一、
1.安装
go get -u github.com/gin-gonic/gin
2.例子
package main import "github.com/gin-gonic/gin" func main() { r := gin.Default() r.GET("/ping", func(c *gin.Context) { c.JSON(200, gin.H{ "message": "pong", }) }) r.Run() }
3.测试
4.结合 vue和Bootstrap
main.go
package main import ( "net/http" "github.com/gin-gonic/gin" ) func main() { r := gin.Default() r.LoadHTMLGlob("view/*") r.GET("/", func(c *gin.Context) { c.HTML(http.StatusOK, "index.html", gin.H{}) }) r.Run() }
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" > </head> <body> <div id="vm" class="container"> <div class="d-flex justify-content-center p-5"> <input v-model="message"/> </div> <div class="d-flex justify-content-center"> <h1>${message}</h1> </div> </div> <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" ></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js" ></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" ></script> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> <script> var vm = new Vue({ // 由于双花括号和go模板冲突，把vue双花改成${message}形式 delimiters: ['${', '}'], el: '#vm', data: { message: null } }) </script> </body> </html>
二、
1.请求方式及请求路径
func main() { //使用默认中间件创建一个gin路由器 r := gin.Default() //get请求方式：参数1地址，参数2函数 r.GET("/", getting) //启动默认端口8080 r.Run() } func getting(c *gin.Context) { // c.JSON(200, "Hello") }
2.参数
（1）路径传参
127.0.0.1:8080/tom
func main() { r := gin.Default() //get请求方式：参数1地址，参数2函数 r.GET("/:name", getting) r.Run() } func getting(c *gin.Context) { // name := c.Param("name") c.String(200, "Hello %s", name) }
（2）get
func main() { r := gin.Default() r.GET("/", getting) r.Run() } func getting(c *gin.Context) { //设置默认值，如果客户端为传递str1，则默认赋值为def str1 := c.DefaultQuery("str1", "def") str2 := c.Query("str2") // 是 c.Request.URL.Query().Get("str2") 的简写 c.String(200, "Hello %s ", str1) c.String(200, "Hello %s", str2) }
(3)表单
func main() { r := gin.Default() r.POST("/", posting) r.Run() } func posting(c *gin.Context) { name := c.PostForm("name") c.String(200, "Hello %s ", name) age := c.DefaultPostForm("age", "18") // 此方法可以设置默认值 c.String(200, "Hello %s", age) }
