使用API​​时找不到证书路径的信任锚

Question

我正在制作新闻应用程序，并且正在使用newsapi.org来获取新闻。 我在模拟器和一台设备上尝试了我的应用程序，并且它可以正常运行，但是随后在另一台设备上尝试了此错误，我得到了此错误：引起原因：java.security.cert.CertificateException：java.security.cert.CertPathValidatorException：信任锚找不到认证路径。 有谁知道为什么会这样？ 提前致谢！

在Retrofit中将此方法与REtrofit 2配合使用，如图所示将其添加为客户端

public static OkHttpClient.Builder getUnsafeOkHttpClient() {

        try {
            // Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[]{
                    new X509TrustManager() {
                        @Override
                        public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                            return new java.security.cert.X509Certificate[]{};
                        }
                    }
            };

            // Install the all-trusting trust manager
            final SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());

            // Create an ssl socket factory with our all-trusting manager
            final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

            OkHttpClient.Builder builder = new OkHttpClient.Builder();
            builder.sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0]);
            builder.hostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            });
            return builder;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
