小程序getPhoneNumber 解密手机号时，偶尔会出现填充无效，无法被移除
客户端
getPhoneNumber: function (e) {
let that=this;
wx.login({
success: function (res) {
if (e.detail.errMsg == ‘getPhoneNumber:fail user deny’) {
wx.navigateTo({
url: ‘…/…/pages/userLogin/userLogin’,
});
} else {
if (e.detail.errMsg == ‘getPhoneNumber:fail:cancel to confirm login’) {
wx.navigateTo({
url: ‘…/…/pages/userLogin/userLogin?url=’+that.data.url
});
}
else {
//console.log(res.code);
wx.request({
url: api.AESdecrypt,
data: {
‘encryptedDataStr’: e.detail.encryptedData,
‘code’: res.code,
‘iv’: e.detail.iv
},

header: { ‘content-type’: ‘application/x-www-form-urlencoded’ },
success: function (data) {
console.log(data);
app.globalData.userInfo = data.data.data;
setTimeout(function(){
wx.navigateBack({ changed: true });//返回上一页
},500);
},
error: function () {
