[英]How to get and AJAX response using Golang with Gin Routing
Here is my code of Golang (Notice the registerNewUser in the POST ("/register") handler:这是我的 Golang 代码(注意 POST ("/register") 处理程序中的 registerNewUser:
func main(){
router := gin.Default()
router.LoadHTMLFiles("../login.html", "../recoverPassword.html")
router.Static("/css", "../css")
router.Static("/img", "../img")
router.Static("/js", "../js")
router.GET("/", loadMainPage)
router.POST("/register", registerNewUser)
router.Run("localhost:8080")
}
func registerNewUser(c *gin.Context) {
fmt.Print("Nonas")
log.Print("Sisas")
}
Now, here is my code of javascript:现在,这是我的 javascript 代码:
$.ajax({
url: "/register",
method: "POST",
data: {firstname:Firstname, lastname:Lastname, username:Username, email:Email, password:Password, country:Country},
beforeSend:function(){
$("#submit_register_form_btn").attr('disabled', true);
$("#submit_register_form_btn").val('Conectando...');
},
success:function(response) {
$('#submit_register_form_btn').removeAttr('disabled');
alert(response);
}
});
I need a way to return a string as response from Golang to the AJAX petition我需要一种方法将字符串作为响应从 Golang 返回到 AJAX 请求
fmt
and log
print to os.Stdout
and os.Stderr
respectively. fmt
和log
分别打印到os.Stdout
和os.Stderr
。 You need to respond to the web request.您需要响应网络请求。
Gin passes a *gin.Context
to your handler for this purpose. *gin.Context
,Gin 将*gin.Context
传递给您的处理程序。
https://pkg.go.dev/github.com/gin-gonic/gin#readme-quick-start shows a very small example of returning data through the context. https://pkg.go.dev/github.com/gin-gonic/gin#readme-quick-start展示了一个通过上下文返回数据的小例子。 There are tons of other great examples inhttps://pkg.go.dev/github.com/gin-gonic/gin#readme-api-examples .
https://pkg.go.dev/github.com/gin-gonic/gin#readme-api-examples 中有很多其他很棒的例子。
"Context is the most important part of gin," so read the documentation thoroughly after reviewing a few examples to wrap your head around what usage generally looks like. “上下文是 gin 中最重要的部分”,因此在查看了几个示例之后,请仔细阅读文档,以了解通常的用法。
Once you feel like you have your head wrapped around the quickstart, take a look at gin's Context.String .一旦您觉得自己已经完全了解快速入门,请查看 gin 的Context.String 。 You can substitute that for the
c.JSON
call in the example.您可以将其替换为示例中的
c.JSON
调用。
