Cosmos DB对Azure函数的模拟

Question

不管怎样，我正在做的一个项目就是使用CosmosDB。他们已经创建了一些azure函数来插入和从Cosmos DB获取数据。我必须通过模拟本地机器中的Cosmos DB来测试这些功能。

我如何测试这些方法？如何在我的本地机器中模拟宇宙数据库？

由于您已经安装了Cosmos DB模拟器，您可以在本地使用SDK或直接在data explorer上操作Cosmos DB中的文档。

插入文档代码示例：

using Microsoft.Azure.Documents;
using Microsoft.Azure.Documents.Client;
using System;
using System.Threading.Tasks;

namespace JayGongDocumentDB.module
{
    class TestEmulator
    {
        private static readonly string endpointUrl = "https://localhost:8081";
        private static readonly string authorizationKey = "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==";
        private static readonly string databaseId = "db";
        private static readonly string collectionId = "coll";

        private static DocumentClient client;

        public static async Task TestAsync()

        {
            client = new DocumentClient(new Uri(endpointUrl), authorizationKey);
            var uri = UriFactory.CreateDocumentCollectionUri(databaseId, collectionId);

            var doc = new Document();
            doc.SetPropertyValue("name", "jay");

            await client.CreateDocumentAsync (
                "/dbs/db/colls/coll", doc,null);
            Console.WriteLine("insert success");

        }
    }
}

您可以在azure cosmos db模拟器中找到endpointURL和键：

using System.Collections.Generic;
using Microsoft.Azure.Documents;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;

namespace TestAzureFunction
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static void Run([CosmosDBTrigger(
            databaseName: "db",
            collectionName: "coll",
            ConnectionStringSetting = "CosmosdbString",
            LeaseCollectionName = "leases")]IReadOnlyList<Document> input, TraceWriter log)
        {
            if (input != null && input.Count > 0)
            {
                log.Verbose("Documents modified " + input.Count);
                log.Verbose("First document Id " + input[0].Id);
            }
        }
    }
}
