ThinkPHP 调用微信JS-SDK

一:准备文件,并将文件置于网站根目录下
1、 access_token.json文件:{"access_token":"","expire_time":0}
2、jsapi_ticket.json文件:{"jsapi_ticket":"","expire_time":0}
3、jssdk.php文件(可在微信开发文档下载):
$this->appSecret = $appSecret;
}
public function getSignPackage() {
$jsapiTicket = $this->getJsApiTicket();
$url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$timestamp = time();
$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";
$signature = sha1($string);
$signPackage = array(
"appId" => $this->appId,
"nonceStr" => $nonceStr,
"timestamp" => $timestamp,
"url" => $url,
"signature" => $signature,
"rawString" => $string
);
return $signPackage;
}
private function createNonceStr($length = 16) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$str = "";
for ($i = 0; $i < $length; $i++) { $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1); } return $str; } private function getJsApiTicket() { // jsapi_ticket 应该全局存储与更新,以下代码以写入到文件中做示例 $data = json_decode(file_get_contents("jsapi_ticket.json")); if ($data->expire_time < time()) { $accessToken = $this->getAccessToken();
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";
$res = json_decode($this->httpGet($url));
$ticket = $res->ticket;
if ($ticket) {
$data->expire_time = time() + 7000;
$data->jsapi_ticket = $ticket;
$fp = fopen("jsapi_ticket.json", "w");
fwrite($fp, json_encode($data));
fclose($fp);
}
} else {
$ticket = $data->jsapi_ticket;
}
return $ticket;
}
private function getAccessToken() {
// access_token 应该全局存储与更新,以下代码以写入到文件中做示例
$data = json_decode(file_get_contents("access_token.json"));
if ($data->expire_time < time()) { $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret";
$res = json_decode($this->httpGet($url));
$access_token = $res->access_token;
if ($access_token) {
$data->expire_time = time() + 7000;
$data->access_token = $access_token;
$fp = fopen("access_token.json", "w");
fwrite($fp, json_encode($data));
fclose($fp);
}
} else {
$access_token = $data->access_token;
}
return $access_token;
}
private function httpGet($url) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_URL, $url);
$res = curl_exec($curl);
curl_close($curl);
return $res;
}
}

二:编辑显示页面对应的后台PHP文件,添加如下代码(用自己的微信账号信息)
include('jssdk.php');
$jssdk = new JSSDK("APPID", "APPSECRET");
$signPackage = $jssdk->GetSignPackage();

$this->signPackage = $signPackage;

三:编辑显示页面模板html文件,添加如下代码

到此已经能够正常进行微信自定义分享了
