问题 I'm defining a custom Exception on a model in rails as kind of a wrapper Exception: ( begin[code]rescue[raise custom exception]end ) When I raise the Exception, I'd like to pass it some info about a) the instance of the model whose internal functions raise the error, and b) the error that was caught. This is going on an automated import method of a model that gets populated by POST request to from foreign datasource. tldr; How can one pass arguments to an Exception, given that you define the

问题 I have not yet been able to find a list of all the built-in Exception sub classes in PHP. I'd rather use built in ones when they make sense, before creating my own exception subclasses. For example, I know InvalidArgumentException exists, but there appears to be nothing comparable to Java's NullPointerException. Does anyone have or can link to a list of the available Exception subclasses in PHP? 回答1: PHP 5 has two built in exceptions Exception ErrorException Libraries within PHP have their

问题 I have look at one of the perfect article on Exception handling in ASP.NET MVC and want to implement a method as on Method 6 in this article in order to reuse the same error page for all of other modal dialogs on error and exception situations. On the other hand, as I use popup window, I need to render a PartialView in my modal dialog instead of redirecting the page. Is it possible to do this?

问题 I am using tryCatch to catch any errors that occur. However, even though I catch them and return the appropriate error value, it looks like the error is still reported in the logs of my batch system. Is there a way to completely suppress the error and simply proceed with the error handling I provide? 回答1: Make sure you're neither (1) returning an error, nor (2) printing to stderr in your error handling code. Note one gotcha here is message sends its output to stderr . A minimal way to

问题 I'm new to the concept of middleware, and am currently struggling with the proper way to handle exceptions in my MVC Core project. What I want to happen is for the Exception to be caught, logged, and then send the user to a friendly error page with a message. At first, I was trying to manage all of these within the middleware, but realized I probably wasn't doing it correctly. So if I want this flow to happen, should I use both my Exception-logging middleware AND the app.UseExceptionHandler("
