我找到了解决方案（感谢 Nikolay 为我指明了正确的方向）。
问题有两个方面......第一，它返回了一个 Android 不喜欢的站点证书，第二，它只启用了 SSLv3（而不是 TLS）。
这是我的解决方案。首先我必须创建一个自定义套接字工厂类：
public class MySSLSocketFactory extends SSLSocketFactory {
SSLContext sslContext = SSLContext.getInstance("SSLv3");
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 {
SSLSocket S = (SSLSocket) sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
S.setEnabledProtocols(new String[] {"SSLv3"});
return S;
}
@Override
public Socket createSocket() throws IOException {
SSLSocket S = (SSLSocket) sslContext.getSocketFactory().createSocket();
S.setEnabledProtocols(new String[] {"SSLv3"});
return S;
}
}
其次，我在我的代码中定义了这个自定义的 HttpClient：
public HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
MySSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(MySSLSocketFactory.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();
}
}
第三，我调用了自定义的HttpClient并解析了结果：
public String test(String URIString) {
HttpClient httpClient = getNewHttpClient();
String result = "";
URI uri;
try {
uri = new URI(URIString);
} catch (URISyntaxException e1) {
return "ERROR";
}
HttpHost host = new HttpHost(uri.getHost(), 443, uri.getScheme());
HttpPost httppost = new HttpPost(uri.getPath());
try {
HttpResponse response = httpClient.execute(host, httppost);
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent()
)
);
String line = null;
while ((line = reader.readLine()) != null){
result += line + "\n";
}
return result;
} catch (ClientProtocolException e) {
return "ERROR";
} catch (IOException e) {
return "ERROR";
}
}
