Question

我正在努力通过WCF Web服务将Web表单连接到SSIS。我的问题始于交叉引用服务的问题，现在它已成为服务中出现错误的问题。

这是我的代码：

//Service
[ServiceContract]
public interface IExtractionService
{
    [OperationContract]
    [WebInvoke(Method = "POST",
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "/SubmitExtraction")]
    string runExtraction(string start, string end, string packageName);
}


public string runExtraction(string start, string end, string packageName)
    {
        //code to run SSIS package
    }

//Javascript
$("#btnSubmit").click(function () {
    var startDateTime = ($("#from").data + " 00:00:00");
    var endDateTime = ($("#to").data + " 23:59:59");
    var ExtractionData = {
        "start": startDateTime,
        "end": endDateTime,
        "packageName": $("#packageName").data
    };
    $.ajax({
        type: "POST",
        url: "ExtractionService.svc/runExtraction",
        data: JSON.stringify(ExtractionData),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        processData: true,
        success: function (data, status) {
            alert("success..." + data);
        },
        error: function () {
            alert("Failed");
        }
    })
})

//Global.asax.cs
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("Access-Control-Allow-Methods", "GET, POST");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
        HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000" );
        HttpContext.Current.Response.End();
    }
}

//web.config
<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding name="BasicHttpBinding_IExtractionService" />
    </basicHttpBinding>
  </bindings>
  <standardEndpoints>
    <webHttpEndpoint>
      <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true"></standardEndpoint>
    </webHttpEndpoint>
  </standardEndpoints>
  <client>
    <endpoint address="http://localhost:49313/ExtractionService.svc"
    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IExtractionService"
    contract="ExtractionServices.IExtractionService"        name="BasicHttpBinding_IExtractionService" />
  </client>
  <behaviors>
    <serviceBehaviors>
      <behavior name="">
        <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="false" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
    multipleSiteBindingsEnabled="true" />
</system.serviceModel>

这应该是你所需要的。如果还有别的，我可以说出来。我觉得它很小。我一点一点地把所有这些放在一起，我知道它看起来很不稳定，但我觉得它的大部分都处于正常工作状态。任何帮助表示赞赏。

在我访问url的ajax调用中，我按如下方式输入方法名称：

$.ajax({
    type: "POST",
    url: "ExtractionService.svc/runExtraction",
    data: JSON.stringify(ExtractionData),
    contentType: "application/json; charset=utf-8",
    dataType: "json",

该服务指定了一个uri，直到第二眼之后才点击我的脑袋，当我更改url以匹配uri而不是方法名称时如下：

$.ajax({
    type: "POST",
    url: "ExtractionService.svc/SubmitExtraction",
    data: JSON.stringify(ExtractionData),
    contentType: "application/json; charset=utf-8",
    dataType: "json",

WCF AJAX无法推断架构。请求/响应正文被包装
