如果我放入 OpcUaClientConfigBuilder 中的证书错误，则错误会无限出现，这会使 opcua 服务器上的流量变大。
一段时间后，连接数变得如此之大，导致成功连接的客户端由于服务器流量而无法收到数据。
错误是：
Failed to connect to OPC UA server.

For reference my code is this
private static CompletableFuture createClient(字符串主机，整数端口，字符串用户名， 字符串密码、字符串 certPath、字符串 keyPath、字符串 applicationUri、字符串 securityPolicy) { // 创建网址 String url = String.format("opc.tcp://%s:%s", 主机, 端口);
return DiscoveryClient.getEndpoints(url).thenCompose(endpoints -> {
try {
// fetch EndpointDescription
EndpointDescription endpointDescription = findBest(endpoints);
MessageSecurityMode messageSecurityMode = endpointDescription.getSecurityMode();
// set security policy
String securityPolicyUri = endpointDescription.getSecurityPolicyUri();
UserTokenPolicy[] userTokenPolicies = endpointDescription.getUserIdentityTokens();
if (securityPolicy != null) {
securityPolicyUri = "http://opcfoundation.org/UA/SecurityPolicy#" + securityPolicy;
for (int i = 0; i < userTokenPolicies.length; i++) {
UserTokenPolicy userTokenPolicy = userTokenPolicies[i];
userTokenPolicies[i] = new UserTokenPolicy(userTokenPolicy.getPolicyId(),
userTokenPolicy.getTokenType(), userTokenPolicy.getIssuedTokenType(),
userTokenPolicy.getIssuerEndpointUrl(), securityPolicyUri);
}
}
// recreate EndpointDescription as returned EndpointDescription from server might not match the specifications
EndpointDescription endpointDescriptionModified = new EndpointDescription(url,
endpointDescription.getServer(), endpointDescription.getServerCertificate(),
MessageSecurityMode.SignAndEncrypt, securityPolicyUri, userTokenPolicies,
endpointDescription.getTransportProfileUri(), endpointDescription.getSecurityLevel());
// create OpcUaClientConfigBuilder
OpcUaClientConfigBuilder cfg = new OpcUaClientConfigBuilder();
// set end point
cfg.setEndpoint(endpointDescriptionModified);
// set user name and password
if (username != null & (certPath == null || keyPath == null)) {
cfg.setIdentityProvider(new UsernameProvider(username, password));
}
// set certificates
if (certPath != null && keyPath != null) {
X509IdentityProvider x509IdentityProvider = new X509IdentityProvider(certPath, keyPath);
X509Certificate cert = x509IdentityProvider.getCertificate();
KeyPair keyPair = new KeyPair(cert.getPublicKey(), x509IdentityProvider.getPrivateKey());
if (username != null) {
cfg.setCertificate(cert).setKeyPair(keyPair).setIdentityProvider(x509IdentityProvider)
.setIdentityProvider(new UsernameProvider(username, password));
} else {
cfg.setCertificate(cert).setKeyPair(keyPair).setIdentityProvider(x509IdentityProvider);
}
}
// set ApplicationUri
if (applicationUri != null) {
cfg.setApplicationUri(applicationUri);
}
return CompletableFuture.completedFuture(OpcUaClient.create(cfg.build()));
} catch (final UaException e) {
CompletableFuture<OpcUaClient> failedFuture = new CompletableFuture<>();
failedFuture.completeExceptionally(e);
return failedFuture;
}
});
}
I am expecting if there is some property or something so that I can limit the retry of the connection the server. if OpcUaClientConfigBuilder has some properties. I explored the possible methods of that builder but unable to tackle that error.
客户端将自动尝试重新连接，直到您拨打
disconnect()它会以指数方式放弃尝试，直到每约 16 秒尝试一次。这是不可配置的。
一段时间后，连接数变得如此之大，导致成功连接的客户端由于服务器流量而无法收到数据。
我不知道你想在这里说什么。
