C++ 连接到Poloniex推送API
我想连接到网络。他们在页面上写下以下内容: 要使用推送API,请连接到wss://api.poloniex.com 并订阅所需的提要 wss=WebSocket安全->受SSL保护 他们还举了Node.js和Autobahn | js的一个例子:C++ 连接到Poloniex推送API,c++,api,autobahn,wamp-protocol,autobahnws,C++,Api,Autobahn,Wamp Protocol,Autobahnws,我想连接到网络。他们在页面上写下以下内容: 要使用推送API,请连接到wss://api.poloniex.com 并订阅所需的提要 wss=WebSocket安全->受SSL保护 他们还举了Node.js和Autobahn | js的一个例子: var autobahn = require('autobahn'); var wsuri = "wss://api.poloniex.com"; var connection = new autobahn.Connection({ url: ws

connection.open();
但是,我不想使用JavaScript,而是使用C++。还有一个C++的自动库,叫做。我已经安装了它,并尝试运行它们,只需稍加修改(基本上只是硬编码地址和端口):
#包括在第80行
在我看来,问题在于API希望使用安全连接(wss:/)。这段代码似乎没有尝试创建SSL加密的连接,我不知道如何告诉会话我需要一个安全的连接
编辑:作者在文章中说,Autobahn无法处理混合http/wamp服务器,在使用WebSocket协议之前,首先需要对http请求进行升级。我知道Poloniex使用的是这样一种混合类型,但我已经尝试使用Autobahn |JS来访问API,在那里它工作正常,还发送了升级请求。那么这可能是高速公路的CPP问题
编辑2:如果上述情况属实,是否可以自己发送Http更新请求,甚至可能对连接进行SSL加密?我不确定,因为这可能会干扰库。我知道这是对您的问题的一个比较晚的回答,但问题似乎是您在连接到远程服务器时没有执行HTTP/Websocket升级。您正在使用的示例代码是使用rawsocket_端点传输设置的,我猜这意味着不存在HTTP Websocket升级或Websocket封装。我认为您的问题与SSL无关
要使Websocket连接正常工作,您应该查看使用的。不,不,不,这是一个延迟响应。不管是晚还是晚,我相信这可能是一个更直接的解决方案,为你(和任何其他挣扎在这个问题上的人)。我不敢透露,因为它可能会被竞争对手使用。但是,没有竞争的生活是什么!?无聊,就是这样。而且,我希望有人能在我之前发布这篇文章,所以给你!这是你想看到的变化,对吗
下面,您将看到一个利用websocketpp和autobahn | cpp连接到Poloniex推送api的实现。在这种情况下,它将接收对BTC_ETH书籍的更新
一般来说,这就是如何利用websocketpp和autobahn | cpp连接到实现WAMP协议(又称WAMP协议)的安全web套接字服务器的方法wss://ip-address.com:port)

std::cerr连接通常未建立..立即,只是第三次…是的,我注意到最近使用此解决方案(以及我用node js和Java编写的其他解决方案)。如果有人对此有解决方案(除了让poloniex获得更快的ssl握手(响应)之外),那么请让我知道。是否有可能增加一个设置…以某种方式等待握手的时间?是的,是的,这是余震。派对有点晚了,但我很想从更有经验的主管那里得到一些帮助-我似乎在加入这个领域时遇到了一个问题-我遇到了句柄读取帧错误(TLS短读取).有什么线索吗?
