在WPF程序中打开网页：使用代理服务器并可进行JS交互
本项目环境：使用VS2010（C#）编写的WPF程序，通过CefSharp在程序的窗体中打开网页。需要能够实现网页后台JS代码中调用的方法，从网页接收数据，并能返回数据给网页。运行程序的电脑不允许上网，要求通过局域网内一个指定的代理服务器联网，并且只有该程序能通过代理服务器打开网页，直接用浏览器或其他应用程序仍然不允许上网（因此不能直接更改本机的LAN设置）。
首先介绍一下CefSharp，它是基于Google浏览器的一个组件，是可以用在WPF/WinForm客户端软件中的嵌入式浏览器。
如果你只需要通过客户端软件的一个窗体打开现成的网页，那么方法还是比较简单的，你可以直接参考http://www.w2bc.com/Article/54798这篇文章。
1、配置环境，加载CefSharp动态库
首先需要下载NuGet插件，它是免费、开源的包管理开发工具，专注于在 .NET 应用开发过程中，简单地合并第三方的组件库。使用该工具可以将CefSharp的完整程序包加载到工程中。下载地址：http://xz.cr173.com/soft2/nuget.tools.zip。
本项目是用VS2010编写的，因此运行NuGet.Tools for vs2010，安装后，在VS的“工具”菜单下会多出一项“NuGet程序包管理器”，见下图所示：
新建工程文件EmbeddedWebBrowser。点击“管理解决方案的NuGet程序包”，打开如下图所示的窗体：
在右上角联机搜索“CefSharp”，下载CefSharp.Wpf和CefSharp.Common。如果你用的不是WPF，而是WinForm，则需要下载CefSharp.WinForms和CefSharp.Common。下载的过程比较慢，网速不佳的情况下大概要一个小时左右。安装完成后，在工程文件所在目录下会多出“packages”目录。
2、MainWindow窗体：用于输入网页地址和初始化Cef
在工程文件中的MainWindow窗体中，添加一个用于输入网页地址的编辑框，和一个用于打开网页的按钮。MainWindow.xaml的代码如下所示：
<Window x:Class="EmbeddedWebBrowser.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="800" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded">
<Grid>
<DockPanel>
<StackPanel DockPanel.Dock="Top" Orientation="Horizontal">
<TextBlock Text="网页地址:" Margin="5"/>
<TextBox x:Name="txtAddress" Width="350" Margin="5"/>
<Button Content="Go" Margin="5" Click="OnGoClick" IsDefault="True"/>
</StackPanel> <Grid x:Name="MainGrid"> </Grid>
</DockPanel>
</Grid>
</Window>
该页面的后台代码MainWindow.xaml.cs如下所示：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using CefSharp; namespace EmbeddedWebBrowser
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
} /// <summary>
/// 窗体加载事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Window_Loaded(object sender, RoutedEventArgs e)
{
//默认打开的页面
txtAddress.Text = "http://www.baidu.com/";
//txtAddress.Text = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName.Replace("EmbeddedWebBrowser.vshost.exe", "index.html");
//设置代理服务器
var setting = new CefSharp.CefSettings();
setting.CefCommandLineArgs.Add("--proxy-server", "http://192.168.0.105:3128");
CefSharp.Cef.Initialize(setting, true, false);
} /// <summary>
/// “Go”按钮单击事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void OnGoClick(object sender, RoutedEventArgs e)
{
//获取要打开的页面地址
string url = txtAddress.Text; if (!string.IsNullOrWhiteSpace(url))
{
//打开网页
WebPageViewer viewer = new WebPageViewer(url);
MainGrid.Children.Insert(, viewer);
}
}
}
}
这里最关键的就是：setting.CefCommandLineArgs.Add("--proxy-server", "http://192.168.0.105:3128");这是用来设置代理服务器的IP和端口的。
CefSharp.Cef.Initialize(setting, true, false); 用来初始化CEF，即嵌入式浏览器。
2016-04-18补充：CefSharp.Cef.Initialize方法在程序里只能使用一次，如果把它写在一个会多次打开的子页面，就会报错：“只能初始化一次”。因此需要将这个方法写在主程序App.cs里。并且在程序退出前使用：CefSharp.Cef.Shutdown();否则程序关闭之后，可能会由于CefSharp.Cef未关闭，而使得该程序仍然存在后台进程中（可在任务管理器中查看），影响再次打开程序使用。
3、WebPageViewer.xaml：用于打开和显示网页
创建一个用户控件WebPageViewer.xaml，用于打开和显示网页，代码如下所示：
<UserControl x:Class="EmbeddedWebBrowser.WebPageViewer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:EmbeddedWebBrowser"
xmlns:uc="clr-namespace:EmbeddedWebBrowser"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid x:Name="MainGrid">
<uc:MaskLoading x:Name="maskLoading"/>
</Grid>
</UserControl>
这里的“MaskLoading ”是用来显示网页加载时的等待画面的，下面会进行介绍。
后台代码WebPageViewer.xaml.cs如下所示：
using CefSharp;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Net;
using CefSharp.Wpf; namespace EmbeddedWebBrowser
{
/// <summary>
/// 用于显示网页的控件
/// </summary>
public partial class WebPageViewer : UserControl, IRequestHandler
{
/// <summary>
/// 用于显示网页的自定义控件，构造函数
/// </summary>
/// <param name="url">网页地址</param>
public WebPageViewer(String url)
{
InitializeComponent(); var webView = new CefSharp.Wpf.ChromiumWebBrowser(); //注册一个JS对象
webView.RegisterJsObject("hy", new CallbackObjectForJs()); //注册网页加载事件：在顶级导航完成且内容加载到 WebView 控件中时发生
webView.Loaded += new RoutedEventHandler(webView_Loaded); MainGrid.Children.Insert(, webView);
webView.Address = url;
} /// <summary>
/// 网页加载完毕的事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
void webView_Loaded(object sender, RoutedEventArgs e)
{
maskLoading.Visibility = Visibility.Collapsed; //隐藏等待画面(正在加载...)
} public bool GetAuthCredentials(IWebBrowser browserControl, IBrowser browser, IFrame frame, bool isProxy, string host, int port, string realm, string scheme, IAuthCallback callback)
{
throw new NotImplementedException();
} public bool OnBeforeBrowse(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, bool isRedirect)
{
throw new NotImplementedException();
} public CefReturnValue OnBeforeResourceLoad(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IRequestCallback callback)
{
throw new NotImplementedException();
} public bool OnCertificateError(IWebBrowser browserControl, IBrowser browser, CefErrorCode errorCode, string requestUrl, ISslInfo sslInfo, IRequestCallback callback)
{
throw new NotImplementedException();
} public bool OnOpenUrlFromTab(IWebBrowser browserControl, IBrowser browser, IFrame frame, string targetUrl, WindowOpenDisposition targetDisposition, bool userGesture)
{
throw new NotImplementedException();
} public void OnPluginCrashed(IWebBrowser browserControl, IBrowser browser, string pluginPath)
{
throw new NotImplementedException();
} public bool OnProtocolExecution(IWebBrowser browserControl, IBrowser browser, string url)
{
throw new NotImplementedException();
} public bool OnQuotaRequest(IWebBrowser browserControl, IBrowser browser, string originUrl, long newSize, IRequestCallback callback)
{
throw new NotImplementedException();
} public void OnRenderProcessTerminated(IWebBrowser browserControl, IBrowser browser, CefTerminationStatus status)
{
throw new NotImplementedException();
} public void OnRenderViewReady(IWebBrowser browserControl, IBrowser browser)
{
throw new NotImplementedException();
} public void OnResourceLoadComplete(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IResponse response, UrlRequestStatus status, long receivedContentLength)
{
throw new NotImplementedException();
} public void OnResourceRedirect(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, ref string newUrl)
{
throw new NotImplementedException();
} public bool OnResourceResponse(IWebBrowser browserControl, IBrowser browser, IFrame frame, IRequest request, IResponse response)
{
throw new NotImplementedException();
}
} /// <summary>
/// 网页JS中调用的方法
/// </summary>
public class CallbackObjectForJs
{
public string action(string message)
{
//MessageBox.Show("测试");
return "收到网页消息：" + message;
}
}
}
该类实现IRequestHandler接口，是为了能够和JS网页进行交互，从GetAuthCredentials到OnResourceResponse的那几个空方法都是为了实现这个接口。当然这些在打开百度时是用不到的，接下来会用一个自己编写的JS网页做讲解。
4、与JS网页之间进行交互（如果只是打开百度等现成的网页，可以忽略这一项）
先编写一个网页index.html，如下所示：
<html>
<head>
<title>Test Page</title>
</head>
<body>
<p style="color: red">Hello, World!</p>
<button onclick = helloWebkit()>test</button>
<div><p> :) </p></div>
<script type="text/javascript">
function helloWebkit() {
alert("input:123");
var x = hy.action("123");
alert(x);
}
</script>
</body>
</html>
在该网页上有一个按钮test，点击后会弹出提示“input:123”，并调用hy类中的action方法，传入参数"123"。
将该网页放到DEBUG目录下，并将第2步MainWindow.xaml.cs中的网页地址改为该网页的本地地址：
txtAddress.Text = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName.Replace("EmbeddedWebBrowser.vshost.exe", "index.html");
其中EmbeddedWebBrowser为工程文件名称。
在第3步的WebPageViewer.xaml.cs中，注册了一个JS对象"hy"： webView.RegisterJsObject("hy", new CallbackObjectForJs());在 CallbackObjectForJs 类中实现了action方法（该方法名全为小写字母），接收网页上传来的参数，并将处理后的数据返回给网页。
5、在网页加载时显示等待画面
第三步的代码中有用到“MaskLoading ”，MaskLoading.xaml的代码如下所示：
<UserControl x:Class="EmbeddedWebBrowser.MaskLoading"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:EmbeddedWebBrowser"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid Opacity=".85">
<TextBlock Text="页面加载中..." VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Grid>
</UserControl>
该页面没有任何逻辑，只是为了在网页未加载完成时显示“页面加载中...”的提示信息。后台代码MaskLoading.xaml.cs如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes; namespace EmbeddedWebBrowser
{
/// <summary>
/// Interaction logic for MaskLoading.xaml
/// </summary>
public partial class MaskLoading : UserControl
{
/// <summary>
/// 显示等待画面“页面加载中...”
/// </summary>
public MaskLoading()
{
InitializeComponent();
}
}
}
6、其他注意事项
如果编译的时候报错，提示：“无法加载CefSharp.Core.dll组件”，则需要确保电脑上有VC++2013版本的运行库（2010版本是不行的）。运行库的下载地址：https://www.microsoft.com/en-us/download/details.aspx?id=40784。点击红色的DownLoad按钮，选择vcredist_x86.exe。
如果仍然报错，检查代码的生成属性：在工程文件上右击，选择属性——生成，打开如下图所示的界面：
目标平台需要选择“x86”。
2016-04-18补充：若平台下拉框中找不到“x86”，需要按下列步骤进行添加。
若选择了平台x86，运行时仍然报错，则需要将原有的x86平台删除（按下面的步骤打开配置管理器，在活动解决方案平台中选“编辑”，移除x86），再按下面的步骤重新添加。
