只查询Hyperledger Fabric的部分属性
我已经构建了 Hyperledger Fabric 通道并且运行良好。但是，我只想从具有这样的数据结构的 Hyperledger 中获取一些属性，
[
{
"name": "name-1",
"class": "IV-A",
"address": "dummy st.",
"handphone": "xxx-xxx-xxx-xxx",
"status": "inactive"
},
{
"name": "name-2",
"class": "IV-A",
"address": "dummy st. 7th",
"handphone": "xxx-xxx-xxx-xxx",
"status": "active"
},...
]
我只想获取一些属性（名称、地址和状态），所以我们可以像这样获得返回
[
{
"name": "name-1",
"address": "dummy st.",
"status": "inactive"
},
{
"name": "name-2",
"address": "dummy st. 7th",
"status": "active"
},...
]
是否可以通过 hyperledger 获取这些属性直接不使用couchdb？我知道如果我们使用 couchdb，我们只需要在“emit()”中使用一些查询创建视图，但是有没有办法使用链码或选择器在超级账本中获取该视图？
先感谢您。
i've build Hyperledger Fabric channel and it was running well. But, i wanna get just some attributes only from that Hyperledger that have data structure like this
[
{
"name": "name-1",
"class": "IV-A",
"address": "dummy st.",
"handphone": "xxx-xxx-xxx-xxx",
"status": "inactive"
},
{
"name": "name-2",
"class": "IV-A",
"address": "dummy st. 7th",
"handphone": "xxx-xxx-xxx-xxx",
"status": "active"
},...
]
i wanna get just some attributes (name, address, and status), so we can get the return like this
[
{
"name": "name-1",
"address": "dummy st.",
"status": "inactive"
},
{
"name": "name-2",
"address": "dummy st. 7th",
"status": "active"
},...
]
is it possible to get those attributes via hyperledger directly without using couchdb? i know if we use couchdb we just need to create the view with some query in the "emit()", but is there any way to get that in hyperledger using chaincode or selector?
Thank you in advance.

我不确定您的 Hyperledger Fabric 环境和数据。
但是您可以查看这个链码。
或者如果您可以使用“调用函数”，您可以返回您想要的值。
I'm not sure about your Hyperledger Fabric environment and data.
But you can check out this chaincode.
OR if you are OK to use 'invoke function', you can return value what you want.
