异步接口请求中获取返回值
详情
ts
// 让本文件被定义为一个模块 允许使用顶层await
export {};
/** 等待函数 固定耗时 以便模拟异步接口请求 */
function wait() {
return new Promise((resolve) => {
setTimeout(() => {
resolve(void 0);
}, 1000);
});
}
/** 一个异步函数 */
function asyncFun(query: string = "你是笨猪，哈哈哈哈") {
const response = {
data: {
info: query,
},
msg: "success",
code: 200,
};
type Response = typeof response;
return new Promise<Response>(async (resolve) => {
await wait();
resolve(response);
});
}
/** 一个具体的对象 */
// @ts-ignore
const formState = await asyncFun().then((res) => {
return res.data;
});
console.log(" formState ", formState);贡献者
