我怎样才能成为来自Apache 2缓冲CGI内容？ [英] How can I serve unbuffered CGI content from Apache 2?

问题描述

我想是能够允许用户查看一个长期运行GCI脚本的输出，因为它是生成而不是之后脚本完成。但是，即使当我明确地冲洗STDOUT服务器似乎等待脚本发送到客户端的响应之前完成。这是运行Apache 2.2.9在Linux服务器上。

I would like to be able to allow a user to view the output of a long-running GCI script as it is generated rather than after the script is complete. However even when I explicitly flush STDOUT the server seems to wait for the script to complete before sending the response to the client. This is on a Linux server running Apache 2.2.9.

例如CGI巨蟒：

#!/usr/bin/python

import time
import sys


print "Content-type: text/plain"
print
for i in range(1, 10):
        print i
        sys.stdout.flush()
        time.sleep(1)

print "Done."

在Perl中类似的例子：

Similar example in perl:

#!/usr/bin/perl

print "Content-type: text/plain\n\n";

for ($i = 1; $i <= 10 ; $i++) {
        print "$i\n";
        sleep(1);
}

print "Done.";

这个链接说像Apache 1.3 CGI输出应该是无缓冲（但这可能仅适用于Apache的1.x中）：<一href=\"http://httpd.apache.org/docs/1.3/misc/FAQ-F.html#nph-scripts\">http://httpd.apache.org/docs/1.3/misc/FAQ-F.html#nph-scripts

This link says as of Apache 1.3 CGI output should be unbuffered (but this might apply only to Apache 1.x): http://httpd.apache.org/docs/1.3/misc/FAQ-F.html#nph-scripts

任何想法？

推荐答案

兰德尔·施瓦茨的文章观看通过CGI 解释了不同的长流程（恕我直言，更好的）看长期运行的进程的方法。

Randal Schwartz's article Watching long processes through CGI explains a different (and IMHO, better) way of watching a long running process.
