ios - 在“IOS”中使用“rn-fetch-blob”上传图像的问题

问题描述

我rn-fetch-blob用来上传图片。这在 Android 中可以正常工作，但在 iOS 中不起作用。我使用data参数来响应创建图像链接，当我检查来自 iOS 的响应时，我发现dataiOS 响应中为空。我不知道为什么data参数status为 200 时为空。

我尝试了相同问题的所有答案，但它们对我不起作用！

上传图片代码：

export const UploadImageService2 = async (
  file: any,
): AxiosRequestConfig => {
  console.log("UploadImageService2");
  console.log("file: " + file);
  let seps = `${file.path}`.split('/');
  let filename = seps[seps.length - 1];
  var fp = file.path + "";
  const realPath = Platform.OS === 'ios' ? fp.replace('file://', '') : fp;
  console.log("fb: " + fp);
  console.log("filePath: " + realPath);

  const data = [
    {
      name: 'Files',
      filename,
      type: file.mime,
      // binary field data from a file path, use `wrap` method to wrap the path
      data: RNFetchBlob.wrap(decodeURIComponent(realPath)),
      // binary field data encoded in BASE64
      // data: RNFetchBlob.base64.encode(file),
    },
  ];
  console.log("dataObj: " + JSON.stringify(data));
  const response = await RNFetchBlob.fetch(
    'POST',
    `${BaseUrl}api/image`,

    {
      Authorization: 'Bearer ',
      'Content-Type': 'multipart/form-data',
    },
    data,
  );

  return {
    ...(response ? response : {}),
    ...file,
  };

};

这是由此调用的函数：

 _uploadSingleImage = async (file: any, sendCheckupForm) => {
    console.log("_uploadSingleImage");
    console.log("_file: " + JSON.stringify(file));
    let response = await UploadImageService2(file);
    // let response = await UploadImageService(file);
    console.log('resp=>>>', response)
    if (get(response, ['respInfo', 'status']) === 200) {
      console.log("okkk");
      const responseData = get(response, ['data'], file.name);
      console.log("responseData: " + JSON.stringify(responseData));
      const fileUrl = responseData.replace(/^"(.+(?="$))"$/, '$1');
      // const fileUrl = 'myTestImage';
      const attachedFiles = this.state.attachedFiles.map(i => i.path === response.path ? { ...i, status: 'success', FileName: fileUrl } : i);
      console.log("attachedFiles: " + JSON.stringify(attachedFiles));
      this.setState({ attachedFiles });
      console.log('fileUrl', fileUrl)
      this.setState({ receptionImage: fileUrl });
      if (sendCheckupForm) {
        // this.setState({showCheckupForm: false});
        this.props.sendCheckupForms(
          this.props.token,
          this.props.orderDetails.Id,
          {
            fileList: [fileUrl],
          },
        );
        this.props.getOrder(this.props.token, this.props.orderId);
      }
    } else {
      console.log("Erorrr");
      const attachedFiles = this.state.attachedFiles.map(i => i.path === response.path ? { ...i, status: 'error' } : i);
      this.setState({ attachedFiles });
    }
  };

这是rn-fetch-blobiOS 中的示例 Json 响应：

  type: 'utf8',
  respInfo: 
   { redirects: [ 'https://cp.azmayeshonline.com/api/image' ],

有人建议我如何处理这个问题吗？

解决方案

尝试使用：

data:RNFetchBlob.wrap(realPath)

代替：

data:RNFetchBlob.wrap(decodeURIComponent(realPath))

您的其余代码看起来不错。无论如何，您正在替换fp.replace('file://', '')iOS 所需的 .

这就是我在代码中的做法：

data:RNFetchBlob.wrap(this.state.file.uri.replace("file://", ""))
