This i a minimalistic example of the code I'm dealing with. path = "path to zipfile" from zipfile import ZipFile with ZipFile(path) as zf: try: print

问题 I have a WebForms website project in .Net 4.5 to which I have added ASP.Net Web API 2.2 NuGet package. The Web API methods are being called successfully and returning expected values. However, after I created a global exception handler class for Web API 2.2, and changed the controller class name from ProductController to Product to force the following error, then this error was not getting caught by global exception handler. Error Message when controller suffix is removed from Web API class

问题 long story short: I'm creating API that is supposed to be 100% REST. I'm trying to overwrite default response for the following case: I've got a method in my @RestController that has @RequestBody as an attribute @RequestMapping(value = {"register"}, method = RequestMethod.POST, produces = "application/hal+json") public Resource<User> registerClient(@RequestBody User user, HttpServletRequest request) and the method is working just fine if I send a proper request. But there is a problem when I

问题 I am having trouble with my custom book exception to interact with my program that creates a book object and for that too finally interact with my driver class Bookstore.java. My driver class doesn't catch the inconsistencies from happening. Like: title should not be blank or contain blanks only isbn should be a number between 1000 and 10000 (inclusive) quantity should not be negative (zero is ok, it means out of stock) When I run my driver class BookStore.java, it does not catch the above

问题 I have created nodejs + express application. Now in my application when exception caught errors are send as follows app.get('/data', (req, res) => { if(!req.params.token){ return res.status(403).send('Access token not provided'); } //do something here }); Instead of sending res.status(403).send('Access token not provided'); can I send something like this exception.js class Forbidden { constructor(message,stack = null){ this.code = 403; this.message = message this.stack = stack; } } app.js var

问题 Other than logging, what constitutes handling an exception? I ask as people say only catch an exception you can handle. For example, I wrote a tool to interact with Active Directory. I run it on the domain controller. As I have intimate knowledge of AD, an otherwise-exceptional case I can handle (eg I can raise a prompt to ask for another domain name) and go from there. But if there is a problem with the domain on a production server so critical , would this not be exceptional? So in this

问题 if (alMethSign[z].ToString().Contains(aClass.Namespace)) Here, I load an exe or dll and check its namespace. In some dlls, there is no namespace, so aclass.namespace is not present and it's throwing a NullReferenceException . I have to just avoid it and it should continue with rest of the code. If I use try-catch, it executes the catch part; I want it to continue with the rest of the code. 回答1: Is aClass a Type instance? If so - just check it for null: if (aClass != null && alMethSign[z]
