azure - CosmosDB模拟器: The value for one of the HTTP headers is not in the correct format

Question

我正在本地计算机上使用 Azure 存储模拟器编写/调试 Azure Function。不幸的是，我不太确定应该使用哪个 API 或存储的正确 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 存储模拟器正在运行，我可以在存储资源管理器中操作它。

谁能帮我弄清楚我做错了什么？我是否为此使用了“最佳”API？

Answer 1

根据您的代码，您希望使用 cosmosdb 来存储 StoredScore 数据。如果是这样，您应该使用您这边的 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:

1. Install and run CosmosDB emulator

2. 在本地创建一个包含集合的 Cosmos 数据库:

在本例中，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 key :

3.在VS本地创建一个http触发的Azure函数，这是我的代码:

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; }
    }

}

运行该函数并触发它，如果得到“201”作为响应，则您的数据已成功保存到本地 cosmos DB 中:

本地cosmos DB中的数据:

希望有帮助。
