l***y 发帖数: 4671 | 34 用 perl 开一个多线程,每个线程分别实时逐行报告状态,想既在屏幕上显示,又同时

狗了很多,最接近的办法是在线程里写:
sub mythread ($){
...
my $rc = system("myprogram blah blah blah | tee LOG_$_[0].txt");
...
}
这个方法的问题是没法实时逐行在屏幕上显示,而是把 myprogram 的输出分三次显示
出来。。。
为啥会分三次涅?。。。俺的c++ 程序里的输出命令都是 printf 啊,分别在三个
loops 里。大约长相是:

l***e 发帖数: 35 | 50 各位大虾,
在下需要写一java application,
以登陆一网站(当然有合法user/pass乐:)然后从此后的web page
截取有用信息并显示出来。
login部分已经通过,即可以从java app. POST username/passwd 到
server上的cgi program (perl),并获得返回的html page. (也就是
login后所见的第一页)
现在的问题是,login后,如何获得连接在第一页上的其他页??
尝试过在login后直接连接到从第一页上获得的url,但是不行,no
permission to access.
server的cgi是怎么确定一个url请求是否合法呢?session?
但是我login后得到的全部信息都是html code啊?到底如何用java实
现与server cgi的对话呢?
void URLReader(String targetURL)
{ //from javasoft.com
//retrieve a html page given its url
try {
