超级作曲作者部署示例代码失败

当前正在使用最新版本的hyperledger开发环境，并且正在通过管理服务进行工作。 admin的示例代码 - >部署被记录为：超级作曲作者部署示例代码失败

// Deploy a Business Network Definition 
var adminConnection = new AdminConnection(); 
var businessNetworkDefinition = BusinessNetworkDefinition.fromArchive(myArchive); 
return adminConnection.deploy(businessNetworkDefinition) 
.then(function(){ 
    // Business network definition deployed 
}) 
.catch(function(error){ 
    // Add optional error handling here. 
});

在代码提供，如BusinessNetworkDefinition不是作曲家管理员节点模块的一部分的第二行失败。我有两个创建BusinessNetworkDefinition的选项，一个是使用composer-client。这种失败，出现以下消息：TypeError: composerClient.BusinessNetworkDefinition is not a constructor 用于此尝试的代码总结如下：

'use strict'; 
var fs = require('fs'); 
var path = require('path'); 
var composer = require('composer-admin'); 
var composerClient = require('composer-client'); 
var composerCommon = require('composer-common'); 

    var businessNetworkDefinition = new composerClient.BusinessNetworkDefinition();

另一种选择是使用作曲家常见，它失败，出现以下消息：TypeError: businessNetworkDefinition.fromArchive is not a function 代码用于此尝试是：

var fs = require('fs'); 
var path = require('path'); 
var composer = require('composer-admin'); 
var composerClient = require('composer-client'); 
var composerCommon = require('composer-common'); 

    var net_identifier = "[email protected]"; 
    var net_description = "Z2B network"; 
    var net_package = require("../../../../network/package.json"); 
    var net_readme = "../../../../README.md"; 

    var businessNetworkDefinition = new composerCommon.BusinessNetworkDefinition(net_identifier, net_description, net_package, net_readme); 
    var archive = businessNetworkDefinition.fromArchive(req.body.myArchive);

其中req.body.myArchive是归档文件的名称在fromArchive方法可以使用。检查通过new命令创建的BusinessNetworkDefinition显示以下内容：

object property: modelManager 
object property: aclManager 
object property: queryManager 
object property: scriptManager 
object property: introspector 
object property: factory 
object property: serializer 
object property: metadata

于是，两个问题：

一：什么是用new命令创建和
二：如何正确地创建一个BusinessNetworkDefinition对象，其中作为fromArchive()的函数呢？

在hyperledger作曲家文档中的示例代码是有缺陷的。以下是将成功执行业务网络部署的代码。（1）所需定义：

let fs = require('fs'); 
let path = require('path'); 
let composerAdmin = require('composer-admin'); 
const BusinessNetworkDefinition = require('composer-common').BusinessNetworkDefinition;

以下写为在一个的NodeJS导出，可路由的常规和已通过从客户（浏览器）的测试。客户端以网络名义进行部署。文件布局是：

root/network/dist/network-archive-file.bna

（2）阅读档案文件，并创建一个管理员连接：

/** 
* 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();

（3）调用（异步）fromArchive功能，然后部署fromArchive结果调用。

return BusinessNetworkDefinition.fromArchive(archiveFile) 
    .then(function(archive) { 
     adminConnection.connect(config.composer.connectionProfile, config.composer.adminID, config.composer.adminPW) 
     .then(function(){ 
      adminConnection.deploy(archive)

（4）。回应（基于浏览器）的请求：

  .then(function(){ 
       console.log('business network deploy successful: '); 
       res.send({deploy: 'succeeded'}); 
      }) 
      .catch(function(error){ 
       console.log('business network deploy failed: ',error); 
       res.send({deploy: error}); 
       });

...（5）和任何人复制所有的代码，有几个结束括号：

 }); 
    }); 
};
