http-status-code-404

问题 I am currently working on a Telegram Bot project which requires me to download Images send by users to the bot. I followed the API documentation which says to use the getFile call to access the file_path. The file should then be found using the path (https://api.telegram.org/file/bot/) Everything works until I try to access the file using the address above. It always returns 404. However not a json containing the 404 message, but a black screen in the browser and 404 in the page response.

问题 I recently created a process that reads/writes contacts in users' mailboxes on-prem via Graph. This process works as expected most of the time but certain times it fails with a 404. I've narrowed it down to the datacenter Graph is using. I've verified nothing is causing this issue at the network perimeter and no API calls are actually reaching the Exchange servers when the 404 is returned. 404 - North Central US DEBUG: GET https://graph.microsoft.com/v1.0/users/zHM.Test%40fomain.com/contacts?

问题 How to handle Image.network when the url is wrong or the destination leads to 404. for example try Image.network('https://image.tmdb.org/t/p/w92') 回答1: I have handled the network image issue related to 404 by using an errorBuilder.
