Urban Airship Server API - Java客户端实例

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。
