||
[![codecov](https://codecov.io/gh/elvinchan/echoswagger/branch/master/graph/badge.svg)](https://codecov.io/gh/elvinchan/echoswagger)
|
||
|
||
## 特性
|
||
- 不依赖任何SwaggerUI的HTML/CSS文件
|
||
- 与Echo高度整合,低侵入式设计
|
||
- 利用强类型语言和链式编程的优势,简单易用
|
||
- 及时的垃圾回收,低内存占用
|
||
|
||
## 安装
|
||
```
|
||
go get github.com/elvinchan/echoswagger
|
||
```
|
||
|
||
## 示例
|
||
```go
|
||
package main
|
||
|
||
import (
|
||
"net/http"
|
||
|
||
"github.com/elvinchan/echoswagger"
|
||
"github.com/labstack/echo"
|
||
)
|
||
|
||
func main() {
|
||
// ApiRoot with Echo instance
|
||
r := echoswagger.New(echo.New(), "/v1", "doc/", nil)
|
||
|
||
// Routes with parameters & responses
|
||
r.POST("/", createUser).
|
||
AddParamBody(User{}, "body", "User input struct", true).
|
||
AddResponse(http.StatusCreated, "successful", nil, nil)
|
||
|
||
// Start server
|
||
r.Echo().Logger.Fatal(r.Echo().Start(":1323"))
|
||
}
|
||
|
||
type User struct {
|
||
Name string
|
||
}
|
||
|
||
// Handler
|
||
func createUser(c echo.Context) error {
|
||
return c.JSON(http.StatusCreated, nil)
|
||
}
|
||
|
||
```
|
||
|
||
## 用法
|
||
#### 用`New()`创建`ApiRoot`,此方法是对`echo.New()`方法的封装
|
||
```
|
||
r := echoswagger.New(echo.New(), "/v1", "doc/", nil)
|
||
```
|
||
你可以用这个`ApiRoot`来:
|
||
- 设置Security定义, 请求/响应Content-Type,UI选项,等。
|
||
```
|
||
r.AddSecurityAPIKey("JWT", "JWT Token", echoswagger.SecurityInHeader).
|
||
SetRequestContentType("application/x-www-form-urlencoded", "multipart/form-data").
|
||
SetUI(UISetting{HideTop: true})
|
||
```
|
||
- 获取`echo.Echo`实例。
|
||
```
|
||
r.Echo()
|
||
```
|
||
- 在默认组中注册一个GET、POST、PUT、DELETE、OPTIONS、HEAD或PATCH路由,这些是对Echo的注册路由方法的封装。
|
||
此方法返回一个`Api`实例。
|
||
```
|
||
r.GET("/:id", handler)
|
||
```
|
||
- 以及: ↓
|
||
|
||
#### 用`Group()`创建`ApiGroup`,此方法是对`echo.Group()`方法的封装
|
||
```
|
||
g := r.Group("Users", "/users")
|
||
```
|
||
你可以用这个`ApiGroup`来:
|
||
- 设置描述,等。
|
||
```
|
||
g.SetDescription("The desc of group")
|
||
```
|
||
- 为此组中的所有路由设置Security。
|
||
```
|
||
g.SetSecurity("JWT")
|
||
```
|
||
- 获取`echo.Group`实例。
|
||
```
|
||
g.EchoGroup()
|
||
```
|
||
- 以及: ↓
|
||
|
||
#### 在`ApiGroup`中注册一个新的路由
|
||
Echoswagger支持GET、POST、PUT、DELETE、OPTIONS、HEAD或PATCH方法,这些是对Echo的注册路由方法的封装。
|
||
```
|
||
a := g.GET("/:id", handler)
|
||
```
|
||
你可以使用此`Api`实例来:
|
||
- 使用以下方法添加参数:
|
||
```
|
||
AddParamPath(p interface{}, name, desc string)
|
||
|
||
AddParamPathNested(p interface{})
|
||
|
||
AddParamQuery(p interface{}, name, desc string, required bool)
|
||
|
||
AddParamQueryNested(p interface{})
|
||
|
||
AddParamForm(p interface{}, name, desc string, required bool)
|
||
|
||
AddParamFormNested(p interface{})
|
||
|
||
AddParamHeader(p interface{}, name, desc string, required bool)
|
||
|
||
AddParamHeaderNested(p interface{})
|
||
|
||
AddParamBody(p interface{}, name, desc string, required bool)
|
||
|
||
AddParamFile(name, desc string, required bool)
|
||
```
|
||
|
||
后缀带有`Nested`的方法把参数`p`的字段看做多个参数,所以它必须是结构体类型的。
|
||
|
||
例:
|
||
```
|
||
type SearchInput struct {
|
||
Q string `query:"q" swagger:"desc("Keywords"),required"`
|
||
SkipCount int `query:"skipCount"`
|
||
}
|
||
a.AddParamQueryNested(SearchInput{})
|
||
```
|
||
等价于:
|
||
```
|
||
a.AddParamQuery("", "q", "", true).
|
||
AddParamQuery(0, "skipCount", "", false)
|
||
```
|
||
- 添加响应。
|
||
```
|
||
a.AddResponse(http.StatusOK, "response desc", body{}, nil)
|
||
```
|
||
- 设置Security,请求/响应的Content-Type,概要,描述,等。
|
||
```
|
||
a.SetSecurity("JWT").
|
||
SetResponseContentType("application/xml").
|
||
SetSummary("The summary of API").
|
||
SetDescription("The desc of API")
|
||
```
|
||
- 获取`echo.Route`实例。
|
||
```
|
||
a.Route()
|
||
```
|
||
|
||
#### 使用swagger标签,你可以在`AddParam...`方法中设置更多信息
|
||
例:
|
||
```
|
||
type User struct {
|
||
Age int `swagger:"min(0),max(99)"`
|
||
Gender string `swagger:"enum(male|female|other),required"`
|
||
Money []float64 `swagger:"default(0),readOnly"`
|
||
}
|
||
a.AddParamBody(&User{}, "Body", "", true)
|
||
```
|
||
此定义等价于:
|
||
```
|
||
{
|
||
"definitions": {
|
||
"User": {
|
||
"type": "object",
|
||
"properties": {
|
||
"Age": {
|
||
"type": "integer",
|
||
"format": "int32",
|
||
"minimum": 0,
|
||
"maximum": 99
|
||
},
|
||
"Gender": {
|
||
"type": "string",
|
||
"enum": [
|
||
"male",
|
||
"female",
|
||
"other"
|
||
],
|
||
"format": "string"
|
||
},
|
||
"Money": {
|
||
"type": "array",
|
||
"items": {
|
||
"type": "number",
|
||
"default": 0,
|
||
"format": "double"
|
||
},
|
||
"readOnly": true
|
||
}
|
||
},
|
||
"required": [
|
||
"Gender"
|
||
]
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
**支持的`swagger`标签:**
|
||
|
||
Tag | Type | Description
|
||
---|:---:|---
|
||
collect | `string` | 如果类型是数组,确定其格式。可能的值有:<ul><li>`csv` - 逗号分隔的值 `foo,bar`。<li>`ssv` - 空格分隔的值 `foo bar`。<li>`tsv` - tab分隔的值 `foo\tbar`。<li>`pipes` - pipe分隔的值 `foo\|bar`。</ul>默认值是 `csv`。
|
||
desc | `string` | 描述。
|
||
maximum | `number` | -
|
||
minimum | `number` | -
|
||
maxLength | `integer` | -
|
||
minLength | `integer` | -
|
||
allowEmpty | `boolean` | 设置传递空值参数的功能。 这仅对`query`或`formData`参数有效,并允许你发送仅具有名称或空值的参数。默认值为“false”。
|
||
required | `boolean` | 确定此参数是否必需。如果参数是`in`“path”,则此属性默认为“true”。否则,可以设置此属性,其默认值为“false”。
|
||
readOnly | `boolean` | 仅与Schema`"properties"`定义相关。将属性声明为“只读”。这意味着它可以作为响应的一部分发送,但绝不能作为请求的一部分发送。标记为“readOnly”的属性为“true”,不应位于已定义模式的“required”列表中。默认值为“false”。
|
||
enum | [*] | 枚举值,多个值应以“\|”分隔。
|
||
default | * | 默认值,该类型与字段的类型相同。
