RN 从 IOS 中的 URL 获取 blob 下载 docx 或 pdf [英] RN fetch blob download docx or pdf from URL in IOS

问题描述

做了什么:

在 Android 中实现，并在 android 中的特定 DCIM 目录 中下载.在 ios 中使用 DocumentDir 下载 pdf 或 docx 文件.使用 "rn-fetch-blob": "^0.12.0";

Implemented in Android and its getting downloaded in specific DCIM directory in android. In ios using DocumentDir to download the pdf or docx file. Using "rn-fetch-blob": "^0.12.0";

错误:

在 IOS 中，它在控制台中显示消息:

In IOS it says the message in console :

文件保存到/var/mobile/Containers/Data/Application/E6FDC2DD-7FCA-44DC-85C4-A275078F8825/Documents/wow13.pdf

The file saved to /var/mobile/Containers/Data/Application/E6FDC2DD-7FCA-44DC-85C4-A275078F8825/Documents/wow13.pdf

要下载的代码是这样的:

The code to download is something like this :

downloadFileOnSuccess = async () => {
    let dirs =
      Platform.OS == 'ios'
        ? RNFetchBlob.fs.dirs.DocumentDir
        : RNFetchBlob.fs.dirs.DCIMDir;
    console.log(dirs, 'document path');
    RNFetchBlob.config({
      // response data will be saved to this path if it has access right.

      fileCache: true,
      path: dirs + `/wow13.pdf`,
    })
      .fetch(
        'GET',
        'https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf',
        {
          //some headers ..
        },
      )
      .then(res => {
        // the path should be dirs.DocumentDir + 'path-to-file.anything'
        console.log('The file saved to ', res.path());
      });
  };

但是我无法在我的 iphone 7 真机中找到文件的下载位置.我在 IOS 中缺少任何权限吗?尚未为 IOS 添加任何权限.

But i cannot get where the file is downloaded in my iphone 7 real device. Is there any permission i'm missing in IOS? Havent added any permission for IOS.

推荐答案

感谢 pruthvi，我得到了答案，对于 ios 我需要提示用户:

Thanks to pruthvi, i got the answer , for ios i need to prompt the user:

.then(resp => {
      // console.log(resp);
      if (Platform.OS === "ios") {
        RNFetchBlob.ios.openDocument(resp.data);
      }
    })
