Hyperledger fabric 如何让参与者/组织进入Converctor控制器？

我想在控制器内获得参与者模型，但我只有身份/指纹。。。。

---

问题是如何获得参与者模型？

答案是将身份/指纹与富couchdb查询结合使用

内部控制器使用此。发送者获取指纹ex

B5:38:A3:84:02:D1:EE:2B:CD:25:27:66:C0:F6:9E:4F:91:16:21:EE

接下来，首先创建worldstate查询，并在fauxton中进行测试

质疑

完成查询

现在创建一个utils.ts以在控制器中共享，如

packages/person cc/src/utils.ts

import { appConstants as c } from '@convector-rest-sample/common';
import * as bcrypt from 'bcrypt';
import { Participant } from 'participant-cc';

const bcryptSaltRounds: number = 10;

export const hashPassword = (password: string): string => {
  return bcrypt.hashSync(password, bcryptSaltRounds);
};

/**
 * get Participant by Identity/Fingerprint
 */
export const getParticipantByIdentity = async (fingerprint: string): Promise<Participant> => {
  const participant: Participant | Participant[] = await Participant.query(Participant, {
    selector: {
      type: c.CONVECTOR_MODEL_PATH_PARTICIPANT,
      identities: {
        $elemMatch: {
          fingerprint,
          status: true
        }
      }
    }
  });

  if (!!participant && !participant[0].id) {
    throw new Error('Cant find a participant with that fingerprint');
  }
  return participant[0];
}

检查couchdb

{
  "_id": "1-100-100",
  "_rev": "1-2b08d163d01dcfa5b9e9dc31bcc3b50c",
  "email": "pete.doe@example.com",
  "firstname": "Pete",
  "id": "1-100-103",
  "lastname": "Doe",
  "participant": {
    "id": "gov",
    "identities": [
      {
        "fingerprint": "B5:38:A3:84:02:D1:EE:2B:CD:25:27:66:C0:F6:9E:4F:91:16:21:EE",
        "status": true
      }
    ],
    "msp": "org1MSP",
    "name": "Big Government",
    "type": "io.worldsibu.examples.participant"
  },
  "password": "$2b$10$IYsgUSb/RA6zr4tT3u10HugCrxJH2loLsVUKjTkTiAAj3yewnR2SO",
  "roles": [
    "USER"
  ],
  "type": "io.worldsibu.examples.person",
  "username": "peter",
  "~version": "\u0000CgMBDgA="
}

完成

...
import { getParticipantByIdentity, hashPassword } from './utils';

@Controller('person')
export class PersonController extends ConvectorController<ChaincodeTx> {
  @Invokable()
  public async create(
    @Param(Person)
    person: Person
  ) {
    // get host participant from fingerprint
    const participant: Participant = await getParticipantByIdentity(this.sender);
    if (!!participant && !participant.id) {
      throw new Error('There is no participant with that identity');
    }
...
