Question

我试图使用Web浏览器项目的WebBrowser工具阻止Windows窗体应用程序C＃中的网站。所以目前我能够阻止预定义的网站，但是，我希望能够添加到不可能的阵列。所以我想知道是否有另一种方式？

private void webBrowser1_Navigating(object sender,WebBrowserNavigatingEventArgs e)        
{            
    String[] BlockList = new String[5]; //Array list stores the block list

    BlockList[0] = "http://www.google.com";
    BlockList[1] = "http://www.google.co.uk";
    BlockList[2] = "http://www.gmail.com";
    BlockList[3] = "http://www.yahoo.com";
    BlockList[4] = "http://www.bing.com";

    for (int i = 0; i < BlockList.Length; i++)
    {
        if (e.Url.Equals(BlockList[i]))
        {
            e.Cancel = true;
            MessageBox.Show("Booyaa Says No!", "NO NO NO", MessageBoxButtons.OK, MessageBoxIcon.Hand); // Block List Error Message
        }
    }
}

这是一个例子

public void method(){
 try {
 String apiKey = "AIzaSyB74usn5bPOiPi57DqC3mlaQHvIv5AEoWc"; 
        //API key provided by Google Console    
        Usuario usuario = usuarioDao.findByTelefono("600112207");
        String deviceID = usuario.getRegistrationId();
        System.out.println(deviceID);               
        Content content = new Content();
        //POJO class as above for standard message format
        content.addRegId(deviceID);       
        content.createData("Mensaje para el usuario:",usuario.getUsuario());
        URL url = new URL("https://android.googleapis.com/gcm/send");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/json");
        conn.setRequestProperty("Authorization", "key="+apiKey);
        conn.setDoOutput(true);
        conn.setDoInput(true);
        ObjectMapper mapper = new ObjectMapper();
        DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
        mapper.writeValue(wr, content);
        wr.flush();
        wr.close();
        inputStream = conn.getInputStream();
        int responseCode = conn.getResponseCode();

    } catch (IOException e) {
        e.printStackTrace();
    }



//the Content class
package antia.PFC.utils;
import java.io.Serializable;
import java.util.HashMap;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;

public class Content implements Serializable {

private static final long serialVersionUID = 4598819886093518574L;
public List<String> registration_ids;
public Map<String, String> data;
public void addRegId(String regId) {
    if (registration_ids == null)
        registration_ids = new LinkedList<String>();
    registration_ids.add(regId);
}
public void createData(String title, String message) {
    if (data == null)
        data = new HashMap<String, String>();
    data.put("title", title);
    data.put("message", message);

}
}

//the service-worker.js




//Version 0.1
'use strict';

console.log('Started', self);
self.addEventListener('install', function(event) {
self.skipWaiting();
console.log('Installed', event);
});

self.addEventListener('activate', function(event) {
console.log('Activated', event);
});

self.addEventListener('push', function(event) {
console.log('Push message', event);
if (event.data) { 
console.log('Push message',event.data.json())
}
var title = 'Mensaxe Quendas';
event.waitUntil(self.registration.showNotification(title,{
body : 'Ten vostede unha solicitude de cambio',
tag :'my-tag',
}));
});

然后你可以去

private List<string> BlockedUrls {get;set;}
private void webBrowser1_Navigating(object sender,WebBrowserNavigatingEventArgs e)        
{            
      if(BlockedUrls.Contains(e.Url.ToString())
      {
            e.Cancel = true;
            MessageBox.Show("Booyaa Says No!", "NO NO NO", MessageBoxButtons.OK, MessageBoxIcon.Hand); // Block List Error Message
        }
    }
}

通过数组阻止C＃WebBrowser上的网站
