android - HTTPS 和自签名证书问题

我必须使用 HTTPS 向服务器发送 POST 请求(使用自签名证书)。我是这样做的:

HttpClient httpClient = getHttpClient();

for (int i = 0; i < PARAMS.length && !mHttpPost.isAborted(); ++i) {
mHttpPost.setURI(URI.create(mUri + "/" + PARAMS[i].getPath()));
mHttpPost.setEntity(new UrlEncodedFormEntity(PARAMS[i].getContents(), HTTP.UTF_8));
HttpResponse response = httpClient.execute(mHttpPost);
[...]
}

getHttpClient() 定义如下:

public static DefaultHttpClient getHttpClient() {

DefaultHttpClient client = null;

// Setting up parameters
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "utf-8");
params.setBooleanParameter("http.protocol.expect-continue", false);

// Setting timeout
HttpConnectionParams.setConnectionTimeout(params, TIMEOUT);
HttpConnectionParams.setSoTimeout(params, TIMEOUT);

// Registering schemes for both HTTP and HTTPS
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
final SSLSocketFactory sslSocketFactory = SSLSocketFactory.getSocketFactory();
sslSocketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
registry.register(new Scheme("https", sslSocketFactory, 443));

// Creating thread safe client connection manager
ThreadSafeClientConnManager manager = new ThreadSafeClientConnManager(params, registry);

// Creating HTTP client
client = new DefaultHttpClient(manager, params);

return client;

}

但我收到“不可信服务器证书”异常。我知道这里已经发布了几个关于自签名证书的问题,但没有一个对我有用...

有人知道怎么做吗?

一些细节:我在模拟器上使用 API 级别 4 (Android 1.6)。

最佳答案

我终于解决了它,使用 SSLSocketFactory 的自定义子类:

public class CustomSSLSocketFactory extends SSLSocketFactory {

private SSLContext sslContext = SSLContext.getInstance("TLS");

public CustomSSLSocketFactory(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();
}

}

我按如下方式使用它:

public HttpClient getHttpClient() {

DefaultHttpClient client = null;

try {

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);

SSLSocketFactory sf = new CustomSSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

// Setting up parameters
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "utf-8");
params.setBooleanParameter("http.protocol.expect-continue", false);

// Setting timeout
HttpConnectionParams.setConnectionTimeout(params, TIMEOUT);
HttpConnectionParams.setSoTimeout(params, TIMEOUT);

// Registering schemes for both HTTP and HTTPS
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));

// Creating thread safe client connection manager
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

// Creating HTTP client
client = new DefaultHttpClient(ccm, params);

// Registering user name and password for authentication
client.getCredentialsProvider().setCredentials(
new AuthScope(null, -1),
new UsernamePasswordCredentials(mUsername, mPassword));

} catch (Exception e) {
client = new DefaultHttpClient();
}

return client;

}

不知道为什么我找到的其他解决方案对我不起作用...
