Fetch image in React from Node.js request

由 帅比萌擦擦* 提交于 2021-02-19 08:56:14
问题 When needed, React asks for an image using Superagent : exports.getImgFromSection=function(id,request){ request .get('/img/'+id) .end((error, response) => { if (!error && response) { console.log(response.file); } else { console.log('There was an error fetching server', error); } }) } Node.js answers this way : app.get("/img/:id",function(req, res){ // check if exists and then res.sendFile(path.join(__dirname, './data/img/'+req.params['id']+'.png')); }); But I don't know how to get the image

React Swiper with Dynamic Content

由 三世轮回 提交于 2021-02-19 02:04:25
问题 I'm making a carousel with images from Instagram using react-id-swiper. The Swiper component doesn't seem to be updating after the response. I thought that putting my setState inside componentWillMount would work but apparently not. When I open the inspector in Chrome it starts working? import React, { Component } from 'react' import Swiper from 'react-id-swiper' import request from 'superagent' import './index.css' const swiperParams = { slidesPerView: 5, spaceBetween: 0, navigation: {

Is there a way to overcome lag between changes in OneNote client and API results?

由 懵懂的女人 提交于 2021-02-08 09:25:14
问题 Changes in OneNote client aren't immediately reflected in apigee. For example: Renaming a section in OneNote client. Apigee shows the old name. Adding a section and adding notes to that section in OneNote; these aren't reflected in my app that uses the API. As seen below: Is this a API call caching issue or a known OneNote issue? Whats the recommended way to resolve it? I'm using Superagent and wondering if its no-cache plugin would resolve this. 回答1: If you add the following header to an API

Extending SuperTest

问题 I like to use SuperTest to work with my auth system like this: const request = require('./valid_access_token')(require('supertest')); request(app) .get('/v1/bots') .valid_token() .expect('Content-Type', /json/) ... valid_token() would insert a valid access-token module.exports = function (Request) { const Token = require('../../../app/v1/models/loader')('token'); const UserFactory = require('../fixtures/user'); Request.prototype.valid_token = function() { return UserFactory.createAsync('user'

keep-alive connection with Superagent

由 余生长醉 提交于 2020-12-29 13:19:28
问题 I'm running a node.js server A which uses superagent to issue HTTP requests to another server B. I investigated the request on server B and saw the the header connection being close and the httpVersion being 1.1 : var http = require('http'); var request = require('superagent'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.write('req.httpVersion seen on server:' + req.httpVersion); res.write('\nreq.headers.connection seen on server:' + req

Uncaught Error: A cross-origin error was thrown. React doesn't have access to the actual error object in development

问题 Everytime I submit a zone, It display this error 'Uncaught Error: A cross-origin error was thrown. React doesn't have access to the actual error object in development' It only occurs when I press on the submit zone button which I guess is happening when the old states are being changed to the new one. (this.setState) CreateZone.js import React, { Component } from 'react' export default class CreateZone extends Component { constructor(props){ super(props) this.state = { zone: { name: '',

The summer is coming ” 我知道，那些夏天，就像青春一样回不来。 - 宋冬野 青春是回不来了，倒是要准备渡过在西安的第三个夏天了。 废话 我发现，自己对 coding 这件事的称呼，从 敲代码 改为 写代码 了。 emmm....敲代码，自我感觉，就像是，习惯了用 const 定义常量的我看到别人用 var 定义的常量。 对，优雅！ 写代码 这三个字，显得更为优雅一些，更像是在创作，打磨一件精致的作品。 改编自 掘金站长 的一句话： ” 子非猿，安之 coding 之乐也。 看完本文的收获 ctrl + c ctrl + v nodejs 入门级爬虫 为何写爬虫相关的文章 最近访问 艾特网 的时候发现请求有点慢。 后来经过一番检查，发现首页中搜索热点需要每次去爬取百度热搜的数据并当做接口返回给前端，由于是服务端渲染，接口堵塞就容易出现访问较慢的情况。 就想着对这个接口进行一次重构。 解决方案 设置定时任务，每隔 1分钟/3分钟/5分钟 爬取新浪微博实时热搜(新浪微博热搜点击率更高一些) 爬取到数据后不直接返回给前端，先写入一个 .json 格式的文件。 服务端渲染的后台接口请求并返回给前端 json 文件的内容 需求捋清楚以后就可以开干了。 创建工程 初始化 首先得找到目标站点，如下：(微博实时热搜) s.weibo.com/top/summary… 创建文件夹

前言 周末自己在家闲着没事，刷着微信，玩着手机，发现自己的微信头像该换了，就去网上找了一下头像，看着图片，自己就想着作为一个码农，可以把这些图片都爬取下来做成一个微信小程序，说干就干，了解一下基本都知道怎么做了，整理分享一波给大家。 目录 安装node，并下载依赖 搭建服务 请求我们要爬取的页面，返回json 安装node 我们开始安装node，可以去node官网下载 https://nodejs.org/zh-cn/ ，下载完成后运行node使用， node -v 安装成功后会出现你所安装的版本号。 接下来我们使用node, 打印出hello world，新建一个名为index.js文件输入 console.log('hello world') 运行这个文件 node index.js 就会在控制面板上输出hello world 搭建服务器 新建一个·名为node的文件夹。 首先你需要下载express依赖 npm install express 再新建一个名为demo.js的文件 目录结构如图： 在demo.js引入下载的express const express = require('express'); const app = express(); app.get('/index', function(req, res) { res.end('111') }) var
