thinkphp 實現微信公衆號開發（一）

打算用php作一個微信公衆號管理平臺。用thinkphp框架

教程上面是是應用下面會自動生成Lib文件夾。可是個人3.2.3自動生成目錄不同

我修改了我項目文件夾下面的IndexController.class.php文件

D:\phpStudy\WWW\weixin\Imooc\Home\Controller\IndexController.class.php 

<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
 
    public function index(){
        $nonce = $_GET['nonce'];
        $token = 'imooc';
        $timestamp=$_GET['timestamp'];
        $echostr = $_GET['echostr'];
        $signature = $_GET['signature'];
        $array = array($nonce,$timestamp,$token);
        sort($array);

        $str = sha1(implode($array));
        if($str == $signature && $echostr){
            //第一次接入weixin api 接口的時候
            echo $echostr;
            exit;
        }else{
            $this->reponseMsg();
        }
    }
    public function  show(){
        echo 'imooc';
    }
}

 

在瀏覽器中輸入如下地址，能夠返回數據

http://localhost/weixin/index.php/Home/Index/show

微信中輸入 提交正常

URL(服務器地址) http://www.zzcit.com/weixin/index.php/Home/Index/index

以上證實了微信接口接入正常 

下面代碼則經過關注或者取消關注對用戶返回數據。微信開發之路正式開始 

<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
   /* public function index(){
        $this->show('<style type="text/css">*{ padding: 0; margin: 0; } div{ padding: 4px 48px;} body{ background: #fff; font-family: "微軟雅黑"; color: #333;font-size:24px} h1{ font-size: 100px; font-weight: normal; margin-bottom: 12px; } p{ line-height: 1.8em; font-size: 36px } a,a:hover{color:blue;}</style><div style="padding: 24px 48px;"> <h1>:)</h1><p>歡迎使用 <b>ThinkPHP</b>！</p><br/>版本 V{$Think.version}</div><script type="text/javascript" src="http://ad.topthink.com/Public/static/client.js"></script><thinkad id="ad_55e75dfae343f5a1"></thinkad><script type="text/javascript" src="http://tajs.qq.com/stats?sId=9347272" charset="UTF-8"></script>','utf-8');

        sort($array);
        //拼接成字符串,sha1加密 ，而後與signature進行校驗
