c# - HttpClient、Azure 和 System.Net.Sockets.SocketException : what to do?

标签 c# azure httpclient .net-core-2.2

我们在 Azure 中的 Web 应用程序上遇到很多问题，该应用程序使用 HttpClient 对端点进行远程调用。

我意识到这是 Azure 中的出站连接限制的问题，因此我仅使用一个具有单例模式的 HttpClient 实例重构了代码。

这是我的 helper :

public class HttpClientHelper
{
    string ApiKey = "";
    static HttpClient httpClient;
    
    public HttpClientHelper(IConfiguration config)
    {            
        var appsettings = config.GetSection("AppSettings");
        ApiKey = appsettings.GetChildren().Where(x => x.Key == "URL").FirstOrDefault().Value;
        
        if (httpClient == null)
        {
            httpClient = new HttpClient();
            httpClient.DefaultRequestHeaders.Add("Authorization", ApiKey);
        }
    }

    public async Task<T> SingleRead<T>(string baseAddress, string url)
    {
        T returnValue = default(T);
        
        try
        {
            var response = await httpClient.GetAsync($"{baseAddress}/{url}").ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                var r = await response.Content.ReadAsStringAsync();
                returnValue = JsonConvert.DeserializeObject<T>(r);
            }
            else
            {
                Log($"SingleRead failed, error: {JsonConvert.SerializeObject(response)}");
            }
        }
        catch (Exception ex)
        {
            Log(ex, $"SingleRead ex: {baseAddress}/{url}");
            throw ex;
        }

        return returnValue;
    }

    public async Task<T> PostRead<T>(string baseAddress, string url, object entity = null)
    {
        T returnValue = default(T);            

        try
        {
            string json = JsonConvert.SerializeObject(entity);
            var body = new StringContent(json, UnicodeEncoding.UTF8, "application/json");
            var response = await httpClient.PostAsync($"{baseAddress}/{url}", body).ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                var r = await response.Content.ReadAsStringAsync();
                returnValue = JsonConvert.DeserializeObject<T>(r);
            }
            else
            {
                Log($"PostRead failed, error: {JsonConvert.SerializeObject(response)}");
            }
        }
        catch (Exception ex)
        {
            Log(ex, $"PostRead url: {baseAddress}/{url} entity: {JsonConvert.SerializeObject(entity)}");
            throw ex;
        }

        return returnValue;
    }
}

比我调用 SingleRead() (对于 GET)或 PostRead() (对于 POST)的基本请求。

问题是，有时我仍然会收到 SocketException:

我不明白问题出在哪里。 现在出站连接数低于服务计划(即“S3 : 2”)。

SNAT 似乎已经突破了限制:

enter image description here

出站连接也是如此:

enter image description here

(注意:昨天 21:30 我已将大小从 3 个实例调整为 2 个，这就是那些绿色“下降”的原因)。

我实在是搞不懂到底是怎么回事。环境设置相同。

有什么线索吗？

编辑 这是添加建议的 IHttpClientFactory 的版本(即编辑):

// Startup.cs
public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);            
    services.AddApplicationInsightsTelemetry(Configuration["APPINSIGHTS_CONNECTIONSTRING"]);
    services.AddHttpClient<MigrationHelper>();
}

public class MigrationHelper
{
    HttpClientHelper httpc;

    public MigrationHelper(IConfiguration config, HttpClient httpClient)
    {
        // ...
        
        httpc = new HttpClientHelper(config, httpClient);
    }
}

public class HttpClientHelper
{
    string ApiKey = "";
    HttpClient httpClient;
    
    public HttpClientHelper(IConfiguration config, HttpClient _httpClient)
    {
        var appsettings = config.GetSection("AppSettings");
        ApiKey = appsettings.GetChildren().Where(x => x.Key == "URL").FirstOrDefault().Value;
        
        httpClient = _httpClient;
        httpClient.DefaultRequestHeaders.Add("Authorization", ApiKey);
    }
    
    // ...
}

仍然不起作用，我收到了相同的错误套接字消息。这是一个完整的示例:

最佳答案

尝试 1:您在应用程序中最多可以使用 IHttpClientFactory 来实现弹性 HTTP 请求(请参阅:https://learn.microsoft.com/en-us/dotnet/architecture/microservices/implement-resilient-applications/use-httpclientfactory-to-implement-resilient-http-requests)。

尝试 2:当您横向扩展端点时(如果它在您的控制范围内)，所有实例上都会有一个负载均衡器，因此流量会在它们之间自动进行负载均衡。也许您需要更好的负载平衡解决方案(请参阅:https://learn.microsoft.com/en-us/azure/architecture/guide/technology-choices/load-balancing-overview)。

尝试 3:如果您的应用在单台计算机上运行得更好，您应该进行扩展并使用按应用扩展(请参阅:https://learn.microsoft.com/en-us/azure/app-service/manage-scale-per-app)

尝试 4:解决 Azure 应用服务中的间歇性出站连接错误(请参阅:https://learn.microsoft.com/en-us/azure/app-service/troubleshoot-intermittent-outbound-connection-errors)

P.S.:一个大胆的猜测是，端点无法处理来自 3 个实例的不断增加的请求(当使用通过 HttpClientHandler.MaxConnectionsPerServer 设置的 HttpClient 对象发出请求时，一个实例的并发连接数限制为 256 个(每个服务器端点)属性(property));这就是为什么当你减少实例数量时它会表现得更好
