更改HTTP POST请求HTTPS POST请求：

Question

我有这样的方法：

public static String getReportMetadata (String reportId, String sessionId, String url) throws Exception{ 

    Map<String, Object> jsonValues = new HashMap<String, Object>(); 
    jsonValues.put("reportID", reportId); 
    jsonValues.put("sessionID", sessionId); 
    JSONObject json = new JSONObject(jsonValues); 

    DefaultHttpClient client = new DefaultHttpClient(); 

    HttpPost post = new HttpPost(url + GET_REPORT_METADATA_ACTION); 

    AbstractHttpEntity entity = new ByteArrayEntity(json.toString().getBytes("UTF8")); 
    entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); 
    post.setEntity(entity);   
    HttpResponse response = client.execute(post); 

    return getContent(response);    
} 

执行，其中，当然我跑使用AsyncTask到从服务器获取数据的HTTP发布采购信息。

我的问题： 可能有人请用简单的方法是什么我需要执行这个连接类型更改为安全连接（a.k.a使用HTTPS）的步骤，向我解释。 只能从android的角度来看（意思是客户端应用程序）。

更新： 正如建议我试图改变只有链接并添加https而不是http，但它不会返回一个答案。据我了解我需要获得并储存一个自签证书，才能连接到服务器端

UPDATE2： 为我的作品的解决方案：

EasySSLSocketFactory：

public class EasySSLSocketFactory implements SocketFactory, LayeredSocketFactory { 

private SSLContext sslcontext = null; 

private static SSLContext createEasySSLContext() throws IOException { 
    try { 
     SSLContext context = SSLContext.getInstance("TLS"); 
     context.init(null, new TrustManager[] { new EasyX509TrustManager(null) }, null); 
     return context; 
    } catch (Exception e) { 
     throw new IOException(e.getMessage()); 
    } 
} 

private SSLContext getSSLContext() throws IOException { 
    if (this.sslcontext == null) { 
     this.sslcontext = createEasySSLContext(); 
    } 
    return this.sslcontext; 
} 

/** 
* @see org.apache.http.conn.scheme.SocketFactory#connectSocket(java.net.Socket, java.lang.String, int, 
*  java.net.InetAddress, int, org.apache.http.params.HttpParams) 
*/ 
public Socket connectSocket(Socket sock, String host, int port, InetAddress localAddress, int localPort, 
     HttpParams params) throws IOException, UnknownHostException, ConnectTimeoutException { 
    int connTimeout = HttpConnectionParams.getConnectionTimeout(params); 
    int soTimeout = HttpConnectionParams.getSoTimeout(params); 
    InetSocketAddress remoteAddress = new InetSocketAddress(host, port); 
    SSLSocket sslsock = (SSLSocket) ((sock != null) ? sock : createSocket()); 

    if ((localAddress != null) || (localPort > 0)) { 
     // we need to bind explicitly 
     if (localPort < 0) { 
      localPort = 0; // indicates "any" 
     } 
     InetSocketAddress isa = new InetSocketAddress(localAddress, localPort); 
     sslsock.bind(isa); 
    } 

    sslsock.connect(remoteAddress, connTimeout); 
    sslsock.setSoTimeout(soTimeout); 
    return sslsock; 

} 

/** 
* @see org.apache.http.conn.scheme.SocketFactory#createSocket() 
*/ 
public Socket createSocket() throws IOException { 
    return getSSLContext().getSocketFactory().createSocket(); 
} 

/** 
* @see org.apache.http.conn.scheme.SocketFactory#isSecure(java.net.Socket) 
*/ 
public boolean isSecure(Socket socket) throws IllegalArgumentException { 
    return true; 
} 

/** 
* @see org.apache.http.conn.scheme.LayeredSocketFactory#createSocket(java.net.Socket, java.lang.String, int, 
*  boolean) 
*/ 
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, 
     UnknownHostException { 
    return getSSLContext().getSocketFactory().createSocket(socket, host, port, autoClose); 
} 

// ------------------------------------------------------------------- 
// javadoc in org.apache.http.conn.scheme.SocketFactory says : 
// Both Object.equals() and Object.hashCode() must be overridden 
// for the correct operation of some connection managers 
// ------------------------------------------------------------------- 

public boolean equals(Object obj) { 
    return ((obj != null) && obj.getClass().equals(EasySSLSocketFactory.class)); 
} 

public int hashCode() { 
    return EasySSLSocketFactory.class.hashCode(); 
} 
} 

EasyX509TrustManager：

public class EasyX509TrustManager implements X509TrustManager { 

private X509TrustManager standardTrustManager = null; 

/** 
* Constructor for EasyX509TrustManager. 
*/ 
public EasyX509TrustManager(KeyStore keystore) throws NoSuchAlgorithmException, KeyStoreException { 
    super(); 
    TrustManagerFactory factory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm()); 
    factory.init(keystore); 
    TrustManager[] trustmanagers = factory.getTrustManagers(); 
    if (trustmanagers.length == 0) { 
     throw new NoSuchAlgorithmException("no trust manager found"); 
    } 
    this.standardTrustManager = (X509TrustManager) trustmanagers[0]; 
} 

/** 
* @see javax.net.ssl.X509TrustManager#checkClientTrusted(X509Certificate[],String authType) 
*/ 
public void checkClientTrusted(X509Certificate[] certificates, String authType) throws CertificateException { 
    standardTrustManager.checkClientTrusted(certificates, authType); 
} 

/** 
* @see javax.net.ssl.X509TrustManager#checkServerTrusted(X509Certificate[],String authType) 
*/ 
public void checkServerTrusted(X509Certificate[] certificates, String authType) throws CertificateException { 
    if ((certificates != null) && (certificates.length == 1)) { 
     certificates[0].checkValidity(); 
    } else { 
     standardTrustManager.checkServerTrusted(certificates, authType); 
    } 
} 

/** 
* @see javax.net.ssl.X509TrustManager#getAcceptedIssuers() 
*/ 
public X509Certificate[] getAcceptedIssuers() { 
    return this.standardTrustManager.getAcceptedIssuers(); 
} 
} 

我加入这个方法：getNewHttpClient（）

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) { 
     return new DefaultHttpClient(); 
    } 
} 

最后在我的代码，每一个地方，我有：

HttpClient client = getNewHttpClient(); 

：

DefaultHttpClient client = new DefaultHttpClient(); 

我代之以

我现在可以从服务器端接收数据，最后一个问题是：我做的是安全的吗？或者它接受每个自签名证书？如果是这种情况，应该做些什么来改变它？

任何帮助，将不胜感激。

Answer 1

来自Apache HttpClient SSL guide：

通过SSL的安全HTTP通信应该与普通HTTP通信一样简单。

所以，你应该简单地将HTTP改变：// XXXX到HTTPS：// XXXX

编辑：我刚看到@Barend的答案是更完整的

Answer 2

首先你需要创建SchemeRegistry对象并使用注册新方案的SSLSocketFactory的：

SchemeRegistry schemeRegistry = new SchemeRegistry(); 
schemeRegistry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443)); 

然后你就可以使用SchemeRegistry对象创建SingleClientConnManager：

SingleClientConnManager mgr = new SingleClientConnManager(schemeRegistry); 

最后您创建DefaultHttpClient使用SingleClientConnManager：

HttpClient client = new DefaultHttpClient(mgr);
