我跟隨了UA教程並獲得了我的APID,併成功地在我的Android設備上收到了測試推送消息。城市飛艇推碼
現在我想要做的下一件事就是使用JAVA定位我的設備併發送推送消息。 從我目前看到的最好的方式來實現這一點是使用他們的Web API。
但是當我試圖發送一個消息後,我總是得到以下錯誤:
產生java.io.IOException:服務器返回的HTTP響應代碼:401網址:https://go.urbanairship.com/api/push/ 在sun.net .www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(Unknown Source) at com.Sender.Sender.main(Sender.java:56)
這是我使用的代碼:
package com.Sender;
import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.Authenticator;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
public class Sender {
/**
* @param args
*/
public static void main(String[] args) {
try {
String responseString = "";
String outputString = "";
String username = "MWMoRVhmRXOG6IrvhMm-BA";
String password = "ebsJS2iXR5aMJcOKe4rCcA";
MyAuthenticator ma= new MyAuthenticator(username, password);
Authenticator.setDefault(ma);
URL url = new URL("https://go.urbanairship.com/api/push/");
URLConnection urlConnection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection) urlConnection;
ByteArrayOutputStream bout = new ByteArrayOutputStream();
String APID = "23eef280-19c8-40fc-b798-788f50e255a2";
String postdata = "{\"android\": {\"alert\": \"Hello from JAVA!\"}, \"apids\": [\""+APID+"\"]}";
byte[] buffer = new byte[postdata.length()];
buffer = postdata.getBytes("UTF8");
bout.write(buffer);
byte[] b = bout.toByteArray();
httpConn.setRequestProperty("Content-Length",
String.valueOf(b.length));
httpConn.setRequestProperty("Content-Type", "application/json");
httpConn.setRequestMethod("POST");
httpConn.setDoOutput(true);
httpConn.setDoInput(true);
OutputStream out = httpConn.getOutputStream();
out.write(b);
out.close();
InputStreamReader isr = new InputStreamReader(
httpConn.getInputStream());
BufferedReader in = new BufferedReader(isr);
while ((responseString = in.readLine()) != null) {
outputString = outputString + responseString;
}
System.out.println(outputString);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
你能幫助我嗎?
謝謝你的回覆。但是「Authenticator.setDefault(ma)」這行代碼如何呢? 。我認爲這需要處理所有事情。否則,我應該如何將Authenticator作爲標題的一部分? – Ivelius 2012-01-29 13:17:46
我不認爲setDefaul就夠了。在我的回答中發佈的鏈接中有如何將Authenticator設置爲標題的一部分。 – kosa 2012-01-29 15:54:16
好吧,我按照指南,現在我得到400錯誤。這是我的新代碼和錯誤說明,下面http://pastie.org/3281240 – Ivelius 2012-01-30 09:47:23
