1、首先引入
2、使用auth方法
3、配置
3 - 1 首页需要到微信开放平台去申请审核 https://open.weixin.qq.com/
注：如果需要ios 和 安卓 使用，请注意上图 将ios和android应用都勾选上
4、auth方法成功之后，使用getToken方法
5、在使用getToken方法成功后，使用getUserInfo方法
将获取到的用户信息按需要逻辑处理
附上小编的项目代码
小编的代码有处理是否绑定的逻辑以及登录等，大家只需参考wx登录部分即可
html部分
<div class="aui-col-xs-2" style="text-align: center;" tapmode onclick="wxauth()"> <i class="iconfont icon-liaotian icon_bg2"></i> <div class="aui-grid-label" style="display:block;margin-top:10px;">微信</div></div>
js部分
