[FEATURE]: Improvements to RestSharp dumping

[thePantz]

Description

Since we've updated to the latest RestSharp there may be new ways to approach dumping from.

I came across this comment and got inspired.
You could in theory, write a message handler that dumps the raw HttpRequestMessage rather than the RestSharp object. The nice part about this is HttpRequestMessage already has a ToString() overload. So there isn't much code needed to get a nicely formatted dump.

At first glance, it's pretty easy to get working.

1. Write a DelagatingHandler that takes in Boas ILogger

public class LoggingDelegatingHandler : DelegatingHandler
{
    public ILogger logger;

    public LoggingDelegatingHandler(ILogger logger, HttpMessageHandler innerHandler) : base(innerHandler)
    {
        this.logger = logger;
    }
    protected override HttpResponseMessage Send(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        logger.Log(request.ToString());
        return base.Send(request, cancellationToken);
    }

    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        logger.Log(request.ToString());
        return base.SendAsync(request, cancellationToken);
    }
}

2. Configure your RestClient to use the custom message handler

    private RestClient client;

    [SetUp]
    public void Initialize()
    {
        var options = new RestClientOptions
        {
            BaseUrl = new Uri( "https://dog.ceo/"),
            ConfigureMessageHandler = handler => new LoggingDelegatingHandler(new ConsoleLogger(), handler)
        };

        this.client = new RestClient(options);
    }

3. Make your request

    [Test]
    public void DumpTest()
    {
        var request = new RestRequest("api/breeds/image/random");
        this.client.Get(request);
    }

Since I configured this to use Boas ConsoleLogger the following shows up in the TestOutput window. But of course you could write a logger/Delegating Handler to log to file if you prefer 👍

2023-05-25 22:04:22Z [INFO] Method: GET, RequestUri: 'https://dog.ceo/api/breeds/image/random', Version: 1.1, Content: <null>, Headers:
{
  Accept: application/json, text/json, text/x-json, text/javascript, application/xml, text/xml
  User-Agent: RestSharp/110.2.0.0
}

All this to say, I believe we could replace most of the current RequestDumping feature with a custom message handler.

Alternatives

Work with what we got. Refactor the serialization objects to comply with the modern RestSharp objects.

Anything else?

I don't use the dumping feature myself that often so I could be missing something.
Could require a different implementation depending on what version of .NET you're on... Still prefer this over versions of RestSharp.

• I agree to follow Boa Constrictor's Code of Conduct.

I should mention, the same is true of HttpResponseMessage

protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
    logger.Log(request.ToString());
    var response = base.SendAsync(request, cancellationToken);
    logger.Log(response.Result.ToString());
    logger.Log(response.Result.Content.ReadAsStringAsync().Result);
    
    return response;
}

Output:

Obviously not the best implementation but as a quick PoC the info we need is accessible
