interceptor

问题 I've created axios interceptor which is responsible for adding token before every request is send to my rest API. import axios from 'axios'; import { store } from '../store/store'; export default function execute() { axios.interceptors.request.use(function(config) { const token = store.state.token; if(token) { config.headers.Authorization = `Bearer ${token}`; console.log(config); return config; } else { console.log('There is not token yet...'); return config; } }, function(err) { return

问题 I want to intercept each request and error responses. I already can intercept requests and set a token in the headers and I can intercept the responses to handle a refresh token. However I can't find a way to intercept HttpErrorResponse . I tried 2 methods. One with an explicit rxjs catchError and the other with some kind of callback: intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { const authToken = this.auth.getToken(); if (authToken) { req = req.clone({

问题 I have HttpInterceptor : import {HttpErrorResponse, HttpEvent, HttpHandler, HttpInterceptor, HttpRequest} from '@angular/common/http'; import {AuthService} from '../service/auth.service'; import {Observable} from 'rxjs/Observable'; import {Injectable} from '@angular/core'; import {Router} from '@angular/router'; @Injectable() export class AuthInterceptor implements HttpInterceptor { constructor(private authService: AuthService, private router: Router) { } intercept(request: HttpRequest<any>,

问题 I created a resttemplate in my spring boot application like this: @Configuration public class MyConfiguration { @LoadBalanced @Bean RestTemplate restTemplate() { return new RestTemplate(); } } This works fine in all classes when autowired. However, in my interceptor, this throws up nullpointer exception. What could be the reason and how can I configure a loadbalanced (using Ribbon) resttemplate in my interceptor? Update: my interceptor: public class MyInterceptor implements

问题 I need to implemented something like a filter or listener, that intercepts HTTP requests and retrieves the HTTP headers for various purposes. I use Java, Jboss application server and web services. I want this filtering system to be performed prior to the Web Services call - was thinking about aspects but they do not hold the HTTP related stuff. After the filter, the service call should be carried out. Jax-WS handlers don't work for me either as they only hold the SOAP payload. Any ideas?

问题 I'm doing my project in angularjs how can i add one common loader or progress bar to entire project with css rather than calling show/hide block functions for every controller's div class. 回答1: You have to write an interceptor to do that. To learn about interceptor refer: https://docs.angularjs.org/api/ng/service/$http But someone has already done all the works, so why re-invent the wheel! http://chieffancypants.github.io/angular-loading-bar/ 回答2: Until you get the response you can put a

问题 I do some operation of Struts2's value stack in an interceptor,code like this: public String intercept(ActionInvocation actionInvocation) throws Exception { String invokeRes = actionInvocation.invoke(); ValueStack valueStack = actionInvocation.getStack(); List<Object> shouldCheckFieldValues = Lists.newArrayList(); List<String> keywords = Lists.newArrayList("哈哈", "头部", "测试"); RegexKeywordFilter filter = new RegexKeywordFilter(); filter.add(keywords); filter.compile(); final ReplaceStrategy
