拾人牙慧篇之———QQ微信的第三方登录实现

时间:2021-04-05 16:01:08

一、写在前面

    关于qq微信登录的原理之流我就不一一赘述了,对应的官网都有,在这里主要是展示我是怎么实现出来的,看了好几个博客,有的是直接复制官网的,有的不知道为什么实现不了。我只能保证我的这个是我实现后才贴出来的,本文有看不懂的地方请结合官网看。(话说我感觉我写博客废话好多)

二、准备工作

    通过以下官网获得相应AppID和AppSecret以及对应的回调地址。

    QQ登录官网:https://connect.qq.com

    微信登录官网:https://open.weixin.qq.com

三、登录实现第三方

3.1、QQ授权登录实现

   这里的实现主要用JS_SDK来实现,通过这种实现回调地址基本没有什么用,区别于这种实现方式:如何在自己的网站上实现QQ授权登录?。步骤就不一一说了,直接上代码(红色部分为qq授权相关的,里面的appid和回调地址改成自己申请时候的既可)

这里用到的是 QC.Login.showPopup,期间遇到了showPopup 这种不能回调的情况,参考了:QC.Login.showPopup可有回调?

qq授权后台处理思路:通过点击qq登录,登录成功后回调,在回调中通过 QC.api("get_user_info")获取登录后的信息,在后台通过qq的openid来查询数据库,若是库中有值,则直接进入登录成功流程,若是没有值则跳转到手机号注册流程。(回调地址里面基本为空)

3.2、微信授权登录实现

  上面代码的蓝色部分即为微信登录的连接,相应地方改成申请的既可.

  这里有三个地方需要注意:

  1、地址需要改成转义后的,%3A%2F%2F就等于://这样的形式。

  2、若是前面微信开放平台的是https,对应的回调也是https。

  3、这里写的回调地址是http://www.xxxxxx.com/security/getWebchatCode.do,但是微信申请里写http://www.xxxxxx.com既可。

  下面看看微信登录成功后的后台处理代码

/**
* 微信登录获取code
*/
@RequestMapping(value = "/getWebchatCode.do")
public ModelAndView getWebchatCode(HttpServletRequest request, HttpServletResponse response) {
String code = request.getParameter("code");
System.out.println("微信登录获取code=="+code);
String url="https://api.weixin.qq.com/sns/oauth2/access_token?appid="+appid+"&secret=XXX&code="+code+"&grant_type=authorization_code"; Map<String, Object> map = new HashMap<String, Object>();
map.put("from", code);
try { JSONObject jb = HttpUtils.httpRequest(url,"GET",null);
System.out.println("通过code获取token=="+jb.toString());
String access_token= jb.getString("access_token"); JSONObject userinfo = HttpUtils.httpRequest("https://api.weixin.qq.com/sns/userinfo?access_token="+access_token+"&openid="+appid+"","GET",null);
System.out.println("通过token获取=="+userinfo.toString());
String loginName= userinfo.getString("nickname");
String openId=userinfo.getString("openid"); Member member = memberService.selectOneByWeixinOpenId(openId);
if (member != null ) {//通过qq唯一openID判断该qq是否之前用过,同时判断loginName是否唯一
member.setLastLoginTime(new Date());
memberService.update(member);
// 设置线程变量
CurrentThreadContext.setValue(CurrentThreadContext.CURRENT_USER_ID, member.getId());
CurrentThreadContext.setValue(CurrentThreadContext.CURRENT_MEMBER, member);
CurrentThreadContext.setValue(CurrentThreadContext.CURRENT_MANAGE_SHOP_ID, member.getManageShopId());
// 单点登录Cookie
Cookie cookie_sso = new Cookie(CurrentThreadContext.COOKIES_LOGIN_KEY, AESUtil.encrypt(loginName,
PropertiesUtil.getInstance().getValue("security.cipher.key")));
cookie_sso.setMaxAge(-1);
cookie_sso.setDomain(PropertiesUtil.getInstance().getValue("security.root.domain"));
cookie_sso.setPath("/");
response.addCookie(cookie_sso); // 用户Cookie
loginName = DESUtil.strEnc(loginName, PropertiesUtil.getInstance().getValue("security.cipher.key"), "",
"");
String shopFlage = "";
if (member.getManageShopId() != null) {
Shop t = new Shop();
t.setId(member.getManageShopId());
Shop shop = shopApiService.selectOne(t);
if (shop != null && shop.getStatus() != null
&& shop.getStatus().equals(ShopConstant.SHOP_STATUS_3)) {
shopFlage = member.getManageShopId().toString();
}
}
Cookie cookie_memberinfo = new Cookie(CurrentThreadContext.COOKIES_MEMBERINFO,
loginName + "|" + shopFlage + "|" + member.getId());
cookie_memberinfo.setMaxAge(-1);
cookie_memberinfo.setDomain(PropertiesUtil.getInstance().getValue("security.root.domain"));
cookie_memberinfo.setPath("/");
response.addCookie(cookie_memberinfo);
map.put("code", "200");
map.put("msg", "登录成功");
return new ModelAndView("redirect:/",map);
} else {
//qq授权的不存在,跳转到输入手机验证码的地方
map.put("code", "101");
Member membertemp = memberService.selectOneByLoginName(loginName);
if(membertemp!=null){
map.put("loginName", loginName+"_xima"+new Random().nextInt(1000));
}else{
map.put("loginName", loginName);
}
map.put("wqType", "weixin");
map.put("openId", openId);
/* map.put("msg", "用户名或密码不正确");*/
return new ModelAndView("security/qwRegister",map); }
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} return new ModelAndView("security/login",map);
}

主要是几次握手过程。

四、总结

   qq微信的第三方登录按照官方文档一步一步实习还是比较容易的,有什么问题可以交流交流。
