jsonp调用通过把要输出的数据放到Data["jsonp"]中，然后调用ServeJSONP()进行渲染，会设置content-type为application/javascript，然后同时把数据进行JSON序列化，然后根据请求的callback参数设置jsonp输出。 ~~~ |-- admin | |--controllers | `-- user.go ~~~ ~~~ package admin import ( "github.com/astaxie/beego" ) type UserController struct { beego.Controller } type stu struct { Name string Age int Addr string } func (this *UserController) Index() { user := &stu{"Murphy", 28, "帝都"} this.Data["jsonp"] = user this.ServeJSONP() this.TplName = "admin/user/index.html" } ~~~ ~~~ |-- views | |--admin | |--user | `-- index.html ~~~ ~~~ <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head> <body> <h3>{{.jsonp}}</h3> </body> </html> ~~~ 浏览器访问： http://127.0.0.1:8080/admin/user/index 浏览器输出： ~~~ <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head> <body> <h3>{Murphy 28 帝都}</h3> </body> </html> ~~~
