jquery - 在 jquery ajax 调用 wcf 服务上从 http 移动到 https 时出错

Question

我有一个 wcf 服务，托管在 .NET 3.5 Web 应用程序内的 IIS 6.0 中，并且它通过 http 工作正常，但是当我尝试实现 https/ssl 时，我收到 415 错误，并显示以下错误消息。我对请求和响应都使用 json。

“无法处理消息，因为内容类型“application/json”不是预期类型“application/soap+xml；charset=utf-8”。”

下面是我的客户端 jquery.ajax 调用、服务契约(Contract)和 web.config。我在这里缺少什么？

Jquery.ajax 调用:

    $.ajax({
    type: "POST",
        url: "DataShare.svc/GetProgramsByEventType",
        data: '{"eventTypeIds": "' + eventTypeId + '"}',
        contentType: "application/json",
        dataType: "json",
        async: false, //async needs to be false to work with programs dropdown
        success: function (data, status) {
            var programs = data.GetProgramsByEventTypeResult;
            var html = "";
            for (var i = 0; i < programs.length; i++) {
                html += "<li><a href='#'>" + programs[i].m_ProgramLongDesc + "<span class='value'>" + programs[i].m_ProgramID + "</span></a></li>"
            }
            $("#ddlProgramItems").html(html);
        },
        error: function (request, status, error) {
            alert("Error - Status: " + request.status + "\nStatusText: " + request.statusText + "\nResponseText: " + request.responseText);
     }
});

WCF 服务契约(Contract):

<ServiceContract()> _
Public Interface IDataShare
    <OperationContract()> _
    <WebInvoke(Method:="POST",
               BodyStyle:=WebMessageBodyStyle.Wrapped,
               RequestFormat:=WebMessageFormat.Json,
               ResponseFormat:=WebMessageFormat.Json)> _
    Function GetProgramsByEventType(eventTypeIds As String) As List(Of WF.DataContracts.Program.Program)

网络配置:

 <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceMetadata httpsGetEnabled="true"/>

                  contract="IDataShare"
                  bindingConfiguration="TransportSecurity"
                  behaviorConfiguration="EndpointBehavior"/>
        <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
      </service>
    </services>

Answer 1

我认为您的 web.config Tone 中需要一个带有 webHttpBinding 的端点。

<endpoint address=""
              binding="webHttpBinding"
              contract="IDataShare"
              bindingConfiguration="TransportSecurity"
              behaviorConfiguration="EndpointBehavior"/>
