Debian Stretch に PHP5.6 と PHP7.0 を共存させる

Posted on | Tagged : ,

Summary

Debian StretchのオフィシャルリポジトリにはPHP5.6が含まれていない。
packages.sury.org のPHP5.6のパッケージを利用して、PHP5.6, PHP7.0 の環境を共存させたい。

sury.orgのgpgキーを追加

$ sudo apt-get install apt-transport-https
$ curl https://packages.sury.org/php/apt.gpg | sudo apt-key add -

- /etc/apt/sources.list.d/deb.sury.org.list
[src]
deb https://packages.sury.org/php/ stretch main


php5.6, php7.0のインストール

$ sudo apt-get update
$ sudo apt-get install php5.6-cli php5.6-fpm php7.0-cli php7.0-fpm


/etc/nginx/site-available/site-with-php7.0

server {
	listen 8870 default_server;
	listen [::]:8870 default_server;
	server_name _;
	root /var/www/site-with-php7.0;
	index index.php;
	location / {
		include snippets/fastcgi-php.conf;
		fastcgi_pass unix:/run/php/php7.0-fpm.sock; # adjust for the listen setting discussed above
	}
}

/etc/nginx/site-available/site-with-php5.6

server {
	listen 8856 default_server;
	listen [::]:8856 default_server;
	server_name _;
	root /var/www/site-with-php5.6;
	index index.php;
	location / {
		include snippets/fastcgi-php.conf;
		fastcgi_pass unix:/run/php/php5.6-fpm.sock; # adjust for the listen setting discussed above
	}
}

シンボリックリンクの作成, nginxの再起動

$ ln -s ../sites-available/site-with-php5.6 /etc/nginx/sites-enabled
$ ln -s ../sites-available/site-with-php7.0 /etc/nginx/sites-enabled
$ systemctl reload nginx.service

Mechanize でパースできないHTMLを強引に処理する

Posted on | Tagged :

Summary

Mechanizeは、HTML (Content-Type: text/html) をパースする際にMechanize::Pageを利用する。
しかし、パースするHTMLがwell-formedではない場合、パースに失敗する。

Mechanize::Page で処理

require 'mechanize'

agent = Mechanize.new
agent.pluggable_parser['text/html'] = PlainFile
page = agent.get("http://example.com/")
p page


#<Mechanize::Page
 {url #<URI::HTTP http://ill-formed.com/>}
 {meta_refresh}
 {title "ill-formed.com"}
 {iframes}
 {frames}
 {links}
 {forms}>

Plain Textで処理

require 'mechanize'

class PlainFile < Mechanize::File; end

agent = Mechanize.new
agent.pluggable_parser['text/html'] = PlainFile
page = agent.get("http://example.com/")
p page


#<PlainFile:0x00007fb8d2077910
 @body=
  "<!doctype html>\n" +
  "<html>\n" +
  "<head>\n" +
  "    <title>ill-formed.com</title>\n" +
  "\n" +
  "    <meta charset=\"utf-8\" />\n" +
  "    <meta http-equiv=\"Content-type\" content=\"text/html; charset=utf-8\" />\n" +
  "    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1\" />\n" +
  "\t<link rel=\"stylesheet\" type=\"text/css\" href=\"main.css\" />\n" +
  "</head>\n" +
  "\n" +
  "<body>\n" +
  "<div>\n" +
  "    <h1>ill-formed.com</h1>\n" +
  "\t<p>This domain is established to be used for ill-formed HTML test. <!-- </p> -->\n" +
  "<!-- </div> -->\n" +
  "<!-- </body> -->\n" +
