c# - 使用 Angular 登录 WinApi C#

Question

我在发送邮件时收到此错误。你知道我必须做什么吗？登录 WinApi C#

XMLHttpRequest cannot load http://localhost:56305/Token. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:64757' is therefore not allowed access. The response had HTTP status code 400.

我的代码

//linki
    $scope.addLink = "http://localhost:56305/Token";

    $scope.addData = function () {
        if ($scope.password != "" && $scope.email) {
            $http({
                method: "POST",
                url: $scope.addLink,
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
                headers: {'X-Requested-With' :'XMLHttpRequest'},
                data: { grant_type: 'password', username: $scope.email, Password: $scope.password }
            }).then(function mySucces(response) {
                $scope.stateHideError = true;
                $scope.stateHideSuccess = false;
                Authorization.go('carInsurance');
            }, function myError(response) {
                $scope.stateHideError = false;
                $scope.stateHideSuccess = true;
                $scope.error = "Wystąpił błąd - Problem z wysłaniem parametrów";
            });
        }
        else {
            $scope.stateHideError = false;
            $scope.stateHideSuccess = true;
            $scope.error = "Wystąpił błąd - nie podałeś wszystkich wymaganych wartości.";
        }
    };

PtrScn

我想发送这样的内容

我将其添加到 WinApi C#

    <httpProtocol>
        <customHeaders>
          <add name="Access-Control-Allow-Origin" value="*"/>
        </customHeaders>
    </httpProtocol>

现在我遇到了这个错误

XMLHttpRequest cannot load http://localhost:56305/Token. Response for preflight has invalid HTTP status code 400
