微信公众号之智能绑定实现初始版本
微信公众号智能绑定实现步骤：
微信公众号智能绑定功能所有的步骤都是以模拟实现的。1.模拟打开微信公众帐号登录页面；
URL地址：https://mp.weixin.qq.com/
2.读取自己微信公众帐号的用户名和密码；
此处用户名和密码可以持久化到内存，文件，数据库，缓存中都可以，因为在此操作过程中需要多次验证。
3.配置微信公众号接入的URL和Token；
此处可以和步骤2一样选择持久化。（持久化可以应对多个微信公众帐号操作）
4.模拟微信公众号成功登录；
此处有时候因网络原因需要重试几次。
5.设置开发模式，服务器回调；
成功建立连接，启用开发模式此处模拟提交URL和Token。
6.完成步骤5后，在开发者页面读取AppId和AppSecret让其持久化；
此处根据请求到的页面代码，可以使用正则表达式或者使用：Document、Elements 对象定位AppId和AppSecret的位置，便于获取值。
7.在微信公众号设置页面，获取微信公众号信息持久化到数据库中；
如：公众号名称，原始帐号ID，公众号头像及二维码（此处头像可以下载保存到自己的服务器中），公众号类型等。
8.成功完成以上步骤后，可以根据自己的需求调用微信相关API获取数据。
a.获取粉丝信息持久化到数据库中。
b.创建自定义菜单。
说明：因为此处模拟人工操作，后期微信页面布局及页面相关属性变化，则智能绑定功能会失效，此时需要修改步骤5、7的内容。
如果后期微信公众号登录只能通过扫描二维码登录则智能绑定功能完全失效，目前企业号使用的就是扫描二维码+密码登录方式。
具体实现过程如下：

智能绑定执行类：
import org.oms.wechat.pojo.WechatAccountInfo;
import org.oms.wechat.pojo.WechatDevInfo;
/**

public class WechatBind {
private static String msg;
private static String url="http://omsvip.sinaapp.com/coreServlet";
private static String token="weixinCourse";
public static String SmartBind(String username, String password) {
// 开始绑定帐号
// 初始化登录信息
SmartBindUtil smartBind = new SmartBindUtil(username, password);
//登录成功后，在开发者中心获取开发者ID（AppId、AppSecret）
WechatDevInfo devInfo=smartBind.getWechatDev();

}
if(msg==null){
msg="智能绑定成功！";
}
return msg;
}
}
Result<T>.class 这个可以不要，也可以在前面文章中拷贝！
需要用到的2个Pojo 公众号信息类，代码如下：
/**
* 微信账号基本信息
*
* @author sunlight
*
*/
public class WechatAccountInfo {
/**
* 原始ID
*/
private String accountId;
/**
* 名称
*/
private String accountName;
/**
* 微信头像
*/
private String headImage;
/**
* 微信号
*/
private String wechatNumber;
/**
* 账号类型
*/
private String type;
/**
* 认证情况
*/
private String authenticate;
public String getAccountId() {
return accountId;
}
public void setAccountId(String accountId) {
this.accountId = accountId;
}
public String getAccountName() {
return accountName;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
public String getHeadImage() {
return headImage;
}
public void setHeadImage(String headImage) {
this.headImage = headImage;
}
public String getWechatNumber() {
return wechatNumber;
}
public void setWechatNumber(String wechatNumber) {
this.wechatNumber = wechatNumber;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getAuthenticate() {
return authenticate;
}
public void setAuthenticate(String authenticate) {
this.authenticate = authenticate;
}
@Override
public String toString() {
return "WechatAccountInfo [accountId=" + accountId + ", accountName="
+ accountName + ", headImage=" + headImage + ", wechatNumber="
+ wechatNumber + ", type=" + type + ", authenticate="
+ authenticate + "]";
}
}
开发者信息类：
/**
* 微信开发者信息
*
* @author sunlight
*
*/
public class WechatDevInfo {
private String appId;
private String appSecret;
public String getAppId() {
return appId;
}
public void setAppId(String appId) {
this.appId = appId;
}
public String getAppSecret() {
return appSecret;
}
public void setAppSecret(String appSecret) {
this.appSecret = appSecret;
}
@Override
public String toString() {
return "WechatDevInfo [appId=" + appId + ", appSecret=" + appSecret
+ "]";
}
}
最后附上执行结果：
注意：因为微信公众号页面等相关调整频繁，因此智能绑定微信公众号只是模拟用户登录，所以微信公众号官网页面等相关信息发生变化会导致智能绑定功能失效！
因此，微信修改一次我们的代码也会变化一次。
本文章因时间问题，编写的的不是很完美，等有时间重新整理一份！
