Hi Antoine, I'd like to point you to the new discussion group: https://groups.google.com/group/cpp-netlib where you should be posting further questions. I've CC'ed the new group to this response -- you'll have to subscribe to that list too so that we can continue the conversation over there instead. > I'm trying to use cpp-netlib 0.9 to implement a simple client. > But I'm having trouble getting a response header , I've read the example > http_client.cpp. > In that example you use an iterator to print all the headers.. however I saw > in : > headers.cpp : > struct response_headers_wrapper { ... > range_type operator[] (string_type const & key) const { > return message_.headers().equal_range(key); > } > I would like to use the headers wrapper to call directly like : > using namespace boost::network; > typedef http::basic_client<http::tags::http_default_8bit_tcp_resolve, 1, > 1> http_client; > http_client client; > std::string req_str = "http://localhost/";; > http_client::request request(req_str); > request << header("Connection", "close"); > http_client::response response = client.get(request); > This section here is my problem : > headers_range<http_client::response>::type headers OR > basic_response<Tag>::headers_container_type = response.headers(); ??? > const string<tags::default_string>::type cookie_header("Set-Cookie"); > TYPE ?? = headers[cookie_header] > But really I'm having a hard time figuring out the correct types... with the > tags etc..

You'd want to read up on Boost.Range from http://www.boost.org/libs/range -- the way it would be used is this way: typedef typename headers_range<http_client::response>::type headers_range_type; range_type cookie_range = headers(response)["Set-Cookie"]; No special tags you need to worry about. ;) Once you have the range, you can then deal with it like any Boost.Range: BOOST_FOREACH(http_client::response::header_type const & header, cookie_range) { // header.name and header.value now usable in this context } Or something to that effect -- I'm doing this from memory so I may have gotten a few things wrong. :D > A simple example that would illustrate how to get a std::string for a > specific header would help me to understand quite a lot > That above should help.
