微信小程序 PHP生成带参数二维码

官方获取小程序页面API

由于小程序参数二维码API提供的帮助有限，以下是我对该功能的一些理解

我主要是通过thinkphp后台接口实现，代码如下：

1、先获取ACCESS_TOKEN：

$tokenUrl="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->secret;    $getArr=array();    $tokenArr=json_decode($this->send_post($tokenUrl,$getArr,"GET"));    $access_token=$tokenArr->access_token;

send_post:

function send_post($url, $post_data,$method='POST') {    $postdata = http_build_query($post_data);    $options = array(      'http' => array(        'method' => $method, //or GET        'header' => 'Content-type:application/x-www-form-urlencoded',        'content' => $postdata,        'timeout' => 15 * 60 // 超时时间（单位:s）      )    );    $context = stream_context_create($options);    $result = file_get_contents($url, false, $context);    return $result;  }

2、生成二维码：

$path="pages/index?query=1";    $width=430;    $post_data='{"path":"'.$path.'","width":'.$width.'}';    $url="https://api.weixin.qq.com/cgi-bin/wxaapp/createwxaqrcode?access_token=".$access_token;    $result=$this->api_notice_increment($url,$post_data);

api_notice_increment:

function api_notice_increment($url, $data){    $ch = curl_init();    $header = "Accept-Charset: utf-8";    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);    curl_setopt($curl, CURLOPT_HTTPHEADER, $header);    curl_setopt($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);    $tmpInfo = curl_exec($ch);    //     var_dump($tmpInfo);    //    exit;    if (curl_errno($ch)) {      return false;    }else{      // var_dump($tmpInfo);      return $tmpInfo;    }  }

3、根据返回的二进制数据生成图片并上传到自己的服务器

主要代码：
