1、uni.request({})

  1. uni.request({
  2.     url:'/api/getIndexCarousel.jsp',
  3.     method:'get',
  4.     success:res=>{
  5.         console.log(res.data);
  6.         this.carouselData = res.data
  7.     }
  8. })

2、uni.request({}).then()

  1. uni.request({
  2.     url:'/api/getIndexCarousel.jsp',
  3.     method:'get',
  4. }).then((result)=>{
  5.     let [error,res] = result;
  6.     //result将返回一个数组[error,{NativeData}]
  7.     //NativeData：调取接口后返回的原生数据
  8.     if(res.statusCode === 200){
  9.         this.carouselData = res.data
  10.     }
  11.     if(res.statusCode === 404){
  12.         console.log('请求的接口没有找到');
  13.     }
  14. })

3、async/await

  1. async：用在函数定义的前面
  2. async request(){    //函数体;}
  3. await：用在标明了async关键字的函数内部，异步操作的前面。
  1. onLoad() {
  2.     this.request();
  3. },
  4. methods: {
  5.     async request(){
  6.         let result = await uni.request({
  7.             url:'/api/getIndexCarousel.jsp'
  8.         })
  9.         console.log(result)
  10.         let [err,res] = result;
  11.         if(res.statusCode === 200){
  12.             this.carouselData = res.data;
  13.         }
  14.     }
  15. }
