As a restful client, I can successfully connect to the server using the Postman software without any certification or security setting. (I receive the correct response from the server) But when I call it using java Program, it throws Exception below:
javax.net.ssl.SSLHandshakeException: No subject alternative names matching IP address 192.168.12.125 found
I also looked at this link that didn't solve my problem.
here is java code I used:
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import java.io.Serializable;
public class CallService implements Serializable {
private String uri = "https://192.168.12.125:443/ssdpn";
private Client client;
private WebResource webResource;
public void sendRequest(String input) {
try {
client = Client.create();
webResource = client.resource(uri);
String requestBody = prepareJSONFormatRequest(input);
ClientResponse response =
webResource.path("/Service205")
.header("trackId", "1001")
.header("serviceId", "Service205")
.post(ClientResponse.class, requestBody);
String result = response.getEntity(String.class);
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
private String prepareJSONFormatRequest(String input) {
StringBuilder request = new StringBuilder();
request.append("{ ").append("\"SerialNumber\":\"").append(input).append("\" }");
return request.toString();
}
}
in the java program, I also use no certificate (As I do in Postman call). could anybody help me to find where does the problem lies?
I fixed by calling this method in the constructor:
private void fixHttpsHandler() {
try {
TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
}
};
SSLContext mySSLContext = SSLContext.getInstance("TLSv1.3");
mySSLContext.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(mySSLContext.getSocketFactory());
HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
} catch (Exception ex) {
ex.printStackTrace();
}
}
then
public class CallService implements Serializable {
public CallService() {
try {
fixHttpsHandler();
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
}
