出现错误：DiscoveryService：主通道错误：访问被拒绝

问题描述 投票：0回答：1

我正在尝试使用通过网关连接到结构网络后获得的合约对象来提交交易。 网关已成功建立，但在尝试使用 gateway.getNetwork() 方法时出现此错误：

2024-04-24T14:55:04.414Z - error: [DiscoveryResultsProcessor]: parseDiscoveryResults[mainchannel] - Channel:mainchannel received discovery error:access denied

throw Error(`DiscoveryService: ${this.service.name} error: ${result.error.content}`);

                      ^

下面是给出错误的函数：

const connection = async (ccp, wallet, userName) => {
    const gateway = new Gateway()
    await gateway.connect(ccp, {
        wallet,
        identity: userName,
        discovery: { enabled: true, asLocalhost: true } // using asLocalhost as this gateway is using a fabric network deployed locally
    });

    const network = await gateway.getNetwork(process.env.CHANNEL);
    console.log(network)

    // Get the contract from the network.
    // const contract = network.getContract(process.env.CONTRACT);
    // console.log(contract)

    // const result = await contract.submitTransaction('CreateEvidence', "xyxyx", userName, "100", "Hacking", "xss.png", "png", "zzzzz")
    // console.log(result)
}

尝试将发现链接到 false 并且 gateway.getNetwork() 和 network.getContract() 有效，但在contract.submitTransaction()

产生以下错误

对于 Hyperledger Fabric v2.4 及更高版本（包括 v2.5），您应该使用较新的 Fabric Gateway 客户端 API。旧版 SDK（针对 Fabric v2.2 及更早版本）不再受支持或主动维护。话虽如此，旧版 SDK 应该可以继续正常工作。

您的错误消息表明您使用的客户端身份没有访问该频道的权限。您需要确保在连接网关时配置正确的凭据。

在旧客户端中禁用服务发现意味着它需要在其本地连接配置文件中定义足够的节点（对等点和排序者）才能成功与 Fabric 网络进行交易。这包括足够多的节点来满足背书要求，以及提交背书交易的订购者。通常，客户端使用服务发现从任何网络对等方获取此信息。使用较新的 Fabric Gateway 客户端 API，这是不必要的，因为客户端只需要与单个网络对等点交互。
