ruby 中restclient怎麼設定逾時時間和捕獲逾時異常

標籤：

先吐槽一下百度，就是個坑，翻遍了百度都沒翻到答案，還好Google給力。

有兩個方法，第一：繞過restclient直接使用原生方法：

RestClient::Request.execute(:method => :post, :url => @url, :timeout => 90000000)

這樣做的好處是不用重寫restclient整個模組，可以直接使用，但我比較喜歡第二種方法，那就是重寫restclient這個模組，代碼如下：

require ‘net/http‘

require ‘openssl‘

require ‘stringio‘

require ‘uri‘

require ‘zlib‘

require ‘restclient‘

Timeout_vaule = 30

OpenTimeout_vaule = 30

module RestClient2

  # include RestClient

  def self.get(url, headers={}, &block)

    RestClient::Request.execute(:method => :get, :url => url, :headers => headers, :timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

  def self.post(url, payload, headers={}, &block)

    RestClient::Request.execute(:method => :post, :url => url, :payload => payload, :headers => headers,:timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

  def self.patch(url, payload, headers={}, &block)

    RestClient::Request.execute(:method => :patch, :url => url, :payload => payload, :headers => headers,:timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

  def self.put(url, payload, headers={}, &block)

    RestClient::Request.execute(:method => :put, :url => url, :payload => payload, :headers => headers,:timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

  def self.delete(url, headers={}, &block)

    RestClient::Request.execute(:method => :delete, :url => url, :headers => headers,:timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

  def self.head(url, headers={}, &block)

    RestClient::Request.execute(:method => :head, :url => url, :headers => headers,:timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

  def self.options(url, headers={}, &block)

    RestClient::Request.execute(:method => :options, :url => url, :headers => headers,:timeout =>Timeout_vaule,:open_timeout =>OpenTimeout_vaule, &block)

  end

end

這樣就可以直接如同使用原生的restclient一樣去使用它，不過這樣的話ruby內建的timeout這個東西就不太好使了，雖然原本就沒好使過，所以需要捕獲的異常就變成了：RestClient::RequestTimeout

當然，這個異常可能有其他捕獲辦法，但這個定位好像挺準的，所以就用這個了
