缩写:
如果我按以下方式创建System.Web.HttpException:
var exception = new HttpException(403, "Forbidden");
我希望以下方法返回这些值，但它们不会:
var code = exception.GetHttpCode(); // is 0
var msg = exception.GetHtmlErrorMessage(); // is: null
编辑:实际上，
GetHttpCode()在第一次被调用时返回正确的数字，但是在第二次调用时返回0:var code = exception.GetHttpCode(); // is 403
code = exception.GetHttpCode(); // is 0
完整版:
我正在尝试对ASP.NET全局异常处理方法“Application_Error”进行单元测试。这是代码的一部分:
var httpException = server.GetLastError() as HttpException;
if (httpException != null)
{
response.StatusCode = httpException.GetHttpCode();
response.StatusDescription = httpException.GetHtmlErrorMessage();
// ...
单元测试使用模拟的
ServerUtilityBase对象(Moq)调用此方法，该对象会在调用HttpException时返回server.GetLastError():var exception = new HttpException(403, "Forbidden");
serverMock.Setup(server => server.GetLastError()).Returns(exception);
// ...
不幸的是，我不得不发现在错误处理代码中，
httpException.GetHttpCode()和httpException.GetHtmlErrorMessage()方法分别返回0或null。调用这些方法时，需要做些什么才能使
new HttpException(403, "Forbidden")返回403或"Forbidden"？不幸的是，不可能通过子类化来创建异常的Mock，因为所述方法是密封的。
最佳答案
httpException.GetHtmlErrorMessage()方法用于返回由ASP.NET运行时发送到浏览器的html，Patrick是正确的，因为您需要查看.Message属性以查看文本“forbidden”。如果要查看实际的html外观，则需要提供一个内部异常，该异常是ErrorFormatter可以使用的异常类型(例如SecurityException)。
var httpException = new HttpException(403, "Forbidden", new SecurityException());
Console.WriteLine(httpException.GetHttpCode());
Console.WriteLine(httpException.Message);
Console.WriteLine(httpException.GetHtmlErrorMessage());
将输出:
403
Forbidden
