分享链接朋友圈带图标最新解决方案
分享链接朋友圈带图标最新解决⽅案
今天遇到要分享到的⽹站链接带图标的需求，⽹上查询了很多都是旧的接⼝，⼤部分都失效了，现在分享⼀下最新的详细解决⽅案。前提：需要⼀个企业
第⼀步，进⼊设置，配置js接⼝安全域名
第⼆步，配置IP⽩名单（填写站点服务器IP），获取AppID和AppSecret。
第三步，引⼊JS
<script src="res.wx.qq/open/js/jweixin-1.6.0.js"></script> <script>
var  url=location.href;
$.ajax({
type : "get",
url : "填写你的⽹址/js/jssdk.php?url="+url,
dataType : "jsonp",
jsonp: "callback",
jsonpCallback:"success_jsonpCallback",
success : function(data){
console.log(data)
debug: false,
appId: data.appId,
timestamp: data.timestamp,
nonceStr: Str,
signature: data.signature,
jsApiList: [
'updateAppMessageShareData', //分享到朋友圈
'updateTimelineShareData',//分享给朋友
]
});
},
error:function(data){
alert("连接失败！");
}
});
//分享到朋友圈
wx.updateTimelineShareData({
title: '这⾥填写标题',
link: url,
imgUrl: '这⾥填写图⽚路径',
success: function (res) {
}
})
wx.updateAppMessageShareData({
title: '这⾥填写标题',
desc: '这⾥填写描述',
link: url,
imgUrl:  '这⾥填写图⽚路径',
success: function (res) {
}
})
});
<(function (res) {
alert(res);
});
</script>
第四步，创建后端php⽂件，路径和上⾯引⼊地址⼀致即可，然后在当前⽬录下创建2个json⽂件 access_token.json ，jsapi_ticket.json，保证当前⽬录⽂件可写<?php
$url = $_GET['url'];
class JSSDK {
private $appId;
private $appSecret;
private $url;
public function __construct($appId, $appSecret,$url) {
$this->appId = $appId;
$this->appSecret = $appSecret;
$this->url = $url;
}
public function getSignPackage() {小红旗图标怎么弄
$jsapiTicket = $this->getJsApiTicket();
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "" : "";
// $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$url =$this->url;
$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,

"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();
// 如果是企业号⽤以下 URL 获取 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()) {
// 如果是企业号⽤以下URL获取access_token
// $url = "qyapi.weixin.qq/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";
$url = "api.weixin.qq/cgi-bin/token?grant_type=client_credential&appid=$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;
}
}
$jssdk = new JSSDK("填写你的AppID", "填写你的AppSecret",$url);
$signPackage = $jssdk->GetSignPackage();
$tmp=json_encode(array ('appId'=>$signPackage["appId"],'timestamp'=>$signPackage["timestamp"],'nonceStr'=>$signPackage["nonceStr"],'signature'=>$signPackage["signature"],'url'=>$signPackage["url"])); $callback = $_GET['callback'];
echo $callback.'('.$tmp.')';
exit;

最后实现效果
