使用retrofit call添加自签名证书

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(null, null);
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");

// 加载自签名证书文件
InputStream inputStream = context.getResources().openRawResource(R.raw.self_signed_certificate);
Certificate certificate = certificateFactory.generateCertificate(inputStream);
keyStore.setCertificateEntry("self_signed_certificate", certificate);

// 创建TrustManager并初始化
trustManagerFactory.init(keyStore);
TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustManagers, new SecureRandom());

OkHttpClient okHttpClient = new OkHttpClient.Builder()
    .sslSocketFactory(sslContext.getSocketFactory(), (X509TrustManager) trustManagers[0])
    .build();

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .client(okHttpClient)
    .build();
