ServiceStack JsonServiceClient OnAuthenticationRequired [英] ServiceStack JsonServiceClient OnAuthenticationRequired

问题描述

这是 StackOverflow 上的第一篇文章，所以如果我做错了什么，请耐心等待.

This is the very first post on StackOverflow, so please be patient if am doing anything wrong.

我正在使用 ServiceStack 来创建 RESTful 网络服务.在开发示例 Windows 客户端时，我发现了 JsonServiceClient.OnAuthenticationRequired 属性，但无法使其正常工作.我没有找到关于它的文档 - 我假设这是一种在服务器需要身份验证时提供用户凭据的委托方法 - 但我无法让它工作.

I am using ServiceStack to create RESTful webservices. While developing a sample windows client I have found the JsonServiceClient.OnAuthenticationRequired property, but was unable to get it working. I have found no documentation about it - and I am assuming that this is a delegate method to supply user credentials when the authentication is required by the server - but I have not been able to get it working.

这里有一些我正在尝试使用的示例代码(它是 VB.Net，但它对于 C# 爱好者来说也应该是非常易读的).

here some sample code I am trying to use (it is VB.Net, but it should be very readable also for C# lovers).

Private _clientAuthenticationRequested As New Action(Of WebRequest)(AddressOf InteractiveAuthentication)

Private Sub Login
....
    _client = New JsonServiceClient(WEBSERVER_ADDRESS)
    _client.OnAuthenticationRequired = _clientAuthenticationRequested
....
End Sub
Private Sub InteractiveAuthentication(SourceRequest As WebRequest)
    SourceRequest.Credentials= ... set some valid credentials
End Sub

InteractiveAuthentication"永远不会被触发，即使客户端启动需要身份验证的请求.

The 'InteractiveAuthentication' is never triggered, even when the client starts a request requiring authentication.

有人知道属性的含义和用法吗?

Anybody has an idea about the property meanings and usage?

非常感谢阿尔贝托

推荐答案

好奇，我查了源.当我读到它时，如果 WebRequestUtils.ShouldAuthenticate(ex, this.UserName, this.Password) 返回 true，则会在异常处理过程中调用 OnAuthenticationRequired 函数.该函数内容如下:

Curious, I checked the source. As I read it, the OnAuthenticationRequired function is called in the exception handling process, if WebRequestUtils.ShouldAuthenticate(ex, this.UserName, this.Password) returns true. That function reads as follows:

internal static bool ShouldAuthenticate(Exception ex, string userName, string password)
{
    var webEx = ex as WebException;
    return (webEx != null
            && webEx.Response != null
            && ((HttpWebResponse) webEx.Response).StatusCode == HttpStatusCode.Unauthorized
            && !String.IsNullOrEmpty(userName)
            && !String.IsNullOrEmpty(password));
}

当需要身份验证时，您的主机是否返回 Unauthorized 状态代码?用户名和密码.他们是否有人居住?

Is your host returning a status code of Unauthorized when authentication is required? What about username & password. Are they populated?

相关代码在这里:protected virtual bool HandleResponseException 方法内的src/ServiceStack.Common/ServiceClient.Web/ServiceClientBase.cs.

The relevant code is here: src/ServiceStack.Common/ServiceClient.Web/ServiceClientBase.cs inside the protected virtual bool HandleResponseException method.
