php 获取小程序码 （B类接口）

• 生成小程序码的php代码

//	生成小程序码
$wechatObj	=	new \Wechat();//这是个类 这里有小程序appid和密码
$url =	"https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=".$wechatObj->getAccessToken();

• 　小程序端获取二维码中带的参数

/**
* 生命周期函数--监听页面加载
*/
onLoad: function(option) {
console.log(option)
if(option.id){
this.setData({ id: option.id });
this.data.business_id = option.id;
this.loadData(option.id);
}

//接受二维码扫码并获取二维码中的参数
if (option.scene){
const ids = decodeURIComponent(option.scene).split('=')[1];
console.log("ids", ids);
this.setData({ id: ids });
this.data.business_id = ids;
this.loadData(ids);
}

},
