Requests and responses have Multipart boundary in boost beast. It is an HTTP POST request sent with the request body specially formatted as a series of parts, separated with MIME boundaries. Alternatively, the Boost::Beast是一个强大的网络库，它提供了一种简洁高效、易扩展的方式来编写基于协程的异步网络程序。本文介绍了如何使用Boost::Beast模块来实现一个基于协程的HTTP服务器，希望能对读者有所帮助。Boost::Beast是一个基于现代C++的高性能、易扩展的网络库，它提供了一种基于协程的方式来编写异步 boost/beast/http/parser. Beast. 1 Host: localhost:3003 User-Agent: Mozilla/5. With images this gives the expected output, it returns the raw data of the image, with any other filetypes (tested with txt files, zip files and 用beast 作为客户端发送http请求后读web服务端返回的数据，遇到了http::read 或http::async_read一直阻塞着，不返回，直到连接过期后被强制网络断开后read函数才返回。 看了官方文档，文档里这么描述的，read要一直等到end_of_stream时才回退出阻塞状态。也 ★indicates a new or updated section in this version. 4 概述; 该书采用 Creative Commons License 授权.
