我正在對 Azure Data Lake Storage 中的容器進行獲取 Blob 串列呼叫，其中包含 Blob 和目錄。
請求如下所示：
{
url: 'https://{account}.blob.core.windows.net/container-1?comp=list&restype=container&prefix=directory-1/&maxresults=100',
method: 'GET',
headers: {
'x-ms-date': 'Tue, 18 Jan 2022 05:58:28 GMT',
'x-ms-version': '2019-02-02',
Authorization: 'Bearer {Token}'
}
}
回應看起來像這樣：

這里有些結果是實際的 blob/檔案，而有些是目錄。 如何通過查看回應來區分目錄和檔案？
PS：最初我認為 application/octet-stream 的 content-type 將用于目錄和任何其他格式的 blob/files 但這也不起作用，因為所有 xlsx 檔案也具有 application/octet-stream 以回應 Azure Data Lake Storage。
完整的 NodeJS 代碼是：
const request = require('request')
const account = 'add your account here'
const strTime = new Date().toUTCString()
const containerName = 'container-1'
const BearerToken = 'Add your token here'
const options = {
url: `https://${account}.blob.core.windows.net/${containerName}?comp=list&restype=container&prefix=directory-1/&delimiter=`,
headers: {
Authorization: `Bearer ${BearerToken}`,
'x-ms-date': strTime, // var strTime = new Date().toUTCString();
'x-ms-version': '2019-02-02' // Stable xms version
}
}
function callback (error, response, body) {
if (error) console.log(error)
console.log(body)
}
request(options, callback)
uj5u.com熱心網友回復：
如評論中所述，您需要在delimiter=/請求中添加引數。所以你的請求會是這樣的：
https://{account}.blob.core.windows.net/container-1?comp=list&restype=container&prefix=directory-1/&maxresults=100&delimiter=/
當您請求包含引數時，您將看到回應中元素delimiter下回傳的虛擬檔案夾/目錄。BlobPrefix
請參閱此鏈接以了解有關 delimiter 引數的更多資訊：https ://docs.microsoft.com/en-us/rest/api/storageservices/list-blobs#remarks （“使用分隔符遍歷 Blob 命名空間”部分） .
