在React Native中将图像读取为二进制/blob可以通过以下步骤实现: 首先,你需要安装React Native的相关依赖库。可以使用以下命令安装: 代码语言:txt 复制 npm install react-native-image-picker --save 导入所需的库和组件: 代码语言:txt 复制 import React, { useState } from 'react'; import { View, Butt...
import { launchImageLibrary } from 'react-native-image-picker'; import { getImageURI, save } from '../Services'; const UploadImage = (props) => { const uploadImageOnS3 = async (file) => { const res = await fetch(file.uri); const blob = await res.blob(); let signedUriResp = a...
console.log(source)//You can also display the image using data://const source = { uri: 'data:image/jpeg;base64,' + response.data };this.setState({ avatarSource: source, }); } }); 完~ 官方文档https://github.com/react-native-image-picker/react-native-image-picker/blob/v2.3.4/docs...
首先,我们需要在我们的React Native组件中引入Image Picker库: ```jsx import ImagePicker from 'react-native-image-picker'; ``` 然后,我们可以使用`ImagePicker.showImagePicker`方法来显示图像选择器: ```jsx ImagePicker.showImagePicker(options, (response) => { ...
type: `image/${fileType}`, });}*/ this.uploadImage(result.base64); }; } 我试过添加注释代码,但没有上传任何东西,我试过代码现在的样子,这给了我错误Can currently only create a Blob from other Blobs,上传进度永远不会得到高于 0%。
