一个脚本×关键词“百度说吧”你懂的

很久没更新但还是陆续有访问者，有点而不安。

发个和百度最近的说吧有点儿关系的脚本。

你懂得。

  # puts "usage: from_id to_id(not included)" and return  unless ARGV.count == 2  #why not works?
  if ARGV.count != 2
    puts "usage: from_id to_id(not included)" 
    return
  end
  
  from,to = ARGV
  from,to = from.to_i,to = to.to_i - 1  
  total = to - from + 1

  # status = 1 => success
  successed = 0
  start_time = Time.now

  (from..to).each do |uid|
    data = "&uid=#{uid}&t=t"  
    resp, data = http.post(path, data, headers)

    # puts 'Code = ' + resp.code + '   Msg = ' + resp.message  
    # resp.each {|key, val| puts key + ' = ' + val}
    puts "uid #{uid}: data:#{data}"
    json = JSON.parse(data)
    successed += 1 if json['status'].to_i == 1
    
  end

  end_time = Time.now
  puts "=== Task finished =============="
  puts "time: #{end_time-start_time}"

end

不过好久没写ruby有个问题请教下。

 

为什么

  # puts "usage: from_id to_id(not included)" and return  unless ARGV.count == 2  #why not works?

这句话的 return 不管用？

Hooopo 写道

puts 返回结果是nil
nil and return 这个是短路求值。。and前面是nil，后面根本没有执行

原来如此
豁然开朗！
