问题 I am using aria2c to download a quite large list of urls (~6000) organized in a text file. Based on this gist, I am using the following script to download all the files: #!/bin/bash aria2c -j5 -i list.txt -c --save-session out.txt has_error=`wc -l < out.txt` while [ $has_error -gt 0 ] do echo "still has $has_error errors, rerun aria2 to download ..." aria2c -j5 -i list.txt -c --save-session out.txt has_error=`wc -l < out.txt` sleep 10 done ### PS: one line solution, just loop 1000 times ###

问题 The code below is straight from google apis github for downloading a file from GCS. I changed it to be able to download a file to my local computer. If the file is larger than 33MB the app will stop attempting after 2 min or less. I think I read that app engine's limit is 32 or 33. I don't see anything in quotas to increase though. Can someone point me in the right direction as to how to manage this? if (blob.getSize() < 1_000_000) { // Blob is small read all its content in one request byte[]

问题 We are using forms authentication to authenticate users. In our application there is a page to download an exe. When I am debugging the code in visual studio, it allows only logged-in users to download the file. When other users try to download the file, they are automatically redirected to the login page. But when I am running this from a virtual directory, all users (whether logged-in or not) can download the file by accessing the direct path like http://testappln/foldername/test.exe . How

问题 I wrote a test that downloads the export file, but I also need to send this file through email. The problem is that filename is always different and I don't know how to look it up during the test. 回答1: You can retrieve the dynamic downloaded filename from the 'content-disposition' header. import { Selector, RequestLogger } from 'testcafe'; const url = 'https://demos.devexpress.com/ASPxGridViewDemos/Exporting/Exporting.aspx'; const logger = RequestLogger({ url, method: 'post' }, {

The set of google sheets I'm trying to download has over 100 sheets, which makes downloading them one by one with gsheet massively inconvenient - does anyone know of any R packages that automate this or of any way to loop through all of
