Azure存储模拟器：HTTP标头之一的值格式不正确

• 问答

我正在使用本地计算机上的Azure存储模拟器编写/调试Azure函数。不幸的是，我不确定应该使用哪个API或用于存储的正确URL。我的代码如下：

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

该函数的输入是：

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Storage Explorer中对其进行操作。

有人可以帮助我弄清楚我做错了什么吗？我是否为此使用了“最佳” API？

根据您的代码，您想使用cosmosdb存储StoredScore数据。如果是这样，则应使用CosmosDB仿真器而不是存储仿真器。

请按照以下步骤使您的代码正常工作：

  1. Install and run CosmosDB emulator

  2. 使用您的本地计算机上的集合创建一个cosmos数据库：

enter image description here

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

您可以在此处找到您的cosmosdb主机和密钥： enter image description here

3。在VS中本地创建一个HTTP触发的Azure函数，这是我的以下代码：

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，如果响应为“ 201”，则您的数据已成功保存到本地cosmos DB中： enter image description here

本地cosmos DB中的数据： enter image description here

希望有帮助。
