小程序生成参数二维码（PHP）

官方获取小程序页面二维码API 小程序生成参数二维码（PHP）(图1)

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:

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;
}
}
