java - 将自定义证书添加到 OkHttp 客户端

Question

我正在尝试制作 Android 应用程序，我可以在其中获取和解析 HTML(来自没有 API 的网站)。我正在使用 OkHttp。该站点具有不受信任(但有效)的证书。我得到:

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

我已经设置了官方方式(https://developer.android.com/training/articles/security-ssl#java)，现在我需要将它与 OkHttpClient 链接。

我试过了

    OkHttpClient client = new OkHttpClient;

    OkHttpClient.Builder builder = client.newBuilder();
    builder.sslSocketFactory(sslcontext.getSocketFactory()).build();

但是它不起作用，而且它也被弃用了。谢谢

请参阅此文档示例以添加已知的受信任证书

https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/CustomTrust.java

  public CustomTrust() {
    X509TrustManager trustManager;
    SSLSocketFactory sslSocketFactory;
    try {
      trustManager = trustManagerForCertificates(trustedCertificatesInputStream());
      SSLContext sslContext = SSLContext.getInstance("TLS");
      sslContext.init(null, new TrustManager[] { trustManager }, null);
      sslSocketFactory = sslContext.getSocketFactory();
    } catch (GeneralSecurityException e) {
      throw new RuntimeException(e);
    }

    client = new OkHttpClient.Builder()
        .sslSocketFactory(sslSocketFactory, trustManager)
        .build();
  }
