async await 同時發起多個異步請求的方法

    @action getBaseInfo = async() => {
        let baseInfo;
        try {
            baseInfo = await getBaseInfo(this.id);
            if (baseInfo) {
                this.baseInfo = baseInfo;
                // 發起請求後拿到 promise
                const visitedPromise = getVisitedCount(this.id);
                const subscribedPromise = getSubscribedCount(this.id);
                const connectionPromise = getConnection(this.id);
                // 等待 promise 返回再進行操做
                baseInfo.visitedCount = await visitedPromise;
                baseInfo.subscribedCount = await subscribedPromise;
                const connection = await connectionPromise;
                baseInfo.phoneNumber = connection.phoneNumber;
                baseInfo.email = connection.email;

                this.baseInfo = baseInfo;
            }
        } catch (e) {
            throwError(e);
        }
    };
    

多個請求的時候不使用 await，而是拿到請求的 promise，將 await 用在 promise 上，等待 promise 返回
