我尝试了以下ruby代码......
self.response.headers["Cache-Control"] ||= "no-cache"
self.response.headers["Transfer-Encoding"] = "chunked"
self.response.headers['Last-Modified'] = Time.now.ctime.to_s
self.response_body = Rack::Chunked::Body.new(Enumerator.new do |y|
10.times do
sleep 1
y << "Hello World\n"
end
end)
这在Unicron服务器中运行良好,但无法使用瘦服务器进行流式传输。我也尝试了1.5.0和2.0.0.pre,这不是很简单。
我尝试了以下机架代码,
class DeferredBody
def each(block)
@server_block = block
end
def send(data)
@server_block.call data
end
end
class RackStreamApp
def self.call(env)
Thread.new do
sleep 2 # simulate waiting for some event
body = DeferredBody.new
response = [200, {'Content-Type' => 'text/plain'}, body]
env['async.callback'].call response
body.send 'Hello, '
sleep 2
body.send 'World'
end
[-1, {}, []] # or throw :async
end
end
以上代码流&#34; Hello,World&#34;如果我们使用Unicorn Server,但代码不使用瘦服务器1.5.0流式传输(我也试过2.0.0-pre)
我可以使用瘦服务器来传输数据吗?
