我正在尝试使用rn-fetch-blob上传文件，并且发生了一些疯狂的事情 rnfetchfile.replace（'file：// file：///'，'file：//'），因为file：// file ///输出似乎不正确我认为这主要是ios问题，请帮帮我

Answer 1

here所说的只是使用decodeURIComponent(uri)

这是我的代码：

const realPath = Platform.OS === 'ios' ? uri.replace('file://', '') : uri;

const data = [
  {
     name: 'file',
     filename,
     type,
     data: RNFetchBlob.wrap(decodeURIComponent(realPath)),
  },
  {name: 'bla', data: 'bla'}
]

Answer 2

尝试将file：// file：//替换为''空字符串。

rnfetchfile.replace('file://file:///', '')

– @Abhishek Ghosh评论说这是一个有用的技巧，它将起作用，但该文件在uri中将不可用。您上传的文件将不会打开

我尝试做

data: decodeURIComponent(rnfetchfile.replace('file://file:///', 'file:///')

，并且希望能对您有所帮助
