Question

async postFileUpload(payload) {
    const rnfetchfile = RNFetchBlob.wrap(payload.uri);
    try {
    console.log(
        'POST',
        'https://******.***.**/******/***/upload_*******_file',
        {
          ...this.config,
          'Content-Type': 'multipart/form-data',
        },
        [
          // element with property `filename` will be transformed into `file` in form data
          {
            name: 'files',
            filename: payload.name,
            data: rnfetchfile.replace('file://file:///', 'file://'),
          },
        ],
      );
      const res = await RNFetchBlob.fetch(
        'POST',
        'https://******.***.**/******/***/upload_*******_file',
        {
          ...this.config,
          'Content-Type': 'multipart/form-data',
        },
        [
          // element with property `filename` will be transformed into `file` in form data
          {
            name: 'files',
            filename: payload.name,
            data: rnfetchfile.replace('file://file:///', 'file://'),
          },
        ],
      );
    const response = JSON.parse(res.data);
      console.log('api upload adpostimage', response);
      return response;
    } catch (err) {
      console.log('postFileUpload', err.response, err);
      Toast.show(err.response.data.message, Toast.SHORT);
      throw err.response.data;
    }

res 抛出错误
在控制台消息是

POST https://******.***.**/******/***/upload_*******_file {Content-Type: "multipart/form-data", Authorization: "Bearer ******.***.*****"} 
[{…}]
0:
name: "files"
filename: "*****.pdf"
data: "RNFetchBlob-file://Users/********/tmp/*****/B****.pdf"}

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

如 here说只是用 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'}
]
