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 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.
