A. jpush推送java後台怎麼調用
開發的時候需要引用appache的包commons-httpclient.jar 、commons-codec.jar、commons-logging.jar這些包可以到官網上下載，如果有需要的話也我也可以發給你。
引入上述這些包之後，就可以進行開發了。
這里需要特別說明的兩點是：
1、通過 HttpClient client = new DefaultHttpClient(); 獲得HttpClient對象不支持https，需要自己重寫。
2、我們的MD5編碼要和伺服器那邊的一樣。（我用我自己寫的MD5編碼驗證的時候，總是驗證失敗，後來跟他們的技術人員要了他們的md5的實現方式就通過驗證了）
好了，廢話不多說了，接下來是貼代碼的時候了：
類MySSLSocketFactory用來實現對https的支持
[java] view plain
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ssl.SSLSocketFactory;
public class MySSLSocketFactory extends SSLSocketFactory {
SSLContext sslContext = SSLContext.getInstance("TLS");
public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
super(truststore);
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
sslContext.init(null, new TrustManager[] { tm }, null);
}
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return sslContext.getSocketFactory().createSocket();
}
}
類ClientUtil 獲取可以支持https的HttpClient對象，調用MySSLSocketFactory 來取得
[java] view plain
import java.security.KeyStore;
import org.apache.http.HttpVersion;
import org.apache.http.client.HttpClient;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.PlainSocketFactory;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpParams;
import org.apache.http.params.HttpProtocolParams;
import org.apache.http.protocol.HTTP;
public class ClientUtil {
public static HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
e.printStackTrace();
return new DefaultHttpClient();
}
}
}
接下來就是調用JPush的api來推送消息了
[java] view plain
import java.util.ArrayList;
import java.util.List;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
/**

public static void pushMsg(String msg) {
BasicNameValuePair name = new BasicNameValuePair("username", "test"); //用戶名

BasicNameValuePair appkeys = new BasicNameValuePair("appkeys", "your appkeys"); // 待發送的應用程序(appKey)，只能填一個。
BasicNameValuePair receiver_type = new BasicNameValuePair("receiver_type", "4");
//驗證串，用於校驗發送的合法性。
BasicNameValuePair verification_code = new BasicNameValuePair("verification_code", getVerificationCode());
//發送消息的類型：1 通知 2 自定義
BasicNameValuePair msg_type = new BasicNameValuePair("msg_type", "1");
BasicNameValuePair msg_content = new BasicNameValuePair("msg_content", msg);
//目標用戶終端手機的平台類型，如： android, ios 多個請使用逗號分隔。

List<BasicNameValuePair> datas = new ArrayList<BasicNameValuePair>();
datas.add(name);
datas.add(sendno);
datas.add(appkeys);
datas.add(receiver_type);

HttpResponse reponse = client.execute(post);
HttpEntity resEntity = reponse.getEntity();
System.out.println(EntityUtils.toString(resEntity));
} catch (Exception ex) {
ex.printStackTrace();
}
}
private static String getVerificationCode() {
String username = "test"; //username 是開發者Portal帳戶的登錄帳戶名
String password = "pasword";

}
public static void main(String[] args) {
String msg = "{\"n_title\":\"來點外賣\",\"n_content\":\"你好\"}";
System.out.println(msg);
PushMsgUtil.pushMsg(msg);
}
}
