Share the WeChat public account to realize the function of receiving membership cards

This article mainly introduces the relevant information on the WeChat public account to realize the membership card collection function. Friends who need it can refer to

1. The collection of membership cards also requires the js-sdk interface (you can refer to Obtaining WeChat The public account obtains the user’s geographical location information) (reference URL: http://gaoboy.com/article/25.html)

2. One more thing than obtaining the user’s geographical location information is that you need to obtain the signature package separately. , the signature method is also different from obtaining the user's geographical location (here we will talk about the method of obtaining the signature package)

Obtain the js-sdk signature package:

1. The current URL, timestamp, random string, JSAPITICKET for combination

#

 //调用js-sdk的签名包
 public function getSignPackage() {
 $jsapiTicket = $this->getJsApiTicket();
 // 注意 URL 一定要动态获取，不能 hardcode.（获取当前网页的url）
 $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
 //时间戳
 $timestamp = time();
 //随机字符串获取
 $nonceStr = $this->createNonceStr();
 // 这里参数的顺序要按照 key 值 ASCII 码升序排序
 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";
 //生成字符串是用来签名用的
 $signature = sha1($string);
 $signPackage = array(
  "appId"  => $this->appid,
  "nonceStr" => $nonceStr,
  "timestamp" => $timestamp,
  "url"  => $url,
  "signature" => $signature,
  "rawString" => $string
 );
 return $signPackage; 
 }

## 获##

//使用会员卡领取的签名包
 public function getHuiYuanSignPackage() {
 $apiTicket = $this->getApiTicket();
 // 注意 URL 一定要动态获取，不能 hardcode.（获取当前网页的url）
 $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
 //时间戳
 $timestamp = time();
 //随机字符串获取
 // $nonceStr = $this->createNonceStr();
 // 这里参数的顺序要按照 key 值 ASCII 码升序排序
 $string = $timestamp.$apiTicket."pVYA_t3RCVF_yhNcO6QCeAmb-1UI";
 //生成字符串是用来签名用的
 $signature = sha1($string);
 $signPackage = array(
  "timestamp" => $timestamp,
  "signature" => $signature,
 );
 return $signPackage; 
 }
