Question

使用Hyperledger Composer V0.12使用以下代码调用deploy函数，该代码返回一个成功的＆＃39;结果：

/**
 * Deploys a new BusinessNetworkDefinition to the Hyperledger Fabric. The connection must be connected for this method to succeed.
 * @param {express.req} req - the inbound request object from the client
 *  req.body.myArchive: _string - string name of object
 *  req.body.deployOptions: _object - string name of object
 * @param {express.res} res - the outbound response object for communicating back to client
 * @param {express.next} next - an express service to enable post processing prior to responding to the client
 * returns composerAdmin.connection - either an error or a connection object
 * @function
 */
exports.deploy = function(req, res, next) {

let newFile = path.join(path.dirname(require.main.filename),'network/dist',req.body.myArchive);
let archiveFile = fs.readFileSync(newFile);

let adminConnection = new composerAdmin.AdminConnection();

return BusinessNetworkDefinition.fromArchive(archiveFile)
    .then(function(archive) {
        adminConnection.connect(config.composer.connectionProfile, config.composer.adminID, config.composer.adminPW)
        .then(function(){
            adminConnection.deploy(archive)
                .then(function(){
                    console.log('business network '+req.body.myArchive+' deployed successful: ');
                    res.send({deploy: req.body.myArchive+' deploy succeeded'});
                })
                .catch(function(error){
                    console.log('business network '+req.body.myArchive+' deploy failed: ',error);
                    res.send({deploy: error});
                    });
            });
        });
};

但是，当我完成以下过程时：

启动docker镜像，使用cli部署网络
ping
undeploy
平
部署
平

我得到以下结果：

这表明作曲家部署功能实际上并未部署网络，即使我似乎从部署服务收到成功的完成消息。请帮帮忙？

取消部署业务网络时，它所做的只是将业务网络标记为无法访问。它仍然部署并仍在运行。原因是目前Hyperledger结构没有提供关闭实例化链代码的机制。所以我们所能做的就是将其标记为无法使用。部署API和命令是启动和运行业务网络的旧方法。新方法是安装/启动组合。部署报告成功的原因是它必须决定安装和启动命令报告的错误，以便继续以Hyperledger Fabric的方式以预期的方式工作。因此，尽管它报告了部署成功，但由于它已经部署，它实际上什么都不做。
