Question

我正在使用react-native-image-picker在我的iOS模拟器手机上为我的react native应用获取视频的文件路径。如何使用Amplify将其上传到S3？

import ImagePicker from 'react-native-image-picker';
import RNFetchBlob from 'react-native-fetch-blob';

class App extends Component {

 constructor(props) {
    super(props)

   this.state = {
     vidFileName: '',
     fileURI: '',
   }

    this.putFileInS3 = this.putFileInS3.bind(this);  
 }

  pickVideo = async () => {

    const options = {
       mediaType: 'video'
      };
      ImagePicker.launchImageLibrary(options, (response) => {
          console.log('Response = ', response);

         this.setState({ 
            vidFileName: response.fileName,
            fileURI: response.uri,
          });

         this.putFileInS3();
     }
  }

 readFile = (somefilePath) => {
     return RNFetchBlob.fs.readFile(somefilePath, 'base64').then(data => new 
      Buffer(data, 'base64'));
    } 


putFileInS3 = async () => 
  {
     RNFetchBlob.fs.readFile(this.fileURI).then(buffer => {
       Storage.put(vidFileName, buffer, { contentType: 'video/mp4' })
       conole.log('successfully uploaded video to bucket');
     }).catch(e => {
       console.log(e);
     });

  }

我正在尝试遵循以下操作：https://aws-amplify.github.io/docs/js/storage，在“在React Native应用程序中上传图像”部分。但是也许我错过了什么？你能帮忙吗？

Answer 1

此软件包非常适合将数据发送到S3 react-native-aws3中的存储桶。

如果在使用该软件包时需要任何帮助，请发表评论。

Answer 2

  putFileInS3 = async () => {
    RNFetchBlob.fetch('PUT', link,
      {
        'Content-Type': undefined
      },
      RNFetchBlob.wrap(Platform.OS === "android" ? this.state.fileURI :
        this.state.fileURI.replace("file://", "")))
      .then((resp) => {
        this.onImageUploadSuccess(resp)
      }).catch((err) => {
        this.onUploadFailure(err)
      })
  }
