大家好， 我遇到问题是我的jquery代码：

Hi All, I am stuck in a problem here is my jquery code:

$(document).ready(function () { $('#btnSubmit').click(function () { var companyId = $("#companyname").val(); var startDate = $("#startdate").val(); var endDate = $("#endate").val(); var codeType = $("#typecode option:selected").text(); var record = "companyid=" + companyId + "&startDate=" + startDate + "&enddate=" + endDate + "&type=" + codeType; var tempurl = 'localhost:49987/api/prospectbounce?' + record; $.ajax({ url: 'localhost:49987/api/prospectbounce?' + record, type: 'GET', async: false, dataType: 'json', success: function (data) { debugger var html = '<table border="1" width="100%">'; html += ' <th align="left"><b>Email Address</b></th>' html += ' <th align="left"><b>Synchronization Key</b></th>' html += '</tr>' $.each(data, function (index, value) { html += '<tr>'; html += '<td align="left">' + value.Email + '</td>'; html += '<td align="left">' + value.SynchronizationKey + '</td>'; html += '</tr>'; }); html += '</table>'; $('#recordShow').html(html); }, error: function (xhr, status, error) { alert(error); }, beforeSend: setHeader }); }); }); function setHeader(xhr) { xhr.setRequestHeader('X-ProspectAppApiKey', '8EJBD8BI:f9a2ac88-6a76-48cf-8357-3f54bb830703'); }

及以下是我的网络API代码

and below is my web API code

protected override System.Threading.Tasks.Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken) { // Write your Authentication code here IEnumerable<string> monsterApiKeyHeaderValues = null; if (request.Headers.TryGetValues("X-ProspectAppApiKey", out monsterApiKeyHeaderValues)) { string[] apiKeyHeaderValue = monsterApiKeyHeaderValues.First().Split(':'); if (apiKeyHeaderValue.Length == 2) { var appID = apiKeyHeaderValue[0]; var AppKey = apiKeyHeaderValue[1]; String StrValidationToken = ProspectAccountInfo.IsValidToken(appID, "CRMValidationToken"); Boolean IsValidToken = false; if (!string.IsNullOrEmpty(StrValidationToken)) { //check token if (StrValidationToken.ToString().ToLower() == AppKey.ToString().ToLower()) { IsValidToken = true; } } if (IsValidToken) { var userNameClaim = new Claim(ClaimTypes.Name, appID); var identity = new ClaimsIdentity(new[] { userNameClaim }, "ProspectAppApiKey"); var principal = new ClaimsPrincipal(identity); Thread.CurrentPrincipal = principal; if (System.Web.HttpContext.Current != null) { System.Web.HttpContext.Current.User = principal; } } else { return requestCancel(request, cancellationToken, InvalidToken); } } else { return requestCancel(request, cancellationToken, MissingToken); } } else { // Web request cancel reason APP key missing all parameters return requestCancel(request, cancellationToken, MissingToken); } return base.SendAsync(request, cancellationToken); }

我的问题是当我从跨域发送请求时，我无法处理请求但是使用IE它工作正常。 请帮助我。 感谢&问候 Mohd Wasif
