Uniapp Download Directory Setup Guide

In uniapp, you can specify the file download directory using the uni.downloadFile() method. The specific steps are as follows:

1. To start, make sure to import the uni.downloadFile() method in your Uniapp page.
2. Call the uni.downloadFile() method at the place where you need to download the file, and specify the download directory for the file.

The example code is as follows:

uni.downloadFile({
  url: 'http://example.com/file.pdf',
  success: function (res) {
    if (res.statusCode === 200) {
      uni.saveFile({
        tempFilePath: res.tempFilePath,
        success: function (saveRes) {
          console.log('文件下载成功，保存路径为：' + saveRes.savedFilePath);
        }
      });
    }
  }
});

In the code above, we downloaded a file using the uni.downloadFile() method, and after successful download, we saved the file to a specified directory using the uni.saveFile() method. The savedFilePath parameter in the saveFile() method can be used to specify the directory where the file is saved.

It is important to note that uniapp is a cross-platform development framework based on webview, and there may be some restrictions or differences on different platforms. The specific download directory settings may vary. It is recommended to adapt and adjust according to the specific project’s needs and platform characteristics.
