Question

我目前有一个正在运行的基于Kafka的超级账本在docker上运行。

完整的容器列表如下：

2个订购者
2个同龄人
1x证书颁发机构
3个Zookeeper
4个kafka节点
1个cli工具

我已通过以下命令使用cli成功创建了一个频道

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

/**

public class JavaFXApplication319 extends Application
{

    @Override
    public void start(Stage primaryStage)
    {
        String javaString = "/* HelloWorld.java\n"
                + " */\n"
                + "\n"
                + "public class HelloWorld\n"
                + "{\n"
                + " public static void main(String[] args) {\n"
                + "     System.out.println(\"Hello World!\");\n"
                + " }\n"
                + "}";

        String htmlString = "<!DOCTYPE html>\n"
                + "<html>\n"
                + "<head>"
                + "<link href=\"" + getClass().getResource("prism.css") + "\"" + " rel=\"stylesheet\"" + " type=\"text/css\"" + " />\n"
                + "<script src=\"" + getClass().getResource("prism.js") + "\"" + " type=\"text/javascript\"" + "></script>\n"
                + "</head>"
                + "<body>\n"
                + "\n"
                + "<h1>My First Heading</h1>\n"
                + "\n"
                + "<p>My first paragraph.</p>\n"
                + "\n"
                + "<pre>"
                + " <code class=\"language-java\">\n"
                + javaString
                + "</code>\n"
                + "</pre>\n"
                + "</body>\n"
                + "</html>";

        WebView webView = new WebView();
        WebEngine engine = webView.getEngine();
        engine.setJavaScriptEnabled(true);
        engine.loadContent(htmlString);

        StackPane root = new StackPane(webView);

        Scene scene = new Scene(root, 500, 400);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        launch(args);
    }

}

我可以使用以下命令看到对等方：

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

/**
 *
 * @author blj0011
 */
public class JavaFXApplication319 extends Application
{

    @Override
    public void start(Stage primaryStage)
    {
        String htmlStringPreCode = "<!DOCTYPE html>\n"
                + "<html>\n"
                + "<head>\n"
                + "</head>\n"
                + "<body>\n"
                + "This is a Test\n"
                + "</body>\n"
                + "</html>\n";

        String htmlString = "<!DOCTYPE html>\n"
                + "<html>\n"
                + "<head>"
                + "<link href=\"" + getClass().getResource("prism.css") + "\"" + " rel=\"stylesheet\"" + " type=\"text/css\"" + " />\n"
                + "<script src=\"" + getClass().getResource("prism.js") + "\"" + " type=\"text/javascript\"" + "></script>\n"
                + "</head>"
                + "<body>\n"
                + "\n"
                + "<h1>My First Heading</h1>\n"
                + "\n"
                + "<p>My first paragraph.</p>\n"
                + "\n"
                + "<pre>"
                + " <code class=\"language-html\">\n"
                + htmlStringPreCode
                + "</code>\n"
                + "</pre>\n"
                + "</body>\n"
                + "</html>";

        WebView webView = new WebView();
        WebEngine engine = webView.getEngine();
        engine.setJavaScriptEnabled(true);
        engine.loadContent(htmlString);

        StackPane root = new StackPane(webView);

        Scene scene = new Scene(root, 500, 400);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        launch(args);
    }

}

然后我要这样初始化并实例化我的链码

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/msp/users/Admin@company/msp" peer0.company peer channel create -o orderer0.company:7050 -c messagebus -f /etc/hyperledger/configtx/channel.tx

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/msp/users/Admin@company/msp" peer0.company peer channel join -b messagebus.block

如最后一行所示，访问被拒绝。我也无法将Java SDK客户端加入频道并收到类似的访问被拒绝错误。

我在peer0容器中看到以下日志：

docker exec cli peer channel list

2019-01-07 16:54:41.784 UTC [channelCmd] InitCmdFactory -> INFO 003 Endorser and orderer connections initialized
Channels peers has joined: 
messagebus

这使我相信对等方未正确设置...但是它能够成功创建通道。

任何指针将不胜感激

Hyperledger-对等体加入频道后无法实例化链码
