Angular的同步:Promise

Angular的同步方法

方式有很多,我记录的是Promise和async+await的方法:

1:async+await:

//测试同步方法,用async和await关键字

async callRPATest(){

let result =await this.generateRPATest();

console.log("result:"+result);

}

generateRPATest(){

let url=this.baseURL+"generateRPATest"

return this.http.post(url,{}).toPromise();

}

2:Promise的then:

getdata(){
  this.http.get("localhost:8800/test/fun")
  .toPromise().then(data=>{
    console.log(data)
  }).catch(err =>{
    alert(err);
  })
}
