Können wir httpclientHandler in iHttpclientFactory di -Implentation konfigurieren? ⇐ C#

[Anonymous]

Ich erhalte einen Multiple intermittierenden 'Socket -Ausnahmefehler' bei der Verwendung von httpclient (IHTTPClientFactory DI -Implementierung). IhttpclientFactory . Eine httpclientHandler wird pro Clientnamen erstellt. Die Fabrik verwaltet die Lebensdauer der httpclientHandler Instanzen. 'CreateClient () jedes Mal? Und das Pooling wird hier nicht geschehen.

Code: Select all

services.AddHttpClient("HttpClientFactory", client =>
{
client.Timeout = TimeSpan.FromSeconds(30);
})
.ConfigurePrimaryHttpMessageHandler(() =>
{
var handler = new HttpClientHandler();
handler.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
handler.SslProtocols = SslProtocols.Tls12 | SslProtocols.Tls11;
handler.UseProxy = false;
return handler;
});

< /code>
Verwendung < /p>

HttpMethod = httpMethodSelection(RequestType);
request = new HttpRequestMessage(HttpMethod, BaseUrl);
request.Headers.Add("Accept-Encoding", "gzip, deflate");
if (!string.IsNullOrWhiteSpace(AccessToken))
{
request.Headers.Add("Authorization", "Bearer " + AccessToken);
}
if (HttpMethod != HttpMethod.Get)
{
request.Content = new StringContent(JsonRequest, Encoding.UTF8, "application/json");
}

ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12 | System.Net.SecurityProtocolType.Tls11 | System.Net.SecurityProtocolType.Tls;
var _httpClient = _httpClientFactory.CreateClient("HttpClientFactory");
response = await _httpClient.SendAsync(request);

rawResponse = await response?.Content?.ReadAsStringAsync();
