axios

Axios 是一个基于 promise 网络请求库，作用于node.js 和浏览器中。 它是 isomorphic 的(即同一套代码可以运行在浏览器和node.js中)。在服务端它使用原生 node.js http 模块, 而在客户端 (浏览端) 则使用 XMLHttpRequests。

get请求:

 <script>function register(){axios({method:'GET',url:'http://localhost:8080/java_web_final2_war_exploded/demo11'}).then(response => console.log(response),error => console.log(error))}</script>

post请求: 

axios.post('http://localhost:8080/java_web_final2_war_exploded/demo11', {firstName: 'Fred',lastName: 'Flintstone'}).then(function (response) {console.log(response);}).catch(function (error) {console.log(error);});

多并发:

function getUserAccount() {return axios.get('/user/12345');
}function getUserPermissions() {return axios.get('/user/12345/permissions');
}const [acct, perm] = await Promise.all([getUserAccount(), getUserPermissions()]);// ORPromise.all([getUserAccount(), getUserPermissions()]).then(function ([acct, perm]) {// ...});
