Question

我从master分支中删除了fabric-repository。使用node-SDK

我正在尝试注册用户并为其注册属性hf.registrar.Role属性并请求具有相同属性的证书
然后我正在调用一个事务并尝试在chaincode中解码他的属性

我也在尝试在节点层解码他的属性但我得到属性为null，属性状态为false

  var  attr1_req={name:"hf.Registrar.Roles",required:true};
 attr_req.push(attr1_req);
 var attr_req=[];

 var reg_attr=[];
 var attr_reg={name:"hf.Registrar.Roles",value:"this is roles"};
 reg_attr.push(attr_reg);


return hfc.newDefaultKeyValueStore({
    path: getKeyStoreForOrg(getOrgName(userOrg))
}).then((store) => {
    client.setStateStore(store);
    // clearing the user context before switching
    client._userContext = null;
    return client.getUserContext(username, true).then((user) => {
        logger.debug("User :"+user)
        if (user && user.isEnrolled()) {
            logger.info('Successfully loaded member from persistence');
            return user;
        } else {
            let caClient = caClients[userOrg];
            logger.debug("Ca client: "+caClient)
            return getAdminUser(userOrg).then(function(adminUserObj) {
                member = adminUserObj;

                return caClient.register({
                    enrollmentID: username,
                     affiliation: userOrg + '.department1',
                     attrs:reg_attr
                }, member);
            }).then((secret) => {
                enrollmentSecret = secret;
                logger.debug(username + ' registered successfully');
                return caClient.enroll({
                    enrollmentID: username,
                    enrollmentSecret: secret,
                    attr_reqs:attr_req

                });
            }, (err) => {
                logger.debug(username + ' failed to register');
                return '' + err;
                //return 'Failed to register '+username+'. Error: ' + err.stack ? err.stack : err;
            }).then((message) => {
                if (message && typeof message === 'string' && message.includes(
                        'Error:')) {
                    logger.error(username + ' enrollment failed');
                    return message;
                }
                logger.debug(username + ' enrolled successfully');

                logger.debug("message :"+message.certificate);
                let cert = X509.parseCert(message.certificate);
                logger.debug("parsed cert: "+cert);
                logger.debug("cert extensions ")
                logger.debug(cert.extensions)
                logger.debug("cert extensions[......] "+cert.extensions['1.2.3.4.5.6.7.8.1'])
                if(cert && cert.extensions && cert.extensions['1.2.3.4.5.6.7.8.1']) {
                    logger.debug("reached line 324 member")
                    let attr_string=cert.extensions['1.2.3.4.5.6.7.8.1'];
                    let attr_object = JSON.parse(attr_string);
                    let attrs = attr_object.attrs;
                    logger.debug("attributes: "+attrs)
                }

来自chaincode部分：这是chaincode中的代码

attrvalue,status,_:=cid.GetAttributeValue(stub,"hf.Registrar.Roles")
    fmt.Printf("attr Value: %s status : %t", attrvalue ,status)
    fmt.Println("attr Value: %s status : %t", attrvalue ,status)

来自节点部分： Cert.extension是

 { keyUsage: 'Digital Signature',
  basicConstraints: 'CA:FALSE',
  subjectKeyIdentifier: 'F3:66:26:E7:0D:1A:15:E9:F0:40:6F:FF:17:A8:5C:D3:CE:B8:4C:50',
  authorityKeyIdentifier: 'keyid:8D:0F:3C:42:48:8D:31:FE:72:06:99:4D:CE:1D:25:4E:A1:8C:DA:47:85:24:73:51:91:D4:CF:93:D6:7D:48:B2' }

问题已解决步骤

将https://github.com/hyperledger/fabric-sdk-node/tree/release/fabric-ca-client/lib/FabricCAClientImpl.js粘贴到node_modules / fabric-ca-client / lib
从主分支克隆fabric-ca并提供make clean＆amp; make docker
来自主分支的克隆结构

使用Hyperledger-Fabric进行基于属性的访问控制
