/** get 请求 * @param {接口地址} url * @param {请求参数} params */ get(url,params){ return new Promise((resolve,reject) => { wx.request({ url:url, data:params, success(res){ resolve(res.data); }, fail(err){ reject(err); } }) }) } /** post 请求 * @param {接口地址} url * @param {请求参数} params */ post(url,params){ return new Promise((resolve,reject) => { wx.request({ url:url, type:‘POST‘, data:params, success(res){ resolve(res.data); }, fail(err){ reject(err); } }) }) }
上面是代码封装
//调用
async getData(){
let url = this.testUrl+‘main/scpz/searchGs.php‘;
this.isShow = ‘‘;
let param = {
gsmc:this.gsmc,
action:‘query‘
}
let res = await this.get(url,param);
let data = res.data;
if(data){
console.log(data)
this.searchData=data;
this.hasData = ‘1‘;
this.$apply();
}else{
this.hasData = ‘2‘;
this.$apply();
}
}
如果多重的话
//先封装一下
function delay(word){
return new Promise((reslove,reject)=>{
setTimeout(()=>{
reslove(‘hello‘ +word)
},2000)
})
}
// async+await一起使用
async function start(){
const word1 = await delay(‘1111‘)
console.log(word1)
const word2 = await delay(‘2222‘)
console.log(word2)
const word3 = await delay(‘3333‘)
console.log(word3)
}
start()
