PHP与Java的通信

我有一个Java应用服务器控制器，我需要与PHP来回通信，我想知道最好的方法是什么

---

我最初的想法是使用XML，让PHP和Java端通过HTTP相互发送XML消息，但这种方法似乎相当复杂。有人知道其他的方法吗？Tomcat是个好主意吗？怎么样？

如果是基于web的Java应用程序，我会实现一个简单的REST API，然后在php中使用CURL。

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

**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

XML符合流行语，但有更好/更高效的数据交换格式，特别是在交换双方都在您的控制下的情况下。请尝试该项目。XML符合流行语，但是有更好/更高效的数据交换格式，特别是当交换双方都在您的控制下时。尝试该项目。最好的解决方案是在php中容易掌握CURL，而不是全面的soap web服务。最好的解决方案是在php中容易掌握CURL，请不要使用完整的soap web服务，请仅在代码周围使用代码块，并将解释放在代码块之外以更好地阅读答案请仅在代码周围使用代码块，并将解释放在代码块之外以更好地阅读答案
