这个cefsharp的专栏建立也有将近三年了。
本人的研究这块的群，也已经进入了不少的小伙伴了。
疫情期间在家有时间把，把这块的代码整理了下，发出来，给需要的小伙伴。
终极解决方案哦。而且是经过众多网友测试可行的。哈哈 ，等不及了，直接看代码
cef 版本57, 小伙伴注意你们的版本哦。
一、创建websocket 的server 和client 端
这里server代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Fleck;
namespace WSServer
{
class Program
{
static void Main(string[] args)
{
FleckLog.Level = LogLevel.Debug;
var allSockets = new List<IWebSocketConnection>();
var server = new WebSocketServer("ws://127.0.0.1:50000");
server.Start(socket =>
{
socket.OnOpen = () =>
{
Console.WriteLine("Open!");
allSockets.Add(socket);
};
socket.OnClose = () =>
{
Console.WriteLine("Close!");
allSockets.Remove(socket);
};
socket.OnMessage = message =>
{
Console.WriteLine(message);
allSockets.ToList().ForEach(s => s.Send("Echo: " + message));
};
});
var input = Console.ReadLine();
while (input != "exit")
{
foreach (var socket in allSockets.ToList())
{
socket.Send(input);
}
input = Console.ReadLine();
}
}
}
}
client端：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>websocket client</title>
<script type="text/javascript">
var start = function () {
var inc = document.getElementById('incomming');
var wsImpl = window.WebSocket || window.MozWebSocket;
var form = document.getElementById('sendForm');
var input = document.getElementById('sendText');
inc.innerHTML += "connecting to server ..<br/>";
// create a new websocket and connect
window.ws = new wsImpl('ws://127.0.0.1:50000/');
// when data is comming from the server, this metod is called
ws.onmessage = function (evt) {
inc.innerHTML += evt.data + '<br/>';
sendServerWesocketData(evt.data);
};
// when the connection is established, this method is called
ws.onopen = function () {
inc.innerHTML += '.. connection open<br/>';
};
// when the connection is closed, this method is called
ws.onclose = function () {
inc.innerHTML += '.. connection closed<br/>';
}
form.addEventListener('submit', function (e) {
e.preventDefault();
var val = input.value;
ws.send(val);
input.value = "";
});
}
function sendServerWesocketData(dataInfo){
bound.myMethod("jsData",dataInfo)
}
window.onload = start;
</script>
</head>
<body>
<form id="sendForm">
<input id="sendText" placeholder="Text to send" />
</form>
<pre id="incomming"></pre>
</body>
</html>
二、cefsharp 的操作js （非常重要的地方）
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;
namespace Browserform
{
//博主
public partial class JSGETWS : Form
{
public JSGETWS()
{
InitializeComponent();
}
static ChromiumWebBrowser web;
private void JSGETWS_Load(object sender, EventArgs e)
{
var re = new request();
//接收和发送的http消息
re.msg += Re_msg;
re.msg2 += Re_msg2;
web = new ChromiumWebBrowser("http://127.0.0.1:8888/myproject/");
web.Dock = DockStyle.Fill;
web.RequestHandler = re;
web.FrameLoadStart += Web_FrameLoadStart;
web.FrameLoadEnd += Web_FrameLoadEnd;
web.LoadingStateChanged += Web_LoadingStateChanged;
this.Invoke(new Action(() =>
{
this.Controls.Add(web);
}));
//browser表示你的CefSharp对象使用它的RegisterJsObject来绑定你的.net类
web.RegisterJsObject("bound", new BoundObject());
//在实际的JS代码中，你将使用这样的对象：
//bound.myProperty; // 使用此语法访问属性
//bound.myMethod(); // 使用此调用方法
}
private void Web_LoadingStateChanged(object sender, LoadingStateChangedEventArgs e)
{
}
private void Web_FrameLoadEnd(object sender, FrameLoadEndEventArgs e)
{
}
private void Web_FrameLoadStart(object sender, FrameLoadStartEventArgs e)
{
}
private void Re_msg2(string arg1, object arg2)
{
Console.WriteLine("arg1:" + arg1);
Console.WriteLine("arg2:" + arg2);
}
private void Re_msg(string obj)
{
Console.WriteLine("obj:" + obj);
}
public class BoundObject
{
public string MyProperty { get; set; }
public void MyMethod(string ShowNickName, string html)
{
try
{
Console.WriteLine("我来响应前台的的事件");
Console.WriteLine(ShowNickName);
Console.WriteLine(html);
}
catch (Exception ex)
{
}
}
}
}
下面这个 boundObject 里面就是前端传过来的websocket 的数据了。
怎么样是不是很简单，赶紧尝试下吧。
