Question

我有一项接受多个参数并安排工作的服务。有些参数可能太长，因此我决定使用POST请求。服务定义如下：

<WebInvoke(Method:="POST", UriTemplate:="scheduleJob?JobDateTime={JobDateTime}&JobName={JobName}&TestCases={TestCases}&IDs={IDs}&UserName={UserName}", ResponseFormat:=WebMessageFormat.Json)>

Function ScheduleJob(ByVal JobDateTime As String, ByVal JobName As String, ByVal TestCases As String, ByVal IDs As String, ByVal UserName As String) As String

jQuery调用是：

            $.ajax({
                type: "POST",
                crossDomain: true,
                url: svcUrl + "jobDateTime={" + jobDateTime + "}jobName={" + jobName + "}TestCases={" + TestCases + "}IDs={" + IDs+ "} + UserName={" + UserName + "}",                        
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                processData: true,
                success: function (data) {
                    alert("success...");
                },
                error: function (xhr) {
                    alert(xhr.responseText);
                }
            });

在通过fiddler检查时，我发现IE浏览器发送的请求会在标头中发送POST，但是当我使用Mozilla或Chrome时，OPTIONS标头似乎会附加到请求中。

我阅读了一些帖子并对我的asp.net进行了一些修改：

 If HttpContext.Current.Request.HttpMethod = "OPTIONS" Then 
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "POST,GET")
            HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "172800")
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*")
End If

但似乎没有任何效果。如果我在fiddler中只用“POST”来模拟相同的请求，那么事情似乎很酷。唯一的问题是如何摆脱“选项”？

我获得了OPTIONS请求的405响应代码。标题是：

OPTIONS http://localhost:60403/TaskScheduler.svc/scheduleJob?jobDateTime={12/31/2014%2016:25}jobName={}TestCases={format,localeFormat,_toFormattedString,}Ids={0,}%20+%20UserName={abcd} HTTP/1.1

非常感谢任何其他建议。
