ruby - 法拉第的 "timeout"和 "open timeout"是什么？

Question

由于 Faraday 没有文档，我无法在任何地方找到它。法拉第什么是“timeout”，什么是“open timeout”？

Answer 1

如果您在 https://github.com/lostisland/faraday/blob/master/lib/faraday/request.rb 查看源代码然后你会看到:

#   :timeout      - open/read timeout Integer in seconds
#   :open_timeout - read timeout Integer in seconds

也许不是很有帮助？好吧，如果您在 https://github.com/lostisland/faraday/blob/master/lib/faraday/adapter/net_http.rb 查看 Faraday 的 Net::HTTP 适配器，你会看到:

http.read_timeout = http.open_timeout = req[:timeout] if req[:timeout]
http.open_timeout = req[:open_timeout]                if req[:open_timeout]

所以 Faraday 的 open_timeout 等同于 Net::HTTP 的 open_timeout，记录为:

Number of seconds to wait for the connection to open. Any number may be used, including Floats for fractional seconds. If the HTTP object cannot open a connection in this many seconds, it raises a TimeoutError exception.

Faraday 的 timeout 等同于 Net::HTTP 的 read_timeout，记录为:

Number of seconds to wait for one block to be read (via one read(2) call). Any number may be used, including Floats for fractional seconds. If the HTTP object cannot read data in this many seconds, it raises a TimeoutError exception.
