Axios使用拦截器全局处理请求重试

不羁的心 提交于 2020-03-07 13:29:24
Axios拦截器 Axios提供了拦截器的接口,让我们能够全局处理请求和响应。Axios拦截器会在Promise的then和catch调用前拦截到。 请求拦截示例 axios.interceptors.request.use(function (config) { // 在发起请求请做一些业务处理 return config; }, function (error) { // 对请求失败做处理 return Promise.reject(error); }); 响应拦截示例 axios.interceptors.response.use(function (response) { // 对响应数据做处理 return response; }, function (error) { // 对响应错误做处理 return Promise.reject(error); }); Axios实现请求重试 在某些情况(如请求超时),我们可能会希望能够重新发起请求。这时可以在响应拦截器做下处理,对请求发起重试。 请求重试需要考虑三个因素: 重试条件 重试次数 重试时延 配置 axios.defaults.retry = 1; //重试次数 axios.defaults.retryDelay = 1000;//重试延时 axios.defaults.shouldRetry = (error) =>

Getting 401 Unauthorized error even when I'm logged in

问题 Posting this Q&A for whomever it might concern: I've been working on a practice project since this course with a react front-end. The user's page on the front end does not fetch any data and gives 401 Unauthorized error( message: You are not logged in! Please log in to get access) . I figured the cookies are not being sent with the get request, I've tried both axios and fetch requests. I could set the req.authorization = `Bearer ${token}` or req.cookies = ${cookies}` after locally storing

问题 I have a vue app that sits behind a firewall, which controls user authentication. The only way that I have of detecting when the user needs to re-authenticate is when the axios requests sent by my app receive a 403 error. When this happens the server also returns a web page, which I see as, error.response.data . This page asks the user to re-authenticate via an embedded form that, when completed, authenticates the user and sends back the output from my app's original request. My questions is

Handling an authentication page returned by an axios request in vue

问题 I have a vue app that sits behind a firewall, which controls authentication. When you first access the app you need to authenticate after which you can access the app and all is well until the authentication expires. From the point of view of my app I only know that the user needs to re-authenticate when I use axios to send off an API request and instead of the expected payload I receive a 403 error, which I catch with something like the following: import axios from 'axios' var api_url = '...

问题 Trying to figure out how to make an axios import and use in an Angular cli, base scaffolding. I didn't find any docs for this. I found this https://netbasal.com/angular-2-use-your-own-http-library-b45e51b3525e what he suggests does not apply. the Cli breaks on adding any of his code bits. Any insight on how to do a basic post api call in Angular? best I got is (the angular native approach) : import { Component } from '@angular/core'; import { Injectable } from '@angular/core'; import { Http }
