我正在尝试从Andorid版本4.1.1中的Android应用程序连接到URL,我收到了问题标题中指出的错误,但是当我尝试从Andorid版本4.0.4或3.1连接相同的URL时一切正常.

代码片段:

    try {
        .
        .
        .
        URL url = new URL(urlStr);
        Log.i(TAG,"[ URL ] " + urlStr);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        int size = conn.getContentLength();
        int responsecode = conn.getResponseCode();
        Log.d(TAG, "Responsecode: " + responsecode);
        .
        .
        .
        } catch (Exception e) {
        e.printStackTrace();
        }


private static void trustAllHosts() {

        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new java.security.cert.X509Certificate[] {};
            }

            public void checkClientTrusted(X509Certificate[] chain,
                            String authType) throws CertificateException {
            }

            public …

我正在尝试使用 OkHttp 库将发布请求发送到带有一些 url 参数的 API。在这篇博文之后，到目前为止我有这个代码：

    public String okHttpRequest() throws IOException{

        OkHttpClient client = new OkHttpClient();
        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        builder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {

                return true;
            }
        });
        HttpUrl.Builder urlBuilder = HttpUrl.parse("myurl").newBuilder();
        urlBuilder.addQueryParameter("username","username");
        urlBuilder.addQueryParameter("password","7777");
        String url = urlBuilder.build().toString();

        Request request = new Request.Builder()
                .url(url)
                .build();

        //HERE EXCEPTION IS THROWN
        Response response = client.newCall(request).execute(); 
        return response.body().string();
}

例外是：

javax.net.ssl.SSLPeerUnverifiedException: Hostname {domain} not verified:
