java - Java 中的 curl HTTPS 实现

Question

如何将此 PHP 代码转换为 java？如何建立 HTTPS 连接？

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $to_post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
$result = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

我将它用于 HTTP，但我不能使用类似的东西

URL url = new URL("http://XZX");
            URLConnection con = url.openConnection();
            con.setDoInput(true);
            con.setConnectTimeout(40000);
            con.setDoOutput(true);
            con.setUseCaches(false);
            con.setDefaultUseCaches(false);
            // tell the web server what we are sending
            con.setRequestProperty("Content-Type", "text/xml;charset=\"utf-8\"");
            con.setRequestProperty("Accept", "text/xml");
            con.setRequestProperty("Cache-Control", "no-cache");
            con.setRequestProperty("Pragma", "no-cache");
            con.setRequestProperty("SOAPAction", "\"run\"");
            con.setRequestProperty("Content-length", String.valueOf(requestXml.length()));
            OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream());
            writer.write(requestXml);
            writer.flush();
            writer.close();
            InputStreamReader reader = new InputStreamReader(con.getInputStream());

您需要研究使用 Apache HTTP Components .这具有用 Java 发出 Web 请求所需的所有功能。

如果您不想使用 Apache 库，Java 有一个内置的 HttpsURConnection使用 HTTPS 进行连接的类。
