基本介绍
GoFrame
的Server
默认自带的OpenAPI
接口文档UI是redoc
开源组件,该组件不支持页面Try It Out
功能的。很多同学都在问,能否使用SwaggerUI
页面来展示OpenAPI
接口文档?有的企业内部并不支持连接外网的部分资源,那么能否将内部的接口文档UI替换为内部可访问的资源呢?
了解OpenAPI
这个东东的小伙伴应该都知道,OpenAPI
只是通用的接口定义规范,而展示的接口文档UI是可以随便替换的,并且这种UI界面以及平台还特别多!使用GoFrame Server
来切换接口文档UI页面,或者将接口文档对接到第三方接口文档平台 - 非常简单! 非常简单!详见示例:gf/example/httpserver/swagger-set-template/main.go at master · gogf/gf (github.com)
使用示例
咱们通过代码来展示一下,如何快速地将接口文档UI切换为SwaggerUI
。SwaggerUI

为了演示简便,这里将所有的代码都写到一个代码文件中,没有使用配置或页面文件。代码如下:
Code Block | ||
---|---|---|
| ||
package main import ( "context" "fmt" "github.com/gogf/gf/v2/frame/g" "github.com/gogf/gf/v2/net/ghttp" ) const ( swaggerUIPageContent = ` <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta name="description" content="SwaggerUI"/> <title>SwaggerUI</title> <link rel="stylesheet" href="https://unpkg.com/swagger-ui-dist@latest/swagger-ui.css" /> </head> <body> <div id="swagger-ui"></div> <script src="https://unpkg.com/swagger-ui-dist@latest/swagger-ui-bundle.js" crossorigin></script> <script> window.onload = () => { window.ui = SwaggerUIBundle({ url: '/api.json', dom_id: '#swagger-ui', }); }; </script> </body> </html> ` ) type HelloReq struct { g.Meta `path:"/hello" method:"get"` Name string `v:"required" dc:"Your name"` } type HelloRes struct { Reply string `dc:"Reply content"` } type Hello struct{} func (Hello) Say(ctx context.Context, req *HelloReq) (res *HelloRes, err error) { g.Log().Debugf(ctx, `receive say: %+v`, req) res = &HelloRes{ Reply: fmt.Sprintf(`Hi %s`, req.Name), } return } func main() { s := g.Server() s.Use(ghttp.MiddlewareHandlerResponse) s.Group("/", func(group *ghttp.RouterGroup) { group.GET("/swagger", func(r *ghttp.Request) { r.Response.Write(swaggerUIPageContent) }) group.Bind( new(Hello), ) }) s.SetOpenApiPath("/api.json") s.SetPort(8199) s.Run() } |
我们这里只定义了一个Hello
的接口。可以看到,我们通过一个接口来展示SwaggerUI
的HTML
页面,并且将OpenAPI
的接口文件路径定义为/api.json
,没有启用Server
自带的UI页面。执行后,终端输出:

页面展示如下:
开发者自定义其他的接口文档UI类似如此。

需要注释掉config.yaml文件中的 swaggerPath: "/swagger" 这一行,否则界面不会改变 |
