關於微信小程式獲取使用者openid的問題
1.個人開發者是獲取不到OpenId：之前測試一直拿不到，讀者可以試一下。
2.獲取的程式碼和輸出：
//app.js
App({
globalData: {
appid: 'wx62a1hh8cfc28fdb',//appid需自己提供，此處的appid我隨機編寫
secret: '8990bf089dbsese3c951a1',//secret需自己提供，此處的secret我隨機編寫
},
onLaunch: function () {
var that = this
var user = wx.getStorageSync('user') || {};
var userInfo = wx.getStorageSync('userInfo') || {};
if ((!user.openid || (user.expires_in || Date.now()) < (Date.now() + 600)) && (!userInfo.nickName)) {
wx.login({
success: function (res) {
if (res.code) {
wx.getUserInfo({
success: function (res) {
var objz = {};
objz.avatarUrl = res.userInfo.avatarUrl;
objz.nickName = res.userInfo.nickName;
console.log(objz);
wx.setStorageSync('userInfo', objz);//儲存userInfo
}});
var d = that.globalData;//這裡儲存了appid、secret、token串
var l = 'https://api.weixin.qq.com/sns/jscode2session?appid=' + d.appid + '&secret=' + d.secret + '&js_code=' + res.code + '&grant_type=authorization_code';
wx.request({
url: l,
data: {},
method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
// header: {}, // 設定請求的 header
success: function (res) {
var obj = {};
obj.openid = res.data.openid;
obj.expires_in = Date.now() + res.data.expires_in;
console.log(obj);
wx.setStorageSync('user', obj);//儲存openid
}
});
} else {
console.log('獲取使用者登入態失敗！' + res.errMsg)
}
}
});
}
},
})
結果輸出（設定不校驗域名）：
VM682:1 工具未校驗合法域名、web-view（業務域名）、TLS 版本以及 HTTPS 證書。
app.js? [sm]:36
- {openid: "oBU4-5beiAsSLu40efAxL5d8iJe0", expires_in: NaN}
- expires_in:NaN
- openid:"o*********0efAxL5d8iJe0"
- __proto__:Object
