steem-python :是 Steem 官方的 Python 库,有一个BIP38加密钱包和一个实用的CLI实用程序 steempy。
steem-python 需要 Python 3.5 以上的版本,这里通过Anaconda 来安装,提供跨平台管理 python开发环境, 这可以让windows开发者和linux/MacOS开发者一样,尽心类似的开发操作.
MacOS10.14 安装 Anaconda3-2019.10 版本
官方安装地址:https://repo.anaconda.com/archive/Anaconda3-2019.10-MacOSX-x86_64.sh
如果官方下载慢,可用清华大学镜像:https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2019.10-MacOSX-x86_64.sh
$ cd ~$ wget https://repo.anaconda.com/archive/Anaconda3-2019.10-MacOSX-x86_64.sh$ bash Anaconda3-2019.10-MacOSX-x86_64.sh$ source ~/.bash_profile(base) ~$ python -V(base) ~$ pip -V
ubuntu18.04 安装 Anaconda3-2019.10 版本
官方安装地址:https://repo.anaconda.com/archive/Anaconda3-2019.10-Linux-x86_64.sh
如果官方下载慢,可用清华大学镜像:https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2019.10-Linux-x86_64.sh
$ cd ~$ sudo apt-get remove python3 python3-dev python3-pip$ sudo apt-get install libffi-dev libssl-dev make$ wget https://repo.anaconda.com/archive/Anaconda3-2019.10-Linux-x86_64.sh$ sh ./Anaconda3-2019.10-Linux-x86_64.sh$ source ~/.bashrc(base) ~$ python -V(base) ~$ pip -V
Anaconda3 安装 steem-python
Anaconda3 默认安装方式,会在用户登录后,自动进入 Anaconda3 的 python开发环境.
如果没有默认Anaconda3环境,可以手工方式进入Anaconda3环境:(base) ~$ conda activate
退出Anaconda3环境:(base) ~$ conda deactivate
$ cd ~$ conda activate(base) ~$ conda config --add channels conda-forge(base) ~$ conda install cryptography(base) ~$ git clone https://github.com/steemit/steem-python(base) ~$ cd steem-python(base) ~$ make install
备注:包安装(pip install steem
)容易出错.
使用命令行工具 steempy
帮助:steempy --help
设API节点:(base) ~$ steempy set nodes https://anyx.io,https://api.steemit.com
创建钱包密码:$ steempy changewalletpassphrase
添加steem账号:$ steempy addkey
查询本地钱包账号:$ steempy listaccounts
+-----------+---------+-----------------------------------+| Name | Type | Available Key |+-----------+---------+-----------------------------------+| ddxxxxnk | active | STMxxxxxx9yyE || ddnbbbbnk | posting | STM87YzixbssssEyyfU |+-----------+---------+-----------------------------------+
设本地钱包默认账号:$ steempy set default_account testdappcoder
设默认投票比重:$ steempy set default_vote_weight 88
查本地钱包设置:$ steempy config
----------------------------------------------+| Key | Value |+---------------------+-------------------------+| nodes | https://anyx.io,https://api.steemit.com || default_account | testdappcoder || default_vote_weight | 88 |+---------------------+-------------------+
示范一个扫描最新投票数据的机器人(print_live_votes.py):
from steem.blockchain import Blockchainfrom steem.post import Postblockchain = Blockchain()stream = map(Post, blockchain.stream(filter_by=['vote']))for vote in stream: print('vote:',vote)
执行程序:python print_live_votes.py
执行结果,和预期一致:
#cn #hive-180932 #chinese #hive-143316
