问题 I have created 2 routes on my React-Redux app. I have added github applications settings with homepage and callback URL already. 1. When you hit this route : https://reduxapp.herokuapp.com/signin You click on Github login button, ==> githubGeturi 2.

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 由于JS单线程模型的原因，虽然可以通过异步来处理请求。但是最终还是需要由主线成处理出于希望将渲染 / (请求、计算) 解耦的想法，所以对现在由axios构建的api请求层做改造，所有的数据请求交予web-work处理。达到渲染与请求分开的目的问题同时存在多少个Worker比较合适？理论上worker没有上限，开启多少个都可以，根据实际情况即可。不建议按照CPU( navigator.hardwareConcurrency )核心数开启对应的数量像目前做的请求/渲染分离就是开启4个作为守护线程。因为除了IE6,7最少支持4个并发请求多个Worker如何协同工作？需要考虑开启多个worker的统一调配的问题，与负载均衡的问题。开启的worker可以通过数组存储负载均衡可以使用轮询，最有可用等算法来处理消息该如何处理？与axios不同的是，worker处理请求跨越不同的线程，真正的实现异步的请求。那如何保证正确的触发回调内部通过Promise构建，返回调用者Promise对象，同时为任务分配唯一ID。将任务ID, resolve，reject 同时存储记录 worker将返回数据/异常与接受到的任务ID一并打包返回通过任务ID将任务从任务池中pop出，执行对应的回调请求使用什么技术？

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言还在 mounted 里调用接口后再用 setOptions 来更新表单的 options 数组吗🤕？现在不需要这样了！使用 remote 属性，简单配置一下远端接口 url，即可自动发起请求并更新 options 属性🤛🏻！甚至，任何 props 都可以通过 remote 来远程获取😃，快来看看吧！场景你正在愉快地使用 el-form-renderer 来维护表单。 <template> <el-form-renderer :content="content" /> </template> <script> export default { data() { return { content: [ { id: 'name', type: 'input', label: '姓名', rules: [{required: true, message: '请输入姓名'}] } ] } } } </script> 所有表单相关的配置都写在一处，体验太棒了。此时，产品经理又提了个需求，你给表单加了一项 select。 <template> <el-form-renderer :content="content" /> </template> <script> export default { data(

These are the tested scenarios: Test an external API (fixer.io) with no headers <--- This works Test a local API server with headers <--- This does NOT work Test same local API with headers from node terminal <--- This works What could be the reason behind this behavior? And what is the solution? //This WORKS test('testing no headers', () => { return axios.get('http://api.fixer.io/latest') .then(

This string concatenation may be the issue as if I post this as AuthStr = 'Bearer 41839y750138-391' , the following GET request works and returns the data I'm after. axios.get(URL, { 'headers': { 'Authorization': AuthStr } }) .then((response => { console.log(response.data); }) .catch((error) => {

问题 This is a follow up question to the previous thread How to return json data to a react state? My react component makes an axios.post to an express server. The server uses web3 to sign a transaction onto Ethereum . Ethereum returns the following json object.
