c# - 如何解决错误 AADSTS7000218 : The request body must contain the following parameter: 'client_secret' or 'client_assertion'

Question

这就是我编写代码并尝试获取输出的方式。

The request body must contain the following parameter: client_secret or client_assertion

 static async Task<AuthenticationResult> getAccessToken()
 {
     string hardcodedUsername = "";
     string hardcodedPassword = "";
     string tenantName = "projectwidgets.com";
     string authString = "https://login.microsoftonline.com/" + tenantName;
     AuthenticationContext authenticationContext = new AuthenticationContext(authString, false);
     //Config for OAuth client credentials
     string clientId = "as";
     string key = "kk";
     string authority = String.Format(CultureInfo.InvariantCulture, aadInstance, tenantName);
     var authContext = new AuthenticationContext(authority);
     AuthenticationResult result = null;
     try
     {
         result = await authContext.AcquireTokenAsync("https://pwsnapitazure.azurewebsites.net", clientId, new UserPasswordCredential(hardcodedUsername, hardcodedPassword));
     }
     catch (Exception ex)
     {
          Console.WriteLine(ex.StackTrace);
          System.Diagnostics.Debug.WriteLine(ex.Message);
     }                        
     return result;
 }

由于 Azure 应用程序注册 UI 已从旧身份验证更改，您将需要启用一个名为“将应用程序视为公共(public)客户端”的附加设置。在默认客户端类型下，将此设置设置为是:

在 Manifest 中，您也可以通过设置来控制它:

"allowPublicClient": true

2022 年更新:

UI 名称更改为 Allow public client flows
