问题 I have a dotnet framework application which performs POST api requests to a remote server running Apache. It intermittently fails with the error: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. This occurs on the second request to the server when done over a keepalive TLS connection, and so occurs more frequently in production systems under heavy load and less frequently or not at all in development environments. We have tried:

问题 I have the following issue. I have a proxy set. If a request via proxy very slow or has crashed I would like to try again without proxy. For setting proxy I have the following code in the Startup.cs file: services.AddHttpClient<ICheckPackagesService, CheckPackagesService>(x => { x.Timeout = TimeSpan.FromSeconds(10); }).ConfigurePrimaryHttpMessageHandler(() => new SocketsHttpHandler { Proxy = new WebProxy(IpService.GetIp()) }); But I can't imagine what I have to do for sending new one request

问题 I need to interact with a third party endpoint that only accepts form encoded payloads. The endpoint wants complex data types at this endpoint, meaning something like this (but form encoded, not JSON): { "foo": "bar", "baz": { "zip": "zap" } } My googling and the docs for the endpoint indicates that this should be form encoded like this: foo=bar&baz[zip]=zap I am using HttpClient and I want to use FormUrlEncodedContent but when I do it is replacing my [] with escaped characters. public class

问题 I am looking for c# HTTP client that doesn't throw when it gets an HTTP error (404 for example). This is not just a style issue; its perfectly valid for a non 2xx reply to have a body but I cant get at it if the HTTP stack throws when doing a GetResponse() 回答1: All the System.Net.Http.HTTPClient methods that return Task<HttpResponseMessage> do NOT throw on any HttpStatusCode. They only throw on timeouts, cancellations or inability to connect to a gateway. 回答2: If you are using the HttpClient
