呼叫WCF服务404未找​​到 [英] Call WCF service 404 Not Found

问题描述

我创建了一个支持AJAX的WCF服务，我想用POST调用它。但该服务未找到404，我不明白为什么。我看到一些例子，但找不到，为什么我的服务无法访问。我已经改变了我的web配置，但没有任何区别。我该怎么办错了？

I've created an AJAX-enabled WCF Service and I want call it using POST. But the service was 404 not found and i don't understand why. I saw some examples but can't find why my service is inaccessible. I've already changed my web config but there is no difference. What do I do wrong?

namespace ATSite
{
    [ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class SendEmailService
    {
        [OperationContract]
        public string HelloWorld(string id)
        {
            return "Hello world " + id;
        }
    }
}

调用该服务：

Calling the service:

function helloWorld() {
    $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: "../SendEmailService.svc/HelloWorld",
        data: '{"Id": "2"}',
        dataType: "json",
        success: function (result) {
            onSuccess(result);
        },
        error: alert('Erro')
    });
}
function onSuccess(result) {
    alert(result);
}

这是我的web.config

This is my web.config

  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="ATSite.SendEmailServiceAspNetAjaxBehavior">
          <enableWebScript />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
      multipleSiteBindingsEnabled="true" />
    <services>
      <service name="ATSite.SendEmailService">
        <endpoint address="" behaviorConfiguration="ATSite.SendEmailServiceAspNetAjaxBehavior"
          binding="webHttpBinding" contract="ATSite.SendEmailService" />
      </service>
    </services>
  </system.serviceModel>

谢谢！

推荐答案

在WebInvoke属性为您提供了一些选项：

The WebInvoke attribute gives you some options:

    [WebInvoke(Method = "POST",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json)]
    public string MyAwesomeServiceMethod(Decimal value)
    {
        return value.ToString("F2");
    }
