wx.getSetting()方法是异步么？为何会导致死循环呢
我有尝试将这个授权作为一个单独的方法，并通过一个简单的while循环来进行保证最后的结果一定是用户授权，可是最后却发现会导致死循环，代码会一直console.log(userInfo)，代码块如下：
function checkSetting() { var userInfo = false while (!userInfo) { console.log(userInfo) wx.getSetting({ success: res => { console.log("res.authSetting['scope.userInfo']="+res.authSetting['scope.userInfo']) userInfo = res.authSetting['scope.userInfo'] } }) //如果没有获取到授权 if (!userInfo) { wx.showModal({ title: '提示', content: '为保证程序正常运行，请允许小程序获取您公开的用户信息', showCancel: false, confirmText: '去授权', success: res => { if (res.confirm) { wx.openSetting({ success: res => { console.log("2es.authSetting['scope.userInfo']=" + res.authSetting['scope.userInfo']) userInfo = res.authSetting['scope.userInfo'] } }) } } }) } }
