在 jquery ajax 调用 wcf 服务时从 http 移动到 https 时出错答案

【问题标题】：Error when moving from http to https on jquery ajax call to wcf service在 jquery ajax 调用 wcf 服务时从 http 移动到 https 时出错

【问题描述】：

我有一个托管在 .NET 3.5 Web 应用程序内的 IIS 6.0 中的 wcf 服务，它在 http 上运行良好，但是当我尝试实现 https/ssl 时，我收到一个 415 错误，并显示以下错误消息。我在请求和响应中都使用 json。

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

下面是我的客户端 jquery.ajax 调用、服务合同和 web.config。我在这里错过了什么？

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 服务合同：

<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)

web.config：

 <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceMetadata httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="EndpointBehavior">
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
    <wsHttpBinding>
      <binding name="TransportSecurity" sendTimeout="00:10:00" maxReceivedMessageSize="2147483647">
        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        <security mode="Transport">
          <transport clientCredentialType="None"  />
          <!--<message clientCredentialType="Certificate"  negotiateServiceCredential="true"/>-->
        </security>
      </binding>
    </wsHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="ServiceBehavior"
               name="DataShare">
        <endpoint address=""
                  binding="wsHttpBinding"
                  contract="IDataShare"
                  bindingConfiguration="TransportSecurity"
                  behaviorConfiguration="EndpointBehavior"/>
        <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>

【解决方案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"/>

见Expose webHttpBinding endpoint in a WCF service

和WCF service method to return json or soap

【解决方案2】：

请在 Ajax 调用中指定以下内容

contentType: "application/json; charset=utf-8"
