Configuring a services HttpClient per tenant

[chihabhajji]

Hello, i was wondering what is the best way to go about setting up a services HttpClient based on the current tenant info, i cant seem to use PerTenantOptions or named options because there are no httpclientoptions

Hi, the best method I've found it to use your own Options class with whatever settings you need in combination with a custom HttpClientHandler implementation which makes use of your Options class.

Info on HttpClientHandler:
https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclienthandler?view=net-6.0

I would register it as a transient and then register HttpClient with a factory method that instantiates the HttpClient with the HttpClientHandler. I hope this is helpful.

using options sounds like a better way than what i'm currently doing
public GateXRoadClient(FSHTenantInfo? tenantInfo, IConfiguration configuration) : base(Client) { if (tenantInfo?.XRoadSettings is not null && !string.IsNullOrEmpty(tenantInfo.XRoadSettings.SecurityServerToken) && !string.IsNullOrEmpty(tenantInfo.XRoadSettings.SecurityServerUrl)) { BaseUrl = tenantInfo.XRoadSettings.SecurityServerUrl; ApiKey = tenantInfo.XRoadSettings.SecurityServerToken; Client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("X-Road-ApiKey", $"token={tenantInfo.XRoadSettings.SecurityServerToken}"); } else { if (tenantInfo?.Id == MultitenancyConstants.Root.Id) { var ctx = configuration.GetSection(nameof(XRoadSettings)).Get<XRoadSettings>(); Client.DefaultRequestHeaders.Authorization = ctx.AuthenticationHeaderValue; BaseUrl = ctx.SSUrl; ApiKey = ctx.SSToken; } else { throw new UnauthorizedException("Unauthorized access to XROAD"); } } }
thank you for the suggestion
