Policy provides a centralized environment for the creation and management of easily-updatable conditional rules. It enables users to validate policies and rules, identify and resolve overlaps and conflicts, and derive additional policies where needed. The following operations are supported by the policy API: * Create policies on the PAP * Update policies on the PAP * Delete policies on the PAP or PDP * Push policies from the PAP to the PDP * List policies on the PDP * Get config data of policies on the PDP * Create Dictionary Items * Update Dictionary Items * Retrieve Dictionary Items * Import Micro Services Models * Retrieve Metrics for policy counts from PDP and PAP POLICY Engine Services ^^^^^^^^^^^^^^^^^^^^^^ .. image:: PolicyEngineApiList.png POLICY API Details ^^^^^^^^^^^^^^^^^^ .. swaggerv2doc:: api-docs.json Examples ^^^^^^^^ **SAMPLE JAVA CLIENT CODE** .. code-block:: java :caption: Get Config Example :linenos: package org.onap.policyEngine; import java.util.Collection; import org.onap.policy.api.ConfigRequestParameters; import org.onap.policy.api.PolicyConfig; import org.onap.policy.api.PolicyEngine; public class GetConfigSample { public static void main(String[] args) throws Exception { PolicyEngine pe = new PolicyEngine("config.properties"); ConfigRequestParameters configRequestParams = new ConfigRequestParameters(); configRequestParams.setPolicyName(".*"); Collection configs = pe.getConfig(configRequestParams); for (PolicyConfig config: configs){ System.out.println(config.getPolicyConfigMessage()); System.out.println(config.getPolicyConfigStatus()); } } } .. code-block:: java :caption: Create Config FIrewall Policy Example :linenos: package org.onap.policyEngine; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.io.StringReader; import java.nio.file.Path; import java.nio.file.Paths; import java.text.SimpleDateFormat; import java.util.Date; import java.util.UUID; import javax.json.Json; import javax.json.JsonObject; import javax.json.JsonReader; import org.onap.policy.api.PolicyChangeResponse; import org.onap.policy.api.PolicyConfigType; import org.onap.policy.api.PolicyEngine; import org.onap.policy.api.PolicyParameters; import org.onap.policy.api.PolicyType; public class ConfigFirewallPolicyClient { static Boolean isEdit = false; public static void main(String[] args) { try{ PolicyEngine policyEngine = new PolicyEngine("config.properties"); PolicyParameters policyParameters = new PolicyParameters(); // Set Policy Type policyParameters.setPolicyConfigType(PolicyConfigType.Firewall); //required policyParameters.setPolicyName("MikeAPItesting.testConfigFirewallPolicy1607_1"); //required //policyParameters.setPolicyScope("MikeAPItesting"); //Directory will be created where the Policies are saved... this displays a subscope on the GUI policyParameters.setRequestID(UUID.randomUUID()); // Set Safe Policy value for Risk Type SimpleDateFormat dateformat3 = new SimpleDateFormat("dd/MM/yyyy"); Date date = dateformat3.parse("15/10/2016"); policyParameters.setTtlDate(date); // Set Safe Policy value for Guard policyParameters.setGuard(true); // Set Safe Policy value for Risk Level policyParameters.setRiskLevel("5"); // Set Safe Policy value for Risk Type policyParameters.setRiskType("PROD"); File jsonFile = null; String jsonRuleList = null; Path file = Paths.get("C:\\policyAPI\\firewallRulesJSON\\Config_FW_Sample.json"); jsonFile = file.toFile(); //buildJSON(jsonFile, jsonRuleList); policyParameters.setConfigBody(buildJSON(jsonFile, jsonRuleList).toString()); policyParameters.setConfigBodyType(PolicyType.JSON); // API method to create Policy or update policy PolicyChangeResponse response = null; if (!isEdit) { response = policyEngine.createPolicy(policyParameters); } else { response = policyEngine.updatePolicy(policyParameters); } if(response.getResponseCode()==200){ System.out.println(response.getResponseMessage()); System.out.println("Policy Created Successfully!"); }else{ System.out.println("Error!
