问如何使用fabric sdk初始化fabric CA

EN

 const caEndPoint = "https://localhost:7054"
 const caName = "ca-org1"
 let tlsOptions = {
    trustedRoots: [],
    verify: false
  };
const fabricCAServices = require('fabric-ca-client');
const caService = new fabricCAServices(caEndPoint, tlsOptions, caName);

const identityService = caService.newIdentityService();
    let registerObject = {
      enrollmentID: enrollmentId,
      type: type,
      affiliation: userOrg,
      maxEnrollments: maxEnrollments || 1,
      attrs: attributes,
      caname: caName
    }
const response = await identityService.create(registerObject, admin_user);
