隨著互聯(lián)網(wǎng)的發(fā)展,各種編程語言也相繼誕生,其中PHP和Java是非常熱門的兩種語言,如何將它們進行組合使用呢?
對于PHP和Java的結(jié)合,可以通過Java和PHP之間的Web服務來實現(xiàn)。具體來說,可以通過Java編寫一些WebService,然后PHP發(fā)起請求并調(diào)用WebService,來實現(xiàn)Java和PHP之間的相互調(diào)用。比如,在Java中實現(xiàn)一個WebService,用于返回當前時間。代碼如下:
import java.util.Date; import javax.jws.WebService; @WebService public class TimeService { public String getTime(){ return new Date().toString(); } }
然后,在PHP中調(diào)用這個WebService,代碼如下:
$client = new SoapClient('http://localhost:8080/helloworld?wsdl'); $result = $client->__soapCall('getTime',array()); echo $result; //輸出結(jié)果:2017-09-05 16:57:00
與此類似的,PHP也可以通過WebService向Java發(fā)送請求,從而實現(xiàn)調(diào)用Java中的一些功能,如發(fā)送郵件等。比如,Java中實現(xiàn)一個發(fā)送郵件的WebService,代碼如下:
import javax.jws.WebMethod; import javax.jws.WebService; import javax.mail.*; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; @WebService public class EmailService { @WebMethod public boolean sendEmail(String username, String password, String toAddress, String title, String content) { try { Properties props = new Properties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.host", "smtp.163.com"); Session session = Session.getInstance(props, new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }); Message message = new MimeMessage(session); message.setFrom(new InternetAddress(username)); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toAddress)); message.setSubject(title); message.setText(content); Transport.send(message); return true; } catch (Exception e) { e.printStackTrace(); return false; } } }
然后,在PHP中調(diào)用這個WebService,代碼如下:
$client = new SoapClient('http://localhost:8080/EmailService?wsdl'); $result = $client->__soapCall('sendEmail',array('username'=>'xxx@163.com', 'password'=>'password', 'toAddress'=>'xxx@xxx.com', 'title'=>'test', 'content'=>'test')); if($result) { echo 'send success'; } else { echo 'send fail'; }
通過以上示例可見,PHP和Java的組合可以很好地發(fā)揮各自的優(yōu)勢,實現(xiàn)更加豐富的功能,具有很強的靈活性和擴展性。
