        <input type="reset" value="Clear">

<p id="error" style="color: darkred"></p>
</form>
</html>

我有以下路线代码

public Result signUp() {
    //Gets from GET method
    String fName = form().bindFromRequest().get("fName");
    String lName = form().bindFromRequest().get("lName");
    String email = form().bindFromRequest().get("email");
    String password = form().bindFromRequest().get("password");
    String username = form().bindFromRequest().get("username");

    //Creating new instance
    User user = new User(username, fName, lName, email, password);
    User r = hash.put(username, user);
    //Adding user to array and check its added
    if (hash.put(username, user) != null) {
        return ok(login.render("Successfully Signup"));
    } else {
        return ok(("Sign up failed"));
    }
}

我的问题是，当我尝试访问http://localhost:9000/时，我得到：

POST     /signupUser                controllers.UserController.signUp

但是当我将signUp签名更改为UserController中的signUp（String id）时，它工作正常

为方法signUp播放太多参数:(）play.api.mvc.Call
