 # axiosdemo
 
-## Project setup
-```
-yarn install
-```
-
-### Compiles and hot-reloads for development
-```
+## yarn
+跟npm差不多的包管理器，感觉使用起来挺舒服的，所以推荐使用
+## 初始化项目
+yarn 
+## 运行
 yarn serve
+## 教程
+先安装axios `yarn add axios`，然后在main.js引入。
 ```
+import axios from 'axios'
+Vue.prototype.$axios = axios
+```
+## 使用
+在生命周期或者需要请求接口的位置
+```
+this.$axios.get("https://theluyuan.com/popArticles").then((res)=>{
+  console.log(res)
+})
+```
+可能会出现跨域问题，解决方法是后台允许跨域请求或者使用vuecli的代理服务器。
+后台配置之后继续使用以上网址，前台代理服务器请在`vue.config.js`写入
+```
+module.exports = {
+    devServer: {
+        proxy: {
+          '/api': {
+            target: 'https://theluyuan.com', //接口域名
+            ws: true,
+            changeOrigin: true
+          }
+        }
+      }
+}
+```
+设置前缀`/api`的请求转发到`https://theluyuan.com`
+```
+ this.$axios.get("/api/popArticles").then((res)=>{
+  console.log(res)
+})
+//实际请求地址就是 https://theluyuan.com/popArticles
+```
+这是基础使用，需要有些promise基础，其他问题清参考文档。链接 [axios-看云](https://www.kancloud.cn/yunye/axios/234845)。其他跟这些都是一样的了
 
-### Compiles and minifies for production
-```
-yarn build
-```
-
-### Lints and fixes files
-```
-yarn lint
-```
-
-### Customize configuration
-See [Configuration Reference](https://cli.vuejs.org/config/).
+promise基础可以参照阮一峰大大的[promise](https://es6.ruanyifeng.com/#docs/promise)或者[我的博客](https://theluyuan.com/blog/web-design/promise_1nd)
