我正在尝试在我的Ruby应用程序中使用Redcloth,即使我只有两个参数,它也会给我wrong number of arguments (3 for 2)
错误。
这是我的代码:
def self.cleanup(string)
if string == "" || string == nil
""
else
string = self.iconvert(string, "ascii", "utf8")
RedCloth.include(RedCloth::Formatters::HTML)
redcloth = RedCloth.new(string)
redcloth.html_esc(string)
string = string.strip
string = string.gsub(/''/,"\"")
string = string.gsub(/\r/," ")
string = string.gsub(/\n/," ")
string = string.gsub(/\<br \/\>/," ")
string = string.gsub(/\<br\/\>/," ")
string = string.gsub(/ /," ")
redcloth.clean_html(string, {})
string
end
end
这是源代码:http://redcloth.rubyforge.org/classes/RedCloth/Formatters/HTML.html#M000052
def clean_html( text, allowed_tags = BASIC_TAGS )
text.gsub!( /<!\[CDATA\[/, '' )
text.gsub!( /<(\/*)([A-Za-z]\w*)([^>]*?)(\s?\/?)>/ ) do |m|
raw = $~
tag = raw[2].downcase
if allowed_tags.has_key? tag
pcs = [tag]
allowed_tags[tag].each do |prop|
['"', "'", ''].each do |q|
q2 = ( q != '' ? q : '\s' )
if raw[3] =~ /#{prop}\s*=\s*#{q}([^#{q2}]+)#{q}/i
attrv = $1
next if (prop == 'src' or prop == 'href') and not attrv =~ %r{^(http|https|ftp):}
pcs << "#{prop}=\"#{attrv.gsub('"', '\\"')}\""
break
end
end
这是我的日志:

答案 0 :(得分:0)
您收到错误是因为Redcloth源文件(base.rb)中method_missing
的定义只用两个参数定义(并且没有splat运算符)并且您正在使用两个参数调用未定义的方法当添加到方法名称时,会将三个参数传递给method_missing
。
违规通话似乎是对redcloth.clean_html
的通话。正如您在评论中指出的那样,clean_html
是一种私有方法,因此您无法通过正常的object.method
调用机制访问它。
