部分代码:
http::response<http::string_body> res;
http::read(socket, buffer, res);
cout << "Result:" << res.result() << "." << res.result_int() << endl;
cout << "Contentlen:" << res.body().size() << endl;
cout << "has len:" << res.has_content_length() << endl;
cout << "body:" << res.body() << endl;
输出:
Result:Created.201
Contentlen:171
has len:1
一开始用dynamic_body,被坑的好惨,dynamic_body还不清楚原理,想通过res.body()获取包体死活不行,改为string_body直接搞定
研究了半天大概了解了下boost/beast/http/message.hpp里这样定义:
深入看下去,meaage继承自:
从上面的红色测试代码可看出,可以直接获取包头的一些信息,但是如果是dynamic_body的话不能用直接通过body()获取,还没研究出用法,知道其涉及到const_buffers_type、multi_buffer等相关类
赶项目,先不研究,有空了再研究
