英文:
How to get and AJAX response using Golang with Gin Routing
问题
这是我的 Golang 代码（注意在 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")}
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);}});
我需要一种方法将字符串作为响应从 Golang 返回给 AJAX 请求。
英文:
Here is my code of Golang (Notice the registerNewUser in the POST ("/register") handler:
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:
$.ajax({url: "/register",method: "POST",data: {firstname:Firstname, lastname:Lastname, username:Username, email:Email, password:Password, country:Country},beforeSend:function(){$("#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

fmt和log分别打印到os.Stdout和os.Stderr。你需要对web请求做出响应。
Gin将一个*gin.Context传递给你的处理程序来实现这个目的。
https://pkg.go.dev/github.com/gin-gonic/gin#readme-quick-start展示了一个非常简单的通过上下文返回数据的示例。在https://pkg.go.dev/github.com/gin-gonic/gin#readme-api-examples中还有很多其他很棒的示例。
在查看了一些示例以理解通常的用法后，“上下文是gin最重要的部分”，所以请仔细阅读文档。
一旦你觉得对快速入门有所了解，可以看一下gin的Context.String。你可以将其替换为示例中的c.JSON调用。
英文:
fmt and log print to os.Stdout and os.Stderr respectively. You need to respond to the web request.
Gin passes a *gin.Context to your handler for this purpose.
https://pkg.go.dev/github.com/gin-gonic/gin#readme-quick-start shows a very small example of returning data through the context. There are tons of other great examples in https://pkg.go.dev/github.com/gin-gonic/gin#readme-api-examples.
"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.
Once you feel like you have your head wrapped around the quickstart, take a look at gin's Context.String . You can substitute that for the c.JSON call in the example.
