HttpClientFactory内存泄漏 [英] HttpClientFactory Memory Leak

问题描述

在我的c＃控制台应用程序（.net 4.6.1）中，我需要对随机端点进行API调用（Get / Post / Put / delete）等。 url，payload等的详细信息来自数据库表。控制台应用程序获取httpClientFactory实例，如下所示。

 var serviceProvider = new ServiceCollection（）。AddHttpClient（）。BuildServiceProvider（）; 
 var httpClientFactory = serviceProvider.GetService< IHttpClientFactory>（）; 

对于我从表中获得的每条记录，我调用一个方法来进行API调用。对于该方法，我传递了httpClientFactory。在该方法中，我正在创建和使用HttpClient，如下所示。

 var httpClient = httpClientFactory.CreateClient（）; 
 // set headers 
 // make api call，ex ex response = await httpClient.PutAsync（apiTask.URL，content）; 
 //返回resposne 

我不在处理httpClient。当我看到内存使用量时，它会不断增加，即使在数小时后我也看不到它。

我按照以下文章  https://docs.microsoft.com/en-us/aspnet/芯/基本面/ HTTP的请求视图= aspnetcore-2.1 功能？;

我使用它吗？我应该使用"使用（httpClient）"

最好的问候，

In my c# console app (.net 4.6.1), I am required make API calls (Get/Post/Put/delete) etc to random endpoints. The details of the url, payload etc comes from a database table. The console app gets the httpClientFactory instance as shown below.

var serviceProvider = new ServiceCollection().AddHttpClient().BuildServiceProvider();
var httpClientFactory = serviceProvider.GetService<IHttpClientFactory>();

For each record I get from the table, I call a method to make an API call. To that method I pass the httpClientFactory. In that method, I am creating and using HttpClient as follows.

var httpClient = httpClientFactory.CreateClient();
//set headers
//make api call, for ex  var response = await httpClient.PutAsync(apiTask.URL, content);
//Return resposne

I am no where disposing of httpClient. As I see the memory usage, it keeps on increasing and I don't see it going down even after hours.

I followed the following article https://docs.microsoft.com/en-us/aspnet/core/fundamentals/http-requests?view=aspnetcore-2.1 

Am i using it right?. Should I be using the "using(httpClient)"
