我知道这个问题之前已经发布过多次，但即使调查这些问题的解决方案也没有奏效。所以，最后我不得不发布这个问题： -

这是我的 ajax 脚本

 function CallWebservice()
 {
    var textboxvalue = $('#TextBox1').val();
        $.ajax({
            url: "http://localhos/Service1.svc/GetData",
            type: "POST",
            data: '{"value": "' + textboxvalue + '"}',
            dataType: "json",
            processdata: true,
            contentType: "application/json; charset=utf-8",
            success: function (res) { 
            alert(res);
             },
        });
   }

以下是服务接口代码：

namespace WcfService1
{
[ServiceContract]
[System.Web.Script.Services.ScriptService]
public interface IService1
{

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

    [OperationContract]
    CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
    }
 }

服务代码

   [AspNetCompatibilityRequirements(RequirementsMode=        AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
    public string GetData(string value)
    {
        return (value == "Bose") ? "true" : "false";
    }
}

问题：

- 代码有什么问题吗？
-我无法拨打 WCF 服务电话？Firebug 说 400 错误请求？

请确保您能够在 IIS 中浏览该服务。您的 web.config<services>似乎缺少节点。还有一些奇怪的事情：

您的绑定是 webHttpBinding，但绑定配置是带有用户名/密码的消息安全的 basicHttpBinding。

binding="webHttpBinding"
      bindingConfiguration="BasicHttpBinding_IService1"

还有名称为“BasicHttpBinding_IService1”的服务行为。

如果您尝试 WCF REST，请创建一个新的解决方案并重试。
