thinkphp5获取小程序码

基于获取小程序码保存到手机的需求，使用tp5进行后台的处理，下面是获取小程序码的方法：

//二维码生成

public function code()

{

$user_id = $this->uid;

$user = Users::where("user_id = $user_id")->find();

if($user['code_img']){

return $this->success($user['code_img']);

}else{

//获取token

$appID = "XXX";

$appSecret = "XXXXXXXXX";

$tokenUrl= "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&app>

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;

}

function api_notice_increment($url,$data)

{

$curl = curl_init();

$a = strlen($data);

$header = array("Content-Type: application/json; charset=utf-8","Content-Length: $a");

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($curl,CURLOPT_POST,1);

curl_setopt($curl,CURLOPT_POSTFIELDS,$data);

curl_setopt($curl, CURLOPT_HEADER, 0);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

$res = curl_exec($curl);

curl_close($curl);

return $res;

}

以上就是获取小程序码的方法
