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

 //調(diào)用js-sdk的簽名包
 public function getSignPackage() {
 $jsapiTicket = $this->getJsApiTicket();
 // 注意 URL 一定要動態(tài)獲取，不能 hardcode.（獲取當(dāng)前網(wǎng)頁的url）
 $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
 //時間戳
 $timestamp = time();
 //隨機(jī)字符串獲取
 $nonceStr = $this->createNonceStr();
 // 這里參數(shù)的順序要按照 key 值 ASCII 碼升序排序
 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";
 //生成字符串是用來簽名用的
 $signature = sha1($string);
 $signPackage = array(
  "appId"  => $this->appid,
  "nonceStr" => $nonceStr,
  "timestamp" => $timestamp,
  "url"  => $url,
  "signature" => $signature,
  "rawString" => $string
 );
 return $signPackage; 
 }

//使用會員卡領(lǐng)取的簽名包
 public function getHuiYuanSignPackage() {
 $apiTicket = $this->getApiTicket();
 // 注意 URL 一定要動態(tài)獲取，不能 hardcode.（獲取當(dāng)前網(wǎng)頁的url）
 $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
 //時間戳
 $timestamp = time();
 //隨機(jī)字符串獲取
 // $nonceStr = $this->createNonceStr();
 // 這里參數(shù)的順序要按照 key 值 ASCII 碼升序排序
 $string = $timestamp.$apiTicket."pVYA_t3RCVF_yhNcO6QCeAmb-1UI";
 //生成字符串是用來簽名用的
 $signature = sha1($string);
 $signPackage = array(
  "timestamp" => $timestamp,
  "signature" => $signature,
 );
 return $signPackage; 
 }
