Android HTTPS请求总结

HttpClient

KeyStore keyStore;
URI url = null;
HttpGet req = null;

try{//获取asset文件夹下的证书AssetManager am = mContext.getAssets();InputStream ins = am.open("my.crt"); //证书格式转换 IE 工具->internet->内容->证书

   try {//读取证书

      CertificateFactory cerFactory = CertificateFactory.getInstance("X.509");  //证书工厂。此处指明证书的类型 

     Certificate cer = cerFactory.generateCertificate(ins);//创建一个证书库，并将证书导入证书库

      keyStore = KeyStore.getInstance("PKCS12", "BC");   //问2  http://www.csdn.net/article/2015-01-06/2823434keyStore.load(null, null);keyStore.setCertificateEntry("trust", cer);} finally {ins.close();}//把咱的证书库作为信任证书库

   SSLSocketFactory socketFactory = new SSLSocketFactory(keyStore);Scheme sch = new Scheme("https", socketFactory, 443);//完工

   HttpClient mHttpClient = new DefaultHttpClient();mHttpClient.getConnectionManager().getSchemeRegistry().register(sch);url = new URI(gm.url+gm.param);//url = new URI(gm.url+gm.param);
   req = new HttpGet(url);HttpGet requestGet = new HttpGet(url);HttpResponse httpResponse = mHttpClient.execute(requestGet);if (httpResponse.getStatusLine().getStatusCode() == 200) {HttpEntity httpEntity = httpResponse.getEntity();result = EntityUtils.toString(httpEntity);result = result.replaceAll("\r", "");}
}catch (Exception e){}

HttpsURLConnection

CertificateFactory cf = CertificateFactory.getInstance("X.509");
// From
// https://www.washington.edu/itconnect/security/ca/load-der.crt
InputStream caInput = mContext.getAssets().open("_.lianluo.com_bundle.crt");
//InputStream caInput = mContext.getAssets().open("nginx.crt");

Certificate ca;
try {ca = cf.generateCertificate(caInput);
} finally {caInput.close();
}// Create a KeyStore containing our trusted CAs
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);// Create a TrustManager that trusts the CAs in our KeyStore
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);// Create an SSLContext that uses our TrustManager
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);URL url = new URL(path);
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
//
urlConnection.setConnectTimeout(5 * 1000);
urlConnection.setRequestMethod("GET");
//
urlConnection.setSSLSocketFactory(context.getSocketFactory());InputStream in = urlConnection.getInputStream();if(urlConnection.getResponseCode() == HttpURLConnection.HTTP_OK){return readStream(in);
}
