你不能。错误...您可以通过 monkey_patchingPatron::Session.request
方法,并在处理之前产生请求。但请注意,这不是“libcurl”请求,因为它只存在于 C 代码中,它是一个Patron::Request
实例。
另外,请注意您的猴子补丁可能随时中断,因为您必须重写整个方法!
yield
您在处理对 libcurl 的请求之前添加了一个,因此您有机会通过一个块来获取它。
req = nil
response = s.delete(uri) do |r|
req = r
end
# now req should be your request instance.
这是补丁的提示:
class Patron::Session
# You have to patch all the standard methods to accept a block
def get(url, headers = {}, &block)
request(:get, url, headers, &block)
end
# do the same for get_file, head, delete, put, put_file, post, post_file and post_multipart
def request(action, url, headers, options = {}, &block)
# If the Expect header isn't set uploads are really slow
headers['Expect'] ||= ''
