react-native-secure-storage

这个包基于 react-native-secure-storage 并做了一些定制。

Getting started

$ npm install react-native-secure-storage --save

或

$ yarn add react-native-secure-storage

Mostly automatic installation

$ react-native link react-native- secure-storage

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-secure-storage and add RNSecureStorage.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNSecureStorage.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import com.aaxis.RNSecureStoragePackage; to the imports at the top of the file
• Add new RNSecureStoragePackage() to the list returned by the getPackages() method

1. Append the following lines to android/settings.gradle: include ':react-native-secure-storage' project(':react-native-secure-storage').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-secure-storage/android')
2. Insert the following lines inside the dependencies block in android/app/build.gradle: compile project(':react-native-secure-storage')

Usage

import SecureStorage, { ACCESS_CONTROL, ACCESSIBLE, AUTHENTICATION_TYPE } from 'react-native-secure-storage'

async() => {
  const config = {
    accessControl: ACCESS_CONTROL.BIOMETRY_ANY_OR_DEVICE_PASSCODE,
    accessible: ACCESSIBLE.WHEN_UNLOCKED,
    authenticationPrompt: 'auth with yourself',
    service: 'example',
    authenticateType: AUTHENTICATION_TYPE.BIOMETRICS,
  }
  const key = 'someKey'
  await SecureStorage.setItem(key, 'some value', config)
  const got = await SecureStorage.getItem(key, config)
  console.log(got)
}

Methods

这个库现在已经实现了 getItem, setItem, removeItem 和 getAllKeys 方法 < code>AsyncStorage 来自 React Native。 它不支持回调并将 callback 参数替换为 option 参数。

此外，这个库有一个 getSupportedBiometryType() 方法，它返回一个 BIOMETRY_TYPE 指示设备支持的生物识别类型，以及一个 canCheckAuthentication([{ authenticationType }] ) 方法检查指定的 authenticationType 是否可用。
