如何使用 JAVA 从 Azure 的 Cosmos DB 集合之一中获取所有文档？

Question

I gone through the documentation , there are two ways to fetch the documents

1. using Azure's Endpoint https://{databaseaccount}.documents.azure.com/dbs/{db-id}/colls/{coll-id}/docs even i set the required headers Token and all I am getting some exception

{ "code": "Forbidden", "message": "Sql api is not supported for this database account\\r\\nActivityId: fc5ec296-b7a1- 44df-9c69-42e804177242, Microsoft.Azure.Documents.Common/2.7.0" }

2. using SDK through the sdk also im getting the same above exception , below is the java code which im using for fetching the documents

   public class App { private static final String END_POINT = "https://***.documents.azure.com/"; private static final String MASTER_KEY = "***"; // Define an id for your database and collection private static final String DATABASE_ID = "iotdata"; private static final String COLLECTION_ID = "details"; public static void main(String[] args) { DocumentClient documentClient = new DocumentClient(END_POINT, MASTER_KEY, new ConnectionPolicy(), ConsistencyLevel.Session); System.out.println("Check if database " + DATABASE_ID + " exists."); String databaseLink = String.format("/dbs/%s", DATABASE_ID); try { ResourceResponse<Database> readDatabase = documentClient.readDatabase(databaseLink, null); if (readDatabase.getStatusCode() == 200) { System.out.println("Connection Established"); } FeedResponse<Document> queryResults = documentClient.queryDocuments("/dbs/iotdata/colls/details", "SELECT * FROM details WHERE mac_address = '28:b2:bd:01:d0:94'", null); System.out.println("Running SQL query..."); for (Document family : queryResults.getQueryIterable()) { System.out.println(String.format("\\tRead %s", family)); } } catch (Exception e) { e.printStackTrace(); } }

   }

Firstly,i have to say that your sample code in second point is totally right.I tested it and works with Cosmos DB Sql Api.

According to the error:

Sql api is not supported for this database account

It seems that you want to access cosmos db account of other type(maybe mongo api i guess) with SQL API REST API or SQL API SDK. That's forbidden and i'm afraid that's the reason for above error.If your Cosmos DB account is using the Mongo API, you should be using tools and drivers that use the Mongo API. Please refer to this case: Sql api is not supported for this database Error
