Example 80 with ArrayNode

use of org.apache.flink.shaded.jackson2.com.fasterxml.jackson.databind.node.ArrayNode in project indy by Commonjava.

the class IndyZabbixApi method getHost.

/**
     *
     * @param name
     * @return hostid
     */
public String getHost(String name) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    ObjectNode jsonNode = mapper.createObjectNode();
    ArrayNode arrayNode = mapper.createArrayNode();
    arrayNode.add(name);
    jsonNode.put("host", arrayNode);
    Request request = RequestBuilder.newBuilder().method("host.get").paramEntry("filter", jsonNode).build();
    JsonNode response = call(request);
    if (response.get("result").isNull() || response.get("result").get(0) == null) {
        return null;
    }
    return response.get("result").get(0).get("hostid").asText();
