WeChat official account to receive membership cards and public membership cards

The public account is used to receive membership cards.

1, membership card to receive also need js-sdk interface (can refer to get the public account to obtain the user's geographic location information) (Reference URL: http://gaoboy.com/article/25.html)

2. A signature package needs to be obtained separately, which is different from the method used to obtain the geographical location of a user (here we will talk about how to obtain the signature package)

Obtain the js-sdk signature package:

1. combine the current url, timestamp, random string, and jsapiticket

// Call the js-sdk signature package public function getSignPackage () {$ jsapiTicket = $ this-> getJsApiTicket (); // note that the URL must be dynamically obtained and cannot be hardcode. (get the url of the current webpage) $ protocol = (! Empty ($ _ SERVER ['https']) & $ _ SERVER ['https']! = 'Off' | $ _ SERVER ['server _ port'] = 443 )? "Https: //": "http: //"; $ url = "$ protocol $ _ SERVER [HTTP_HOST] $ _ SERVER [REQUEST_URI]"; // timestamp $ timestamp = time (); // obtain a random string $ nonceStr = $ this-> createNonceStr (); // The Order of parameters here should be sorted by the key value ASCII code in ascending order $ string = "jsapi_ticket = $ jsapiTicket & noncestr = $ nonceStr & timestamp = $ timestamp & url = $ url "; // The generated string is $ signature = sha1 ($ string) for signature; $ signPackage = array ("appId" => $ this-> appid, "nonceStr" => $ nonceStr, "timestamp" => $ timestamp, "url" => $ url, "signature" => $ signature, "rawString" => $ string); return $ signPackage ;}

Obtain the membership card signature package:

// Use the signature package public function getHuiYuanSignPackage () {$ apiTicket = $ this-> getApiTicket (); // note that the URL must be dynamically obtained and cannot be hardcode. (get the url of the current webpage) $ protocol = (! Empty ($ _ SERVER ['https']) & $ _ SERVER ['https']! = 'Off' | $ _ SERVER ['server _ port'] = 443 )? "Https: //": "http: //"; $ url = "$ protocol $ _ SERVER [HTTP_HOST] $ _ SERVER [REQUEST_URI]"; // timestamp $ timestamp = time (); // obtain a random string // $ nonceStr = $ this-> createNonceStr (); // here, the parameter order should be sorted by the key value ASCII code in ascending order $ string = $ timestamp. $ apiTicket. "pVYA_t3RCVF_yhNcO6QCeAmb-1UI"; // The generated string is $ signature = sha1 ($ string) for signature; $ signPackage = array ("timestamp" => $ timestamp, "signature" => $ signature,); return $ signPackage ;}

Code Description:

HTML page:

// Introduce the js file <script src = "http://res.wx.qq.com/open/js/jweixin-1.0.0.js"> </script> <script type = "text/JavaScript"> // configure the information verification interface (enter the js-sdk to obtain signature package parameters) wx. config ({debug: false, appId: '<? PHP echo $ signPackage ["appId"];?> ', Timestamp:' <? Php echo $ signPackage ["timestamp"];?> ', NonceStr:' <? Php echo $ signPackage ["nonceStr"];?> ', Signature:' <? Php echo $ signPackage ["signature"];?> ', JsApiList: [// All APIs to be called must be added to this list 'addcard']}); wx. ready (function () {// Add coupon document. querySelector ('# addCard '). onclick = function () {wx. addCard ({cardList: [{cardId: "", // id cardExt: '{"timestamp": "<? Php echo $ huiyuanPackage ['timestamp']?> "," Signature ":" <? Php echo $ huiyuanPackage ['signature']?> "} '// Signature package of the membership card}], // callback function after successful (whether the table database receives the membership card status through the callback function) success: function (res) {$. ajax ({url: '_ CONTROLLER _/editHuiYuan', type: 'post', ype: 'json', data: {is_LingQu: '1', user_id: "<? Php echo $ user ['user _ id']?> "}, Success: function () {$ (" # addCard ").html (" my membership card ") ;}}}) ;}); </script>
