NetworkError：Firefox中的REST服务中不允许405方法

Question

我在jQuery AJAX POST中调用了REST服务。最初我收到网络错误：405方法不允许。但是当我在Global.asax文件中的Application_BeginRequest（）中添加以下代码时，错误消失并且不调用服务。它仍会在Firefox中显示选项 http请求。为什么即使添加代码也会发生这种情况。

Application_BeginRequest（）代码

protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
{
HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type,X-PINGOTHER Accept, x-requested-with");
HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
HttpContext.Current.Response.End();
}
}

界面

[ServiceContract]
public interface IService1{
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "/TokenInsertion", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
string UserdetailInsertion(UserInputParameters userInput);
}<br/>

服务

 public string UserdetailInsertion(UserInputParameters userInput)
{
try
{
command = database.GetStoredProcCommand(DataTemplate.UspUserdetailInsertion);
database.AddInParameter(command, DataTemplate.AssociateRefId, DbType.String, userInput.AssociateRefId);
database.AddInParameter(command, DataTemplate.CpecialLoginId, DbType.String, userInput.CpecialLoginId);
database.AddInParameter(command, DataTemplate.PartnerId, DbType.String, userInput.PartnerId);
database.AddInParameter(command, DataTemplate.FirstName, DbType.String, userInput.FirstName);
database.AddInParameter(command, DataTemplate.LastName,DbType.String,userInput.LastName);
database.AddInParameter(command, DataTemplate.CreatedDate, DbType.String, userInput.CreatedDate);
database.ExecuteNonQuery(command);
return "0";
}
catch(Exception err)
{   throw err; 
}
}

jQuery Ajax

var postCall = function () {
var input = {
AssociateRefId: "412", CpecialLoginId: "sdfa", PartnerId: "dfs", FirstName: "fdsf", LastName: "dfsr", Comments: "dsad", CreatedDate: "2013-02-15 15:54:10.130"
};
alert(JSON.stringify(input));
$.ajax({
type: "POST",
url: "http://localhost:45970/Service1.svc/TokenInsertion",
data: JSON.stringify(input),
contentType: "application/json",
dataType: "json",
success: function (response) {
alert(response);
},
error: function (xhr, status, error) {
alert(error);
alert(status);
}
});
}<br/>

任何建议都会有很大帮助。

编辑：Firefox中的Http请求
