开发前端框架Vue初尝试

由 二次信任 提交于 2020-12-08 18:01:55
在当前的Web开发中，前后端分离的概念与好处显而易见。我想尝试下如何在前端展现一个springboot微服务返回的数据。我不打算使用模板引擎在后端完成数据绑定，那么就只有一条路可走了，在前端通过ajax技术来获取springboot微服务的数据，然后使用标准的前端技术来展现数据。 在前端开发中，当前流行的框架有三个：AngularJS, React与Vue。因为Vue是一个在美国的华人小伙开发的缘故，再加上Vue是独立于大公司平台的，因此获得了大众的推崇。 我看了几个Vue的教程Demo后，这项技术刷新了我对web前端开发技术的认知。兴奋之余，想自己动手做个demo来看看。对了我之前写了一个Springboot微服务JPADemo，这个微服务返回一个包含一条商品信息的json字符串。我们可以在浏览器上直接输入这个微服务的网址来查看返回的json字符串内容。不过这样太不友好了。我们可以写一个商品信息页面，然后将这个json包含的商品信息绑定到该页面的相应栏位上。 对于这个需求，我们需要做2件事情： 1. 设计呈现数据的html/css 2.使用ajax技术从后台获取数据并绑定到前端控件上。 我的html页面如下： <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>商品信息</title> <

Axios Post Works In Debug But Gives “Network Error” In Android Release Build

问题 I'm working on a React Native App. I'm using Axios to make api calls to server which is in PHP Laravel. If I run the app with the debug build everything works as expected. I can make calls to server with no problem. When I try the release apk, Axios always gives "Network Error" the status for which is 0. I've confirmed that I don't receive any request on the server aswell. But this only happens in Release apk. Im using local ip 192.168.0.112 on which the server is running on port 80. I've

react 中 Rap2的使用

谢谢 ， easymock 指望不上 第一步： 新建接口 会产生 接口 ID 第二步： 获取接口数据的方式， 将interfaceId 替换为 上面生成的接口ID 以获取单个接口数据为例： http://rap2api.taobao.org/app/mock/data/18123' 第三步：简单封装axios import axios from "axios"; import qs from "qs"; let http = { post: "", get: "", }; http.post = (api, data) => { let params = qs.stringify(data); return new Promise((resolve, reject) => { axios.post(api, params).then((res) => { resolve(res); }); }); }; http.get = (api, data) => { let params = qs.stringify(data); return new Promise((resolve, reject) => { axios.get(api, params).then((res) => { resolve(res); }); }); }; export default http; 第四步：

Axios not sending custom headers in request (possible CORS issue)

问题 I'm encountering a problem where axios doesn't seem to send custom headers with my requests. I'm using it like this: axios({ method: 'get', url: 'www.my-url.com', headers: { 'Custom-Header': 'my-custom-value' } }) However, looking at the actual request that is sent to the server, the custom header doesn't seem to be anywhere. REQUEST HEADERS: Accept: */* Accept-Encoding: gzip, deflate, br Accept-Language: es-ES,es;q=0.9 Access-Control-Request-Headers: custom-header Access-Control-Request

vue+vue-router+axios+element-ui构建vue实战项目之五（配置axios api接口调用）

由 十年热恋 提交于 2020-12-05 02:26:18
上一篇文章《 vue+vue-router+axios+element-ui构建vue实战项目之四（修改App.vue、router和page文件） 》中，我们重新配置了默认文件，使得项目能够正常运行。但是，项目仅仅是‘跑’起来了，没有涉及到ajax请求接口的内容。 vue本身是不支持ajax请求接口的，所以我们需要第三方工具。 一般使用较多的有vue-resource和axios，我以前学习的时候使用的是vue-resource，但是今天我们使用axios。 安装axios 首先，我们先安装axios工具，如下 1 npm install axios --save 好了，axios工具安装完成。 有关axios的更多内容，请移步： https://www.npmjs.com/package/axios ，中文资料请自行搜索。 调整main.js文件 调整后的代码，如下 1 import Vue from 'vue' 2 import App from './App' 3 import router from './router' 4 import axios from 'axios' 5 6 Vue.config.productionTip = false 7 // 全局注册axios 8 Vue.prototype.$http = axios 9 10 /* eslint
