问题 I'm using Nuxt and axios-module. I trying to global error handling by axios global interceptor. How Can I use error function in Nuxt Plugin? // ~/plugins/axios.js export default function ({ $axios, store, redirect, error }) { $axios .onError(apiError => { error({statusCode: '403', message: 'test'}) // It's not work. redirect('http://google.com') // It's work. }) } redirect is working. but error not work. just display server error page. 回答1: Your plugin function should return a promise and

问题 Answer to question about error handling with lapply always return NA or NULL when an element fails, i.e. myfun <- function(s) { tryCatch(doSomething(s), error = function(e) { return(NULL) } } However, this is not general enough since doSomething(s) may return NULL or NA itself. Therefore, ideally I want myfun written so that after lapply(mylist, myfun) I can somehow get all the indices of failed elements. How to do this? 回答1: Catch and release the error by handing it with identity() res =

问题 In my programmer's experience, I have mixed error handling all the ways possible... I have created my personal style. However, I'd like to hear what you consider to be the pro and cons of error handling at the beginning vs at the end of the method. Handling at the beginning: public String GenerateSomeStringData(String data, int value) { if (data == null) throw new ArgumentNullException("data"); if (value <= 0) throw new ArgumentException("value must be greater than zero"); int dataValue; if (

问题 Is it possible to execute certain commands in case of error when using tryCatch in R ? I am using the code below but it does not execute X = alternative_value tryCatch( { X = certain_function_that_sometimes_returns_error }, error=function(e) { X = alternative_value }) 回答1: Assign your tryCatch directly to x foo <- function() stop("hello") bar <- function() 'world' x <- tryCatch( { foo() }, error = function(e){ bar() } ) x # [1] "world" 来源： https://stackoverflow.com/questions/43380908/trycatch

问题 I'm trying to implement a simple interpreter in Rust, for which I have created a Tokens struct, which takes source characters and produces either a Token or a ScanError inside a Result : pub struct Tokens<'src> { chars: Chars<'src>, } impl<'src> Iterator for Tokens<'src> { type Item = Result<Token, ScanError>; fn next(&mut self) -> Option<Result<Token, ScanError>> { // ... } } Since Result implements FromIterator , it is simple to collect the result to either the first ScanError or a vector

问题 Angular2 has very useful promises error catching mechanism for chained promises. Yet, the usual case (at least for me) is that of promises called from within the resolve handler of the previous one. This is due to the need to process information prior to starting the next promise. For example: this.d( "facebookOAuthLogin() - starts" ); this.fbProvider.login().then( ( loginResponse: { status: string, authResponse: any, accessToken: string, expiresIn: string, session_key: string, sig: string,
