所以看起来 boost::asio 内部的某些东西已经默默地吞噬了异常。 作为实验,我将异步操作切换为使用 boost::asio 库调用: boost::asio::awaitable<void> async_op() {autoexecutor = co_await this_coro::executor;autosocket = boost::asio::ip::tcp::socket{executor};std::cout<<"Starting resolve"<<std...

asio提供了read_until方便处理line-based protocol,写法如下: asio::streambuf sbuf; auto nSize = co_await asio::async_read_until(sock, sbuf, ‘\n’, use_awaitable); asio::streambuf::const_buffers_type bufs = sbuf.data(); std::string strInfo(asio::buffers_begin(bufs), asio::buffers_beg...
boost::asio::co_spawn(io_context, ws, boost::asio::detached); io_context.run(); 1. 2. 其中ws的签名为boost::asio::awaitable<void> ws() 建立tcp链接(以下步骤皆位于ws函数中) 这一步可以分为两个步骤,解析dns以及建立tcp链接。 auto executor = co_await boost::asio::this_coro::executor;...
boost::asio::spawn(my_strand, do_echo); 一般输入2个参数,参数1是 io_service 或者是 strand, 参数2是协程函数,类型如下: void coroutine(boost::asio::yield_context yield); 在协程函数中调用各个异步IO,异步操作将挂起协程,待异步操作完成后会自动继续协程。
我有一个库是用cppcoro编写的,希望与ASIO一起使用。但是每当我尝试从这个库中co_spawn一个协程。Boost抱怨可等待的类型不正确。asio::co_spawn(ctx, foo(),asio::detached); 我还尝试将协程封装在asio::awaitable中,但没有成功。::continuation_t<0> ...

1> E=boost::asio::io_context::strand 1> ] What happens (IMHO) is the following: spawn wraps the first parameter in a couple of functions and classes that ultimately call bind_executor.hpp:180 executor_binder_base(BOOST_ASIO_MOVE_ARG(e) e, BOOST_ASIO_MOVE_ARG(U)( u): executor_(BOO...
