【问题描述】:
我正在尝试在我的解决方案中使用IHttpClientFactory 而不仅仅是HttpClient 的实例。
startup.cs:
services.AddHttpClient("Test", client =>
{
client.BaseAddress = new Uri("http://localhost:57863");
client.Timeout = new TimeSpan(0, 0, 30);
client.DefaultRequestHeaders.Clear();
});
在我的服务中需要一个 HttpClient:
private readonly Uri _clusterLinuxUri;
private readonly IHttpClientFactory _clientFactory;
public LiasseService(ConfigSettings settings, IHttpClientFactory clientFactory)
{
_clusterLinuxUri = new Uri($"{settings.LinuxClusterEndpoint}");
_clientFactory = clientFactory;
}
public async Task<LiasseDetails> CreateLiasseAsync(LiasseCreate liasseData)
{
using (var response = await _clientFactory.CreateClient("Test")
.PostAsJsonAsync($"{_clusterLinuxUri}{_createPath}", liasseData))
{
await response.CheckHttpError($"{nameof(CreateLiasseAsync)} - error in CL");
var detailsList = await response.Content.ReadAsAsync<LiasseDetailsList>();
return detailsList.Details.FirstOrDefault();
}
}
我还没弄清楚的部分是如何在Autofac中注入它。
程序.cs
private static void Main()
{
try
{
var builder = new ContainerBuilder();
builder.RegisterModule(new GlobalAutofacModule());
builder.RegisterServiceFabricSupport();
builder.RegisterStatelessService<FacadeCore>("xxx.FacadeCoreType");
using (builder.Build())
{
ServiceEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id, typeof(FacadeCore).Name);
Thread.Sleep(Timeout.Infinite);
}
}
catch (Exception e)
{
ServiceEventSource.Current.ServiceHostInitializationFailed(e.ToString());
throw;
}
}
public class GlobalAutofacModule : Module
{
protected override void Load(ContainerBuilder builder)
{
builder.RegisterType<ConfigSettings>();
builder.RegisterType<PaymentService>().As<IPaymentService>();
builder.RegisterType<MailerService>().As<IMailerService>();
builder.RegisterType<LiasseService>().As<ILiasseService>();
builder.RegisterType<AnalyseFinanciereService>().As<IAnalyseFinanciereService>();
builder.RegisterType<ApimService>().As<IApimService>();
builder.RegisterType<UserRepository>().As<IUserRepository>();
builder.RegisterType<ApplicationProcessRepository>().As<IApplicationProcessRepository>();
builder.RegisterType<LiasseRepository>().As<ILiasseRepository>();
builder.RegisterType<CustomUserIdProvider>().As<IUserIdProvider>();
}
}
我是否应该创建一些自定义客户端来实现IHttpClientFactory 以便能够注入它?我该怎么做?有什么例子吗?谢谢。
