How to add a request header to dynamic C# API client proxy / How to customize dynamic C# API client proxy?

• ABP Framework version: 5.0
• User Interface: MVC
• Database provider: EF Core

Hi all,
I have an ABP MVC server app and an ABP MVC client app. I'd like this MVC client application to be tenant-specific. That's why I am trying to add a request header to the client app's requests to recognize the tenant by the server app. I can do it with HttpClient but I'd like to get the benefit of "Dynamic C# API Client Proxy". Is there any way to add a request header to client proxies?

hi

If you are using the static proxy you can custom the base class(ClientProxyBase).

Hi @maliming
No, I am not using the static proxy, but I will have a look.

Hello @Codeio ,
You need to replace DefaultProxyHttpClientFactory

Moreover I've done in this way.

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(IProxyHttpClientFactory))]

public class CustomProxyHttpClientFactory : IProxyHttpClientFactory, ITransientDependency
{
    private readonly IHttpClientFactory _httpClientFactory;
    private IRemoteServiceConfigurationProvider _remoteServiceConfigurationProvider;
    private string _tenant;
    
    public CustomProxyHttpClientFactory(IHttpClientFactory httpClientFactory, IRemoteServiceConfigurationProvider remoteServiceConfigurationProvider)
    {
        _httpClientFactory = httpClientFactory;
        _remoteServiceConfigurationProvider = remoteServiceConfigurationProvider;
        _tenant = _remoteServiceConfigurationProvider.GetConfigurationOrDefaultAsync("Default").Result["Tenant"];

    }

    public HttpClient Create()
    {
        var client = _httpClientFactory.CreateClient();
        
        client.DefaultRequestHeaders.Add(TenantResolverConsts.DefaultTenantKey, _tenant);
        return client;
    }

    public HttpClient Create(string name)
    {
        var client = _httpClientFactory.CreateClient(name);
        client.DefaultRequestHeaders.Add(TenantResolverConsts.DefaultTenantKey, _tenant);
        return client;
    }
}
