欧易 Injected providers API 是一个 JavaScript API,欧易将其注入用户访问的网站。您的 DApp 可以使用此 API 请求用户帐户,从用户连接的区块链读取数据,帮助用户签署消息和交易。
Dapp 可以通过如下方式访问注入的对象:
window.okxwallet.nostr
try {
const publicKey = await window.okxwallet.nostr.getPublicKey();
} catch (error) {
console.log(error);
}
window.okxwallet.nostr.getPublicKey(): Promise<string>
描述
返回当前连接的帐户的公钥。
返回值
publicKey
- string: 当前连接的帐户的公钥。try {
const publicKey = await window.okxwallet.nostr.getPublicKey();
} catch (error) {
console.log(error);
}
window.okxwallet.nostr.signEvent(event: Event): Promise<SignedEvent>
描述
对 Event 进行签名。
入参
event
- object
created_at
- number: 事件创建时间kind
- number: 事件类型tags
- string[][]: 事件标签content
- string: 事件内容返回值
event
- SignedEvent:除了包含 event 入参的所有属性外,还包含如下属性
id
- string: 唯一标识pubkey
- string: 公钥sig
- string: 签名const event = {
content: "hello",
kind: 4,
"tags": [

]
],
"created_at": 1700726837,
}
const signedEvent = await window.okxwallet.nostr.signEvent(event)
console.log(signedEvent.id)
console.log(signedEvent.pubkey)
console.log(signedEvent.sig)
window.okxwallet.nostr.nip04.encrypt(pubkey: string, message: string): Promise<string>
描述
根据 NIP-04 规范对消息进行加密
返回值
encryptMsg
- string: 加密的结果const pubkey = '693d3f45b81c1f3557383fb955f3a8cb2c194c44ffba1e2f4566e678773b44f8'
const msg = 'hello world'
const encryptMsg = await window.okxwallet.nostr.nip04.encrypt(pubkey, msg);
console.log(encryptMsg)
window.okxwallet.nostr.nip04.decrypt(pubkey: string, message: string): Promise<string>
描述
根据 NIP-04 规范对消息进行解密
返回值
decryptMsg
- string: 解密的结果const pubkey = '693d3f45b81c1f3557383fb955f3a8cb2c194c44ffba1e2f4566e678773b44f8'
const msg = 'VVPplRPF0w4dNZkuiQ==?iv=Nrb7gcph/9eKuqyuDx0yKQ=='
const decryptMsg = await window.okxwallet.nostr.nip04.decrypt(pubkey, msg);
console.log(decryptMsg)
window.okxwallet.nostr.on(event:string, callback: Function): Promise<void>
window.okxwallet.nostr.off(event:string, callback: Function): Promise<void>
描述
添加事件监听,目前支持的事件有:
accountChanged
:当用户切换账户时会触发该事件window.okxwallet.nostr.on('accountChanged', async () => {
const publicKey = await window.okxwallet.nostr.getPublicKey();
console.log(publicKey)
})
