WeChat Card Package Jump Mini Program
First sort out the mini program life cycle**小program life cycle
onLaunch 生命周期函數(shù)--監(jiān)聽(tīng)小程序初始化 當(dāng)小程序初始化完成時(shí)，會(huì)觸發(fā) onLaunch（全局只觸發(fā)一次） onShow 生命周期函數(shù)--監(jiān)聽(tīng)小程序顯示 當(dāng)小程序啟動(dòng)，或從后臺(tái)進(jìn)入前臺(tái)顯示，會(huì)觸發(fā) onShow onHide 生命周期函數(shù)--監(jiān)聽(tīng)小程序隱藏 當(dāng)小程序從前臺(tái)進(jìn)入后臺(tái)，會(huì)觸發(fā) onHide onError 錯(cuò)誤監(jiān)聽(tīng)函數(shù) 當(dāng)小程序發(fā)生腳本錯(cuò)誤，或者 api 調(diào)用失敗時(shí)，會(huì)觸發(fā) onError 并帶上錯(cuò)誤信息
Some examples
App({
onLaunch: function (options) {
console.log("app.js ---onLaunch---" );
},
onShow:function(){
console.log("app.js ---onShow---");
},
onHide:function(){
console.log("app.js ---onHide---");
},
onError: function (msg){
console.log("app.js ---onError---" );
},
globalData: {
userInfo: null
}
})The printing results are as follows
WeChat card package jump mini program can use the onshow method in app.js onshow(options) Pass options obtains parameters. It is worth noting here that all parameters obtained by options in onshow in app.js will be encapsulated in query, that is, options.query to obtain the parameters entering the mini program
Pitfall: The parameters are different and app.js has cache I thought that the parameters obtained in app.js are the same as those obtained on the general page onload. In fact, they are different. It is recommended to use onLoad: function (options) when the page is onloaded. ) {}Parameters are reassigned, so that the latest parameters will be obtained every time
As shown below
A little configuration of the attached card package
新增或者修改會(huì)員卡字段
https://api.weixin.qq.com/card/update?access_token=token
{
"card_id": "pEVBpxI6Fb7xqUUfrTiD738NZht4",
"member_card": {
"custom_field2": {
"name": "到家小程序",
"app_brand_pass": "home/pages/index/index",
"app_brand_user_name": "gh_69986111111@app"
}
}
}
特別注意的是：這個(gè)app_brand_user_name不是公眾號(hào)的而是小程序的原始ID加上@app
app_brand_user_name
這樣新增或者修改會(huì)員卡就可以進(jìn)行跳轉(zhuǎn)了;url也是需要的。
{
"card_id": "pEVBpxI6Fb7xqUUfrTiD738NZht4",
"member_card": {
"custom_field2": {
"url": "http://baidu.com",//這個(gè)URL必須存在
"name": "到家小程序",
"app_brand_pass": "home/pages/index/index",
"app_brand_user_name": "gh_69986111111@app"
}
}
