WCF：字符0处的输入结束

Question

我正在尝试从Android客户端调用WCF服务，我得到了End of input at character 0 of 错误。当我用WCF客户端测试测试它时服务工作正常，但是当我在Android客户端中尝试它时，它没有生成输入错误结束...我不知道我错过了什么..

所以这是我的代码

EmployeeInfo.svc

namespace EmployeeServices
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "EmployeeInfo" in code, svc and config file together.



        public class EmployeeInfo : IEmployeeInfo
        {
            public Employee GetEmployee(int employeeId)
            {
                Employee employeeInfo = GetEmployees(employeeId).Where(employee => employee.EmployeeId == employeeId).FirstOrDefault();
                return employeeInfo;
            }

            private List<Employee> GetEmployees(int employeeId)
            {

                return new List<Employee> {
                    new Employee { EmployeeId = 11, FirstName = "Waqas", LastName = "Yousuf", Address="A-175 Block 1" , BloodGroup = "B+" },
                    new Employee { EmployeeId = 22, FirstName = "Moiz", LastName = "Ahmed", Address="B-176 Block 2" , BloodGroup = "O-" },
                    new Employee { EmployeeId = 33, FirstName = "Waqas", LastName = "Raza", Address="C-177 Block 3" , BloodGroup = "A+" },
                    new Employee { EmployeeId = 44, FirstName = "Yasir", LastName = "Amin", Address="D-178 Block 4" , BloodGroup = "AB+" },
                    new Employee { EmployeeId = 55, FirstName = "Adeel", LastName = "Ali", Address="E-179 Block 5" , BloodGroup = "B+" } };
            }
        }
    }

IEmployeeInfo.cs

namespace EmployeeServices
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IEmployeeInfo" in both code and config file together.

    [ServiceContract(Namespace = "http://services.example.com")]
    public interface IEmployeeInfo
    {
        [OperationContract]
        [WebGet(UriTemplate = "GetEmployee/{employeeId}",
            BodyStyle = WebMessageBodyStyle.WrappedRequest,
            ResponseFormat = WebMessageFormat.Json,
            RequestFormat = WebMessageFormat.Json)]
        Employee GetEmployee(int employeeId);

    }

    [DataContract]
    public class Employee
    {
        [DataMember]
        public int EmployeeId { get; set; }
        [DataMember]
        public string FirstName { get; set; }
        [DataMember]
        public string LastName { get; set; }
        [DataMember]
        public string Address { get; set; }
        [DataMember]
        public string BloodGroup { get; set; }
    }
}

这是web.config

<?xml version="1.0"?>

    <compilation debug="true" targetFramework="4.0" />

  <system.serviceModel>

      </service>
    </services>
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

Android方法

try {
            String SERVICE_URI = "http://192.168.1.4:1234/Employeeinfo.svc";

            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpGet request = new HttpGet(SERVICE_URI + "/GetEmployee/11");

            request.setHeader("Accept", "application/json");
            request.setHeader("Content-type", "application/json");


            HttpResponse response = httpClient.execute(request);


            HttpEntity responseEntity = response.getEntity();

            // Read response data into buffer
            char[] buffer = new char[(int)responseEntity.getContentLength()];
            InputStream stream = responseEntity.getContent();
            InputStreamReader reader = new InputStreamReader(stream);
            reader.read(buffer);
            stream.close();

            JSONObject Emp = new JSONObject(new String(buffer));

            // Populate text fields
            ed1.setText(Emp.getString("Address"));
            ed2.setText(Emp.getString("BloodGroup"));
            ed3.setText(Emp.getString("EmployeeId"));
            ed4.setText(Emp.getString("FirstName"));
            ed5.setText(Emp.getString("LastName"));



        }
        catch (Exception e) {
            e.printStackTrace();
  lblStatus.setText(e.getMessage());
        }     

我正在工作几天，以了解如何从Android应用程序调用WCF服务，我在这里掖...请帮助

只需将此值的大小增加为图像上显示的6553600。

WebGet(UriTemplate = "GetEmployee/{employeeId}",
            BodyStyle = WebMessageBodyStyle.WrappedRequest,
            ResponseFormat = WebMessageFormat.Json,
Method="GET",
            RequestFormat = WebMessageFormat.Json)]
