所以前一段時間我創建了一個web API來記錄誰在使用我們所有的應用程序。獲取未經授權:訪問被拒絕的網頁api
在開發中,它工作正常。它刺激,它工作了一個月,所有突然停止工作。就我所知,在prod網站上沒有任何變化。
如果我直接點擊webapi,它的工作原理。這是當我使用調用api的站點時,發生問題。
我檢查過,dev和prod之間的IIS設置是相同的。 (這兩個Windows身份驗證和它的高級設置都是相同的,匿名關閉。)
這兩個站點都使用相同的應用程序池(客戶端站點和api站點)。以域帳戶爲標識。
我已經完成了web.config和applicationhost.config的dev和prod之間的文件比較,沒有什麼看起來與衆不同。
我用盡了什麼檢查的想法。
的Web API控制器
[Authorize]
public class ValuesController : ApiController
{
public string Get(string samAccountName, bool success, string permissionName)
{
var returnValue = "Failed";
if (!string.IsNullOrWhiteSpace(samAccountName) && !string.IsNullOrWhiteSpace(permissionName))
{
// Do my logging (removed all the try catch etc to simplify thing)
returnValue = "Success";
}
return returnValue;
}
}
代碼打API客戶端上的
/// <summary>
/// This method calls a web api get method to log the call of the audit
/// </summary>
/// <param name="authorityName">This is the name of the permission to check</param>
/// <param name="success">This is the flag to determine if the call was successful.</param>
/// <returns>Returns an Async task</returns>
private async Task WriteToAuditLogAsync(string authorityName, bool success)
{
try
{
using (var client = new HttpClient(new HttpClientHandler { UseDefaultCredentials = true }))
{
client.BaseAddress = new Uri(GlobalConfiguration.AuditBaseAddress);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var values = string.Format(
CultureInfo.InvariantCulture, GlobalConfiguration.AuditApivalue,
this.userName.ToUpper(CultureInfo.InvariantCulture),
success.ToString(),
authorityName.ToUpper(CultureInfo.InvariantCulture));
// HTTP GET
var response = await client.GetAsync(values, HttpCompletionOption.ResponseHeadersRead).ConfigureAwait(false);
}
}
catch (Exception ex)
{
LogWriter.CriticalError(ex);
}
}

如果調用站點和API站點位於同一臺服務器上,則可能會遇到IIS環回阻止。請參閱http://serverfault.com/questions/485006/why-cant-i-log-in-to-a-windows-protected-iis-7-5-directory-on-the-server – howcheng
謝謝,如何。我會與ops團隊一起研究這一點。我還會研究ClientCertificateOption.Automatic和httpHandler – Lareau
由於某種原因,這個特定的錯誤消息在離開時被另一個替換(我將發佈一個關於該問題的新問題)。 我學到了什麼,當我碰到負載均衡的站點時,我會得到上面的錯誤。當我直接點擊該網站時,我得到了404 ..嘆氣 – Lareau
