Tolitech.Results.Http 1.0.0-alpha03

Results.Http

Overview

The Results.Http library provides extension methods for handling HTTP responses and populating a Result object. It contains a method ReadProblemDetailsAsync that reads the content of an HttpResponseMessage asynchronously and populates the provided Result object with the details extracted from the response.

Usage

To use the ReadProblemDetailsAsync method, follow these steps:

1. Ensure you have a valid Result object to populate with response details.
2. Obtain an HttpResponseMessage containing the response from an HTTP request.
3. Call the ReadProblemDetailsAsync extension method on the Result object, passing the HttpResponseMessage as a parameter.

using Tolitech.Results.Http;

namespace Store.Ordering.Orders;

public sealed class OrderService : IOrderService
{
    private readonly HttpClient httpClient;

    public OrderService(OrderingHttpClient orderingHttpClient)
    {
        httpClient = orderingHttpClient.HttpClient;
    }

    public async Task<Result<CreateOrderResponse>> CreateOrder(CreateOrderRequest request, CancellationToken cancellationToken)
    {
        Result<CreateOrderResponse> result = new();

        string url = $"/orders";
        using var requestMessage = new HttpRequestMessage(HttpMethod.Post, url);
        requestMessage.Content = new StringContent(JsonSerializer.Serialize(request), Encoding.UTF8, "application/json");

        var response = await httpClient.SendAsync(requestMessage, cancellationToken);
        
        if (response.IsSuccessStatusCode)
        {
            var resp = await response.Content.ReadFromJsonAsync<CreateOrderResponse>();
            return result.OK(resp!);
        }

        await result.ReadProblemDetailsAsync(response);

        return result;
    }
