- 用thinkphp进行微信开发的整体设计思考
- http://www.2cto.com/weixin/201504/388423.html
我要投稿-
因为项目中很多地方都涉及到微信接口的调用 比如很多前台模块需要用到 后台模块也有少许调用 其他模块也可能会需要调用 为了让他们都能很方便的直接调用 我把他们独立成为一个模块 这个模块包含了基础的微信接口和微信jssdk
具体的设计请参考下面 当然如果有更好的建议可以共同交流
我先建立了一个新的模块叫Weixin 并在其下面建立了控制器BaseController 也就是一个微信类
这个微信基类 我是这样定义的
12345678910111213141516171819202122232425262728<?php/***微信开发的公共类（不含支付 如需要可自行加入）**/namespace Weixin\Controller;use Think\Controller;use Com\WechatAuth;use Com\Jssdk;classBaseControllerextendsController {public$appId;public$appSecret;public$WechatAuth;public$jssdk;publicfunction _initialize(){$config = F('DB_CONFIG_DATA');//获取配置信息if(!$config){$config = api('Config/lists');F('DB_CONFIG_DATA',$config);}C($config);//添加配置$this->appId = C('WEIXIN_CONFIG.appId');$this->appSecret = C('WEIXIN_CONFIG.appSecret');$this->WechatAuth =newWechatAuth($this->appId,$this->appSecret);$this->jssdk =newJssdk($appId,$appSecret);//调用微信Jssdk// $this->signPackage = $this->jssdk->GetSignPackage();}?>下面是我微信sdk包的部署目录结构供参考
这些部署好后 在任意模块中引入的方法是
1$Weixin =new\Weixin\Controller\BaseController();下面我用实例来讲述如何使用
1，获取用户信息（不管微信用户是否关注了公众号 下面代码大部分为注释内容 其实很少）
