無法使用JSONP將參數傳遞給REST/WCF服務

我想使用JSONP調用WCF服務。有兩種方法， 1.「你好」的方法，它不需要任何參數。這工作正常 2.「Hello1」方法需要一個字符串參數。這不能正常工作。它應該返回我傳遞的價值。無法使用JSONP將參數傳遞給REST/WCF服務

以下是代碼片段

Server代碼

using System.Runtime.Serialization; 
using System.ServiceModel; 
using System.ServiceModel.Activation; 
using System.ServiceModel.Web; 

namespace WcfService1 
{ 

    [ServiceContract(Namespace = "JsonpAjaxService")] 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class Service1 
    { 

     [WebGet(ResponseFormat = WebMessageFormat.Json)] 
     public string Hello() 
     { 
      return "I got the call"; 
     } 

     [WebGet(ResponseFormat = WebMessageFormat.Json)] 
     public string Hello1(string str) 
     { 
      return "Hi, you passed me " + str; 
     } 

    } 

}

Web配置代碼

<?xml version="1.0"?> 
<configuration> 
    <system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    <authentication mode="None" /> 
    </system.web> 
    <system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> 
    <standardEndpoints> 
     <webScriptEndpoint> 
     <standardEndpoint name="" crossDomainScriptAccessEnabled="true"/> 
     </webScriptEndpoint> 
     <webHttpEndpoint> 
     <standardEndpoint name="" helpEnabled="True" 
      automaticFormatSelectionEnabled="true" /> 
     </webHttpEndpoint> 
    </standardEndpoints> 
    </system.serviceModel> 
</configuration>

誰能告訴我什麼是錯在日同時呼籲Hello1方法

嘗試傳送數據爲對象，而不是作爲一個串E代碼：

function Hello1() { 
    debugger; 
    var uesrid = "1"; 
    Type = "GET"; 
    ContentType = "application/json; charset=utf-8"; 
    Url = "http://localhost:52136/Service1.svc/Hello1"; 
    DataType = "jsonp"; //ProcessData = false; 
    method = "Hello1"; 
    Data = {str : 'abc'}; 
    //debugger; 
    CallService(); 
}

非常感謝，它像一個魅力。涼 –

using System.Runtime.Serialization; 
using System.ServiceModel; 
using System.ServiceModel.Activation; 
using System.ServiceModel.Web; 

namespace WcfService1 
{ 

    [ServiceContract(Namespace = "JsonpAjaxService")] 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class Service1 
    { 

     [WebGet(ResponseFormat = WebMessageFormat.Json)] 
     public string Hello() 
     { 
      return "I got the call"; 
     } 

     [WebGet(BodyStyle = WebMessageBodyStyle.Bare, 
     ResponseFormat = WebMessageFormat.Json, 
     UriTemplate = "SetQuoteEntities?str={str}")] 
     public string Hello1(string str) 
     { 
      return "Hi, you passed me " + str; 
     } 

    } 

}

當我修改的屬性webGet它爲我工作。
