rn-fetch-blob错误: RNFetchBlob.fetchBlobForm无法创建请求正文

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;
    }

控制台消息中的res抛出错误是

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

我正在尝试上传一个文件使用rn-fetch-blob和一些疯狂的事情发生了(‘file://file:///’，'file://')，由于file://file///输出似乎不正确，我认为这主要是rnfetchfile.replace的问题，请帮帮我

Answer 1

正如here所说，只需使用decodeURIComponent(uri)即可

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，这是一个需要技巧，它可以工作，但文件在uri中将不可用。您上传的文件将无法打开

我试着去做

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

希望这能帮上忙
