android中進行https連接方法
如果是忽略憑證的做法
public class Demo extends Activity {
/** Called when the activity is first created. */
private TextView text;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
text = (TextView)findViewById(R.id.text);
GetHttps();
}
private void GetHttps(){
String https = " https://800wen.com/";
try{
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, new TrustManager[]{new MyTrustManager()}, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(new MyHostnameVerifier());
HttpsURLConnection conn = (HttpsURLConnection)new URL(https).openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuffer sb = new StringBuffer();
String line;
while ((line = br.readLine()) != null)
sb.append(line);
text.setText(sb.toString());
}catch(Exception e){
Log.e(this.getClass().getName(), e.getMessage());
}
}
private class MyHostnameVerifier implements HostnameVerifier{
@Override
public boolean verify(String hostname, SSLSession session) {
// TODO Auto-generated method stub
return true;
}
}
private class MyTrustManager implements X509TrustManager{
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
// TODO Auto-generated method stub
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
// TODO Auto-generated method stub
}
@Override
public X509Certificate[] getAcceptedIssuers() {
// TODO Auto-generated method stub
return null;
}
}
}
需要驗證憑證
AssetManager am = context.getAssets();
InputStream ins = am.open("robusoft.cer");
try {
//讀取證書
CertificateFactory cerFactory = CertificateFactory.getInstance("X.509"); //問題1
Certificate cer = cerFactory.generateCertificate(ins);
//創建一個證書庫，並將證書導入證書庫
KeyStore keyStore = KeyStore.getInstance("PKCS12", "BC"); //問題2
keyStore.load(null, null);
keyStore.setCertificateEntry("trust", cer);
return keyStore;
} finally {
ins.close();
}
//把證書庫作為信任的證書庫
SSLSocketFactory socketFactory = new SSLSocketFactory(keystore);
Scheme sch = new Scheme("https", socketFactory, 443);
//完工
HttpClient mHttpClient = new DefaultHttpClient();
mHttpClient.getConnectionManager().getSchemeRegistry().register(sch);
问1：这里用"PKCS12"不行 答1：PKCS12和JKS是keystore的type，不是Certificate的type，所以X.509不能用PKCS12代替
问2：这里用"JKS"不行。
答2：android平台上支持的keystore type好像只有PKCS12，不支持JKS，所以不能用JKS代替在PKCS12，不过在windows平台上是可以代替的
