如题，获取OpenID：

uni.login({
	provider: 'weixin',
	success: function(res) {
		console.info("获取的resCode是：" + res.code);
		let url = 'https://api.weixin.qq.com/sns/jscode2session?appid=' + this.appid + '&secret=' +
			this.secret + '&js_code=' +
			res.code + '&grant_type=authorization_code';
		uni.request({
			url: url, // 请求路径
			success: result => {
				console.info("用户的OpenID是：" + result.data.openid);
			},
		});
	}
});
