C#PostAsync-{StatusCode:401，ReasonPhrase:“未经授权"，使用ASP.NET MVC 4 [英] C# PostAsync - {StatusCode: 401, ReasonPhrase: 'Unauthorized' with ASP.NET MVC 4
问题描述
我正在使用ASP.NET MVC4，并使用PostAsync从一个MVC4项目到另一个MVC4项目中调用控制器中的方法.我在调用的控制器或方法中未使用任何身份验证属性.
I am using ASP.NET MVC4 and calling a method within a controller from one MVC4 project to another, using PostAsync. I am not using any authentication attribute within the called controller or method.
引用此链接:链接 修复了在本地运行应用程序并向服务器上的应用程序调用PostAsync时的问题.现在，当我将应用程序部署到服务器并尝试调用其他应用程序时，我得到了未授权的错误.我在做什么错了?
Referencing this link: link Fixed my issue when running application locally and calling PostAsync to application on server. Now, when I deploy the application to the server and try to call the other application I get the unauthorized error. What am I doing wrong?
在IIS中运行的两个应用程序都使用相同的站点和相同的应用程序池.
Both application running in IIS are using the same site, and the same application pool.
使用远程调试，这是服务器响应:
Using remote debugging, this is the server response:
{StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Cache-Control: private
Server: Microsoft-IIS/7.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
X-Powered-By: ASP.NET
Date: Fri, 23 Jun 2017 13:44:19 GMT
Content-Length: 6644
Content-Type: text/html; charset=utf-8
}}
这是我的代码:
using (var handler = new HttpClientHandler { UseDefaultCredentials = true })
using (HttpClient client = new HttpClient(handler) { BaseAddress = new Uri(Properties.Settings.Default.EnvironmentRootPath)})
{
List<string> orderNumbers = NumList;
var pairs = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("orderNumbers", string.Join(",", orderNumbers))
};
var content = new FormUrlEncodedContent(pairs);
// call sync
var response = client.PostAsync("CentralBroadcast/broadcastNewOrder", content).Result;
if (response.IsSuccessStatusCode)
{
//
}
else
{
//
}
}
推荐答案
问题似乎是由于从承载IIS 5.1或更高版本并使用完全限定域名的同一服务器访问本地Web应用程序引起的.
The problem seemed to be due to accessing a local web application from the same server that hosts IIS 5.1 or greater and uses a fully qualified domain name.
FQDN的域名需要在注册表中列为白名单，而我可以通过完成以下步骤来做到这一点:
The domain names of the FQDN need to be white listed in the registry, and I was able to do this by completing the steps below:
在进行任何调整之前创建注册表备份总是一个好主意

3)右键单击 MSV1_0 ，指向 New ，然后单击 Multi-String Value .
3) Right-click MSV1_0, point to New, and then click Multi-String Value.
4)键入BackConnectionHostNames，然后按Enter.
4) Type BackConnectionHostNames, and then press ENTER.
5)右键单击 BackConnectionHostNames ，然后单击修改".
5) Right-click BackConnectionHostNames, and then click Modify.
6)在值数据框中，键入主机名或本地计算机上站点的主机名，然后单击确定.
