Question

我想使用HTTPS post方法将一些数据从我的Android应用程序发送到我的网站。

我首先使用了HttpURLConnection，并且我的HTTP网址正常运行。我的生产网站使用HTTPS，我想使用HttpsURLConnection发送相同的POST。有人可以帮我正确使用课程吗？

我在this link找到了一些来源：

KeyStore keyStore = ...;    
TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");    
tmf.init(keyStore);

SSLContext context = SSLContext.getInstance("TLS");   
context.init(null, tmf.getTrustManagers(), null);

URL url = new URL("https://www.example.com/");   
HttpsURLConnection urlConnection = (HttpsURLConnection)
url.openConnection();   
urlConnection.setSSLSocketFactory(context.getSocketFactory());   
InputStream in = urlConnection.getInputStream();

KeyStore keyStore = ...;的价值应该是什么？

我尝试使用相同的HttpURLConnection发送数据，但我看到一些POST数据丢失或出错。

我尝试过this question的方法。我正在粘贴下面的代码

String urlParameters="dateTime=" + URLEncoder.encode(dateTime,"UTF-8")+
    "&mobileNum="+URLEncoder.encode(mobileNum,"UTF-8");

URL url = new URL(myurl);
HttpsURLConnection conn;
conn=(HttpsURLConnection)url.openConnection();

// Create the SSL connection
SSLContext sc;
sc = SSLContext.getInstance("TLS");
sc.init(null, null, new java.security.SecureRandom());
conn.setSSLSocketFactory(sc.getSocketFactory());
conn.setConnectTimeout(HTTP_CONNECT_TIME_OUT);
conn.setReadTimeout(HTTP_READ_TIME_OUT);

//set the output to true, indicating you are outputting(uploading) POST data
conn.setDoOutput(true);
//once you set the output to true, you don't really need to set the request method to post, but I'm doing it anyway
conn.setRequestMethod("POST");
conn.setFixedLengthStreamingMode(urlParameters.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(urlParameters);
out.close();

InputStream is = conn.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String inputLine;
while ((inputLine = in.readLine()) != null) {
  response += inputLine;            
}

我得到的错误如下：

Answer 1

您可以使用Android设备中定义的默认CA，这对任何公共网络都适用。

如果您有自签名证书，您可以接受所有证书（有风险，对中间人攻击开放）或创建自己的TrustManagerFactory，这有点超出此范围

以下是使用默认CA进行https POST调用的一些代码：

private InputStream getInputStream(String urlStr, String user, String password) throws IOException
{
    URL url = new URL(urlStr);
    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

    // Create the SSL connection
    SSLContext sc;
    sc = SSLContext.getInstance("TLS");
    sc.init(null, null, new java.security.SecureRandom());
    conn.setSSLSocketFactory(sc.getSocketFactory());

    // Use this if you need SSL authentication
    String userpass = user + ":" + password;
    String basicAuth = "Basic " + Base64.encodeToString(userpass.getBytes(), Base64.DEFAULT);
    conn.setRequestProperty("Authorization", basicAuth);

    // set Timeout and method
    conn.setReadTimeout(7000);
    conn.setConnectTimeout(7000);
    conn.setRequestMethod("POST");
    conn.setDoInput(true);

    // Add any data you wish to post here

    conn.connect();
    return conn.getInputStream();
}

阅读回复：

        String result = new String();
        InputStream is = getInputStream(urlStr, user, password);
        BufferedReader in = new BufferedReader(new InputStreamReader(is));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            result += inputLine;            
        }

Answer 2

你可以看看我几天前提出的这个问题：

Change HTTP post request to HTTPS post request:

我提供了一个适合我的解决方案，它基本上接受任何自签名证书。正如在这里所说的那样，不推荐这种解决方案，因为它不安全，并且对中间人攻击持开放态度。

以下是代码：

<强> 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();
}
}

<强> 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();
}
}

我添加了这个方法：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，我的代码中的每个地方都有：

DefaultHttpClient client = new DefaultHttpClient();

我将其替换为：

HttpClient client = getNewHttpClient();

这是Android HttpsUrlConnection POST solution完成的证书固定，超时服务器端代码和配置。

变量params的格式应为username = demo＆amp; password = abc123＆amp;。

@Override
public String sendHttpRequest(String params) {
    String result = "";
    try {
        URL url = new URL(AUTHENTICATION_SERVER_ADDRESS);
        HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
        connection.setSSLSocketFactory(KeyPinStore.getInstance().getContext().getSocketFactory()); // Tell the URLConnection to use a SocketFactory from our SSLContext
        connection.setRequestMethod("POST");
        connection.setDoOutput(true);
        connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        connection.setConnectTimeout(10000);
        connection.setReadTimeout(10000);
        PrintWriter out = new PrintWriter(connection.getOutputStream());
        out.println(params);
        out.close();
        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()), 8192);
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            result = result.concat(inputLine);
        }
        in.close();
        //} catch (IOException e) {
    } catch (IOException | KeyStoreException | CertificateException | KeyManagementException | NoSuchAlgorithmException e) {
        result = e.toString();
        e.printStackTrace();
    }
    return result;
}
