user_agent_alias를 사용하여 "잘못된 인수 (예상 URI 객체 또는 URI 문자열)"를 던지는 기계화

Question

트위터에서 이미지를 가져 오려고하지만 user_agent_alias을 사용하면 충돌이 발생합니다. 사용자 에이전트를 지정해야합니다. 하지만 에이전트 별칭을 사용하는 이유는 무엇입니까? 그게 정상인가요?

함께하고 { |agent| agent.user_agent_alias = 'Mac Safari'} 블록하지 않고 자신을 시도해보십시오

require "mechanize" 
agent = Mechanize.new { |agent| agent.user_agent_alias = 'Mac Safari'} 
doc = agent.get("http://www.twitter.com") 
doc.images

감사합니다! 그것은`doc.images`을 검사 좋아하지 않는처럼 2.7.0

Answer 1

나는 코드가 기계화의 현재 버전을 사용하여 작업을 얻을 수 있었다. src 속성에 잘못된 URI가 있기 때문일 수 있습니다.
