我想从我自己的托管服务器（使用自签名证书保护）下载文件。服务器本身需要根据请求验证客户端。现在，我想使用Android客户端中的下载管理器从服务器下载文件，但是似乎无法使用DownloadManager验证我的Android客户端。
如果我仅使用下载管理器坚持下载文件该怎么办，有什么方法可以自定义下载管理器类以进行身份验证以及信任服务器？
注意：使用自定义HttpClient调用，Api调用已经可以使用。
HttpCall代码：
public int HttpsCall()
{
int version=0;
if(Build.VERSION.SDK_INT>9)
{
StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpGet httpGet = new HttpGet("https://someurl/CheckVersionApi.php");
try {
HttpResponse response=null;
response= client.execute(httpGet);
if(response!=null)
{
Toast.makeText(this, "Null nahi h", Toast.LENGTH_SHORT).show();
}
HttpEntity httpEntity = response.getEntity();
InputStream is = httpEntity.getContent();
BufferedReader read = new BufferedReader(new InputStreamReader(is));
String query = null;
while ((query = read.readLine()) != null) {
Log.d("Responce ", "" + query);
Toast.makeText(this, ""+query, Toast.LENGTH_SHORT).show();
version= Integer.valueOf(query);
}
Log.d("Responce", String.valueOf(response.getStatusLine().getStatusCode()));
} catch (IOException e) {
e.printStackTrace();
}
return version;
}
HTTP CLASS：
public class MyHttpClient extends DefaultHttpClient {
final Context context;
public MyHttpClient(Context context) {
this.context = context;
}
@Override
protected ClientConnectionManager createClientConnectionManager() {
SchemeRegistry registry = new SchemeRegistry();
Toast.makeText(context, "CreateClient", Toast.LENGTH_SHORT).show();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
// Register for port 443 our SSLSocketFactory with our keystore to the ConnectionManager
registry.register(new Scheme("https", newSslSocketFactory(), 443));
return new SingleClientConnManager(getParams(), registry);
}
private SSLSocketFactory newSslSocketFactory() {
try {
// Get an instance of the Bouncy Castle KeyStore format
KeyStore trusted = KeyStore.getInstance("BKS");
Toast.makeText(context, "Keystore", Toast.LENGTH_SHORT).show();
// Get the raw resource, which contains the keystore with your trusted certificates (root and any intermediate certs)
File file=new File("storage/emulated/0","clienttruststore.bks/");
FileInputStream in =new FileInputStream(file);
//context.getResources().openRawResource(R.raw.clienttruststore);
KeyStore keystore = KeyStore.getInstance("BKS");
Toast.makeText(context, "Keystore", Toast.LENGTH_SHORT).show();
File file1=new File("storage/emulated/0","client.bks/");
FileInputStream in1 =new FileInputStream(file1);
// / Get the raw resource, which contains the keystore with your trusted certificates (root and any intermediate certs)
// InputStream in1 = context.getResources().openRawResource(R.raw.client);
try {
// Initialize the keystore with the provided trusted certificates.
// Also provide the password of the keystore
trusted.load(in, "qazwsx@123".toCharArray());
keystore.load(in1, "qazwsx@123".toCharArray());
} finally {
in.close();
}
// Pass the keystore to the SSLSocketFactory. The factory is responsible for the verification of the server certificate.
// SSLSocketFactory sf = new SSLSocketFactory(trusted);
SSLSocketFactory sf = new SSLSocketFactory(SSLSocketFactory.TLS, keystore, "qazwsx@123",
trusted, null, null);
// Hostname verification from certificate
// http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d4e506
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Toast.makeText(context, "KeystoreEnd", Toast.LENGTH_SHORT).show();
return sf;
} catch (Exception e) {
throw new AssertionError(e);
}
