模板版本:v0.2.2
[!TIP] Github 地址
请到三方库的 Releases 发布地址查看配套的版本信息:@react-native-oh-tpl/react-native-fingerprint-scanner Releases 。对于未发布到npm的旧版本,请参考安装指南安装tgz包。
进入到工程目录并输入以下命令:
npm install @react-native-oh-tpl/react-native-fingerprint-scanner
yarn add @react-native-oh-tpl/react-native-fingerprint-scanner
快速使用:
[!WARNING] 使用时 import 的库名不变。
import { View, Button } from "react-native";
import FingerprintScanner from 'react-native-fingerprint-scanner';
export default function App() {
const handleClick = () => {
FingerprintScanner
.isSensorAvailable()
.then((Biometrics) => {
}).catch((err) => {
});
}
const handleScanner = () => {
FingerprintScanner.authenticate({title: '1111'})
.then(() => {
}).catch((err) => {
});
}
const handleAttempt = () => {
let eror = FingerprintScanner.onAttempt()
}
const handleRelease = () => {
FingerprintScanner.release()
}
return (
<View>
<Button title="authenticate"
onPress={() => handleScanner()}
/>
<Button title="isSensorAvailable"
onPress={() => handleClick()}
/>
<Button title="onAttempt"
onPress={() => handleAttempt()}
/>
<Button title="release"
onPress={() => handleRelease()}
/>
</View>
);
}
本库已经适配了 Codegen
,在使用前需要主动执行生成三方库桥接代码,详细请参考 Codegen 使用文档。
目前 HarmonyOS 暂不支持 AutoLink,所以 Link 步骤需要手动配置。
首先需要使用 DevEco Studio 打开项目里的 HarmonyOS 工程 harmony
{
...
"overrides": {
"@rnoh/react-native-openharmony" : "./react_native_openharmony"
}
}
目前有两种方法:
- 通过 har 包引入(在 IDE 完善相关功能后该方法会被遗弃,目前首选此方法);
- 直接链接源码。
方法一:通过 har 包引入(推荐)
[!TIP] har 包位于三方库安装路径的
harmony
文件夹下。
打开 entry/oh-package.json5
,添加以下依赖
"dependencies": {
"@rnoh/react-native-openharmony": "file:../react_native_openharmony",
"@react-native-oh-tpl/react-native-fingerprint-scanner": "file:../../node_modules/@react-native-oh-tpl/react-native-fingerprint-scanner/harmony/fingerprint_scanner.har"
}
点击右上角的 sync
按钮
或者在终端执行:
cd entry
ohpm install
方法二:直接链接源码
[!TIP] 如需使用直接链接源码,请参考直接链接源码说明
打开 entry/src/main/ets/RNPackagesFactory.ts
,添加:
...
+ import { RNFingerprintScannerPackage } from '@react-native-oh-tpl/react-native-fingerprint-scanner/ts';
export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
return [
new SamplePackage(ctx),
+ new RNFingerprintScannerPackage(ctx)
];
}
点击右上角的 sync
按钮
或者在终端执行:
cd entry
ohpm install
然后编译、运行即可。
要使用此库,需要使用正确的 React-Native 和 RNOH 版本。另外,还需要使用配套的 DevEco Studio 和 手机 ROM。
请到三方库相应的 Releases 发布地址查看 Release 配套的版本信息:@react-native-oh-tpl/react-native-fingerprint-scanner Releases
[!TIP] "ohos.permission.ACCESS_BIOMETRIC"权限等级为system_basic 在
YourProject/entry/src/main/module.json5
补上配置
{
"module": {
"name": "entry",
"type": "entry",
···
"requestPermissions": [
+ { "name": "ohos.permission.ACCESS_BIOMETRIC" },
]
}
}
[!TIP] "Platform"列表示该属性在原三方库上支持的平台。
[!TIP] "HarmonyOS Support"列为 yes 表示 HarmonyOS 平台支持该属性;no 则表示不支持;partially 表示部分支持。使用方法跨平台一致,效果对标 iOS 或 Android 的效果。
Name | Description | Type | Required | Platform | HarmonyOS Support |
---|---|---|---|---|---|
authenticate: (value: authenticate) => Promise<void>; |
Starts Fingerprint authentication | function | No | All | YES |
isSensorAvailable: () => Promise<string> |
Checks if Fingerprint Scanner is able to be used by now. | function | No | All | YES |
release: () => void |
Stops fingerprint scanner listener, releases cache of internal state in native code | function | No | All | YES |
onAttempt: () => {message?: string} |
when users are trying to scan their fingerprint but failed | function | No | HarmonyOS | YES |
Name | Description | Type | Required | Platform | HarmonyOS Support |
---|---|---|---|---|---|
title |
the title text to display in the native | string | no | Android | yes |
subTitle |
the sub title text to display in the native | string | no | Android | no |
description |
the description text to display in the native | string | no | All | no |
cancelButton |
e cancel button text to display in the native | string | no | Android | no |
onAttempt |
a callback function when users are trying to scan their fingerprint but failed. | function | no | Android | no |
fallbackEnabled |
default to true, whether to display fallback button | boolean | no | IOS | no |
- Harmony的指纹认证只支持title修改,并没有subTitle,description,cancelButton,fallbackEnabled参数, issue#8
- authenticate的参数不支持onAttempt,authenticate的参数onAttempt为回调方法,接口type形式不支持function,所以将onAttempt方法单独抽离出来 issue#7
