Voting Weight for SP less than 500 - SP小于500也可以通过程序来设置点赞百分比

justyy (81)in #cn • 7 years ago (edited)

It is said that, if you have less than 500 SP, you won't see this voting weight bar when you upvote.
江湖传言，SP小于500，你在点赞的时候是看不到这个条的：

It means that each vote is 100%, which you could verify on steemd.
如果看不到条，你的点赞是100%的，在 steemd 上查询是这样的：

I write a Python script to verify this:
但是我通过程序来验证了一下：

def vote(id, key, url, score = 100.0):
  wif = {
      "posting": key
  }
  try:
    steem = Steem(keys=wif)    
    return(steem.vote(url, score, id))
  except:
    pass

For example, vote('some_id_less_than_500sp', key, 'some_url', 30) is successful even for minnows with less than 500 SP
比如 vote('some_id_less_than_500sp', key, 'some_url', 30) 是成功的：

Apart from this, I learn that:
除此之外还意外了解到：

If a post or comment has been voted, when you upvote it again:

If the voting weight is the same as last time, nothing will happen i.e. nor the blockchain will not accept your vote, neither it will consume your voting power.
However, if the voting weight for that post or comment is different, the blockchain will accept this vote, update the voting weight and you will consume the voting power.

如果已经点赞了，下次再同样点赞的时候分两种情况:

如果点赞百分比和已经点赞的百分比是一样的，那么系统不会接受你的这次投票，不会消耗你的 Voting Power
如果点赞百分比和上次点赞的不一样，那么系统会授受你的这次投票，并且更新你的投票比重和消耗你的 Voting Power

You could also enforce a duplicate-upvote-check locally, marking a vote has been done in local file system or database.

我有点强迫，我怕重复投票，即使在比重一样的情况下也怕重复的投票，所以我本地先判断有没有已经投过，这个可以通过本地数据库记录，不过可以更简单的使用一下文件就可以：

def vote(id, key, url, score = 100.0):
  wif = {
      "posting": key
  }
  fn = id + '_' + md5(url) + '_' + str(score) 
  ok = not os.path.isfile(fn)
  if not ok:
    print("voted already: " + fn)  
    return  
  touch(fn)
  try:
    steem = Steem(keys=wif)    
    print("voted: " + fn)
    return(steem.vote(url, score, id))
  except:
    pass

This actually is 50% of the voting robots such as @randowhale and @minnowbooster where the 50% rest is to listen the transactions of the wallet, make votes and record them in the database (or filesystem).

这样其实已经完成了 @randowhale 或者 @minnowbooster 点赞机器人的50%工作, 剩下50%就是监听钱包到帐,然后根据钱的数量投个票, 记录在数据库(或者文件中).
