如何防止HttpClientHandler上的套接字耗尽

时间：2019-05-22 14:17:17

标签： c# .net azure httpclient azure-functions

与Microsoft.Azure.Management命名空间中的其他客户端（即SubscriptionClient）不同，OperationalInsightsManagementClient在构造函数中不将HttpClient作为参数。这意味着我不能将HttpClientFactory与依赖项注入一起使用来以正常方式防止套接字耗尽。

（我使用https://github.com/tpeczek/HttpClientFactory.Azure.Functions来实现httpclientfactory）

我正在使用Azure持久函数，扇出了100多个函数，每个函数都创建了此客户端，导致出现以下错误，我认为是由上述问题引起的。订阅ID通常是不同的或动态的，因此我无法重用一个OperationalInsightsManagementClient。

OperationalInsightsManagementClient确实在构造函数中使用了HttpClientHandler，但是假设这是我的问题，如何正确设置，像HttpClient一样共享和管理它以防止套接字问题。

到目前为止，这些功能在我的本地计算机上都可以正常工作，这在部署到云中时似乎是一个问题。

示例代码：

using Microsoft.Azure.Management.OperationalInsights;

....
operationalInsightsManagementClient = new OperationalInsightsManagementClient(myToken);

operationalInsightsDataClient.WorkspaceId = workspaceId;

try
{
    var response = await operationalInsightsDataClient.QueryAsync(query);
    output = response?.Results;
}
catch (Exception e)
{
...
