Question

这是我的HTTP JSON

 {  
 "User": {    
    "Name": "Compulsary","Password": "Compulsary"  }
}

我必须使用HTTPS POST请求发布到服务器。当我尝试发送请求时，我收到SSL服务器证书异常。我该如何解决这个问题？

我尝试了什么？

我尝试将HTTPPost与HTTPClient一起使用。 SSL异常。我也尝试使用URLConnection并忽略了SSL证书的检查。我收到401和405响应代码。

问题陈述：

将上述POST请求发送到服务器（请求是安全的，接受https）。如何在android中实现这一点？

我试过这个，我的代码，我得到405错误？

// always verify the host - dont check for certificate
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

/**
 * Trust every server - dont check for any certificate
 */
private static void trustAllHosts() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[] {};
        }

        public void checkClientTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }

        public void checkServerTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }
    } };

    // Install the all-trusting trust manager
    try {
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());

第1步：创建一个类MySSLSocketFactory并包含以下代码：

public class MySSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public MySSLSocketFactory(KeyStore truststore)
                    throws NoSuchAlgorithmException, KeyManagementException,
                    KeyStoreException, UnrecoverableKeyException {
            super(truststore);

            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);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port,
                    boolean autoClose) throws IOException, UnknownHostException {
            return sslContext.getSocketFactory().createSocket(socket, host, port,
                            autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
            return sslContext.getSocketFactory().createSocket();
    }

}

第2步：创建课程WebClientDevWrapper并包含以下代码：

public class WebClientDevWrapper {

    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();
         }
     }

}

第3步：在您的Activity或其他地方创建一个方法，此方法将用于进行网络通话。

/**
     * Request JSON based web service to get response
     * 
     * @param url
     *            - base URL
     * @param request
     *            - JSON request
     * @return response
     * @throws ClientProtocolException
     * @throws IOException
     * @throws IllegalStateException
     * @throws JSONException
     */
    public HttpResponse request(String url, JSONObject request)
            throws ClientProtocolException, IOException, IllegalStateException,
            JSONException {

        DefaultHttpClient client = (DefaultHttpClient) WebClientDevWrapper.getNewHttpClient();

            HttpPost post = new HttpPost(url);
            post.setEntity(new StringEntity(request.toString(), "utf-8"));
            HttpResponse response = client.execute(post);
            return response;
        }
    }

我使用以下代码进行https / http / wift / 3G的组合，希望有所帮助

public class CustomHttpClient {
private static DefaultHttpClient customHttpClient;

/** A private Constructor prevents instantiation */
private CustomHttpClient() {
}

public static synchronized DefaultHttpClient getHttpClient() {
    if (customHttpClient == null) {
        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params,
                HTTP.DEFAULT_CONTENT_CHARSET);
        HttpProtocolParams.setUseExpectContinue(params, true);
        HttpProtocolParams.setUserAgent(params, "Mozilla/5.0 (Linux; U; Android 2.2.1; en-us; Nexus One Build/FRG83) AppleWebKit/533.1(KHTML, like Gecko) Version/4.0 Mobile Safari/533.1");
        ConnManagerParams.setTimeout(params, 1000);
        HttpConnectionParams.setConnectionTimeout(params, 5000);
        HttpConnectionParams.setSoTimeout(params, 10000);
        SchemeRegistry schReg = new SchemeRegistry();
        schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
        ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params,schReg);
        customHttpClient = new DefaultHttpClient(conMgr, params);
    }
    return customHttpClient;
}

public Object clone() throws CloneNotSupportedException {
    throw new CloneNotSupportedException();
}

}

和样本

public static String Call(String URL, List<NameValuePair> postParameters)
{
    BufferedReader in = null;
    DefaultHttpClient httpClient;
    StringBuffer sb = new StringBuffer();   
    try{
        httpClient = CustomHttpClient.getHttpClient();

        HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), false); //making 3G network works*
        HttpPost request = new HttpPost(URL);
        UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters);
        request.setEntity(formEntity);
        HttpResponse response = httpClient.execute(request);
        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        String line = "";
        String NL = System.getProperty("line.separator");
        while ((line = in.readLine()) != null) {
        sb.append(line + NL);
        }
        in.close();

    }catch(Exception ex)
    {
        ex.printStackTrace();

    }
    return sb.toString();
}
