Ajax调用宁静的WS总是出错(提琴手得到了很好的响应) [英] Ajax call restful WS is always getting error (fiddler gets the good response)

问题描述

我用两种简单的方法(一种GET，另一种POST)制作了VS 2010中的Restfull WS.它们看起来像:

I have made Restfull WS in VS 2010 with two simple method (one GET, another POST). They look like:

[ServiceContract]
public interface IService1
    {

    [OperationContract]
    [WebInvoke(Method = "POST", UriTemplate = "createUser")]
    string createUser();

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml, UriTemplate = "loginUser/{email}/{password}")]
    string loginUser(string email, string password);

    }

这些方法的定义很简单:

Definition of these methods is simple:

public class Service1 : IService1
    {

 public string createUser()
        {
            return "Successful POST call !!! ";
        }

 public string loginUser(string email, string password)
        {
            return "Successful GET call !!! " + email + " - "+ password;
        }
  }

我已将此服务发布到IIS，并在浏览器中测试了我的方法(仅loginUser(GET)方法，无法通过浏览器测试createUser(POST)方法)，并且方法(loginUser)正常运行. 当我尝试通过jQuery AJAX调用方法时，总是收到错误通知，而没有任何通知.我检查了提琴手，并得到了正确的答复.

I have published this service to IIS and tested my method in browser (only loginUser (GET) method, cannot test createUser (POST) method by the browser) and method (loginUser ) work fine. When I tried to call method by jQuery AJAX, I am always getting error call without any notification. I checked my fiddler and there are the right response.

我的Ajax方法:

$(document).ready(function(){

$("#button2").click(function(){

  $.ajax({
   type: "GET",                 
   url: "http://localhost/AutoOglasi/Service1.svc/loginUser/bole/bole",

   success: function (response) {
    alert("respons  "+response);
   },
       error: function (request, status, error) {
    alert(request.responseText+" -- " + status + " --- "+ error);
   }
     });                

});

});

我在XML的mozila萤火虫部分中得到了这个信息:

I mozila firebug i section XML I get this:

XML解析错误:找不到元素位置:moz-nullprincipal:{ba25ef4a-f215-486e-b965-e70714c5af31}行号1，列1: ^

XML Parsing Error: no element found Location: moz-nullprincipal:{ba25ef4a-f215-486e-b965-e70714c5af31} Line Number 1, Column 1: ^

我在这里做错了，我只是想不通，因为提琴手给了我很好的答复?

What I am doing wrong here, I just cannot figure out, because fiddler is giving me good response?

推荐答案

您声明ResponseFormat = WebMessageFormat.XmlResponseFormat，返回的不是xml，而是字符串.它期望第一个字符为<.但是它是一个S，这就是为什么它在位置1找不到元素

You state ResponseFormat = WebMessageFormat.XmlResponseFormat and what you return is not xml but a string. It expects the first character to be a < but its a S thats why its not finding an element at position 1
