网站使用JS-SDK自定义微信分享内容实例
发布日期：2019年01月04日，网站分类：网站新闻
前几天朋友需要自定义微信分享内容，那时候没时间搞，大概的发了个微信的官方文档。今天来套简单的调用微信自带的JS-SDK，现在的思路已经很明确了，就是通过调用微信的JS-SDK实现自定义分享效果。
但是这个调用过程比较繁琐，需要提前准备如下东西：
1.微信认证服务号，2.网站域名
这个域名需要设置为微信公众号后台的JS接口安全域名，否则微信仍然不允许调用它的接口。
然后我们需要到公众号获取查看AppId，AppSecret以及绑定域名IP。
这里需要注意是http还是https，如果生产环境是https，务必前缀是https，都则会出现mix content这样的错误，导致引入失败。
<script typet="text/javascript" src="//res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
通过AppId和AppSecret请求accessToken,然后通过accessToken获取jsapi_ticket，生成config接口所需参数。
jssdk.php：
<?php
class wx_share {
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;
}

";制作成功后的效果图：
代码为核心代码，基本修改都是通用的，小白跳过，不要用客服系统问我，jsapi_ticket.json，access_token.json自己去搞，不多解释！
