[英]Sending data to handler in .NET via Ajax. XML Parsing Error: no root element found
[英]XML Parsing Error: no root element found in ASP.NET Core 5.0 Ajax
我正在我的項目中工作,並進行注冊。 我正在嘗試使用 Ajax 處理我的數據以注冊 Controller 到操作寄存器。 並在 java 腳本調試器中得到這個錯誤:
XML Parsing Error: no root element found
Location: https://localhost:44396/Auth/Register
Line Number 1, Column 1
所以,這是我的消息來源:
JS:
let fD = new FormData();
fD.append('Email', email);
fD.append('Name', name);
fD.append('Password', pass);
$('#loading').addClass('processing');
$.ajax({
type: 'POST',
url: '@Url.Action("Register")',
data: fD,
processData: false,
contentType: false,
success: function(res, status, xhr) {
$('#loading').removeClass('processing');
let result = xhr.getResponseHeader("registration_result")
if (result === "ok") {
createMessage('zmdi-check','You have successfully registered in our site');
Timer();
}
else if (result === "failed") {
createMessage('zmdi-close','This email address already exists</br>Please choose a unique one');
form.email.classList.add('error');
}
else // "error"
createMessage('zmdi-close','An error occurred while registering</br>Please try again')
}
})
行動:
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Register(RegisterViewModel model)
{
var user = new User();
var valid = ValidateUser(model);
if (!valid)
Response.Headers.Add("registration_result", new StringValues("error"));
else if (FindUser(model.Email))
Response.Headers.Add("registration_result", new StringValues("failed"));
else
{
user = _catalog.AddUserOrDefault(new UserRegistrationDto
{
Email = model.Email,
Name = model.Name,
Password = model.Password
});
Response.Headers.Add("registration_result", new StringValues("ok"));
}
if (user != null)
{
await _signInManager.SignInAsync(user, false);
}
return Ok(model);
}
和形式:
<form method="POST" name="signUp" class="form register-form" id="register-form" onsubmit="return false;">
<label class="label-input" for="">
<i class="zmdi far fa-user icon-modify"></i>
<input class="auth-input" type="text" placeholder="Name" name="name" id="name">
</label>
<label class="label-input" for="">
<i class="zmdi far fa-envelope icon-modify"></i>
<input class="auth-input" type="email" placeholder="Email" name="email" id="email">
</label>
<label class="label-input" for="">
<i class="zmdi fas fa-lock icon-modify"></i>
<input class="auth-input" type="password" placeholder="Password" name="pass" id="pass">
</label>
<button class="btn btn-secondary" id="signup-button">sign up</button>
</form>
在調試中,我正在輸入
$('#loading').addClass('processing');
並且無法進入Action。
以防萬一我的 model:
public class RegisterViewModel
{
public string Email { get; set; }
public string Name { get; set; }
public string Password { get; set; }
}
我希望有任何幫助:)
您在后端使用了ValidateAntiForgeryToken
屬性,因此您必須在發送請求時添加RequestVerificationToken
header。
這是您可以遵循的工作演示:
看法:
<form method="POST" name="signUp" class="form register-form" id="register-form" onsubmit="return false;">
<label class="label-input" for="">
<i class="zmdi far fa-user icon-modify"></i>
<input class="auth-input" type="text" placeholder="Name" name="name" id="name">
</label>
<label class="label-input" for="">
<i class="zmdi far fa-envelope icon-modify"></i>
<input class="auth-input" type="email" placeholder="Email" name="email" id="email">
</label>
<label class="label-input" for="">
<i class="zmdi fas fa-lock icon-modify"></i>
<input class="auth-input" type="password" placeholder="Password" name="pass" id="pass">
</label>
<button class="btn btn-secondary" id="signup-button" onclick="Test()">sign up</button>
</form>
<div id="loading"></div>
@section Scripts
{
<script>
function Test() {
var email = $("#email").val();
var name = $("#name").val();
var pass = $("#pass").val();
let fD = new FormData();
fD.append('Email', email);
fD.append('Name', name);
fD.append('Password', pass);
$('#loading').addClass('processing');
$.ajax({
type: 'POST',
url: '@Url.Action("Register")',
data: fD,
//be sure add this...
headers: {
RequestVerificationToken: $('input:hidden[name="__RequestVerificationToken"]').val()
},
processData: false,
contentType: false,
success: function(res, status, xhr) {
$('#loading').removeClass('processing');
let result = xhr.getResponseHeader("registration_result")
if (result === "ok") {
createMessage('zmdi-check','You have successfully registered in our site');
Timer();
}
else if (result === "failed") {
createMessage('zmdi-close','This email address already exists</br>Please choose a unique one');
form.email.classList.add('error');
}
else // "error"
createMessage('zmdi-close','An error occurred while registering</br>Please try again')
}
})
}
</script>
