Question

我正在尝试使商业论文教程适应定制合同。更改合同名称后，就无法实例化它。

在商业文件/组织/ magnetocorp / contract / lib中，我更新了paper.js来替换：

    static getClass() {
        return 'org.papernet.commercialpaper';
    }

...和

    static getClass() {
        return 'org.papernet.commercialpapertest';
    }

类似地，在商业文件/组织/ magnetocorp / contract / lib中，我更新了papercontract.js来替换：

    constructor() {
        // Unique name when multiple contracts per chaincode file
        super('org.papernet.commercialpaper');
    }

...和：

    constructor() {
        // Unique name when multiple contracts per chaincode file
        super('org.papernet.commercialpapertest');
    }

然后，我从以下位置更改了实例化命令：

docker exec cliMagnetoCorp peer chaincode instantiate -n papercontract -v 0 -l node -c '{"Args":["org.papernet.commercialpaper:instantiate"]}' -C mychannel -P "AND ('Org1MSP.member')"

...到：

docker exec cliMagnetoCorp peer chaincode instantiate -n papercontract -v 0 -l node -c '{"Args":["org.papernet.commercialpapertest:instantiate"]}' -C mychannel -P "AND ('Org1MSP.member')"

在删除couchdb数据库，停止然后删除所有容器以及从头重新运行该示例时，这些更改导致实例化失败，并显示Contract name is not known：

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg transaction returned with failure: Error: Contract name is not known: org.papernet.commercialpapertest

这是docker日志：

列出已安装的合同表明已安装合同：

Get installed chaincodes on peer:
Name: papercontract, Version: 0, Path: /opt/gopath/src/github.com/contract, Id: a766e52585dbf1c0c9b725a72e66bd0e3f50f83da8641c9a4b4d6aebd6b85777

列出已实例化的合同表明未实例化：

Get instantiated chaincodes on channel mychannel:

似乎原始合同名称也设置在其他位置？如果是这样，我无法通过VS Code中的“查找文件”搜索来找到它。

非常感谢您的帮助。

似乎您没有更改package.json papercontract中的合同名称，因为该合同已安装在对等方上，并具有详细名称：papercontract, Version: 0

实例化测试合同失败，合同名称未知
