基本介绍
GoFrame
的Server
默认自带的OpenAPI
接口文档UI是[redoc](https://redocly.com/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!
使用示例
咱们通过代码来展示一下,如果快速地将接口文档UI切换为SwaggerUI
。SwaggerUI

- https://github.com/swagger-api/swagger-ui/blob/master/docs/usage/installation.md
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:
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.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:

开发者自定义其他的接口文档UI类似如此。
