UnityHttpMessageHandler

Description

An HttpMessageHandler that can be used with HttpClient to perform web requests using UnityWebRequest.

UnityHttpMessageHandler enables sending web requests to HTTP servers using the standard HttpClient. This allows the use of libraries that expect to use HttpClient, but allow the developer to replace the underlying HttpMessageHandler that HttpClient uses. The request and response streams can be used to stream data for uploading and downloading, respectively.

UnityHttpMessageHandler can be used with GrpcChannel to make gRPC calls.

In a basic use case, UnityHttpMessageHandler can be used with HttpClient to make HTTP requests.

using UnityEngine;
using System.Net.Http;
using UnityEngine.Networking;
using Grpc.Core;
using Grpc.Net.Client;

public class GrpcChannelFactory
{
    public static GrpcChannel CreateGrpcChannel()
    {
        var httpHandler = new UnityEngine.Networking.UnityHttpMessageHandler()
        var channel = GrpcChannel.ForAddress("https://www.my-server.com", new GrpcChannelOptions
        {
            HttpHandler = httpHandler
        });
        return channel;
    }
}

using UnityEngine;
using System.Net.Http;
using UnityEngine.Networking;

public class MyBehaviour : MonoBehaviour
{
    void Start()
    {
        DoRequestAsync();
    }

    async void DoRequestAsync()
    {
        HttpClient client = new HttpClient(new UnityEngine.Networking.UnityHttpMessageHandler());
        var request = new HttpRequestMessage(HttpMethod.Get, "https://www.my-server.com");
        var response = await client.SendAsync(request);

        var status = response.StatusCode;
        var content = await response.Content.ReadAsStringAsync(); // content will contain the HTTP response body

        // Show results as text
        Debug.Log(content);
    }
}
