使用 ksoap2-android 不受信任的证书

Question

我正在使用 ksoap2-android 通过 SSL 调用 wcf 服务。我可以在没有 SSL 的情况下让它工作，但现在我想通过 SSL 进行调用，但我遇到了一些问题。

我使用 HttpsTransportSE 而不是 HttpTransportSE，但收到错误： javax.net.ssl.SSLException：不受信任的服务器证书

如何解决此问题？

能否将服务器证书添加到Android的Keystore中来解决这个问题？

private static final String SOAP_ACTION = "http://example.com/Service/GetInformation";
private static final String METHOD_NAME = "GetInformation";
private static final String NAMESPACE = "http://example.com";    
private static final String URL = "dev.example.com/Service.svc";

public static Result GetInformation()
{
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    PropertyInfo property = new PropertyInfo();
    property.name = "request";

    Request request =
        new Request("12", "13", "Ben");

    userInformationProperty.setValue(request);
    userInformationProperty.setType(request.getClass());
    request.addProperty(property);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    envelope.addMapping(NAMESPACE, "Request",new Request().getClass());

    HttpsTransportSE transport = new HttpsTransportSE(URL, 443, "", 1000);

    //HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    transport.debug = true;

    try
    {
        transport.call(SOAP_ACTION, envelope);          
        return Result.FromSoapResponse((SoapObject)envelope.getResponse());
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
    catch (XmlPullParserException e)
    {
        e.printStackTrace();
    }

    return null;
}

为了用一些源代码补充 Vedran 的答案，抱歉我无法发表评论。

trustManager：

private static TrustManager[] trustManagers;

public static class _FakeX509TrustManager implements
        javax.net.ssl.X509TrustManager {
    private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[] {};

    public void checkClientTrusted(X509Certificate[] arg0, String arg1)
            throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] arg0, String arg1)
            throws CertificateException {
    }

    public boolean isClientTrusted(X509Certificate[] chain) {
        return (true);
    }

    public boolean isServerTrusted(X509Certificate[] chain) {
        return (true);
    }

    public X509Certificate[] getAcceptedIssuers() {
        return (_AcceptedIssuers);
    }
}

public static void allowAllSSL() {

    javax.net.ssl.HttpsURLConnection
            .setDefaultHostnameVerifier(new HostnameVerifier() {
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            });

    javax.net.ssl.SSLContext context = null;

    if (trustManagers == null) {
        trustManagers = new javax.net.ssl.TrustManager[] { new _FakeX509TrustManager() };
    }

    try {
        context = javax.net.ssl.SSLContext.getInstance("TLS");
        context.init(null, trustManagers, new SecureRandom());
    } catch (NoSuchAlgorithmException e) {
        Log.e("allowAllSSL", e.toString());
    } catch (KeyManagementException e) {
        Log.e("allowAllSSL", e.toString());
    }
    javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(context
            .getSocketFactory());
}

调用您的方法：

allowAllSSL();
HttpsTransportSE httpsTransport = new HttpsTransportSE(Server,443, URL, 1000);

注意：

1. Server 是服务器 url。
2. 443 是默认的 https 端口，您仍然需要指定一个端口，因为构造函数需要一个端口。
3. URL WS 操作的路径
4. 1000 es 超时

构造如下：
[https://服务器:443/URL]

好吧，有一种更简单的方法可以做到这一点，而不是修改 HttpsServiceConnectionSE。您可以按照 http://groups.google.com/group/android-developers/browse_thread/thread/1ac2b851e07269ba/c7275f3b28ad8bbc?lnk=gst&q=certificate，然后在进行任何 SSL 通信之前调用allowAllSSL() /调用 ksoap2。它将注册一个新的默认 HostnameVerifier 和 TrustManager。 ksoap2 在进行 SSL 通信时，将使用默认的 SSL 通信，并且它的工作方式就像一个魅力。

我想，您还可以为此投入更多精力，使其（更加）安全，并在应用程序本地信任管理器中安装证书。我处于一个安全的网络中，并不害怕中间人攻击，所以我只做了第一个。

我发现有必要像这样使用 KeepAliveHttpsTransportSE new KeepAliveHttpsTransportSE(host, port, file, timeout);。这些参数进入 URL 对象，例如要访问 Jira 安装，类似于 new KeepAliveHttpsTransportSE("host.whatever", 443, "/rpc/soap/jirasoapservice-v2", 1000)。

有时，如果您对某项技术或 Web 服务不熟悉，您喜欢在 J2SE 环境中而不是在模拟器中甚至在设备上使用它，那么它会很方便，但在 J2SE/ME ksoap2 库中（KeepAlive）缺少 HttpsTransportSE 内容（我使用 ksoap2-j2se-full-2.1.2.jar）。您可以做的是从 Android 衍生品 ksoap2-android 获取 HttpsTransportSE、KeepAliveHttpsTransportSE 和 HttpsServiceConnectionSE 三个类的源代码，并将它们放入您的 J2SE 项目中并使用它们。它对我很有用，并且通过未知且相当复杂的 Web 服务迈出正确的第一步，这提高了生产力。

对我有用
