基本的流程与 快速开始 章节中一致，将 handler 中代码改为以下内容：
/* eslint-disable no-console */
const { toTypeInfo } = require('@arcblock/did');
const { fromPublicKey } = require('@ocap/wallet');
const { fromBase58 } = require('@ocap/util');
const { getRandomBytes } = require('@ocap/mcrypto');
const getRandomMessage = (len = 16) => {
const hex = getRandomBytes(len);
return hex.replace(/^0x/, '').toUpperCase();
};
const action = 'request-text-signature';
module.exports = {
action,
onConnect() {
return {
signature: () => {
const data = getRandomMessage();
return {
description: 'Please sign the text',
type: 'mime:text/plain',
data,
};
},
};
},
// eslint-disable-next-line consistent-return
onAuth: ({ userDid, userPk, claims, updateSession }) => {
const type = toTypeInfo(userDid);
const user = fromPublicKey(userPk, type);
const claim = claims.find((x) => x.type === 'signature');
logger.info(`${action}.onAuth`, { userPk, userDid, claim });
if (claim.origin) {
if (user.verify(claim.origin, claim.sig, claim.method !== 'none') === false) {
throw new Error('Origin signature error');
}
}
updateSession({
result: {
origin: fromBase58(claim.origin).toString(),
sig: claim.sig,
},
});
},
};将前端部分调用 DID Connect 代码改为以下内容：
connectApi.open({
locale: 'zh',
action: 'request-text-signature',
onSuccess({ result }) {
// signatue data will be in result
},
messages: {
title: 'Request Text Signature',
scan: 'Please sign some text to continue',
},
});
