Gin 学习笔记01-数据返回

1、返回 string 和 json

• c.String()
• c.JSON()

package mainimport ("github.com/gin-gonic/gin""net/http"
)func getJSON(c *gin.Context) {//c.String(http.StatusOK, "小明")//c.JSON(http.StatusOK, gin.H{"name": "小明", "age": 18})//type User struct {//	Name string//	Age  int//}// 自定义返回的字段名成//type User struct {//	Name string `json:"name"`//	Age  int    `json:"age"`//}// 如果不想让某个字段返回可以使用 “-”type User struct {Name     string `json:"name"`Age      int    `json:"age"`Password string `json:"-"`}user := User{"小明", 18, "123123"}c.JSON(http.StatusOK, user)
}func main() {router := gin.Default()router.GET("/getJSON", getJSON)router.Run(":9000")
}

2、返回 xml 和 ymal

• c.XML()
• c.YAML()

package mainimport ("github.com/gin-gonic/gin""net/http"
)func getXML(c *gin.Context) {c.XML(http.StatusOK, gin.H{"name": "小明", "age": 18})
}func getYAML(c *gin.Context) {c.YAML(http.StatusOK, gin.H{"name": "小明", "age": 18})
}func main() {router := gin.Default()router.GET("/getXML", getXML)router.GET("/getYAML", getYAML)router.Run(":9000")
}

3、返回html

• router.LoadHTMLGlob()
• router.StaticFS()
• router.StaticFs()

package mainimport ("github.com/gin-gonic/gin""net/http"
)func getHtml(c *gin.Context) {c.HTML(http.StatusOK, "index.html", gin.H{"name": "小明"})
}func main() {router := gin.Default()// 全局加载router.LoadHTMLGlob("template/*")// 加载目录router.StaticFS("/static", http.Dir("static/static"))// 加载静态文件router.StaticFile("/login.jpg", "static/login.jpg")router.GET("/getHtml", getHtml)router.Run(":9000")
}

4、重定向

• c.Redirect()

package mainimport ("github.com/gin-gonic/gin""net/http"
)func direct(c *gin.Context) {c.Redirect(http.StatusMovedPermanently, "http://www.baidu.com")
}func main() {router := gin.Default()router.GET("/redirect", direct)router.Run(":9000")
}
