使用promise方式来获取网络数据

    let data = [];

    new Promise(function(resolve,reject){
        axios.post(‘api.php‘).then(function(response){
            resolve(response);
        },function(error){
            reject({data:[]});
        });
    }).then(function(resolve){
        console.log(‘数据来了‘);
        console.log(resolve.data);
        data = resolve.data;
    },function(reject){
        console.log(reject);
        data = reject.data;
    });
