部署到azure后,documentclient不工作

我正在开发一个poc(在.net内核中),使用azure documentclient向本地cosmos db模拟器写入一些数据。

private string _endpointUri = String.Empty;
private string _primaryKey = String.Empty;
private DocumentClient _client;
private string _databaseName = String.Empty;
private string _collectionName = String.Empty;

public CosmosDBStorage(IConfiguration configuration)
{
    _endpointUri = configuration["CosmosDBEndpointUri"];
    _primaryKey = configuration["CosmosDBPrimaryKey"];
    _client = new DocumentClient(new Uri(_endpointUri), _primaryKey);
    _databaseName = configuration["CosmosDBName"];
    _collectionName = configuration["CosmosDBCollectionName"];
}

public async Task WriteAsync(dynamic data)
{
    try
    {
        await this._client.CreateDocumentAsync(UriFactory.CreateDocumentCollectionUri(_databaseName, _collectionName), data);
    }
    catch
    {
        throw;
    }
}

不过,在我的本地应用程序中运行良好,在将应用程序部署到azure之后,我正尝试使用同一个本地cosmos db模拟器进行测试。它失败了,错误如下。

你知道会有什么问题吗?

更新:

添加了内部异常详细信息。

不能使用本地模拟器在azure中进行测试。azure找不到你的 localhost 因为它超出了网络的界限。

它将在自己的网络中搜索并失败。你需要指向一个实际的cosmosdb实例,或者以某种方式将你的模拟器从服务器或你的pc公开到azure应用服务。

请记住,cosmosdb仿真器只用于本地开发,不用于其他用途。它被认为是模仿行为而不是真实的东西。

建议的方法是创建一个cosmosdb帐户并使用该连接字符串。
