在PowerShell的Powershell查詢上獲得404 DB

Question

我在此鏈接的下載中使用此腳本。 https://gallery.technet.microsoft.com/scriptcenter/How-to-query-Azure-Cosmos-0a9aa517 但是由於某種原因，我得到了404響應。

我直接拷貝了數據庫的url。放入一個假的URL給我一個「無法解決」的錯誤，所以我知道該位置存在。

基於Azure的CosmosDB API文檔在這裏： https://docs.microsoft.com/en-us/rest/api/documentdb/databases 的$ databaseID是用戶設置的，只是必須是唯一的，所以我將它設置爲相同的數據庫名稱，並分配了到url 。

將它改爲不同的仍然給我同樣的404響應消息（如下）。

Answer 1

我注意到，你在兩個地方使用$DatabaseId：

$ResourceLink = "dbs/$DatabaseId/colls/$CollectionId" 

和

$CosmosDBEndPoint = "https://$DatabaseId.documents.azure.com:443/" 

如果$DatabaseId指的是您的帳戶名，那麼你就需要改變你的$ResourceLink變量和使用的數據庫的名稱包含收集您的帳戶內。但是，如果$DatabaseId引用數據庫名稱，那麼您需要更改$CosmosDBEndPoint並在那裏使用帳戶名稱。
