我试图将一个接口注入我的HomeController,我收到此错误:
InvalidOperationException:尝试激活时无法解析类型"Microsoft.Extensions.Configuration.IConfiguration"的服务
我的Startup类如下:
public Startup(IApplicationEnvironment appEnv)
{
var builder = new ConfigurationBuilder()
.SetBasePath(appEnv.ApplicationBasePath)
.AddEnvironmentVariables()
.AddJsonFile("appsettings.json");
Configuration = builder.Build();
}
public IConfigurationRoot Configuration { get; set; }
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddEntityFramework()
.AddSqlServer()
.AddDbContext<ApplicationDbContext>(options => options
.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
services.AddMvc();
services.AddSingleton(provider => Configuration);
// Add application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();
}
public void Configure(
IApplicationBuilder app,
IHostingEnvironment env,
ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
app.UseApplicationInsightsRequestTelemetry();
if (env.IsDevelopment())
{
app.UseBrowserLink();
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else …我有一个 SPA 应用程序，它使用 AAD v2 身份验证与我的后端 Web API 进行通信。现在，我正在开发一个控制台应用程序来代表登录到 SPA 应用程序的用户调用 Microsoft Graph。
我有用户的有效访问令牌（用于调用后端 Web API）。我想使用此访问令牌来请求用于访问 MS Graph 的新令牌。
以下是使用 MSAL.NET 请求具有 MS Graph 范围的新访问令牌的控制台应用程序的代码：
string clientId = "<clientId>";
string clientSecret = "<clientSecret>";
string accessToken = "<validAccessTokenForWebApi>";
string assertionType = "urn:ietf:params:oauth:grant-type:jwt-bearer";
string[] scopes = new string[] { "User.Read", "Mail.Send" };
string graphAccessToken = null;
try
{
var app = ConfidentialClientApplicationBuilder
.Create(clientId).WithClientSecret(clientSecret).Build();
var userAssertion = new UserAssertion(accessToken, assertionType);
var result = app.AcquireTokenOnBehalfOf(scopes, userAssertion)
.ExecuteAsync().GetAwaiter().GetResult();
graphAccessToken = result.AccessToken;
}
catch (MsalServiceException ex) …我正在C#asp.net中创建定时在线测试.我使用本地机器时间创建了它.但是在数据库断开连接或系统挂起的情况下,倒数计时器必须从机器挂起或意外数据库断开连接的时间开始.例如,用户正在回答问题10分钟并且意外地系统被绞死.恢复后,倒计时必须从10分钟开始.有谁能帮我用C#编码？
我使用了以下代码,但它在上面的场景中没用.
int totalTime = (Convert.ToInt32(ViewState["totaltime"])) * 60;
DateTime startTime = (DateTime)ViewState["startTime"];
TimeSpan elaspedTime = DateTime.Now.Subtract(startTime);
Literal1.Text = elaspedTime.Hours.ToString() + "h" + ":" + elaspedTime.Minutes.ToString() +
"m" + ":" + elaspedTime.Seconds.ToString() + "s";
int finish = Convert.ToInt32(elaspedTime.TotalSeconds);
int remaingsec = (totalTime - finish);
TimeSpan remainingtime = TimeSpan.FromSeconds(remaingsec);
string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s",
remainingtime.Hours,
remainingtime.Minutes,
remainingtime.Seconds,
remainingtime.Milliseconds);
LIteral2.Text = answer;
if (totalTime == finish)
{
lnkFinish_Click(sender, e);
Response.Redirect(@"~/Error.aspx");
}
有人可以解释为什么section计数器值在所有h2标签中都打印0 ？
这是源代码:
<!DOCTYPE html>
<html>
<head>
<style>
body {
counter-reset: section;
counter-reset: subsection;
}
h1::before {
counter-increment: section;
content: "Section " counter(section) ". ";
}
h2::before {
counter-increment: subsection;
content: counter(section) "." counter(subsection) " ";
}
</style>
</head>
<body>
<h1>HTML tutorials:</h1>
<h2>HTML Tutorial</h2>
<h2>CSS Tutorial</h2>

<p><b>Note:</b> IE8 supports these properties only if a !DOCTYPE is specified.</p>
</body>
</html>我可以通过这样的请求访问我的一个驱动器上的文档：
https://graph.microsoft.com/v1.0/me/drive/root/children
我可以通过这样的请求访问我公司的根共享点站点的文档库：
https://graph.microsoft.com/v1.0/drive/root/children
它给了我“根”库的内容：
https://<my company>.sharepoint.com/Shared%20Documents
我无法访问我创建的 SP 子站点的文档库。例如这个：
https://<my company>.sharepoint.com/samplesp/Shared%20Documents
如何使用 MS Graph 访问这样的文档库？
