Perl脚本不是在HTML表单执行 [英] Perl script is not executing in HTML form
问题描述
我在命名为铬（/home/chankey/Desktop/Chrome/guestbook.htm），其内容如下 guestbook.htm 文件p>
I have a guestbook.htm file in the directory named as Chrome (/home/chankey/Desktop/Chrome/guestbook.htm) whose content is given below
<html>
<head>
<title>Guestbook</title>
</head>
<body>
<form action="/home/chankey/Desktop/Chrome/guestbook.pl" method="get">
<table>
<tr><td>Name</td><td><input name="name" type="text" value=""></td></tr>
<tr><td>E-Mail</td><td><input name="email" type="text" value=""></td></tr>
<tr><td>Location</td><td><input name="loc" type="text" value=""></td></tr>
<tr><td>Comments</td><td>
<TEXTAREA name="comments" rows="10" cols="32"></TEXTAREA></td></tr>
</table><br><br>
<input type="submit" value="Add Entry">
</form>
</body>
</html>
在同一个chrome目录我有一个文件guestbook.pl，其内容是
In the same Chrome directory I have one file "guestbook.pl" whose content is
#!/usr/bin/perl
my $query_string = "";
#Get the input
if ($ENV{REQUEST_METHOD} eq 'POST') {
read(STDIN, $query_string, $ENV{CONTENT_LENGTH});
} else {
$query_string = $ENV{QUERY_STRING};
}
##### We will remove this
print "Content-Type: text/html\n\n";
print "Query String is \n<br> $query_string";
##### We will remove this
当我执行出现了一个形式guestbook.htm文件，当我填写资料，并点击添加条目按钮，一个新页面打开会出现完整的脚本在哪里。
When I am executing the guestbook.htm file there appears a form, when I fill the data and click on "Add Entry" button a new page opens where the complete script appears.
即。脚本guestbook.pl没有执行。我想知道这背后的原因是什么？为什么脚本不执行？ （我已经给执行权限在此文件）。
i.e. the script "guestbook.pl" is not executing. May I know the reason behind this? Why the script is not executing? (I have already given executing permission to this file).
在httpd.conf文件我已经加入
In the httpd.conf file I have added
AddHandler cgi-script cgi pl
<Directory /home/chankey/Desktop/Chrome/>
Options +ExecCGI
</Directory>
仍是不执行。让我知道原因。
Still it is not executing. Let me know the reason.
推荐答案
当您访问本地文件（在文件：// 在浏览器中键入URL）它不是从网络服务器上运行，所以
When you access a file locally (over the file:// type URL in your browser), it's not running from a web server, so:
- 没有CGI环境
- 的
的httpd.conf/的.htaccess文件没有任何效果
- There is no CGI environment
- The
httpd.conf/.htaccessfiles have no effect
有几个方法来处理这样的：
A few ways to deal with this:
- 创建
的public_html在您的家命名的文件夹。您的Web服务器可能有一个设置地图的http：//本地主机/〜chankey /到/家庭/ chankey /的public_html。 （MacOSX上，在preferred名为网站，相反，我相信。）在一个SELinux的系统，你必须专门授予权限的Apache使用此方法。 - 对于使用标准的
CGI包Perl脚本的具体情况，也可以手动从终端shell中运行它们，它们的输出重定向到一个临时文件（如：＆GT; /tmp/output.html），然后您就可以访问 - 迁移的开发工作区到Web服务器自身的目录结构，一般
的/ var / www / html等/...
- Create a folder named
public_htmlin your home. Your web server likely has a setting to maphttp://localhost/~chankey/to/home/chankey/public_html. (On MacOSX, the preferred name isSites, instead, I believe.) On an SELinux system, you'll have to specifically grant permission for Apache to use this method. - For the specific case of Perl scripts using the standard
CGIpackage, you can also run them manually from a terminal shell, and redirect their output to a temporary file (e.g.>/tmp/output.html), which you can then access - Migrate your development workspace into your web server's own directory structure, typically
/var/www/html/…
PS /无关系：我强烈建议，如果你打算把这个在互联网上，你应该使用CGI;使用严格的;！并启用污点模式＃的/ usr / bin中/ perl的-WT ...
PS / unrelated: I strongly recommend that, if you plan to put this on the Internet, you should probably use CGI; use strict; and have the tainting mode enabled #!/usr/bin/perl -WT …
