如何在Java中执行以下操作后才能使连接保持活动状态:
private static void makePostRequestAndPrintContent(String payload) throws IOException, InterruptedException{
URL url = new URL("url");
HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
con.setDoOutput(true);
con.setDoInput(true);
con.setInstanceFollowRedirects(true);
con.setRequestMethod("POST");
try( DataOutputStream wr = new DataOutputStream(con.getOutputStream())){
wr.write(convertPayloadToBytes(payload));
}
printContent(con);
}
printcontent():
private static void printContent(HttpsURLConnection con) throws InterruptedException{
if(con!=null){
try {
System.out.println("****** Content of the URL ********");
String input;
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
while ((input = br.readLine()) != null){
System.out.println(input);
}
br.close();
} catch (IOException e) {
e.printStackTrace();
}
在发布有效负载之后,我必须等待一段时间来从服务器进行PUT响应,但在执行后请求并从重定向站点读取内容后,连接将立即关闭(至少应用程序将被终止) 。 如何设置连接以等待进一步的响应,然后再次读取InputStream?
