HttpClient调试android接口-通用方法

最近公司要我调试android接口，就封装了一下，记录下来。。做为笔记吧!

package com.dw.test;


public class User {
	  private String id;
	  private String username;
	  private String password;
	  
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", username=" + username + ", password="
				+ password + "]";
	}
	
}
