Azure 存储模拟器：HTTP headers 之一的值格式不正确

Question

我是 writing/debugging Azure Functions，在我的本地计算机上使用 Azure 存储模拟器。不幸的是，我不太确定应该使用哪个 API(s) 或正确的存储 URL。我的代码如下所示：

CosmosClient client = new CosmosClient(storageURL, authKeyString);
Database db = client.GetDatabase("devstoreaccount1");
container = db.GetContainer("leaderboard");
ItemResponse<StoredScore> resp = await container.CreateItemAsync<StoredScore>(newScore);

函数的输入是：

storageURL = "http://127.0.0.1:10002"
authKeyString = "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=="

在上面代码的最后一行，我得到一个异常：

Azure 存储模拟器运行我可以在存储资源管理器中操作它。

谁能帮我找出我做错了什么？我为此使用 'best' API 吗？

Answer 1

根据您的代码，您希望使用 cosmosdb 来存储您的 StoredScore 数据。如果是这样，您应该使用您身边的 CosmosDB 模拟器而不是存储模拟器。

请按照以下步骤使您的代码正常工作：

Install and run CosmosDB emulator
在本地创建一个带有集合的 cosmos 数据库：

在这种情况下，我的 cosmos 数据库名称是 localdb，我的容器名称是 localcontainer

您可以在此处找到您的 cosmosdb 主机和密钥：

3.Create 本地 VS 中的 http 触发 Azure 函数，这是我下面的代码：

using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using Microsoft.Azure.Cosmos;

namespace cosmostest
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            CosmosClient client = new CosmosClient("https://localhost:8081/", "<your key here>");
            Database db = client.GetDatabase("<your local db name>");
            Container container = db.GetContainer("<your local container name>");
            var newScore = new StoredScore() { id ="1", name ="stan", score =100 };
            ItemResponse<StoredScore> resp = await container.CreateItemAsync<StoredScore>(newScore);
            return new OkObjectResult(resp.StatusCode);
        }
    }

    public class StoredScore
    {

        public string id { get; set; }
        public string name { get; set; }
        public int score { get; set; }
    }

}

运行函数并触发它，如果你得到“201”作为响应，你的数据已经成功保存到你本地的 cosmos DB 中：

本地cosmos DB中的数据：

希望对您有所帮助。
