/** 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()
