从本地存储反应本地上传视频

Question

我正在使用RNfetchblob将视频从手机存储上传到api。这是我从RNFetchblob文档中复制的代码。

RNFetchBlob.fetch('POST', 'https://content.dropboxapi.com/2/files/upload', {
// dropbox upload headers
Authorization : "Bearer access-token...",
'Dropbox-API-Arg': JSON.stringify({
  path : '/img-from-react-native.png',
  mode : 'add',
  autorename : true,
  mute : false
}),
'Content-Type' : 'application/octet-stream',
// Change BASE64 encoded data to a file path with prefix `RNFetchBlob-file://`.
// Or simply wrap the file path with RNFetchBlob.wrap().
}, RNFetchBlob.wrap(PATH_TO_THE_FILE))
.then((res) => {
   console.log(res.text())
 })
 .catch((err) => {
   // error handling ..
 })

我对两个术语感到困惑1.path 2.PATH_TO_THE_FILE 如何在手机上找到视频路径。什么是PATH_TO_THE_FILE
