我正在尝试将2个空数组传递给一个方法,但是我得到了一个参数异常......我读了一遍但仍然无法弄清楚为什么会发生这种情况......
代码:
file = File.read("place_code.google.com")
paths = []
urls = []
def parseLog(file, paths)
file.each_line do |line|
match = line.match(/([a-z0-9]*GET\s)(.*puzzle\S*)/)
if match
paths << match[2]
end
end
return paths
end
错误:
:in `parseLog': wrong number of arguments (0 for 2) (ArgumentError)
答案 0 :(得分:1)
当您调用方法时,您没有传递所需的参数。要调用您的方法,您可以执行以下操作:
file = File.read("place_code.google.com")
paths = []
urls = []
class NewClass
def initalize
end
def parseLog(file, paths)
file.each_line do |line|
match = line.match(/([a-z0-9]*GET\s)(.*puzzle\S*)/)
if match
paths << match[2]
end
end
return paths
end
end
yourClass = NewClass.new()
yourClass.parseLog(file, path)
