샘플 URL을 생성하기 위해 제공된 공간에 URL과 서명을 넣으면 Google과 다른 서명이 나옵니다. 나는 멍청한 실수가 없다고 생각하고 다시 확인했다. 어쩌면 내가 잘못 이해했거나 파이썬 코드에서 뭔가 잘못 번역 한 것일까 요?Google API 문서 페이지에서 생성 된 서명과 일치 할 수 없습니다.
내 코드 :
def my_map_url
domain = "http://maps.googleapis.com/"
key = Figaro.env.maps_browser_api_key
path = "maps/api/staticmap?key=#{key}&size=450x300"
object.each do |location|
path += "&markers=#{location.latitude}%2C#{location.longitude}"
end
puts domain + path # What I put into Google's url input box
domain + path + "&signature=#{hmac_sha1(path)}"
end
def hmac_sha1(data)
digest = OpenSSL::Digest.new('sha1')
secret = Base64.urlsafe_decode64(ENV["MAPS_STATIC_SECRET"])
hmac = OpenSSL::HMAC.digest(digest, secret, data)
return Base64.urlsafe_encode64(hmac)
end
