Question

[Андрей Астафьев]

Пытаюсь отослать файл на сервер
Получаю информацию о файле из галлереи с помощью react-native-image-picker

const file = {
  contentType: "image/jpeg"
  data: "/9j/4AAQSkZJRgABAQAAAQABAAD/4VGmRXhpZgAASUkqAAgAAA"
  fileName: "image-9b223fbf-8401-4668-99b7-80db6da5ac03.jpg"
  fileSize: 210829
  fullName: "image-9b223fbf-8401-4668-99b7-80db6da5ac03.jpg"
  height: 960
  isVertical: true
  originalRotation: 0
  path: "/storage/emulated/0/Pictures/images/image-9b223fbf-8401-4668-99b7-80db6da5ac03.jpg"
  tag: "common"
  timestamp: "2020-11-11T07:34:04Z"
  type: "image/jpeg"
  uri: "content://media/external/images/media/34"
  url: "content://media/external/images/media/34"
}

async saveFile (file: any, tag: string = 'common') {
    const token = await AsyncStorage.getItem('access.token');
    
    var myHeaders = new Headers();
    myHeaders.append("Authorization", `Bearer ${token}`);
    myHeaders.append("Content-Type", "multipart/form-data");
    // myHeaders.append("Content-Type", "application/json; charset=utf-8");

    var formdata = new FormData();
    formdata.append("tag", tag);
    formdata.append("file", file.data);
    // formdata.append("file", `data:${file.contentType};base64,${file.data}`);
    // formdata.append("file", {
    //   type: file.type,
    //   name: file.fileName,
    //   uri: file.uri
    // });
    var requestOptions = {
      method: 'POST',
      headers: myHeaders,
      body: formdata,
      // redirect: 'follow'
    };
    
    fetch("https://hozu-dev.car.tatar:5001/api/file", requestOptions)
      .then(response => response.text())
      .then(result => console.log(result))
      .catch(error => console.log('error', error));
