微信开发入门指南

以下为PHP接入微信平台开发 几个小例子，已经做了备注就不过多解释

public function getAllOpenid(){
        //获取token，请替换下边的编号和密匙，公众号后台有，每次token的请求都会改变，这里token是身份验证的根据
        $url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=编号&secret=密匙";         //根据微信提供接口获取
        $ch = curl_init();                                  //初始化一个 cURL 对象
        curl_setopt($ch, CURLOPT_URL, $url);                //设置你需要抓取的URL
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    //禁用后cURL将终止从服务端进行验证  
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);    //可以设置为验证站点
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        //返回原生的（Raw）输出 
        $output = curl_exec($ch);                           //抓取URL并把它传递给浏览器  
        curl_close($ch);                                    //关闭cURL资源，并且释放系统资源  
        $jsoninfo = json_decode($output, true);
        $access_token = $jsoninfo["access_token"];
        echo "$access_token";

        //获取单个用户信息

        $url="https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$access_token."&openid=oznizt77TsNMyl_6FQHVjZ_0pQBU&lang=zh_CN";

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($ch);
        curl_close($ch);
        $jsoninfo = json_decode($output, true);
        dump($jsoninfo);

        //批量获取用户信息[post]
        $url="https://api.weixin.qq.com/cgi-bin/user/info/batchget?access_token=".$access_token;
        $data[‘user_list‘][][‘openid‘]=‘ozniztzzpOFBVgdFxhkAUIIexvJ8‘;
        $data[‘user_list‘][][‘openid‘]=‘oznizt9TbEMLzc4km2ETKSPH5oQQ‘;

        $data=json_encode($data);
        $output=$this->curlGet($url,‘post‘,$data);
        $jsoninfo = json_decode($output, true);
        dump($jsoninfo);

        //获取用户列表
        $url="https://api.weixin.qq.com/cgi-bin/user/get?access_token=".$access_token."&next_openid=";
        $output=$this->curlGet($url);
        $jsoninfo = json_decode($output, true);
        dump($jsoninfo);


    }

    //以下为curl方法，上边三个可以用这个方法。
    function curlGet($url,$method=‘get‘,$data=‘‘){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, strtoupper($method));
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_USERAGENT, ‘Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)‘);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $temp = curl_exec($ch);
        return $temp;
    }
