I'm a newbie to mashape unirest, and I can't seem to figure out what I'm doing wrong.
I'm using maven to use unirest as a dependency, as so:
<dependencies>
<dependency>
<groupId>com.mashape.unirest</groupId>
<artifactId>unirest-java</artifactId>
<version>1.3.27</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.6</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpasyncclient</artifactId>
<version>4.0.2</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.3.6</version>
</dependency>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20140107</version>
</dependency>
</dependencies>
Next, I'm trying to use unirest to make an asyncronous call to my server using java anonymous callbacks.
import java.util.*;
import java.util.concurrent.Future;
import java.util.concurrent.CountDownLatch;
import java.util.concurrent.atomic.AtomicInteger;
import java.lang.*;
import java.io.*;
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.JsonNode;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.async.Callback;
import com.mashape.unirest.http.exceptions.UnirestException;
import com.mashape.unirest.http.options.Options;
public class CRDTClient {
private ArrayList<String> servers;
public AtomicInteger successCount;
public CRDTClient() {
servers = new ArrayList(3);
servers.add("http://localhost:3000");
servers.add("http://localhost:3001");
servers.add("http://localhost:3002");
}
public boolean put(long key, String value) {
final CountDownLatch countDownLatch = new CountDownLatch(servers.size());
successCount = new AtomicInteger();
for (final String serverUrl : servers) {
Future<HttpResponse<JsonNode>> future = Unirest.post(serverUrl + "/cache/{key}/{value}")
.header("accept", "application/json")
.routeParam("key", Long.toString(key))
.routeParam("value", value).asJson()
.asJsonAsync(new Callback<JsonNode>() {
public void failed(UnirestException e) {
System.out.println("The request has failed: " + serverUrl);
countDownLatch.countDown();
}
public void completed(HttpResponse<JsonNode> response) {
int code = response.getStatus();
if (code == 200) {
successCount.incrementAndGet();
}
countDownLatch.countDown();
}
public void cancelled() {
System.out.println("The request has been cancelled");
}
});
}
// Block the thread until all responses gotten
countDownLatch.await();
return (Math.round(successCount.floatValue() / servers.size()) == 1);
}
The error I get when I run
mvn clean package -e
is
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project client: Compilation failure
[ERROR] /Users/jonguan/Documents/SJSU/cmpe273/cmpe273-lab4/client/src/main/java/edu/sjsu/cmpe/cache/client/CRDTClient.java:[40,20] error: cannot find symbol

which turns out to be the line on .asJsonAsync
I tried importing all sorts of classes, but it doesn't seem to work.
