            }).then((response) =>{          //这里使用了ES6的语法
                console.log(response)       //请求成功返回的数据
            }).catch((error) =>
                console.log(error)       //请求失败返回的数据
            })
        }
    }
</script>

Initiate multiple requests at the same time

function getUserAccount() {
  return axios.get('/user/12345');
}

function getUserPermissions() {
  return axios.get('/user/12345/permissions');
}

axios.all([getUserAccount(), getUserPermissions()])
  .then(axios.spread(function (acct, perms) {
    // Both requests are now complete
  }));
Copy after login
创建一个实例
你可以创建一个拥有通用配置的axios实例

axios.creat([config])
var instance = axios.create({
  baseURL: 'https://some-domain.com/api/',
  timeout: 1000,
  headers: {'X-Custom-Header': 'foobar'}
});
