这是我在 http 服务器上向 servlet 发出 post 请求的代码

private static void post(String endpoint, Map<String, String> params)
        throws IOException {
    URL url;
    try {
        url = new URL(endpoint);
    } catch (MalformedURLException e) {
        throw new IllegalArgumentException("invalid url: " + endpoint);
    }
    StringBuilder bodyBuilder = new StringBuilder();
    Iterator<Entry<String, String>> iterator = params.entrySet().iterator();
    // constructs the POST body using the parameters
    while (iterator.hasNext()) {
        Entry<String, String> param = iterator.next();
        bodyBuilder.append(param.getKey()).append('=')
                .append(param.getValue());
        if (iterator.hasNext()) {
            bodyBuilder.append('&');
        }
    }
    String body = bodyBuilder.toString();
    Log.v(TAG, "Posting '" + body + "' to " + url);
    byte[] bytes = body.getBytes();
    HttpURLConnection conn = null;


    try {
        conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setUseCaches(false);
        conn.setFixedLengthStreamingMode(bytes.length);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded;charset=UTF-8");
        // post the request
        OutputStream out = conn.getOutputStream();
        out.write(bytes);
        out.close();
        // handle the response
        int status = conn.getResponseCode();
        if (status != 200) {
          throw new IOException("Post failed with error code " + status);
        }
    } finally {
        if (conn != null) {
            conn.disconnect();
        }
    }
  }

当我的端点就像 http://myipaddress:myport/ 它运行良好但是当我将它更改为 https 连接时它不起作用我也读过HttpsURLConnection但我不知道如何在那里实现它写了这段代码：

KeyStore keyStore = ...;
   TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
   tmf.init(keyStore);

   SSLContext context = SSLContext.getInstance("TLS");
   context.init(null, tmf.getTrustManagers(), null);

   URL url = new URL("https://www.example.com/");
   HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
   urlConnection.setSSLSocketFactory(context.getSocketFactory());
   InputStream in = urlConnection.getInputStream();

但是我无法获得 Keystore 中应该包含的内容，我只有文件文件，如果我使用 Keystore.getInstance(String type) 如何获取证书类型。

请帮帮我。

请检查此以向安全服务器发出发布请求
