npm i react-scan-qr-codeYARNyarn add react-scan-qr-codeExample UsageAfter reading and performing the previous steps, you should be able to import the library and use it like in this example:import React, { useState } from 'react'; import { QrScanner } from 'react-scan-qr-code'; const...
<QRScanner /> : null; return ( <div className="appContainer"> <div className="main"> <Button text="Scan QR Code" onClick={openHello} /> </div> <Modal isOpen={isOpen} title="Scan QR Code" closeModal={closeModal}> <div>{qrScanner}</div> </Modal> </div> ); }...
yarn add react-qrcode-scan // or npm install react-qrcode-scan --save import { QRScaner, Camera } from "react-qrcode-scan"; export default class QRReader extends React.Component<RenderProps, RenderState> { ... render() { const { results, camera } = this.state; return ( <Camera on...
npm install react-qr-reader ``` 然后,可以在React组件中使用`QrReader`组件来实现扫码操作: ```jsx import React, { useState } from 'react'; import QrReader from 'react-qr-reader'; const QRCodeScanner = () => { const [result, setResult] = useState(''); const handleScan = (data) => ...
import { StyleSheet, Animated, PermissionsAndroid, default as Easing, ImageBackground, View, Text, }from 'react-native'; let camera; const ScanQRCode = () => { const moveAnim =useRef(new Animated.Value(-2)).current; useEffect(() => { ...
(<Buttontitle="扫描二维码"onPress={onScanPress}/>):(<Viewstyle={styles.cameraContainer}><Camerastyle={styles.cameraPreview}type={Camera.Constants.Type.back}ref={cameraRef}onBarCodeScanned={onBarCodeScanned}onCameraReady={onCameraReady}/><Viewstyle={styles.buttonContainer}><Buttontitle="退出"on...
react-qrcode-scan React componnent write by typescript for scan qrcode. Base on instascan.js Usage yarn add react-qrcode-scan // or npm install react-qrcode-scan --save import { QRScaner, Camera } from "react-qrcode-scan"; export default class QRReader extends React.Component<RenderPro...
In continuous scan mode, we can draw QR code overlays to show which QR codes are detected. We can do this using SVG which has been discussed in a previous article. Add an SVG element in JSX: const [viewBox,setViewBox] = useState("0 0 1920 1080"); //... <svg viewBox={viewBox...
下面开始上业务功能代码:可直接新建一个ScanQRCode.js文件把代码拷贝进去。后续直接引用该组件即可。 import { RNCamera } from 'react-native-camera' import React, { useCallback, useState } from 'react'; import { StyleSheet, Animated, View,
从照片里面获取GPS信息。可交换图像文件常被简称为EXIF（Exchangeable image file format），是专门为数码相机的照片设定的，可以记录数码照片的属性信息和拍摄数据，EXIF信息不支持png，webp等图片格式。在
