perl-cgi命令行调试
参考: ?http://stackoverflow.com/questions/2224158/how-can-i-send-post-and-get-data-to-a-perl-cgi-script-via-the-command-line ? 一 一般地我们可以使用以下方法来检查cgi脚本的错误: 3)在命令行执行时可以交互式offline地输入cgi需要的参数, 此时cgi脚本中需要加入-debug参数 use CGI qw(-debug);,然后执行./calendar 且输入 month=jan year=2001,最后退出输入执行(use Ctrl-D on Unix or Mac; use Ctrl-Z on Windows) 。 ? 二 命令行执行cgi脚本的实例 1) 通过post方式来调用cgi脚本: $ echo -n 'a=b;c=d' | REQUEST_METHOD=POST CONTENT_LENGTH=999 perl index.cgi 通过get方式来调用cgi脚本: ? $ perl index.cgi 'a=b;c=d' ? ? 2) For example,with the following program (notice? #! /usr/bin/perl you feed it parameters on the command line: $ ./prog.cgi foo=bar baz=quux Content-type: text/plain foo => bar baz => quux You can also do so via the standard input: $ ./prog.cgi (offline mode: enter name=value pairs on standard input; press ^D or ^Z when done) foo=bar baz=quux ^D ? 3) 当用get方式时,设置环境变量?QUERY_STRING (实例在windows上)
set?QUERY_STRING=recipient=John
@Doe.com&Fullname=M+Name
perl?-w?scriptname.cgi ? 当用post方式时,需要将query_string的内容输入到临时文件testinput.txt,例如
echo?recipient=John
@Doe.com&Fullname=M+Name?>testinput.txt
perl?-w?scriptname.cgi?<?testinput.txt ? ? 三 来自perl cgi man page的帮助? If you are running the script from the command line or in the perl debugger,you can pass the script a list of keywords or parameter=value pairs on the command line or from standard input (you don't have to worry about tricking your script into reading from environment variables). You can pass keywords like this: your_script.pl keyword1 keyword2 keyword3 or this: your_script.pl keyword1+keyword2+keyword3 or this: your_script.pl name1=value1 name2=value2 or this: your_script.pl name1=value1&name2=value2 To turn off this feature,use the -no_debug pragma. To test the POST method,you may enable full debugging with the -debug pragma. This will allow you to feed newline-delimited name=value pairs to the script on standard input. When debugging,you can use quotes and backslashes to escape characters in the familiar shell manner,letting you place spaces and other funny characters in your parameter=value pairs: your_script.pl "name1='I am a long value'" "name2=two words" Finally,you can set the path info for the script by prefixing the first name/value parameter with the path followed by a question mark (?): ? ? your_script.pl /your/path/here?name1=value1&name2=value2? ? 完!
