asynchronous http request in ruby
提问by Mohit Jain
require 'net/http'
urls = [
{'link' => 'http://www.google.com/'},
{'link' => 'http://www.facebook.com/'},
{'link' => 'http://www.yahoo.com/'}
]
urls.each do |u|
u['content'] = Net::HTTP.get( URI.parse(u['link']) )
end
print urls
This will work as procedural code.. I just want to hit a server, no issues about the order. How can i do that in ruby. One option is using threads.
这将作为程序代码工作..我只想打一个服务器，订单没有问题。我怎么能在 ruby 中做到这一点。一种选择是使用线程。
Here's an example using threads.
这是使用线程的示例。
require 'net/http'
urls = [
{'link' => 'http://www.google.com/'},
{'link' => 'http://www.facebook.com/'},
{'link' => 'http://www.yahoo.com/'}
]
urls.each do |u|
Thread.new do
u['content'] = Net::HTTP.get( URI.parse(u['link']) )
puts "Successfully requested #{u['link']}"
if urls.all? {|u| u.has_key?("content") }
puts "Fetched all urls!"
exit
end
end
end
Any better solution..??
有什么更好的解决方案吗？？
PS:- i want to hit mixpanel, so that's why I just want to make a http call and dont wait for the response.
PS：-我想点击mixpanel，所以这就是为什么我只想进行http调用而不等待响应。

Lightweight Async handling is the job of Threads (as you said) or Fibers.
轻量级异步处理是 Threads （如您所说）或Fibers 的工作。
Otherwise, you should consider EventMachinewhich is a very powerful tool.
否则，您应该考虑EventMachine，这是一个非常强大的工具。
EDIT: The above URL for Event Machine is dead. Here is their GitHub account, https://github.com/eventmachine/eventmachine. It serves as a good starting point.
编辑：上面的事件机 URL 已失效。这是他们的 GitHub 帐户，https://github.com/eventmachine/eventmachine。它是一个很好的起点。

Here is a great articlecovering the topic.
Generally, viable alternatives to using threads for this would be the use of a Fiberor you could use em-http-request. In the latter example you could leave out the callback handling for your particular purpose.
通常，为此使用线程的可行替代方案是使用Fiber或者您可以使用em-http-request。在后一个示例中，您可以出于特定目的省略回调处理。

If its just about plain http requests in async style, probably Unirestis the best fit to achieve it.
如果它只是异步风格的普通 http 请求，那么 Unirest可能最适合实现它。
Asnc request is as simple as:
Asnc 请求非常简单：
response = Unirest.post "http://httpbin.org/post",
headers:{ "Accept" => "application/json" },
parameters:{ :age => 23, :foo => "bar" } {|response|
response.code # Status code
response.headers # Response headers
response.body # Parsed body
response.raw_body # Unparsed body
}
