Urban Airship Server API - Java客户端实例

本文链接：/article/1416021.html
今天在看Urban Airship的server端的API，Urban Airship官方网站上推荐了一个第三方的开源库http://bitbucket.org/sullis/urbanairship-java/，但是在经过简单测试后还是发现了一些问题，并且这个库好像也不是很活跃。为了看看Urban Airship的server端API怎么用，自己还是决定自己写个小程序试试看。
今天的测试由于涉及从Urban Airship向Android设备发送消息，所以这里假定已经有Android设备或者模拟器安装了可以接收消息的native app，具体步骤可以参考我的前一篇博客（http://blog.csdn.net/kongxx/article/details/8155916）。
下面开始今天的测试

1. 首先创建一个工程，这里还是使用maven来创建工程

mvn archetype:generate -DgroupId=urbanairship.server -DartifactId=urbanairship-server -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

2. 修改pom.xml文件如下

<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://maven.apache.org/POM/4.0.0"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> 
	<modelVersion>4.0.0</modelVersion>
	<groupId>urbanairship.server</groupId>
	<artifactId>urbanairship-server</artifactId>
	<packaging>jar</packaging>
	<version>1.0-SNAPSHOT</version>
	<name>urbanairship-server</name>
	<url>http://maven.apache.org</url>

	<dependencies>
		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
			<version>4.2.1</version>
		</dependency>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.8.1</version>
			<scope>test</scope>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>1.6</source>
					<target>1.6</target>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

3. 创建一个测试类Test，注意替换其中的username， password和apid。

package urbanairship.server;

import java.io.UnsupportedEncodingException;
import java.util.logging.Level;
import java.util.logging.Logger;

import org.apache.http.Header;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.StatusLine;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicHeader;
import org.apache.http.util.EntityUtils;

public class Test {

	private static Logger logger = Logger.getLogger(Test.class.getName());
	
	private static final String username = "This should be Application Key";
	private static final String password = "This should be Application Master Secret";
	private static final String apid = "This should be your APID of your android device";
	
	public static void main(String[] args) throws Exception {
		StringBuffer sb = new StringBuffer();
		sb.append("{\"android\": {\"alert\": \"hello world\"}, \"apids\": [\""+apid+"\"]}");
		String path = "https://go.urbanairship.com/api/push/";
		
		DefaultHttpClient httpClient = new DefaultHttpClient();
		httpClient.getCredentialsProvider().setCredentials(AuthScope.ANY,
				new UsernamePasswordCredentials(username, password));
		
		HttpPost httpPost = new HttpPost(path);
		httpPost.setHeader("Accept", "application/json");
		httpPost.setEntity(new JsonEntity(sb.toString()));
		logger.log(Level.INFO, "executing request: " + httpPost.getRequestLine());

		HttpResponse response = httpClient.execute(httpPost);
		
		StatusLine status = response.getStatusLine();
		int statusCode = status.getStatusCode();
		logger.log(Level.INFO, ""+statusCode);
		
		HttpEntity responseEntity = response.getEntity();
		logger.log(Level.INFO,  EntityUtils.toString(responseEntity));

	}

	static private class JsonEntity extends StringEntity {

		public JsonEntity(String jsonString) throws UnsupportedEncodingException {
			super(jsonString, "UTF-8");
		}

		@Override
		public Header getContentType() {
			Header h = new BasicHeader("Content-Type", "application/json");
			return h;
		}

	}
}

4. 测试，首先运行模拟器，然后运行可以接收message的android native app，最后运行上面的测试类，稍等片刻就会在设备或者模拟器上看到消息了。
