react-native - FormData 在 react native 中发送字符串值而不是视频文件

Question

我正在尝试使用 FormData 将视频上传到后端服务器。但是，当上传视频文件时，我在后端获取字符串值而不是视频文件。谢谢

const formData = new FormData();
formData.append('dare_id', `${encrypted_id}`);
formData.append(
  'video',
  Platform.OS === 'android'
    ? uri                                 //local video file uri
    : uri.replace('file://', ''),        //local video file uri
);

fetch(UPLOAD_URL, {
  method: 'POST',
  headers: {
    'Content-Type': 'multipart/form-data',
    Authorization: `Bearer ${token}`,
    Accept: 'application/json',
  },
  body: formData,
})
  .then(res => res.json())
  .then(responseJson => {
    console.log(responseJson);
  })
  .catch(error => {
    console.log(error, ' error uploading');
  });

要上传文件，您还必须插入文件类型和文件名。这是他的代码:

let formData=new FormData();
formData.append({uri:yourNormalizedUri,type:”I dont know exactly but it should be video/mp4 google it”, name:”video.mp4”});
