一：准备文件，并将文件置于网站根目录下 access_token.json
{"access_token":"","expire_time":0}
jsapi_ticket.json
{"jsapi_ticket":"","expire_time":0}
jssdk.php <?php
class JSSDK {
private $appId;
private $appSecret;
public function __construct($appId, $appSecret) {
$this->appId = $appId;
$this->appSecret = $appSecret;
}
public function getSignPackage() {
$jsapiTicket = $this->getJsApiTicket();
// 注意 URL 一定要动态获取，不能 hardcode.
$protocol = (!empty($_SERVER[‘HTTPS‘]) && $_SERVER[‘HTTPS‘] !== ‘off‘ || $_SERVER[‘SERVER_PORT‘] == 443) ? "https://" : "http://";
$url = "$protocol$_SERVER[HTTP_HOST]$_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=$nonceStr×tamp=$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
$data = json_decode($this->get_php_file("jsapi_ticket.php"));
if ($data->expire_time < time()) {
$accessToken = $this->getAccessToken();
// 如果是企业号用以下 URL 获取 ticket
// $url = "https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token=$accessToken";
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";
$res = json_decode($this->httpGet($url));
$ticket = $res->ticket;
if ($ticket) {
$data->expire_time = time() + 7000;
$data->jsapi_ticket = $ticket;
$this->set_php_file("jsapi_ticket.php", json_encode($data));
}
} 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
$data = json_decode($this->get_php_file("access_token.php"));
if ($data->expire_time < time()) {
// 如果是企业号用以下URL获取access_token
// $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$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;
$this->set_php_file("access_token.php", json_encode($data));
}
} else {
$access_token = $data->access_token;
}
return $access_token;
}
private function httpGet($url) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
// 为保证第三方服务器与微信服务器之间数据传输的安全性，所有微信接口采用https方式调用，必须使用下面2行代码打开ssl安全校验。
// 如果在部署过程中代码在此处验证失败，请到 http://curl.haxx.se/ca/cacert.pem 下载新的证书判别文件。
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);
curl_setopt($curl, CURLOPT_URL, $url);
$res = curl_exec($curl);
curl_close($curl);
return $res;
}
private function get_php_file($filename) {
return trim(substr(file_get_contents($filename), 15));
}
private function set_php_file($filename, $content) {
$fp = fopen($filename, "w");
fwrite($fp, "<?php exit();?>" . $content);
fclose($fp);
}
}
二：编辑显示页面对应的后台PHP文件，添加如下代码 jssdk.php 我放在verdor/weixin/ 下面
Vendor(‘weixin.jssdk‘);
$jssdk = new JSSDK("APPID", "APPSECRET");
$signPackage = $jssdk->GetSignPackage();
$this->signPackage = $signPackage;
三：在需要页面上或公共js里（所有页面）
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script>
wx.config({
appId: ‘{suetech:$signPackage.appId}‘,
timestamp: {suetech:$signPackage.timestamp},
nonceStr: ‘{suetech:$signPackage.nonceStr}‘,
signature: ‘{suetech:$signPackage.signature}‘,
jsApiList: [
‘checkJsApi‘,
‘onMenuShareTimeline‘,
‘onMenuShareAppMessage‘,
‘onMenuShareQQ‘,
‘onMenuShareWeibo‘
]
});
/*
* 注意：
* 1. 所有的JS接口只能在公众号绑定的域名下调用，公众号开发者需要先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。
* 2. 如果发现在 Android 不能分享自定义内容，请到官网下载最新的包覆盖安装，Android 自定义分享接口需升级至 6.0.2.58 版本及以上。

wx.ready(function () {
// 1 判断当前版本是否支持指定 JS 接口，支持批量判断
wx.checkJsApi({
jsApiList: [
‘getNetworkType‘,
‘previewImage‘,
‘onMenuShareTimeline‘,
‘onMenuShareAppMessage‘,
‘onMenuShareQQ‘,
‘onMenuShareWeibo‘
],
success: function (res) {
alert(JSON.stringify(res));
}
});
var shareData = {
title: ‘标题‘,
desc: ‘描述‘,
link: ‘链接‘,
imgUrl: ‘图片‘,
trigger: function (res) {
alert(‘用户点击发送给朋友‘);
},
success: function (res) {
alert(‘已分享‘);
},
cancel: function (res) {
alert(‘已取消‘);
},
fail: function (res) {

};
wx.onMenuShareAppMessage(shareData);
wx.onMenuShareTimeline(shareData);
wx.onMenuShareQQ(shareData);
wx.onMenuShareWeibo(shareData);
});
wx.error(function (res) {
alert(res.errMsg);
});
</script>
如果报错curl_setopt(): CURLOPT_SSL_VERIFYHOST with value 1 is deprecated and will be removed as of libcurl 7.28.1. It is recommended to use value 2 instead
修改
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);
为
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
需要注意的地方是在微信公众账号中配置您的域名，设置方法：
登陆微信公众账号->公众号设置->功能设置->JS接口安全域名->设置
