一:准备设置js 借口安全域名:
这需要使用微信的jssdk,先需要在微信公众号后台进行设置:公众号设置–>功能设置–>JS接口安全域名。
二:前端配置
首先在前端页面引入jssdk 的js 文件
然后进行前端配置:
wx.config({
debug: true,//调试模式
appId: '',//
timestamp: <?php echo $signPackage["timestamp"];?>,//生成签名的时间戳
nonceStr: '',//生成签名的随机串
signature: '',
jsApiList: ['onMenuShareAppMessage','onMenuShareTimeline']// 所有要调用的 API 都要加到这个列表中
});
wx.ready(function() {
wx.onMenuShareAppMessage({ //分享给朋友
title: 'aa', // 分享标题,可在控制器端传递
desc: '非常舒适',//分享的描述,可在控制器端传递
link: 'URL', // 分享链接,可在控制器端传递
imgUrl: 'URL', // 分享图标 ,可在控制器端传递
success: function() {
// 用户确认分享后执行的回调函数
},
cancel: function() {
// 用户取消分享后执行的回调函数
}
});
wx.onMenuShareTimeline({ //分享到朋友圈
title: '分享的标题',
desc: '分享的描述',
link: 'url', // 分享链接
imgUrl: 'url', // 分享图标
success: function() {
// 用户确认分享后执行的回调函数
},
cancel: function() {
// 用户取消分享后执行的回调函数
}
});
});
</script>
timestamp: <?php echo $signPackage["timestamp"];?>,//生成签名的时间戳
nonceStr: '',//生成签名的随机串
signature: '',
jsApiList: ['onMenuShareAppMessage','onMenuShareTimeline']// 所有要调用的 API 都要加到这个列表中
});
wx.ready(function() {
wx.onMenuShareAppMessage({ //分享给朋友
title: '分享标题', // 分享标题,可在控制器端传递
desc: '分享描述',//分享的描述,可在控制器端传递
link: 'URL', // 分享链接,可在控制器端传递
imgUrl: 'URL', // 分享图标 ,可在控制器端传递
success: function() {
// 用户确认分享后执行的回调函数
},
cancel: function() {
// 用户取消分享后执行的回调函数
}
});
wx.onMenuShareTimeline({ //分享到朋友圈
title: '分享标题',
desc: '分享的描述',
link: 'url', // 分享链接
imgUrl: 'url', // 分享图标
success: function() {
// 用户确认分享后执行的回调函数
},
cancel: function() {
// 用户取消分享后执行的回调函数
}
});
});
</script>
三 后端php 代码:
<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
public function index(){
//分享朋友圈
$jssdk = new JSSDK("你的自己的appid", "你自己的appsecret");
$signPackage = $jssdk->GetSignPackage();
$this->assign('signPackage',$signPackage);
$this->display();
}
class JSSDK {
private $appId;
private $appSecret;
public function __construct($appId, $appSecret) {
$this->appId = $appId;
$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
// 转载文中,此处有错,需修改,看下方↓
// $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url";
$string = "jsapi_ticket=$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
$data = json_decode(file_get_contents("jsapi_ticket.json"));
if ($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;
}
}
