我不确定这对我意味着什么。我在过去的一两天里一直在挑选它。我还有其他与“GET”一起使用的功能，但这是流程链中的第一个“POST”命中。有谁知道出了什么问题？

错误输出：

称呼：

//when stringified, it looks correct.  No real obvious holes.
//the variables in data are strings, and are recognized correctly in the request payload of the file.

var settings = {
    url: "webservices/FormServices.svc/SaveXml",
    type: "POST",
    contentType: "text/xml",
    data: JSON.stringify({ auth: auth, server: server, datasource: datasource, FileId:FileId, XML:xml }),
    success: success,
    error: error
};
console.log("Settings", settings);
return $.ajax(settings);

服务：

//this is of a class i made with a [ServiceContract]

[OperationContract]
    [WebInvoke(Method = "POST",
        ResponseFormat = WebMessageFormat.Json)]
    string SaveXml(string auth, string server, string datasource, string FileId, string XML);

服务：

public string SaveXml(string auth, string server, string datasource, string FileId, string XML)
    {
    string response = "-1";
    return response;
    }

捆绑：

<system.serviceModel>
<services>
  <service name="test.webservices.FormServices" behaviorConfiguration="debug">
    <endpoint address="" behaviorConfiguration="test.webservices.FormServicesAspNetAjaxBehavior"
      binding="webHttpBinding" contract="test.webservices.IFormServices"/>

我认为这是因为您正在尝试使用 json 作为数据并指定“text/xml”的 contentType 而不是 json 的 dataType。

你应该试试这个：

var settings = {
    url: "webservices/FormServices.svc/SaveXml",
    type: "POST",
    dataType: "json",
    contentType: "application/json",
    data: JSON.stringify({ auth: auth, server: server, datasource: datasource, FileId:FileId, XML:xml }),
    success: success,
    error: error
};
