Trying to understand the boost::beast multibuffer

问题 The Beast websocket example stores the data in a multibuffer: The implementation uses a sequence of one or more character arrays of varying sizes. Additional character array objects are appended to the sequence to accommodate changes in the size of the character sequence. When looking at the interface it is not completely clear to me how it works. If I read the descriptions it can be seen as an array of buffers. But it seems the output is only a single chunk of data. Does this mean the "one

Does this mean the "one or more arrays" are only applicable to the internal structure ? In the example code the data is read

一,interface 介绍 如果说 goroutine 和 channel 是 go 语言并发的两大基石,那 interface 就是 go 语言类型抽象的关键。在实际项目中,几乎所有的数据结构最底层都是接口类型。说起 C++ 语言,我们立即能想到是三个名词:封装、继承、多态。go 语言虽然没有严格意义上的对象,但通过 interface,可以说是实现了多态性。(由以组合结构体实现了封装、继承的特性) go 语言中支持将 method、struct、struct 中成员定义为 interface 类型,使用 struct 举一个简单的栗子 1 package main 2 3 type animal interface { 4 Move() 5 } 6 7 type bird struct{} 8 9 func (self *bird) Move() { 10 println("bird move") 11 } 12 13 type beast struct{} 14 15 func (self *beast) Move() { 16 println("beast move") 17 } 18 19 func animalMove(v animal) { 20 v.Move() 21 } 22 23 func main() { 24 var a *bird 25 var b

Thanks aloot 回答1: Yes it is possible: std::string s = "HTTP/1.1 200 OK\r\n" "Content-Length: 5\r\n" "\r\n" "*****"; error_code ec; request_parser<string_body> p; p.put(boost::asio::buffer(s), ec); 文章来源: C++ Boost 1.66 using Beast http request Parser for parsing an string

Solutions based on Boost.ASIO, which has become the de-facto C++ TCP library, are preferred. 回答1: The other day somebody recommended this on another thread : http://cpp-netlib.github.com/ I think this is as high-level as you will find, but I'm not sure if it's mature enough yet (I would say it probably is since they've proposed it for Boost inclusion). 回答2: Better late than never, here's a new answer to an old question.
