从v1.1.1开始，应用链客户端SCS也支持使用了和以太坊类似的交互式命令行。用户可以在命令行（console）中执行内置的JAVA script命令或者利用脚本（script），输出结果显示在命令行中。这里使用的chain3对象，是MOAC参考以太坊，而开发的一套javascript库，目的是让应用程序能够与MOAC的VNODE和SCS节点进行通信。注意，这里有两层，moac启动了一个MOAC VNODE节点，console参数开启了一个javascript的控制台，这个控制台注入了chain3.js这个库，以使我们可以通过chain3对象与MOAC SCS不同应用链节点做交互。

SCS和用户交互的命令行界面

MOAC 应用链节点的客户端（SCS）构建了一个可以和用户交互的JavaScript命令行界面。启动这个命令行首先需要启动一个SCS客户端，并确保打开RPC。

$ ./scsserver –rpc –rpcport 8546

然后使用下面命令

$ scsserver attach

scs客户端会去连接一个已经运行的SCS节点并显示命令行界面，默认路径为./scsdata。

$ scsserver attach ./scsdata/scs.ipc

请注意，默认情况下，MOAC SCS节点不会启动RPC服务。

交互式使用示例

以下是主要的两个交互式命令功能包：scs和appchain。

scs

主要提供SCS节点相关信息，可以使用RPC方法与应用链通讯，具体方法可以参考 JSONRPC 接口。

scs.getSCSId

获取SCS的ID

输入参数：无

示例如下：

> scs.getSCSId()
"0x76449055dc3cf91090c11f7c544b60363bf896cb"

scs.getAppChainList

返回SCS接入的应用链列表。

输入参数：无

示例如下：

scs.sendRawTransaction

发送已加签好的交易

输入参数：: 加签交易数据

示例如下：

> scs.sendRawTransaction("0xf86a33808504a817c8008094aa4c98c7efb244f4104bf3bb437cd761df4e648c8084d826f88f018081efa0ec2607997ed3d35adf7821983f996b37495b8d42b47286ec74d166d4f51b5a27a071de43031ce69aaed8c1e66b19f9a5953364503ba2b67599ab218117b3182a30")

注意

MOAC SCS's JSRE 和以太坊的客户端一样采取了Otto JS VM 虚拟机并具有以下限制:

"use strict" 语句可以编译通过，但没有相应效果。正则表达式引擎（re2 / regexp）与ECMA5规范不完全兼容。注意，Otto的另一个已知限制（即缺少计时器）已得到解决。以太坊JSRE同时实现setTimeout和setInterval。除此之外，控制台还提供admin.sleep（seconds）以及“ blocktime sleep”方法admin.sleepBlocks（number）。
