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

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);
}
},
