是否能通过 node.js SDK 来签名文章和创建合约？

thinkingincrowd

我尝试做的事情是，使用 SDK 来代替我在 P1 上面签名文章和创建合约。目的就是自动化，同时可以把分章发到其它平台，比如结合自己的 Hexo。

不过，经过测试，虽然我能参照 SDK 的 Sample 来签名文章，创建合约，创建 draft 文章，但是签名的文章和创建的合约却不会显示在我自己的页面。

以下是打出来的一些日志。

目前 DApp 之间的签名内容是相互独立的，press.one 主站实质上也是 PRS 网络的一个 DApp，所以你在 DApp 中创建的签名内容是不会出现在 press.one 中的。

根据你的需求，如果想自动化的将文章发布到 press.one 上，那么可以使用 press.one 主站账户的私钥或者授权 token 来签名文件。

thinkingincrowd

谢谢你的答复，并积极加我微信通知我。我的想法是：

P1 要做的就是协议，可以让所有授权的 Dapp 发布内容。不同 Dapp 签名的内容和性质不同。

P1 现在的页面，只是临时使用，不一定就是要作为文章发表的载体，以后可能又更好的编辑器，集成多平台的 Dapp 帮用户发不同的文章，图片，等数字内容。

P1 反而应该是一个大仓库，让用户看到不同 Dapp 都签名了什么，做整理。一旦有 Dapp 冒用用户签了内容都能发现和 revoke 或删除。

thinkingincrowd

@zhangpeng 为什么同样的方式，创建的 draft 文档就会在主站出现呢？请问怎么获取 press.one 主站账户的私钥，或者授权 token？我只有 keystore。有 sample code 吗？

区块链观光客

keystore解密之后就是私钥。

楼主还是有点区分不开PRS协议和press.one主站DApp，你说的大仓库本来就有，只是还没怎么做搜索功能 https://press.one/blockchain

thinkingincrowd

@区块链观光客我的疑问是，那为什么我另外申请的 Dapp 创建的 draft 文档，会出现在 Press.one beta 的 Dapp 上呢？我同样用自己的测试 Dapp 的 key 来认证啊。

keystore 如何解密为私钥？如何使用 P1 主站的私钥和 token 签名？这些在 Node.js SDK 并没有说明和样例。所以希望能获取些信息。

thinkingincrowd

经过尝试，通过以下的方法就可以通过 keystore 获得 Press.one 的私钥了：

const keyth = require('keythereum')

// address 改成你的 app address。就是下载的 keystore 文件上面那一长串字符
// keystore_path 就是放 keystore 文件的目录，目录下要有 keystore 这个名字的文件夹

const keyobj = keyth.importFromFile('address', 'keystore_path')

// 以下的 password 改成你登录/保护 P1 的密码
const privateKey = keyth.recover('password', keyobj)

console.log(privateKey.toString('hex'));

签名文件的方法和 SDK sample 差不多，只是初始化 client 的方式不同

const client2 = new PRS({ env: 'env', debug: true, address: appAddress, privateKey: appPrivateKey });

做了一个把 Hexo 的博客搬到 Press.one 的小工具。欢迎使用和打赏。 https://github.com/kenspirit/hexo-to-pressone

@thinkingincrowd 是也乎,(￣▽￣)

赞哪...有了模板,
用其它语言复制类似的也就很自然了

聆木

@thinkingincrowd 很赞啊，可以基于你的模板来做其它的类似的工作，谢谢！！！

被楼主同步的文章集中刷屏了，好可怕……感觉就像刷推翻到了rss bot一下同步几十条

区块链观光客

@thinkingincrowd 这个其实我也一直想吐槽，根本来说是官方Dapp的定位很迷造成的问题。V2的API还能操作Press.one的草稿和订阅，真的有点出乎意料
