java 模拟ua,使用OPCFoundation/UA-Java项目工作OPC UA Simulator示例

我使用org.opcfoundation.ua.examples.SampleClient实用程序检查连接和样本值，但无法这样做。如果任何人有工作考试w.r.t请与代码一起分享。一旦这个工作，我需要在apache Nifi中配置这个设置来制作数据管道。

代码：

public class SampleClient {

public static final Locale ENGLISH = Locale.ENGLISH;

public static final Locale ENGLISH_FINLAND = new Locale("en", "FI");

public static final Locale ENGLISH_US = new Locale("en", "US");

public static final Locale FINNISH = new Locale("fi");

public static final Locale FINNISH_FINLAND = new Locale("fi", "FI");

public static final Locale GERMAN = Locale.GERMAN;

public static final Locale GERMAN_GERMANY = new Locale("de", "DE");

public static void main(String[] args)

throws Exception {

// if (args.length==0) {

// System.out.println("Usage: SampleClient [server uri]");

// return;

// }

//String url = /*args[0]*/"opc.tcp://uademo.prosysopc.com:53530/OPCUA/SimulationServer";

//String url = /*args[0]*/"opc.tcp://uademo.prosysopc.com:53530";

//String url = /*args[0]*/"opc.tcp://opcua.demo-this.com:51210/UA/SampleServer";

String url="opc.tcp://mfactorengineering.com:4840";

//String url="opc.tcp://commsvr.com:51234/UA/CAS_UA_Server";

//String url="opc.tcp://uademo.prosysopc.com:53530/OPCUA/SimulationServer";

//String url="opc.tcp://opcua.demo-this.com:51210/UA/SampleServer";

//String url="opc.tcp://opcua.demo-this.com:51211/UA/SampleServer";

//String url="opc.tcp://opcua.demo-this.com:51212/UA/SampleServer";

//String url="opc.tcp://demo.ascolab.com:4841";

//String url="opc.tcp://alamscada.dynu.com:4096";

System.out.print("SampleClient: Connecting to "+url+" .. ");

// CLIENT //

// Create Client

Application myApplication = new Application();

Client myClient = new Client(myApplication);

myApplication.addLocale(ENGLISH);

myApplication.setApplicationName(new LocalizedText("Java Sample Client", Locale.ENGLISH));

myApplication.setProductUri("urn:JavaSampleClient");

CertificateUtils.setKeySize(1024); // default = 1024

KeyPair pair = ExampleKeys.getCert("SampleClient");

myApplication.addApplicationInstanceCertificate(pair);

// The HTTPS SecurityPolicies are defined separate from the endpoint securities

myApplication.getHttpsSettings().setHttpsSecurityPolicies(HttpsSecurityPolicy.ALL);

// Peer verifier

myApplication.getHttpsSettings().setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

myApplication.getHttpsSettings().setCertificateValidator(CertificateValidator.ALLOW_ALL);

// The certificate to use for HTTPS

KeyPair myHttpsCertificate = ExampleKeys.getHttpsCert("SampleClient");

myApplication.getHttpsSettings().setKeyPair(myHttpsCertificate);

// Connect to the given uri

SessionChannel mySession = myClient.createSessionChannel(url);

// mySession.activate("username", "123");

mySession.activate();

//

/ EXECUTE //

// Browse Root

BrowseDescription browse = new BrowseDescription();

browse.setNodeId(Identifiers.RootFolder);

browse.setBrowseDirection(BrowseDirection.Forward);

browse.setIncludeSubtypes(true);

browse.setNodeClassMask(NodeClass.Object, NodeClass.Variable);

browse.setResultMask(BrowseResultMask.All);

BrowseResponse res3 = mySession.Browse(null, null, null, browse);

System.out.println(res3);

// Read Namespace Array

ReadResponse res5 = mySession.Read(

null,

null,

TimestampsToReturn.Neither,

new ReadValueId(Identifiers.Server_NamespaceArray, Attributes.Value, null, null)

);

String[] namespaceArray = (String[]) res5.getResults()[0].getValue().getValue();

System.out.println(Arrays.toString(namespaceArray));

// Read a variable

ReadResponse res4 = mySession.Read(

null,

500.0,

TimestampsToReturn.Source,

new ReadValueId(new NodeId(6, 1710), Attributes.Value, null, null)

);

System.out.println(res4);

res4 = mySession.Read(

null,

500.0,

TimestampsToReturn.Source,

new ReadValueId(new NodeId(6, 1710), Attributes.DataType, null, null)

);

System.out.println(res4);

/ SHUTDOWN /

mySession.close();

mySession.closeAsync();

//

}

}

@ CamilleG。你好，我已经取代了opc.tcp：//212.68.9.58：48401网址在SampleClient.java上面贴，我得到这个例外Bad_SecurityChecksFailed(代码= 0x80130000，说明=“Bad_SecurityChecksFailed(代码= 0x80130000，说明=”发生错误验证安全性。“)”)。请问您可以检查SampleClient java程序，看看我是否遗漏了任何东西 –

看起来与OPC UA证书有关的错误。最好的办法是下载一个OPC UA服务器并在本地PC上运行，然后连接到您的JAVA程序。 (一个来自统一自动化应该没问题：https：//www.unified-automation.com/downloads/opc-ua-servers.html) –
