Beast: response<string_body> has empty body

[mnisjk]

I'm attempting to parse a string http response (returned from libcurl) using a response_parser<string_body> object, but the parser.get().body() seems to always be empty.

I have a short code snippet the reproduces my issue.

Expected: parser.get().body() = "I'm a little teapot"
Observed: parser.get().body() = ""

string s =
    "HTTP/1.1 200 OK\r\n"
    "Content-Type: text/plain; charset=us-ascii\r\n"
    "Server: Fake Server\r\n"
    "Content-Length: 19\r\n"
    "\r\n"
    "I'm a little teapot\r\n"
    "\r\n";

boost::beast::error_code ec;
boost::beast::http::response_parser<string_body> p;

p.put(boost::asio::buffer(s), ec);

boost::beast::http::response<string_body> r = p.get();

// Prints: Ec=system:0
cout << "Ec=" << ec << endl;

// I'm able to get response headers
// Prints: Content-Type=text/plain; charset=us-ascii
cout << "Content-Type=" << r[field::content_type] << endl;

// But unable to get the response body
// Prints: body=
cout << "Body=" << r.body() << endl;

Any insight or tips would be greatly appreciated. I've spent more time than I'd care to admit wrestling with this.

Given the code above, these asserts should not trigger:

assert(p.is_header_done());
assert(! p.is_done()); // means you aren't done reading the message
assert(! p.eager()); // default is non-eager parsing

and adding this code before the call to put

p.eager(true);

should resolve your issue.

doh! Thanks @vinniefalco - works like a charm. This is user error, so closing issue.
