Question

运行MVC5应用程序尝试POST回我的控制器时出现此错误。

我在EnsureFiles（）方法期间发生了这种情况，但我根本没有尝试加载任何文件。

这是整个堆栈跟踪

我的表格非常简单

@using (Html.BeginForm())
{
<div class="form-group">
    In order to continue you must change your password.
</div>

<div class="form-group">
    @Html.LabelFor(x=> Model.OldPassword)
    @Html.TextBoxFor(x=> Model.OldPassword)
</div>

<div class="form-group">
    @Html.LabelFor(x => Model.NewPassword)
    @Html.TextBoxFor(x => Model.NewPassword)
</div>

<div class="form-group">
    @Html.LabelFor(x => Model.NewPasswordConfirm)
    @Html.TextBoxFor(x => Model.NewPasswordConfirm)
</div>

<div class="form-group">
    <input type="submit" class="btn btn-primary" value="Submit" /> 
    <input type="reset" class="btn btn-danger" value="Cancel" />
</div>


}

之前有没有人遇到过这个问题。我在网上得到了几个点击，但没有任何效果。

这回答了关闭Thinktecture IdSrv中的HttpLogging。

LoggingOptions = new LoggingOptions
{
  **EnableHttpLogging = false**,
  EnableWebApiDiagnostics = true,
  IncludeSensitiveDataInLogs = true,
  WebApiDiagnosticsIsVerbose = true,
},

Answer 2

将Azure Active Directory身份验证添加到以前没有身份验证的MVC Web应用程序时，我也遇到了此错误。

当我将 MVC和Web API配置代码之后的中的Startup.cs中的代码移动到之前的时，异常停止发生。

// Microsoft Azure Active Directory app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType); app.UseCookieAuthentication(new CookieAuthenticationOptions()); app.UseOpenIdConnectAuthentication( new OpenIdConnectAuthenticationOptions { ClientId = appSettings.IdaClientId, Authority = appSettings.IdaAuthority, PostLogoutRedirectUri = appSettings.IdaPostLogoutRedirectUri });

不支持HttpRequest.GetBufferlessInputStream
