本文介绍了一种绕过HTTPS验证的方法，解决了Android热更新时无法连接服务器的问题。通过对cocos2dx的源码进行修改，创建了一个自定义的SSLSocketFactory类，并在Cocos2dxDownloader的createDownloader方法中替换了默认的安全套接字工厂。

最近苹果宣布所有上架应用都要用https,我们后端走的是同一个函数,导致Android也要连接https.

百度了下,网上说客户端不需要做什么特殊处理,因为cocos本身是支持https的.但是服务端自建的证书是不行的.需要购买的证书才可以.

但是还有个问题,购买的证书,Android可以拿到服务器列表,但是热更新时连不上热更新的服务器.

下面是我的解决方法.(思路是绕过https验证,借鉴了网上的代码)

找到这个jar文件,这个是热更新时连接服务器的java文件编译后的文件.具体的路径在

cocos2d-x-3.13.1\cocos\platform\android\java\src\org\cocos2dx\lib

找到扩展名为.java的文件才能编辑,否则是编辑不了.

下面是我修改的代码部分.

//內建类,下面会用到
public class SSLSocketFactor extends SSLSocketFactory {

        SSLContext sslContext = SSLContext.getInstance("TLS");
        
        public SSLSocketFactor(KeyStore truststore)
                throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
            super(truststore);
            // TODO Auto-generated constructor stub
            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); 
        }
    }

//修改cocos2dx原有的方法
public static Cocos2dxDownloader createDownloader(int id, int timeoutInSeconds, String tempFileNameSufix, int countOfMaxProcessingTasks) {
        Cocos2dxDownloader downloader = new Cocos2dxDownloader();
        downloader._id = id;

        downloader._httpClient.setEnableRedirects(true);
        if (timeoutInSeconds > 0) {
            downloader._httpClient.setTimeout(timeoutInSeconds * 1000);
        }
        
        try {  
            //Secure Protocol implementation.    
            SSLContext ctx = SSLContext.getInstance("SSL");  
            //Implementation of a trust manager for X509 certificates    
            X509TrustManager tm = new X509TrustManager() {  
  
                public void checkClientTrusted(X509Certificate[] xcs,  
                        String string) throws CertificateException {  
  
                }  
  
                public void checkServerTrusted(X509Certificate[] xcs,  
                        String string) throws CertificateException {  
                }  
  
                public X509Certificate[] getAcceptedIssuers() {  
                    return null;  
                }  
            };  
            ctx.init(null, new TrustManager[] { tm }, null);  
            SSLSocketFactory ssf = new SSLSocketFactory(ctx);

//允许所有的验证通过            
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
            downloader._httpClient.setSSLSocketFactory(ssf);
        } catch (Exception e) {  
            e.printStackTrace();  
        }    
        
        // downloader._httpClient.setMaxRetriesAndTimeout(3, timeoutInSeconds * 1000);
        downloader._httpClient.allowRetryExceptionClass(javax.net.ssl.SSLException.class);
        downloader._tempFileNameSufix = tempFileNameSufix;
        downloader._countOfMaxProcessingTasks = countOfMaxProcessingTasks;
        return downloader;
    }
