我使用此端Self signed SSL
的SSL套接字和Trustmanager但我不断收到以下错误:
09-28 19:52:41.942:WARN / System.err(10101):javax.net.ssl.SSLHandshakeException:org.bouncycastle.jce.exception.ExtCertPathValidatorException:无法验证证书签名。
有什么问题? 我已经在stackoverflow上检查了不同的帖子,但我似乎无法让它工作。
我的代码:
SchemeRegistry schemeRegistry = new SchemeRegistry();
// http scheme
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
// https scheme
schemeRegistry.register(new Scheme("https", new EasySSLSocketFactory(), 443));
params = new BasicHttpParams();
params.setParameter(ConnManagerPNames.MAX_TOTAL_CONNECTIONS, 1);
params.setParameter(ConnManagerPNames.MAX_CONNECTIONS_PER_ROUTE, new ConnPerRouteBean(1));
params.setParameter(HttpProtocolParams.USE_EXPECT_CONTINUE, false);
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "utf8");
CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(new AuthScope("www.example.com", AuthScope.ANY_PORT),
new UsernamePasswordCredentials("user", "password"));
clientConnectionManager = new ThreadSafeClientConnManager(params, schemeRegistry);
context = new BasicHttpContext();
context.setAttribute("http.auth.credentials-provider", credentialsProvider);
DefaultHttpClient client = new DefaultHttpClient(clientConnectionManager, params);
HttpGet get = new HttpGet("https://www.example.com/web/restricted/form/formelement=512663");
HttpResponse response = client.execute(get, context);
Log.w("Response ","Status line : "+ response.toString());

正如迈克尔·列维所提到的,我之所以遇到这个例外的原因是我已经让我的Android模拟器开放了几天而且时钟已经远远不同步了。一旦我重新启动模拟器,异常就消失了。

很可能服务器返回了您不信任的权限的证书链。 (表示:您的设备不知道授权证书是否可信) 解决方案:仔细检查来自HTTPS网站的证书,并将相应的权限添加到您的信任库 - 但这部分似乎很棘手

就我而言,在Android 4和5上出现了以下错误:
原因: com.android.org.bouncycastle.jce.exception.ExtCertPathValidatorException: 无法验证证书:证书于5月30日星期六过期 10:48:38 GMT + 00:00 2020(相比之下,星期四8月13日11:47:00 GMT + 00:00 2020)
...
原因:java.security.cert.CertificateExpiredException: 证书于2020年5月30日星期六10:48:38 GMT + 00:00过期(与 星期四,八月13日11:47:00 GMT + 00:00 2020)
服务器出现证书错误(可能已过期)。
有关Retrofit
的信息,请参见https://stackoverflow.com/a/60507560/2914140。如果您将Fuel
用作REST库,请参见kotlin library that can do httpS connection without certificate verification (like curl --insecure)。
您可以信任所有证书,但这很危险。

注意:不同手机中的错误可能会略有不同。有些人可能会证明证书已过期。
答案 4 :(得分:0)
检查设备的时间,进行更正,然后再次检查。
