Question

嗨，我正在尝试在我的节点js应用程序中使用jquery ajax调用WCF服务。

它不会给出任何错误，但是该服务未调用。但是，当我在不使用节点js的情况下尝试此代码时，它会起作用。

如何从节点js调用wcf服务

WCF服务合同

 [ServiceContract]
    public interface IService1
    {

        [OperationContract]
        [WebInvoke(Method = "POST",
               BodyStyle = WebMessageBodyStyle.Wrapped,
               ResponseFormat = WebMessageFormat.Json)]
        string GetData(int value);

        [OperationContract]
        CompositeType GetDataUsingDataContract(CompositeType composite);

        // TODO: Add your service operations here
    }

WCF服务

 public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
     }

Web.config

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="EndpBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
    <services>
      <service behaviorConfiguration="ServiceBehavior" name="Service1">
        <endpoint address="" binding="webHttpBinding" contract="IService1" behaviorConfiguration="EndpBehavior"/>
      </service>
    </services>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--
        To browse web app root directory during debugging, set the value below to true.
        Set to false before deployment to avoid disclosing web app folder information.
      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>

还有我的Node js代码

var jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { window } = new JSDOM();
const { document } = (new JSDOM('')).window;
global.document = document;

var $ = jQuery = require('jquery')(window);

var showStb = function(){
    try{    
    $.ajax({
                type: "POST",              
                url: "http://localhost:56147/Service1.svc/GetData",
                data: '{"value": "2"}', 
                dataType: "jsonp",
                contentType: "application/json", // content type sent to server
                success: function(data){
                    console.log(data);
                },
                error: function(err){
                    console.log(err);
                }
            });


    }
    catch(e){
                console.log( e);
    }
};

showStb();

假定您的服务托管正确。让我尝试重新排序并向您解释每个属性。

 $.ajax({
               //where is thre url present
                url: "http://localhost:56147/Service1.svc/GetData",
                //what kind of request
                method: "post", 
                //contenttype that we will send it to the server 
                contentType: "application/json;charset-utf-8", 
                //lets convert the data to json and send it to the server
                data: JSON.stringify({value: "2"}), 
                dataType: "json",
                //when the request is success
                success: function(data){
                    console.log(data);
                },
                //if any error 
                error: function(err){
                    console.log(err);
                }
            });

这应该可以完成工作，而不是使用jsonp。
