我正在尝试处理MVC中的404错误,所有其他错误都是使用角度处理,因此不必担心其他异常。
我正在处理Global.asax页面中的404错误,如此
protected void Application_Error()
{
// if (Context.IsCustomErrorEnabled)
ShowCustomErrorPage(Server.GetLastError());
}
private void ShowCustomErrorPage(Exception exception)
{
var httpException = exception as HttpException ?? new HttpException(500, "Internal Server Error", exception);
Response.Clear();
var routeData = new RouteData();
routeData.Values.Add("controller", "ErrorHandling");
routeData.Values.Add("fromAppErrorEvent", true);
switch (httpException.GetHttpCode())
{
case 404:
routeData.Values.Add("action", "HttpError404");
break;
}
Server.ClearError();
IController controller = new ErrorHandlingController();
controller.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
}
但是当404错误发生时,执行方法
controller.Execute(new RequestContext(new HttpContextWrapper(Context), 的RouteData));
呈现页面的html而不是页面本身,如何进行更改以便我能够呈现页面本身而不是页面的html。

在您的网络配置上编写以下代码
import PyCapture2
import cv2
import matplotlib.pyplot as plt
import numpy as np
from PIL import Image
bus = PyCapture2.BusManager()
numCams = bus.getNumOfCameras()
camera = PyCapture2.Camera()
uid = bus.getCameraFromIndex(0)
camera.connect(uid)
camera.startCapture()
while True:
image = camera.retrieveBuffer()
row_bytes = float(len(image.getData())) / float(image.getRows());
cv_image = np.array(image.getData(), dtype="uint8").reshape((image.getRows(), image.getCols()) );
cv2.imshow('frame',cv_image)
cv2.waitKey(0)
