request_uri() lost Trailer?

Lines 937 to 950 in 2af9925

	local body, err = res:read_body()
	if not body then
	self:close()
	return nil, err
	end
	res.body = body
	if params.keepalive == false then
	local ok, err = self:close()
	if not ok then
	ngx_log(ngx_ERR, err)
	end

In function request_uri(), we read response body by res:read_body(), but Trailer is not be read before closing connection I think.

Correct me if I am wrong~

Yes, it looks like with the "single shot" interface (request_uri) we don't read the trailers. I don't remember if there was a reason for this or not, but perhaps it is simply an oversight.

With the generic interface you just need to call res:read_trailers() after reading the body.

PRs welcome :)
