Question

我可以通过下面的命令行命令成功添加参与者。

Exception happened during processing of request from ('127.0.0.1', 40366)
Traceback (most recent call last):
File "/usr/lib/python3.5/socketserver.py", line 625, in process_request_thread

File "/usr/local/lib/python3.5/dist-packages/gevent/_socket3.py", line 229, in makefile
MemoryError

然而，当我尝试javascript API时，我收到此错误。

错误：尝试查询业务网络时出错。错误：链代码错误（状态：500，消息：错误：ID为'$ sysregistries'的集合中具有ID'Participant：org.acme.health'的对象不存在）在channel.queryByChaincode.then.catch（/home/sara/health-network/angular-app/node_modules/composer-connector-hlfv1/lib/hlfconnection.js:809:34）在

这是我的javascript代码

composer participant add -c admin@health-network -d '{"$class": "org.acme.health.Patient", "patientId": "10", "firstName": "Mae", "lastName": "smith", "email": "smith@gmail.com"}'

我的.cto文件中有一个名为'Patient'的参与者。

@ethertest，我已将您的代码格式化如下。希望它有效。

const BusinessNetworkConnection = require('composer-client').BusinessNetworkConnection;
let businessNetworkConnection = new BusinessNetworkConnection();

return businessNetworkConnection.connect('admin@health-network')
.then((bconnect) => {
    let bfactory = bconnect.getFactory();

    return Promise.all([businessNetworkConnection.getParticipantRegistry('org.acme.health.Patient'), bfactory]);
})
.then((participantRegistry1) => {
    participantRegistry = participantRegistry1[0];
    bfactory = participantRegistry1[1];

    let participant = bfactory.newResource('org.acme.biznet', 'Patient', 'patient1');
    participant.firstName = 'Bob';
    participant.lastName = 'Miller';
    return participantRegistry.add(participant);
})
.then(() => {
    return businessNetworkConnection.disconnect();
})
.catch((error) => {
    console.error(error);
    process.exit(1);
});
