[![Benchmarks: Jul 18, 2020 at 10:46am (UTC)](https://iris-go.com/images/benchmarks.svg)](https://github.com/kataras/server-benchmarks)

## 📖 开始学习 Iris

```sh
# 安装Iris：https://www.iris-go.com/#ebookDonateForm
$ go get github.com/kataras/iris/v12@latest
# 假设main.go文件中已存在以下代码
$ cat main.go
```

```go
package main

import "github.com/kataras/iris/v12"

func main() {
	app := iris.New()

	booksAPI := app.Party("/books")
	{
		booksAPI.Use(iris.Compression)

		// GET: http://localhost:8080/books
		booksAPI.Get("/", list)
		// POST: http://localhost:8080/books
		booksAPI.Post("/", create)
	}

	app.Listen(":8080")
}

// Book example.
type Book struct {
	Title string `json:"title"`
}

func list(ctx iris.Context) {
	books := []Book{
		{"Mastering Concurrency in Go"},
		{"Go Design Patterns"},
		{"Black Hat Go"},
	}

	ctx.JSON(books)
	// 提示: 在服务器优先级和客户端请求中进行响应协商，
	// 以此来代替 ctx.JSON:
	// ctx.Negotiation().JSON().MsgPack().Protobuf()
	// ctx.Negotiate(books)
}

func create(ctx iris.Context) {
	var b Book
	err := ctx.ReadJSON(&b)
	// 提示: 使用 ctx.ReadBody(&b) 代替，来绑定所有类型的入参
	if err != nil {
		ctx.StopWithProblem(iris.StatusBadRequest, iris.NewProblem().
			Title("Book creation failure").DetailErr(err))
		// 提示: 如果仅有纯文本（plain text）错误响应，
        // 可使用 ctx.StopWithError(code, err) 
		return
	}

	println("Received Book: " + b.Title)

	ctx.StatusCode(iris.StatusCreated)
}
```

同样地，在**MVC**中 :

```go
import "github.com/kataras/iris/v12/mvc"
```

```go
m := mvc.New(booksAPI)
m.Handle(new(BookController))
```

```go
type BookController struct {
	/* dependencies */
}

// GET: http://localhost:8080/books
func (c *BookController) Get() []Book {
	return []Book{
		{"Mastering Concurrency in Go"},
		{"Go Design Patterns"},
		{"Black Hat Go"},
	}
}

// POST: http://localhost:8080/books
func (c *BookController) Post(b Book) int {
	println("Received Book: " + b.Title)

	return iris.StatusCreated
}
```

**启动** 您的 Iris web 服务:

```sh
$ go run main.go
> Now listening on: http://localhost:8080
> Application started. Press CTRL+C to shut down.
```

Books **列表查询** :

```sh
$ curl --header 'Accept-Encoding:gzip' http://localhost:8080/books

[
  {
    "title": "Mastering Concurrency in Go"
  },
  {
    "title": "Go Design Patterns"
  },
  {
    "title": "Black Hat Go"
  }
]
```

**创建** 新的Book:

```sh
$ curl -i -X POST \
--header 'Content-Encoding:gzip' \
--header 'Content-Type:application/json' \
--data "{\"title\":\"Writing An Interpreter In Go\"}" \
http://localhost:8080/books

> HTTP/1.1 201 Created
```

这是**错误**响应所展示的样子：

```sh
$ curl -X POST --data "{\"title\" \"not valid one\"}" \
http://localhost:8080/books

> HTTP/1.1 400 Bad Request

{
  "status": 400,
  "title": "Book creation failure"
  "detail": "invalid character '\"' after object key",
}
```

</details>
