Android volley 错误 : "Trust anchor for certification path not found", 仅在真实设备中，而不是模拟器

Question

我的 Android 应用程序出现问题，在我使用 volley 执行网络请求的 fragment 之一中:

JsonObjectRequest request = new JsonObjectRequest(
            Request.Method.POST,
            CustomNetworkManager.getInstance(this.getActivity().getApplicationContext()).getRequestUrl(url),
            requestData,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    // process response
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d("FeedFragment", "Volley error: " + error.toString());
                }
            });

在真实设备上我收到以下错误(运行 API23):

D/FeedFragment: Volley error: com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

在运行相同 API 版本的 AVD 中，它工作正常。我检查了其他类似的主题，但找不到答案。

感谢您的帮助。

Answer 1

尝试将此功能添加到您的应用程序中:

    /**
     * Enables https connections
     */
    @SuppressLint("TrulyRandom")
    public static void handleSSLHandshake() {
        try {
            TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }

                @Override
                public void checkClientTrusted(X509Certificate[] certs, String authType) {
                }

                @Override
                public void checkServerTrusted(X509Certificate[] certs, String authType) {
                }
            }};

            SSLContext sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCerts, new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
            HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String arg0, SSLSession arg1) {
                    return true;
                }
            });
        } catch (Exception ignored) {
        }
    }

然后在您的应用程序 onCreate 中调用它。
