我正在使用.NET SDK Microsoft.Azure.DocumentDB 在Azure上与cosmos db合作。我的网络无法连接到cosmos db(代理、网络…)时遇到问题

例子:

   this.client = new DocumentClient(new Uri(EndpointUrl), PrimaryKey, new ConnectionPolicy {
            ConnectionMode = ConnectionMode.Direct, ConnectionProtocol = Protocol.Tcp,
            RetryOptions = new RetryOptions {MaxRetryAttemptsOnThrottledRequests = 5, 
            MaxRetryWaitTimeInSeconds= 5 },
            RequestTimeout = new TimeSpan(1000)});
var a = await this.client.CreateDatabaseIfNotExistsAsync(new Database { Id = "FamilyDB" });

我的应用程序循环永远保持一致 CreateDatabaseIfNotExistsAsync 以及消息:

Endpoint not reachable. Refresh cache and retry
Failover happening. retryCount 6
RefreshLocationAsync() refreshing locations
An error occurred while sending the request. ---> System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.
Endpoint not reachable. Refresh cache and retry
Failover happening. retryCount 7
RefreshLocationAsync() refreshing locations
An error occurred while sending the request. ---> System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.
....

我不能停下来或试着抓住它,我试着 requestoption requestTimeout 但它不起作用。

你可以用这个方法 OpenAsync() 在 documentClient 已成功初始化。

它将为 End Point not reachable 以及 Invalid Authorization Key

DocumentClient documentClient = new DocumentClient(new Uri(endPointUri), authKey);

try
    {
        await documentClient.OpenAsync();
    }

catch(Exception ex)
    {
        // Handle Exception Here
    }

您可以继续查询成功初始化的 DocumentClient
