# Gin Helper

Note: gindump utilities are courtesy of [this repo](https://github.com/tpkeeper/gin-dump) and have only been updated/modified here because of dependency issues.
<!--TODO: document non gindump deps-->

* Gin middleware/handler to dump header/body of request and response .

* Very helpful for debugging your applications.

* More beautiful output than httputil.DumpXXX()

## Content-type support / todo

* [x] application/json
* [x] application/x-www-form-urlencoded
* [ ] text/xml
* [ ] application/xml
* [ ] text/plain

## Usage

All:

```go
func main() {
    router := gin.Default()

    //use Dump() default will print on stdout
    router.Use(gindump.Dump())

    //or use DumpWithOptions() with more options
    router.Use(gindump.DumpWithOptions(true, true, false, true, false, func(dumpStr string) {
	    fmt.Println(dumpStr)
    }))

    router.Post("/",myHandler)

    ...

    router.Run()
}
```

Group:

```go
func main() {
    router := gin.Default()

    dumpGroup := router.Group("/group")

    //use Dump() default will print on stdout
    dumpGroup.Use(gindump.Dump())

    //or use DumpWithOptions() with more options
    dumpGroup.Use(gindump.DumpWithOptions(true, true, false, true, false, func(dumpStr string) {
	    fmt.Println(dumpStr)
    }))

    dumpGroup.Post("/",myHandler)

    ...

    router.Run()
}

```

EndPoint:

```go
func main() {
    router := gin.Default()

    //use Dump() default will print on stdout
    router.Post("/",gindump.Dump(),myHandler)

    //or use DumpWithOptions() with more options
    router.Post("/",gindump.DumpWithOptions(true, true, false, true, false, func(dumpStr string) {
	    fmt.Println(dumpStr)
    }),myHandler)

    ...

    router.Run()
}
```
