...3")
-	}
-}
-```
-
-According to [Consitituent part](#consitituent-part) said, when we run the gin process, **part one** will execute firstly and will print the follow information:
-
-```go
-globalMiddleware...1
-mid1...1
-mid2...1
-```
-
-And init order are:
-
-```go
-globalMiddleware...1
-    |
-    v
-mid1...1
-    |
-    v
-mid2...1
-```
-
-When we curl one request `curl -v localhost:8080/rest/n/api/some`, **part two** will execute their middleware and output the following information:
-
-```go
-globalMiddleware...2
-mid1...2
-mid2...2
-exec handler.
-mid2...3
-mid1...3
-globalMiddleware...3
-```
-
-In other words, run order are:
-
-```go
-globalMiddleware...2
-    |
-    v
-mid1...2
-    |
-    v
-mid2...2
-    |
-    v
-exec handler.
-    |
-    v
-mid2...3
-    |
-    v
-mid1...3
-    |
-    v
-globalMiddleware...3

-The [New Relic Go Agent](https://github.com/newrelic/go-agent) provides a nice middleware for the stdlib handler signature. 
-The following is an adaptation of that middleware for Gin.

-```golang
-const (

-	NewRelicTxnKey = "NewRelicTxnKey"
-)
-
-// NewRelicMonitoring is a middleware that starts a newrelic transaction, stores it in the context, then calls the next handler
-func NewRelicMonitoring(app newrelic.Application) gin.HandlerFunc {

-		ctx.Next()

-## Struct level validations
-
-Validations can also be registered at the `struct` level when field level validations
-don't make much sense. This can also be used to solve cross-field validation elegantly.
-Additionally, it can be combined with tag validations. Struct Level validations run after
-the structs tag validations.
-
-### Example requests
-
-```shell
-# Validation errors are generated for struct tags as well as at the struct level
-$ curl -s -X POST http://localhost:8085/user \
-	-H 'content-type: application/json' \
-	-d '{}' | jq
-{
-  "error": "Key: 'User.Email' Error:Field validation for 'Email' failed on the 'required' tag\nKey: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag\nKey: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag",
-  "message": "User validation failed!"
-}
-
-# Validation fails at the struct level because neither first name nor last name are present
-$ curl -s -X POST http://localhost:8085/user \
-    -H 'content-type: application/json' \
-	-d '{"email": "george@vandaley.com"}' | jq
-{
-  "error": "Key: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag\nKey: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag",
-  "message": "User validation failed!"
-}
-
-# No validation errors when either first name or last name is present
-$ curl -X POST http://localhost:8085/user \
-    -H 'content-type: application/json' \
-	-d '{"fname": "George", "email": "george@vandaley.com"}'
-{"message":"User validation successful."}
-
-$ curl -X POST http://localhost:8085/user \
-    -H 'content-type: application/json' \
-	-d '{"lname": "Contanza", "email": "george@vandaley.com"}'
-{"message":"User validation successful."}
-
-$ curl -X POST http://localhost:8085/user \
