一般依据标签对文章进行分类。tags在json_metadata中，这是字符串，要先JSON.parse转成对象形式

getCategory() {
  let category_net = "songofera"
  for (let i = 0; i < 100; i++) {
      let data_str = this.posts[i].json_metadata
      let data_obj = JSON.parse(data_str)
      if(data_obj.tags.includes(category_net)) {
        this.afterposts.push(this.posts[i])
        console.log(898, this.posts[i])
      }
  }
}

post.json_metadata还可以按需求写入其它的数据，有点类似MongoDB。这样的话易于对文章进行过滤，也可保存一些特殊的数据。

json_metadata: "{"tags":["cn","network-institute","markdown","html"],"app":"steemit\/0.1","format":"markdown"}"
eg:
let jsonMetadata = {"tags": tags, "dapp": "moochain", "format": "markdown", "cover": hash, "text": text}
JSON.stringify(jsonMetadata)

SteemJS中有些函数可以加上Async，以得到Promise的写法。比如：steem.api.getContentAsync

//获取某篇文章
steem.api.getContentAsync(author, permlink)

//获取一篇文章的回复
steem.api.getContentRepliesAsync(author, permlink)

//连续获取文章
steem.api.getDiscussionsByAuthorBeforeDateAsync(author, null, beforeDate, 5)
  .then(res=>{
    console.log(222, res)
  })

//获取作者的评论
let query = { limit : 10, start_author:'lemooljiang', "start_permlink": pPermLink}
comments = await this.steem.api.getDiscussionsByCommentsAsync(query)


//获取帐户历史
steem.api.getAccountHistoryAsync(account, from, limit)
  .then(res=>{
    console.log(122, res)}
  )

帐户数据几乎都在这里了，包括创建的时间，余额，点赞能量等等。

steem.api.getAccounts(['lemooljiang'], function(err, result) {
  console.log(789,err, result);
});

async getStates(){
  let username = "timool"
  let s = await this.steem.api.getAccountsAsync([username])
  console.log(789, s[0].balance)
