how to add custome header to HttpApi.Client request !?

[RezaPouya]

how can i add custom header to outbound request of httpApi.Client for specific interface ?

[maliming]

Static proxy or dynamic proxy?

[RezaPouya]

dynamic proxy , I have an interface marker called InternalApiService , so , I want to add custom "X-Api-Key" which it value is stored in AppSetting per RemoteService , to be added to request ...

I tried by replacing ClientBaseProcxy<> and DynamicProxyHandler but it didnt work ( I don't know why )

We have multiple microservice , so I created a solution called []Famework and I put common configuration in every project of framework and then add the dll as module to microservices related module ...

for example , I Have this for HttpApi.Client

[DependsOn(typeof(AbpHttpClientModule))]
public class GajMarketFrameworkDomainHttpApiClientModule : AbpModule
{
    public override void PreConfigureServices(ServiceConfigurationContext context)
    {
    }

    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.AddTransient(typeof(GajMarketClientBase<>));
        context.Services.AddTransient(typeof(DynamicHttpProxyInterceptorClientProxy<>));

        ServiceDescriptor gajMarketInternalHttpProxyInterceptorServiceDescriptor =
            new(typeof(DynamicHttpProxyInterceptor<>), typeof(GajMarketInternalHttpProxyInterceptor<>), ServiceLifetime.Transient);

        context.Services.Replace(gajMarketInternalHttpProxyInterceptorServiceDescriptor);

        ServiceDescriptor gajMarketDynamicInternalHttpProxyInterceptorClientProxy =
            new(typeof(DynamicHttpProxyInterceptorClientProxy<>), typeof(GajMarketDynamicInternalHttpProxyInterceptorClientProxy<>), ServiceLifetime.Transient);

        context.Services.Replace(gajMarketDynamicInternalHttpProxyInterceptorClientProxy);
    }
}

but it doesn't work

one of main problem is that DynamicHttpProxyInterceptor, DynamicHttpProxyInterceptor , DynamicHttpProxyInterceptorClientProxy and many classes in source code in HttpApi.Clientmodule don't have interfaces , so when I wanted to use my own implementation , I was blocked because I couldn't inherit from them and then replace my own with it ( because actually I don't know how it really work so i can't confidentially replace it without fear of breaking code and I don't have time to dive deep in code ) , I did some workaround for this problem but it seems it doesn't work ...

from what I saw , replacing ClientBaseProxy<> with my own implementation is enough , but I can't do it !!!

In My opinion , the style of coding which is relaying on the class itself ( without having any proper interface to define functionality ) for auto dependency injection is not good in framework level .

currently I Use this

public class CustomProxyHttpClientFactory : IProxyHttpClientFactory, ITransientDependency { private readonly IHttpClientFactory _httpClientFactory; private readonly IConfiguration configuration; private IRemoteServiceConfigurationProvider _remoteServiceConfigurationProvider;

public CustomProxyHttpClientFactory(IHttpClientFactory httpClientFactory,
    IRemoteServiceConfigurationProvider remoteServiceConfigurationProvider,
    IConfiguration configuration)
{
    _httpClientFactory = httpClientFactory;
    _remoteServiceConfigurationProvider = remoteServiceConfigurationProvider;
    this.configuration = configuration;
}

public HttpClient Create()
{
    var client = _httpClientFactory.CreateClient();

    client.DefaultRequestHeaders.Add("X-Api-Key", configuration["App:ApiKey"]);

    return client;
}

public HttpClient Create(string name)
{
    var client = _httpClientFactory.CreateClient(name);

    client.DefaultRequestHeaders.Add("X-Api-Key", configuration["App:ApiKey"]);

    return client;
}

}

but I don't know how to get RemoteService Type and name in here so I could conditionally add apikey header and read apikey from something like this :

    if (x.GetType().IsAssignableTo(IInternalApiService))
    {
        client.DefaultRequestHeaders.Add("X-Api-Key", configuration[$"RemoteServiceApiKeys:{nameof(x)}"]);

    }

I think the DynamicHttpProxyInterceptorClientProxy<IInternalApiService> will works.

[ExposeServices(typeof(DynamicHttpProxyInterceptorClientProxy<IInternalApiService>))]
class MyDynamicHttpProxyInterceptorClientProxy : DynamicHttpProxyInterceptorClientProxy<IInternalApiService>

override AddHeaders()

It didn't work ...
