I. What is a plug-in?
? The plug-in is located in the/addons/plugins/directory.
? The plug-in extends some functions without modifying any application-core code and has the ability to enable and disable the plug-in.
? Thinksns plug-in mechanism is based on Hook, so the hook implemented by each plug-in will be executed once at the specified position. Multiple plug-ins will also execute in sequence when implementing the same Hook at the same time.

Ii. Development Process
????1: implement the description object of the Addons abstract class of the plug-in.
???? SimpleAddons: Simple plug-in
???? NormalAddons: complex plug-ins
?
??? Create the file name of the plug-in under plug-in/addons/plugins/(HttpReq is used below ).
??? The HttpReq directory structure is as follows:
?????????????? -Hook ??????????? Use hooks collection classes (multiple classes are allowed)
??????????? ? -Lib ???????????? Plug-in package
??????????? -Html ?? Plug-in page
?????????? -HttpReqAddons. class. php
????
??? Create a description file in the HttpReq Directory: HttpReqAddons. class. php
??? Note: This name must be a standard format such as plug-in name + Addons + class. php.
??? The Code is as follows :?

 
?
???? 2: Define the hooks collection class
? Create the HttpReqAddons. class. php class getHooksInfo under/addons/plugins/HttpReq/hook /.
HttpReqHooks class.
???? The Code is as follows:
  The request address for the sns request to obtain data * is as follows: http://whtest.com/index.php?app=home&mod=Widget&act=addonsRequest&addon=HttpReq&hook=get_user_face * @ Author tangw 2013-03-11 **/class HttpReqHooks extends Hooks {/*** obtain user information by user ID * @ author tangw 2013-03-11 * @ return josn object */public function get_user_info () {$ uid = $ _ REQUEST ['uid']; if (empty ($ uid) {$ this-> _ reJson (array ("isflag" => 0, "msg" => "request parameter error");} $ userData = M ('user')-> field ("email, uname ") -> where ("uid = $ uid")-> find (); if ($ userData) {$ this-> _ reJson (array ("isflag" => 1, "data" => $ userData);} e Lse {$ this-> _ reJson (array ("isflag" => 2, "msg" => "this user does not exist "));}} /*** obtain user images by user name ** @ author tangw 2013-03-11 * @ param array ("uname" => "username", "size" => "image size ") * @ return json object */public function get_user_face () {$ username = trim ($ _ REQUEST ['uname']); // username $ size = trim ($ _ REQUEST ['SIZE']); // image size s = small, m = middle, B = big $ size = empty ($ size )?
