### 3、登录界面代码实现 ###

写一个登录按钮

实现点击登录方法代码以及说明

weixinLo() {
    				let that = this;
    				uni.login({
    					provider: 'weixin',
    					success: function(loginRes) {
    						that.$queue.showLoading('正在登录中...');
    						console.error(loginRes.authResult);
    //获取登录的token
    that.$queue.setData('weixinToken',loginRes.authResult.access_token);
    //获取登录的unionid 这个还是在开放平台做了 公众号 小程序 微信登录app关联才会有
    						that.$queue.setData('unionid', loginRes.authResult.unionid);
    //获取openid
    						that.$queue.setData('weixinOpenid', loginRes.authResult.openid);
    //这里吧数据全部提交给后台核验，有没有注册 注册了 后台代码会请求接口String s = HttpClient.doGet("https://api.weixin.qq.com/sns/userinfo?access_token=" + loginInfo.getToken() + "&openid=" + loginInfo.getOpenid()); 获取头像和昵称
    						that.$Request
    							.postJson('/user/loginApp', {
    								token: loginRes.authResult.access_token,
    								unionid: loginRes.authResult.unionid,
    								openid: loginRes.authResult.openid
    							})
    							.then(res => {
    								if (res.status === 0) {
    
    									//绑定手机号直接登录
    									that.getUserInfo(res.data.userId, res.data.uuid);
    								} else {
    									//没有绑定手机号让绑定手机号
    									uni.navigateTo({
    										url: '/pages/public/wxmobile'
    									});
    								}
    							});
    					}
    				});
    			},
