SubscribeChannelBackups - 订阅通道备份

SubscribeChannelBackups 允许客户端订阅所有通道备份的状态更新。

gRPC请求 - ChannelBackupSubscription

无字段。

gRPC响应 - ChanBackupSnapshot (Streaming)

字段如下：

• single_chan_backups: 新的单通道备份集，ChannelBackups
• multi_chan_backup ：当前的多通道备份

示例代码

Python示例代码

>>> import codecs, grpc, os
>>> import rpc_pb2 as ln, rpc_pb2_grpc as lnrpc
>>> macaroon = codecs.encode(open('LND_DIR/data/chain/bitcoin/simnet/admin.macaroon', 'rb').read(), 'hex')
>>> os.environ['GRPC_SSL_CIPHER_SUITES'] = 'HIGH+ECDSA'
>>> cert = open('LND_DIR/tls.cert', 'rb').read()
>>> ssl_creds = grpc.ssl_channel_credentials(cert)
>>> channel = grpc.secure_channel('localhost:10009', ssl_creds)
>>> stub = lnrpc.LightningStub(channel)
>>> request = ln.ChannelBackupSubscription()
>>> for response in stub.SubscribeChannelBackups(request):
        print(response)
{ 
    "single_chan_backups": <ChannelBackups>,
    "multi_chan_backup": <MultiChanBackup>,
}

JavaScript示例代码

> var grpc = require('grpc');
> var lnrpc = grpc.load('rpc.proto').lnrpc;
> process.env.GRPC_SSL_CIPHER_SUITES = 'HIGH+ECDSA'

> var sslCreds = grpc.credentials.createSsl(lndCert);
> var macaroonCreds = grpc.credentials.createFromMetadataGenerator(function(args, callback) {
    var macaroon = fs.readFileSync("LND_DIR/data/chain/bitcoin/simnet/admin.macaroon").toString('hex');
    var metadata = new grpc.Metadata()
    metadata.add('macaroon', macaroon);
    callback(null, metadata);
  });
> var creds = grpc.credentials.combineChannelCredentials(sslCreds, macaroonCreds);
> var lightning = new lnrpc.Lightning('localhost:10009', creds);
> var request = {} 
> var call = lightning.subscribeChannelBackups(request)
> call.on('data', function(response) {
    // A response was received from the server.
    console.log(response);
  });
> call.on('status', function(status) {
    // The current status of the stream.
  });
> call.on('end', function() {
    // The server has closed the stream.
