由 依然范特西╮ 提交于 2021-02-11 09:47:55
问题 In VFS proxy, How I can handle errors? For example in below cases: If VFS is not able to connect to SFTP server due to different reasons(like wrong password, directory not exist etc). I am able to see Warning in console log but I want to send a mail or want to do some other stuff if connection is not possible. If the folder does not exist where we have to move file after reading.

问题 Is it possible to catch all errors for mysqli calls in one place with one statement or do I have to check each mysqli call individually for an error? I want to do something along the lines of: if(mysqli_error_occurs_anywhere_in_web_app) { die('<html><head></head><body>database error</body></html>'); } basically if a mysqli error occurs anywhere I want to output an html database error document. is this possible? 回答1: You could alternately wrap all your queries on your own query function,

NServiceBus 6 callback client never gets a callback when the request handler fails

由 |▌冷眼眸甩不掉的悲伤 提交于 2021-02-10 20:14:02
问题 Using NServiceBus 6's Callback feature I have found no way to alert the client that the request handler failed. The request handler will go through all the recoverability steps, and eventually put the message into the error queue. Meanwhile, the client just sits there waiting for its reply. // Client code (e.g. in an MVC Controller) var message = new FooRequest(); var response = await endpoint.Request<FooReponse>(message); // Handler code public class FooRequestHandler : IHandleMessages

问题 I want to return a failed validation attempt message in JSON. I used something like this before, which was working on Laravel 5, I believe... if ($validator->fails()) { return response()->json($validator->messages(), 200); } However, for our new project we are using Laravel 6 and the above just returns a blank page. In Laravel 6 the following returns the error message successfully, albeit not in JSON... if ($validator->fails()) { $msg = $validator->messages(); dd($msg); } There must be a

HTTP Error 307: Temporary Redirect in Python3 - INTRANET

由 眉间皱痕 提交于 2021-02-10 15:54:56
问题 The code generates a series of URLs and searches them for a specific string. As the website requires login information: I logged in the website through my browsers. And for more checks, I tried only one complete URL(of the same website) with no values and encoding and it worked perfectly well. So I supposed the login information shouldn't be the problem. I did try to add log-in info through the code, but as it itself brought up a series of errors, I wanted to see if that is really necessary

Rescue CSV::MalformedCsvError: Illegal quoting in line n

由 白昼怎懂夜的黑 提交于 2021-02-09 10:51:30
问题 Seems a common issue to have a buggy CSV file when attempting to parse to an array, AR model import, etc. I haven't found a working solution other than open in MS Excel and save as every day (not good enough!). In a 60,000 row externally-provided, daily-updated csv file, there's an error: CSV::MalformedCSVError: Illegal quoting in line 95. (as an example). I'm happy to skip/forget the malformed row (i.e. it has only 1/60000th importance). First attempt is to use CSV.foreach or similar, and
