是通过以下步骤:
Install-Package Microsoft.Identity.Client
using Microsoft.Identity.Client;
string clientId = "YourClientId";
string clientSecret = "YourClientSecret";
string authority = "https://login.microsoftonline.com/YourTenantId";
ConfidentialClientApplication app = new ConfidentialClientApplication(clientId, authority, clientSecret);
在上述代码中,需要替换"YourClientId"、"YourClientSecret"和"YourTenantId"为实际的应用程序标识符、客户端密钥和租户ID。
app.HttpClientFactory = new HttpClientFactory
{
HttpClientHandler = new HttpClientHandler
{
AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate,
UseProxy = false,
UseDefaultCredentials = true,
PreAuthenticate = true,
AllowAutoRedirect = true,
UseCookies = true,
MaxAutomaticRedirections = 50,
MaxConnectionsPerServer = 100,
MaxResponseHeadersLength = 100,
MaxRequestContentBufferSize = 1000000
}
};
上述代码中的HttpClientHandler属性配置了一些常见的HTTP客户端处理程序选项,以便在请求失败时进行重试。
string[] scopes = { "https://graph.microsoft.com/.default" };
AuthenticationResult result = await app.AcquireTokenForClient(scopes).ExecuteAsync();
上述代码中的"scopes"参数指定了要请求的访问令牌的范围。
总结: 创建允许重试Windows服务的ConfidentialClientApplication的正确方法包括导入MSAL库、创建ConfidentialClientApplication对象、配置重试策略,并使用该对象进行身份验证和授权操作。这样可以确保Windows服务在身份验证失败时能够进行重试,并成功获取访问令牌。
