如何处理异步调用

  //用户注册
    async uerRegister({commit},user){
        let result=await reqUserRegister(user);
             console.log(result)
            if (result.code==200) {
                return 'ok'
            } else {
                return Promise.reject(new Error('fail'));
            }
        }

 //用户注册
      async userRegister(){
       const {phone,code,password,password1} =this;

       try {
        //如果成功路由跳转
        password==password1 && phone &&code&&await this.$store.dispatch('uerRegister',{phone,code,password})
        this.$router.push('/login')
       } catch (error) {
        
        alert(error.message)
       }
      
      
      }
