使用拦截器延迟所有请求 [英] Delay all requests with interceptor

问题描述

出于调试目的，我想延迟所有请求，以便可以模拟加载资源实际上需要时间.我想这可以在拦截器中完成.

For debugging purposes I want to delay all requests so that I can simulate that it actually takes time to load resources. I guess that this can be done in a interceptor somehow.

我确实设法通过以下方式延迟了单个请求:

I do manage to delay single requests now with:

const delay =
    milliseconds =>
      new Promise(resolve =>
        setTimeout(resolve, milliseconds));

delay(1000)
  .then(() => {
    axios.post(
      ...
    ).then((response) => {
      ...
    });
  });

但是我会很乐意在一处处理所有请求.

But I would be more nice to do it for all requests at one place.

推荐答案

抱歉，回复晚了，但是我遇到了类似的问题.我想对几乎所有请求都使用人为延迟，以提高可用性和调试目的.我创建了一个新服务(位于src/services/HttpClient.js)并使用了全局请求拦截器:

Sorry for the late response, but I've had a similar issue. I'd like to use an artificial delay for almost all requests to improve usability and for debugging purposes too. I've created a new service (situated at src/services/HttpClient.js) and use a global request interceptor:

import axios from 'axios';

// Create a new instance.
const service = axios.create({
  baseURL: process.env.API_ENDPOINT,
  delayed: true  // use this custom option to allow overrides
});

service.interceptors.request.use((config) =>
  if (config.delayed) {
    return new Promise(resolve => setTimeout(() => resolve(config), 600));
  }
  return config;
});

export default service;

自定义配置选项delayed可用于覆盖全局行为.以下请求将立即执行:

The custom config option delayed can be used to override the global behavior. The following request will be performed without a delay:

import $http from '@/services/HttpClient';

$http.get('/example-url', {
  delayed: false
}).then((response) {
  …
});

后台请求不会延迟我的应用程序.但是，由用户的操作触发的所有请求都使用延迟.

Requests in the background don't use a delay in my app. But all requests triggered by an action by the user use the delay.
