react-native fetch async/await response filtering

Question

我有来自我的服务器的响应buildings : [record1, record2, ...],我想只得到该响应的数组.我怎样才能从Promise获得数组？我尝试了一些异步/等待的东西,但我不明白如何在这段代码中使用它:

setupImpagination() {
    ....
    fetch(pageOffset, pageSize, stats) {
        return fetch(`http://localhost:3000/api/building/all?skip=${pageOffset}&limit=${pageSize}`)
            .then(response => {
            console.log('response.json() => ',response.json());
            response.json()
            })
            .catch((error) => {
            console.error(error);
            });

    }
    });
}

然后

 fetch(pageOffset, pageSize, stats) {
        return fetch(`http://localhost:3000/api/building/all?skip=${pageOffset}&limit=${pageSize}`)
            .then(response => {
               console.log('response.json() => ',response.json());
               response.json()
            }).then(responseJson => {
               return responseJson.buildings
            }).catch((error) => {
               console.error(error);
            });

        }
    });

异步/等待方式:

 fetch(pageOffset, pageSize, stats) {
       try {
           const response = await fetch(`http://localhost:3000/api/building/all?skip=${pageOffset}&limit=${pageSize}`);
           const responseJson = await response.json();
           return responseJson.buildings;
       } catch(error){
            console.error(error);
       }
