可以使用与部署它不同的链码访问世界状态变量吗? [英] Can a World State variable be accessed by a chaincode different from the one that deployed it?

问题描述

如果链码A将变量V存储到世界状态，那么另一个链码B可以访问该变量V吗?

If a chaincode A stores a variable V to the World State can this variable V be accessed by another chaincode B?

换句话说，世界状态访问中的变量是否受到保护?

In other words, are variables in the World State access protected?

如果不可能，如何使链码B从链码A中读取变量(我的用例需要它)?

If it is not possible, how can I make chaincode B read the variables from chaincode A (I need it for my use case)?

推荐答案

不，某些链码A所存储的变量只能由相同的链码A访问.因此，如果链码B尝试访问变量V，则访问权限为否认.

No, variables stored by some chaincode A can only be accessed by the same chaincode A. So if a chaincode B tries to access the variable V, access will be denied.

如果要访问此类变量(因为用例需要链代码之间的互连)，则可以使用

If you wanted to access such variables (because your use case requires interconnection between chaincodes) you can invoke/query chaincode A from chaincode B using this.
