Configuring the Apache Web Server to Run Perl 在Apache中运行Perl

Categories: Development Notes; Tagged with: Apache • CGI • httpd • Perl • Perl CGI; @ May 5th, 2012 16:22

1. Install Perl

2. Install Apache & config httpd：

Options Indexes FollowSymLinks
Add ExecCGI to this line. The line should now look like the following:
Options Indexes FollowSymLinks ExecCGI
Next, search for the following:
#AddHandler cgi-script .cgi
Uncomment this line by removing the # in front of the line, and add a .pl to the end of the line. The new line should look like this:
AddHandler cgi-script .cgi .pl

3. Start the server, and check the server environment:

http://localhost:8080/cgi-bin/printenv.pl

There should be some environment variables like DOCUMENT_ROOT/PATH/SCRIPT_FILENAME….

4. Drop a Perl(hello.pl) into the server：

#!D:/perl/bin/perl.exe print "Content-type: text/html; charset=utf-8\n\n"; print "<phtml><head><title>Learning Perl</title></head><body>"; print "<h1>PerlPage</h1>"; print "<form action='upload.pl' method='post'>"; print "<input type=file name=='file'>"; print "<input type=text name='comment' size=20 value=''>"; print "<input type=submit name=enter value='Upload'>"; print "<form>"; print "</body></html>";

you can just drop this file in your ApacheHome/cgi-bin or your site if you have configured the httpd.conf;

5. check the Perl page:

http://localhost:8080/cgi-bin/hello.pl

Apache Flex: MXML or ActionScript ?

Categories: Flex; Tagged with: ApacheFlex • Flex; @ April 22nd, 2012 21:59

Deciding to create components in MXML or ActionScript

One of the first decisions that you must make when creating custom components is deciding whether to write
them in MXML or in ActionScript. Ultimately, it is the requirements of your application that determine how you
develop your custom component.
Some basic guidelines include the following:

•MXML components and ActionScript components both define new ActionScript classes.
•Almost anything that you can do in a custom ActionScript custom component, you can also do in a custom MXML component. However, for simple components, such as components that modify the behavior of an existing component or add a basic feature to an existing component, it is simpler and faster to create them in MXML.
•When your new component is a composite component that contains other components, and you can express the positions and sizes of those other components using one of the Flex layout containers, you should use MXML to define your component.
•To modify the behavior of the component, such as the way a container lays out its children, use ActionScript.
•To create a visual component by creating a subclass from UIComponent, use ActionScript.
•To create a nonvisual component, such as a formatter, validator, or effect, use ActionScript.
•To add logging support to your control, use ActionScript. For more information, see “Logging” on page 227 in Building and Deploying Adobe Flex 3 Applications.

Flex3 官方文档中如上释疑. 2010年我参加Flex Developer Day时, 有开发者提问国内是否有大型企业应用实例? 未得到正面回答. 倒是群硕的团队还上台张扬了一把, 他们的项目大约是奥运时CCTV直播网站.

其实即便国内有大型的企业应用, 也不一定能获得足够价值的经验.

07年底开始做的教育应用, 大致有120W行代码, 其中有60%+的为AS代码, 除了入口文件及部分复杂UI使用MXML之外, 清一色都是AS代码, 所有的UI都小心谨慎的创建, 销毁. 在10年的DevDay时, 坐在我旁边的某研发他们也是纯AS.

几年过去了, Flex贡献给了Apache, Flex也已经4.6了, 接触的代码多了, 习惯了清纯的AS代码, 当满篇都是MXML标签时, 我不淡定了.

思想斗争良久, 到底孰优孰劣? 在多数common的情况下, 几乎不分上下. 我觉得AS代码更优雅更易读, 可人家说了: 我们可以Design, 不用代码, 一眼就看出来了…:(
