我仅在(可能是某些)2.3.x设备上收到此错误。它适用于运行Android版本的任何其他设备。

这是我的HTTPRequestController:

public class HttpRequestController {

private final static String TAG = "HttpRequestController";

private static HttpRequestController instance;

public enum Method {
    PUT, POST, DELETE, GET
}

private HttpRequestController() {

}

public static HttpRequestController getInstance() {
    if (instance == null)
        instance = new HttpRequestController();

    return instance;
}

public String doRequest(String url, HashMap<Object, Object> data,
        Method method, String token) throws Exception {

    InputStream certificateInputStream = null;
    if (MyApplication.PRODUCTION) {
        certificateInputStream = MyApplication.context
                .getResources().openRawResource(R.raw.production_cert);
        LogUtils.log("using production SSL certificate");
    } else {
        certificateInputStream = MyApplication.context

    }

    KeyStore trustStore = KeyStore.getInstance("BKS");
    try{

    }


    TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");

    LogUtils.log("SSL: did init context with trust keyStore");  


    URL request = new URL(url);

    }
        urlConnection.setRequestMethod(method.toString());
        urlConnection.connect();

        LogUtils.log("SSL: urlConnection did connect.");

    if (method != Method.GET) {
        ObjectMapper mapper = new ObjectMapper();
        String jsonValue = mapper.writeValueAsString(data);
        OutputStream os = urlConnection.getOutputStream();
        os.write(jsonValue.getBytes());
        os.flush();
        LogUtils.log(TAG, "Params: " + jsonValue);

public HttpClient retrieveHttpClient() {
    return new MyHttpClient(MyApplication.context);

}

当我运行命令时:

openssl s_client -debug -connect www.mysitedomain.com:443

我收到回复:

所以它返回没问题......但是它仍然为我测试的2.3.x设备提供了这个错误。

在此之后我得到了一个例外:

LogUtils.log("SSL: urlConnection did set request properties.");

以下是例外:

我打电话的方式就在这里:

String response = HttpRequestController
                            .getInstance()
                            .doRequest(ApiUrls.LOGIN, params, Method.POST, null);

适用于运行2.3.x以上Android版本的任何其他设备(根据我测试的内容)。

Android文档似乎没有关于2.3兼容性的主题。

答案 0 :(得分:4)

您必须告诉Android系统信任您的证书。您的问题是2.3之后的Android接受了您的证书,因为它包含在可信证书列表中,但是之前的版本不包括在内,因此,存在问题。

我建议您在Android documentation上执行此操作:

// Load CAs from an InputStream
// (could be from a resource or ByteArrayInputStream or ...)
CertificateFactory cf = CertificateFactory.getInstance("X.509");
// From https://www.washington.edu/itconnect/security/ca/load-der.crt
InputStream caInput = new BufferedInputStream(new FileInputStream("load-der.crt"));
Certificate ca;
try {
    ca = cf.generateCertificate(caInput);
    System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());
} 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);

// Tell the URLConnection to use a SocketFactory from our SSLContext
URL url = new URL("https://certs.cac.washington.edu/CAtest/");
HttpsURLConnection urlConnection =
    (HttpsURLConnection)url.openConnection();
urlConnection.setSSLSocketFactory(context.getSocketFactory());
InputStream in = urlConnection.getInputStream();
copyInputStreamToOutputStream(in, System.out);

我也在做同样的事情,它在每台设备上运行正常,使用Android 2.3及更低版本,我的网站证书是私有的。

试试吧,告诉我它现在是否正常工作。

希望它可以帮到你!

如果有人需要答案,我终于在谷歌2天后找到了答案。基本上我们需要使用自定义TrustManager来信任KeyStore中的CA.感谢CustomTrustManager的https://github.com/delgurth

要使用它,只需获取SSLSocketFactory并应用它,例如:

使用HttpsURLConnection

KeyPinStore keystore = KeyPinStore.getInstance();
SSLSocketFactory sslSF = keystore.getContext().getSocketFactory();
URL url = new URL("https://certs.cac.washington.edu/CAtest/");
HttpsURLConnection urlConnection = (HttpsURLConnection)url.openConnection();
urlConnection.setSSLSocketFactory(sslSF);
InputStream in = urlConnection.getInputStream();
copyInputStreamToOutputStream(in, System.out);

与排球

KeyPinStore keystore = KeyPinStore.getInstance();
SSLSocketFactory sslSF = keystore.getContext().getSocketFactory();
RequestQueue mRequestQueue = Volley.newRequestQueue(context, new HurlStack(null, sslSF));

请注意使用正确的 CA 证书(不要使用站点证书): You have to select the CA certificate, not the site certificate
