通过Android使用WCF POST进行400错误请求HTTP响应

Question

面对从android调用wcf服务的问题。 web.config中：

public class fizzbuzz {

private static MouseEvent fizzBuzz() {
    String fizz = "Fizz";
    String buzz = "Buzz";
    String fB = "Fizz buzz";
    int num = 0;

    while(num <= 100) {
        num++;

        if (num % 3 == 0 && num % 5 != 0) {
            System.out.println (fizz);
            }
        else if (num % 5 == 0 && num % 3 != 0) {
            System.out.println (buzz);
        }
        else if (num % 3 == 0 && num % 5 == 0){
            System.out.println (fB);
        }
        else {
            System.out.println(num);
        }
    }
    return null;
}

public static void ShowGUI(String[] args) {
    JPanel displayPanel = new JPanel();
    JButton okButton = new JButton("Start count");
    okButton.setFont(new Font("Malina Light", Font.TRUETYPE_FONT, 14));
    final JLabel Jlab = new JLabel();
    okButton.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            Jlab.getToolTipText(fizzBuzz());
        }
    });

    JPanel content = new JPanel();
    content.setLayout(new BorderLayout());
    content.add(displayPanel, BorderLayout.CENTER);
    content.add(okButton, BorderLayout.SOUTH);
    content.add(Jlab, BorderLayout.NORTH);

    JFrame window = new JFrame("Gui test");
    window.setContentPane(content);
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    window.setSize(250,  250);
    window.setLocation(100, 100);
    window.setVisible(true);;

}

public static void main(String[]args){
    //fizzBuzz();
    SwingUtilities.invokeLater(new Runnable() {
                @Override
                public void run() {
                    ShowGUI(args);
                }
            });
}

Service1.svc

[OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "UserLogin",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json,
          RequestFormat = WebMessageFormat.Json)]
        GPUsers UserLogin(GPUsers request);

这是GPUser类

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace GateP
{
    public class Service1 : IService1
    {
#region GPUser Login
        public GPUsers UserLogin(GPUsers request)
        {
            return request;
        }
        #endregion
    }
}

Android代码（java文件）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Web;
namespace GateP
{
    [DataContract]
    public class GPUsers
    {
        [DataMember]
        public int userID { get; set; }
        [DataMember]
        public string username { get; set; }
        [DataMember]
        public string password { get; set; }
        [DataMember]
        public string department { get; set; }
        [DataMember]
        public bool userActive { get; set; }
    }
}

到目前为止我尝试了什么： 使用visual studio的文件系统在iis上发布wcf服务。发布后，当我尝试在移动设备和桌面上浏览此地址192.168.5.103:12345时，它看起来很好但是当我使用wcf访问它时，它会抛出状态400，但请求错误。我不知道主要问题是什么。 附上截图请看看。我也在gradle中使用这一行 编译＆＃39; org.jbundle.util.osgi.wrapped：org.jbundle.util.osgi.wrapped.org.apache.http.client：4.1.2＆＃39;

工具：Visual Studio 2012和Android studio
