首先确保你的公众号配置没有问题，详细请看： PHP 微信公众号-创建菜单-配置
1、获取签名包
这里需要你的appid 和 开发者密码
//获取签名包
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
$tmpArr = array(
'noncestr' => $nonceStr,
'timestamp' => $timestamp,
'jsapi_ticket' => $jsapiTicket,
'url' => $url
); ksort($tmpArr, SORT_STRING);
$string1 = http_build_query( $tmpArr );
$string1 = urldecode( $string1 );
$signature = sha1( $string1 ); $signPackage = array(
"appId" => $this->appid,
"nonceStr" => $nonceStr,
"timestamp" => $timestamp,
"url" => $url,
"signature" => $signature,
"rawString" => $string1
);
return $signPackage;
} //获取jsapi_ticket
private function getJsApiTicket() {
if (S('jsapi_ticket_'.$this->appid)) {
$ticket = S('jsapi_ticket_'.$this->appid);
} else {
$accessToken = $this->getToken($this->appid, $this->appsecret);
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";
$res = $this->request_get($url);
$ticket = $res['ticket'];
if ($ticket) {
S('jsapi_ticket_'.$this->appid, $ticket, 7200);
}
}
return $ticket;
} /**
* @param $appid
* @param $appsecret
* @return mixed
* 获取token
*/
public function getToken($appid, $appsecret){
if (S($appid)) {
$access_token = S($appid);
} else {
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appid . "&secret=" . $appsecret;
$json = file_get_contents($url);
$result = json_decode($json);
$access_token = $result->access_token;
S($appid, $access_token, 7200);
}
return $access_token;
} /**
* 发送get请求
* @param string $url
* @return bool|mixed
*/
function request_get($url = ''){
if (empty($url)) {
return false;
}
$json = file_get_contents($url);
$result = json_decode($json,true);
return $result;
} public function createNonceStr($length = 16) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$str = "";
for ($i = 0; $i < $length; $i++) {
$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
}
return $str;
}
2、php控制器 配置图文消息内容，图片等。获取的签名包也要渲染到分享的页面
$invite = array(
"Title" => '标题',
"Description" => '摘要内容',
"PicUrl" => '图片地址',
"Url" => '要分享的页面（就是点击图文进入的页面）'
);
3、页面
首先要引入官方JS：jweixin-1.0.0.js
!function(a,b){"function"==typeof define&&(define.amd||define.cmd)?define(function(){return b(a)}):b(a,!0)}(this,function(a,b){function c(b,c,d){a.WeixinJSBridge?WeixinJSBridge.invoke(b,e(c),function(a){g(b,a,d)}):j(b,d)}function d(b,c,d){a.WeixinJSBridge?WeixinJSBridge.on(b,function(a){d&&d.trigger&&d.trigger(a),g(b,a,c)}):d?j(b,d):j(b,c)}function e(a){return
