我做了一个使用react-native的TouchId身份验证示例,但是这个显示" TouchId不受支持"
任何人都有同样的问题吗?
我的设备是模拟器。但是当我在真实设备中运行它时问题是一样的。
有功能
_isSupported = async () => {
try {
await TouchId.isSupported()
Alert.alert('TouchId is supported!')
} catch(e) {
Alert.alert('TouchId is not supported!')
}
}
_trggerTouchId = async () => {
let description = 'Verify the existing mobile phone fingerprint using the home key'
//let title //fallback button title will be default as 'Enter Password'(localized)
//let title = "" //fallback button will be hidden
let title = "Verify Password" //fallback button title will be 'Verify Password'(unlocalized)
try {
await TouchId.verify({
description,
title,
});
//await TouchId.verify("123123123123");
Alert.alert('verify succeeded')
} catch(e) {
if (e.code == '-3') {
//fallback button is pressed
Alert.alert('errorCode: ' + e.code + ' verify failed, user wants to ' + title)
}
else {
Alert.alert('errorCode: ' + e.code + ' verify failed')
}
}
}
答案 0 :(得分:0)
几个月前我已经解决了这个问题。最后,问题出在应用程序上 TouchId 的设备配置和权限。代码很好。
