websocket 用c++编写客户端的问题

用MFC CAsyncSocket这个类的socket与服务器connect之后,

我发送了头:Sec-WebSocket-Key,Sec-WebSocket-Version: 13 等内容
等取得了服务器返回的应答:Sec-WebSocket-Accept,Upgrade:Websocket等内容
应该是握手成功了。

之后我在用CAsyncSocket的send发送文本过去服务器就没有返回数据了,服务器也木有向我返回数据。是不是发送的数据要经过编码或者是什么?

请问有websocket 用c++编写客户端 示例代码吗?

应该维持一个心跳包来维持websocket的连接

lianghaoming7 呃,我用chrome抓包看到里面的frame.看到是定义发送一串字符串过去,然后服务器返回sys_auth=SUCCEED,可是我发送过去之后没有得到服务器的返回呢。

CSocket sockect;
sockect.Create();
CString ip =_T( "192.168.0.157");
bool ret = sockect.Connect(ip,8080);
if (ret)
{
Json::Value root;
root["lsh"] = "1234567890123";
root["clbh"] = "j001";
root["clbh"] = "j001";
root["kskm"] = "1";
root["sfzhm"] = "12345678";
root["kssj"] = "2015/11/25 9:52:12";
root["czlx"] = "0";

    string ss = root.toStyledString();
    string strlen;

    int len = ss.size();
    stringstream temp;
    temp.fill('0');
    temp.width(4);
    temp << len;
    temp >> strlen;

    // char *p = new char[len + 10];
    string data = "$$";
    data.append("12");
    data.append(strlen);
    data.append(ss);
    data.append("FF");
    sockect.Send(data.c_str(), data.size());
    sockect.Close();
}

大概看一下,我估计是服务器的问题。。。

WebSocket 服务端与客户端互发消息问题?

WebSocket 如果服务端不停的发消息给客户端,客户端处理消息又不停的给服务端发处理结果消息,这样会有什么问题?本人遇到的情况是如果服务端一直在发,就收不到客户端发的消息,是不是因为只有一个连接通道,服务端和客户端不能同时发?

WebSocket客户端与Java的Socket服务器通信

如何使用Go和gorilla websocket仅发送给一个客户端,而不是所有客户端

<div class="post-text" itemprop="text"> <p>I am trying to learn websockets with Go.

But what I don't understand is how you can send to only one client. Because in a real world application you will have users, and we don't want all users to receive the same message and same data. Is there a way for me to get the unique id of a connection which I can save in a database like redis and link it to a user id in the same database, and then use that websocket id to send back to a specific client if that user id received a message or a notification? Is this how one would go about and achieve something like this? If that is the case, how would I that?</p> </div>

将Websocket消息发送到Go中的特定客户端(使用Gorilla)

<div class="post-text" itemprop="text"> <p>I am very new to Go and have found myself working with sockets as my first project.

抖音上很火的时钟效果

反正,我的抖音没人看,别人都有几十万个赞什么的。 发到CSDN上来,大家交流下~ 主要用到原生态的 JS+CSS3。 具体不解释了,看注释: &lt;!DOCTYPE html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;meta charset="UTF-8"&gt; &lt;title&gt;Title&lt;/tit...

记录下入职中软一个月(外包华为)

我在年前从上一家公司离职,没想到过年期间疫情爆发,我也被困在家里,在家呆着的日子让人很焦躁,于是我疯狂的投简历,看面试题,希望可以进大公司去看看。 我也有幸面试了我觉得还挺大的公司的(虽然不是bat之类的大厂,但是作为一名二本计算机专业刚毕业的大学生bat那些大厂我连投简历的勇气都没有),最后选择了中软,我知道这是一家外包公司,待遇各方面甚至不如我的上一家公司,但是对我而言这可是外包华为,能...

为什么程序员做外包会被瞧不起?

二哥,有个事想询问下您的意见,您觉得应届生值得去外包吗?公司虽然挺大的,中xx,但待遇感觉挺低,马上要报到,挺纠结的。

手机经常收到"回复TD退订",回还是不回?今天总算是弄清楚了

自从有了微信和QQ,手机短信几乎很少再用了,但是我们手机里面还是经常会收到"回复TD退订"的消息,那到底要不要回复呢?今天就来告诉大家! 信息内容可能包括 推销信息 品牌活动日的时候,会根据你的用户浏览信息,或者购买记录,后续发送一些降价消息。 但是笔者想说我是缺那10块钱的人嘛,我缺的是1000块。 垃圾信息 虽然我们已经不经常用短信功能,但是还是有不少...

当HR压你价,说你只值7K,你该怎么回答?

当HR压你价,说你只值7K时,你可以流畅地回答,记住,是流畅,不能犹豫。 礼貌地说:“7K是吗?了解了。嗯~其实我对贵司的面试官印象很好。只不过,现在我的手头上已经有一份11K的offer。来面试,主要也是自己对贵司挺有兴趣的,所以过来看看……”(未完) 这段话主要是陪HR互诈的同时,从公司兴趣,公司职员印象上,都给予对方正面的肯定,既能提升HR的好感度,又能让谈判气氛融洽,为后面的发挥留足空间。...

面试官问我:如何加载100M的图片却不撑爆内存

还记得当年面试一个面试官问我怎么加载巨图才能不撑爆内存,我没回答上来,他说分片显示,我寻思特么分片能减少内存使用??现在可以打他脸了! 内容扩展 1.图片的三级缓存中,图片加载到内存中,如果内存快爆了,会发生什么?怎么处理? 2.内存中如果加载一张 500*500 的 png 高清图片.应该是占用多少的内存? 3.Bitmap 如何处理大图,如一张 30M 的大图,如何预防 OOM? A...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

培训班出来的人后来都怎么样了?(二)

接着上回说,培训班学习生涯结束了。后面每天就是无休止的背面试题,不是没有头脑的背,培训公司还是有方法的,现在回想当时背的面试题好像都用上了,也被问到了。回头找找面试题,当时都是打印下来天天看,天天背。 不理解呢也要背,面试造飞机,上班拧螺丝。班里的同学开始四处投简历面试了,很快就有面试成功的,刚开始一个,然后越来越多。不知道是什么原因,尝到胜利果实的童鞋,不满足于自己通过的公司,嫌薪水要少了,选择...

月薪22K程序员,打卡迟到10次,收到工资短信一脸懵逼

每家公司为了保证公司员工每天的工作时间,一般都会采用上下班打卡的工作制度,这其实是一个很常见的是,本身也没有什么问题的。正所谓无规矩不成方圆,公司肯定是有公司的规矩,虽然每个员工都很不喜欢这些规矩来束缚我们,但是公司也只是为了能更好的管理员工。但是一家公司如果一成不变的使用打卡制度,而不会去变通管理,也真不一定是好事。 打卡制度特别对于销售部门来说,不但会让公司发展不起来,还很容易丢失员工。但如...
