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;}@Overridepublic String toString() {return "User [id=" + id + ", username=" + username + ", password="+ password + "]";}}
