Question

我有一个Java应用程序（服务器控制器），我需要与PHP来回通信，我想知道最好的方法吗？

我最初的想法是使用XML并让PHP和Java两端通过HTTP相互发送XML消息，但这种方法似乎非常复杂。有没有人知道任何其他方法或任何方式这样做？ Tomcat会是个好主意吗？那么PHP/Java Bridge呢？

Answer 1

如果它是基于Web的Java应用程序，我将实现一个简单的REST API，然后在php中使用CURL。

Answer 2

你可以使用soap来使用标准XML，我认为你需要一个像tomcat或jboss这样的应用服务器，并在java端定义一些服务。

PHP附带SoapClient类，可以扩展以简化接口的实现

**Step1.** Create php file and put it inside www folder if you are using wamp server(Enable SSL on wamp if you want to communicate on SSL).

**phpFile.php**


<?PHP
// connect via SSL, but don't check cert
$url=curl_init('https://www.google.co.in/?gws_rd=ssl');
curl_setopt($url, CURLOPT_POST, 1);
curl_setopt($url, CURLOPT_CUSTOMREQUEST, 'POST'); //without this line the request is being sent with GET method (I can see that with curl_getinfo)
curl_setopt($url, CURLOPT_PORT, 443);
curl_setopt($url, CURLOPT_VERBOSE, true);
curl_setopt($url, CURLOPT_RETURNTRANSFER, true);
curl_setopt($url, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($url, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded;")); 
curl_setopt($url, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36 Fiddler');
curl_setopt($url, CURLOPT_POST, 1);
$content = curl_exec($url);
if(curl_error($url))
{
echo "Error: >> ".curl_error($url);
exit;
}
echo $content; // show target page
?>



**Step2. Create java file like**



package com.ravisoft.test;

import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import java.security.cert.X509Certificate;


public class PHPCurlSSL {
  public static void main(String[] args) throws Exception {
      DataOutputStream outStream;
    /*
     *  fix for
     *    Exception in thread "main" javax.net.ssl.SSLHandshakeException:
     *       sun.security.validator.ValidatorException:
     *           PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException:
     *               unable to find valid certification path to requested target
     */
    TrustManager[] trustAllCerts = new TrustManager[] {
       new X509TrustManager() {
          public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
          }

          public void checkClientTrusted(X509Certificate[] certs, String authType) {  }

          public void checkServerTrusted(X509Certificate[] certs, String authType) {  }

       }
    };

    //String body = "reqUrl=" + URLEncoder.encode("https:// your URL", "UTF-8");

    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

    // Create all-trusting host name verifier
    HostnameVerifier allHostsValid = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
          return true;
        }
    };
    // Install the all-trusting host verifier
    HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
    /*
     * end of the fix
     */

    URL url = new URL("https://localhost/phpFile.php");

    URLConnection con = url.openConnection();
    ((HttpURLConnection)con).setRequestMethod("POST");
    con.setDoInput(true);
    con.setDoOutput(true);
    con.setUseCaches(false);
    con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    //con.setRequestProperty("Content-Length", ""+ body.length());
    //outStream = new DataOutputStream(con.getOutputStream());
 // Send request
    //outStream.writeBytes(body);
    //outStream.flush();
    //outStream.close();
    Reader reader = new InputStreamReader(con.getInputStream());
    while (true) {
      int ch = reader.read();
      if (ch==-1) {
        break;
      }
      System.out.print((char)ch);
    }
  }
}




**Step 3. Some other steps like.**
 a. You may need to change your port
 b. You may need to create ssl certificate
 c. change php.ini in apache and php in  wamp to enable curl and ssl.
 d. You can send arguments from java to php

PHP和Java之间的通信
