这是我通过HTTP将文件发送到服务器的代码, 但我试图使用HTTPS进行传输我尝试使用参数传递值它正在工作,但我不知道如何使用文件流进行编码, 任何人都可以帮我这个我有证书

void Sending() {
        String iFileName = "video.mp4";
        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";
        String Tag = "fSnd";
        try {
            Log.e(Tag, "Starting Http File Sending to URL");

            // Open a HTTP connection to the URL



            HttpURLConnection conn = (HttpURLConnection) connectURL
                    .openConnection();          

            // Allow Inputs
            conn.setDoInput(true);

            // Allow Outputs
            conn.setDoOutput(true);

            // Don't use a cached copy.
            conn.setUseCaches(false);

            // Use a post method.
            conn.setRequestMethod("POST");

            conn.setRequestProperty("Connection", "Keep-Alive");

            conn.setRequestProperty("Content-Type",
                    "multipart/form-data;boundary=" + boundary);

            DataOutputStream dos = new DataOutputStream(conn.getOutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd);

花了一天时间发布到https安全连接, 最后找到了一个简单的方法,它只是将一个文件发布到服务器,但你可以循环发送尽可能多的你也可以用这个代码发送任何文件格式使它简单的人们享受
