向Web API控制器发送请求时出现404错误 [英] 404 error when send request to web api controller
问题描述
我正在创建一个ASP.NET MVC网站,正如标题所说,我正在尝试使用jquery向Web Api控制器发送POST请求,但始终收到404错误.疯狂的是,在.NET Framework 4.5中,完全相同的东西起作用,但是在.NET Framework 4.6.2中,实际上没有.我已经在Google中找到很多线程来解释可能会出错的地方,但是这些都不起作用.所以,这是我的代码:
Web Api类:
I am creating a ASP.NET MVC web site and as the title say i am trying to send a POST request to Web Api controller with jquery, but am always receiving a 404 error. The crazy thing is that in the .NET framework 4.5 the exact the same thing worked, but in the .NET framework 4.6.2 it really doesn''t. I ''ve found a lot of threads in google explaining what it might go wrong, but none of these worked. So, here is my code now:
The Web Api Class:
[Authorize]
public class CartController : ApiController
{
private ApplicationDbContext _context;
public CartController()
{
_context = new ApplicationDbContext();
}
[HttpPost]
public IHttpActionResult AddToCart(string productId)
{
if (!ModelState.IsValid || !ItemIsValid(productId))
return BadRequest();
var newCartItem = new ShoppingCartItem
{
ProductId = productId,
UserId = User.Identity.GetUserId()
};
_context.ShoppingCartItems.Add(newCartItem);
_context.SaveChanges();
return Ok();
}
private bool ItemIsValid(string productId)
{
return Enumerable.Any(_context.Products, contextproduct => contextproduct.Id.ToString() == productId && contextproduct.NumberAvailable > 0);
}
}
我的jQuery代码:
My jQuery code:
$(".buy-button").click(function() {
if (@User.Identity.IsAuthenticated.ToString().ToLower() === true) {
$.ajax({
url: "/api/cart",
method: "POST",
data: $(this).next().val()
}).done(function() {
alert("Product succesfully added to cart!");
});
} else {
window.location.href = "@Url.Action("Login", "Account")";
}
});
Global.asax代码:
The Global.asax code:
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
如果有人可以帮助我,那将是很棒的.我已经花了6多个小时来解决这个错误,但我仍然找不到我做错了什么.
我尝试过的事情:
1)一些线程说Global.asax中调用"的顺序很重要,因此我更改了"
It would be great if someone could help me. I have spent over 6 hours on this bug, and i can''t still find out what i am doing wrong.
What I have tried:
1) Some threads said that the order of the "calls" in the Global.asax matters, so i changed the position of ''
RouteConfig.RegisterRoutes(RouteTable.Routes);
"
的位置
在任何可能的地方.
2)在我的Web Api操作([Route("api/Cart/AddToCart")])中添加了路线属性,根据经验我知道这是多余的……并相应地更改了我的jQuery代码.
3)我没有添加属性,而是将Routes直接添加到Web Api Config.
4)我也尝试直接用邮递员打电话给Api(我当然删除了Authorize属性).
这些都不起作用.
''
in every possible place.
2) Added Route Attributes in my Web Api action([Route("api/Cart/AddToCart")]) which i know from experience that is redundant ... and changed my jQuery code accordingly.
3) Instead of adding attributes, i added to Routes directly to the Web Api Config.
4) I also tried to call the Api with postman directly(i removed the Authorize attribute of course).
None of these worked.

(.buy-button").click(function(){ 如果(@ User.Identity.IsAuthenticated.ToString().ToLower()=== true){
(".buy-button").click(function() { if (@User.Identity.IsAuthenticated.ToString().ToLower() === true) {
.ajax({ 网址:"/api/cart", 方法:"POST", 数据:
.ajax({ url: "/api/cart", method: "POST", data:
(this).next().val() }).done(function(){ alert(产品成功添加到购物车!"); }); } 别的 { window.location.href ="@ Url.Action("登录,"帐户)"; } });
(this).next().val() }).done(function() { alert("Product succesfully added to cart!"); }); } else { window.location.href = "@Url.Action("Login", "Account")"; } });
