promise.all方法合并请求接口的两个值

function promise1 = new Promise((resolve,reject)=>{

　　return result1

})

function promise2 = new Promise((resolve,reject)=>{

　　return result2

})

function promise = Promise.all([promise1(),promise2()]).then(

let tree = [...result1];

tree.push(result2)

).catch()

//调promise方法

promise();
