java - Android HttpURLConnection - 如何设置 HTTP/1.1 协议？

Question

如何使用 HttpURLConnection 将 HTTP 协议设置为 HTTP/1.1？

我使用的一些二传手：

    HttpsURLConnection httpsURLConnection = (HttpsURLConnection) url.openConnection();
    connection.setRequestProperty("Cache-Control", "max-age=0");
    connection.setRequestProperty("Connection", "keep-alive");
    connection.setRequestProperty("Keep-Alive", "300");
    connection.setRequestProperty("Accept-Charset", "UTF-8;q=1,ISO-8859-1;q=0.9,*;q=0.5");
