Nodejs, vue.js 中使用，所以，请自行安装所需环境。

[lemooljiang]

cnpm install steem --save

//main.js
import steem from 'steem'

//设置steem节点,挂载到全局
steem.api.setOptions({ url: 'https://anyx.io' })
Vue.prototype.steem= steem

//公共节点，前面加上 https://

steem.broadcast.accountUpdate(wif, account, owner, active, posting, memoKey, jsonMetadata, function(err, result) {
  console.log(err, result)
})

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])
      }
  }
}

[lemooljiang]

steem.api.getTrendingTags('cn', 15, function(err, result) { 
  //获取在cn后的15个流行标签 ，留空表示从最热门的开始
  console.log(123, err, result)
})

[lemooljiang]

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)

[lemooljiang]

steem.api.getContent(author, permlink, function(err, result) {
  console.log(err, result)
})
eg:
steem.api.getContent('lemooljiang', 'steemjs-41', function(err, result) {
  console.log(934,err, result)
})

[lemooljiang]

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)}
  )

[lemooljiang]

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);
});

[lemooljiang]

let query = { limit : 5, start_author:'lemooljiang', start_permlink: ""}
  this.steem.api.getDiscussionsByComments(query, function(err, result) {
    console.log(265, err, result)
  })

[lemooljiang]

this.steem.api.getFollowers('lemooljiang', '', 'blog', 10, function(err, result) {
  console.log(111, err, result)
})

[lemooljiang]

this.steem.api.getFollowing('lemooljiang', '', 'blog', 10, function(err, result) {
  console.log(222, err, result)
})

steem.api.streamTransactions("head", function(err, result) {
    if (result && !err) {
      console.log(result)
    }
})
eg: 实时获取作者的文章或评论
getData() {
  this.steem.api.streamTransactions("head", function (err, result) {
    if (err) {
      alert("网络有问题！请更换API节点!")
    }
    let txType = result.operations[0][0] //获取操作类别
    let txData = result.operations[0][1] //获取操作内容
    if (txType == "comment" & txData.author == "lemooljiang") {  //获取作者的文章或评论
      let commentBody = txData.body
      let permlink = txData.permlink
      console.log(12345,commentBody)
    }
  })
}

可以获取用户的余额、代理和公钥等数据

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

[lemooljiang]

async getDelegateSp(){
  let user = 'lemooljiang'
  let res = await this.steem.api.getVestingDelegationsAsync(user, 'nutbox.mine', 1) 
  if(res.length === 0){
    return 0
  } else{
    return parseFloat(res[0].vesting_shares)
  }
  // let delegatedSp = parseFloat(res[0].vesting_shares) / spToVests 
  //刚查了下，如果滑有代理或是取消代理，就查询不到任何数值，为空，而不是0！
 },

[lemooljiang]

let author = "lemooljiang"
let permlink = "zn69yg"
let res = await this.steem.api.getActiveVotesAsync(author, permlink)
console.log(566, res)
