微信分享不带图怎么办, 微信转发不带图怎么办, 怎么办怎么办
1, 微信公众平台申请 appId, SecKey, 开通 JSAPI
- <?php
- class JSSDK {
- private $appId;
- private $appSecret;
- public function __construct($appId, $appSecret) {
- $this->appId = $appId;

- $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
- );

- }

- header("Content-Security-Policy: script-src'self'; object-src'none';style-src cdn.example.org third-party.org; child-src https:");
- $jssdk = new JSSDK("app_id", "sec_key");
- $signPackage = $jssdk->GetSignPackage();
- echo json_encode($signPackage);
- exit;
2, 前端 导入:
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
3, 延迟加载
- $(function (){
- if (window.navigator.userAgent.toLowerCase().indexOf("micromessenger")> -1) {
- setTimeout("share_init()", 1000);
- }
- });
- function share_init()
- {
- $.ajax({
- url: '/wap/wx_jssdk.php',
- type:'get',
- data : {url : window.location.href},
- dataType:'json',
- success:function(result) {
- wx.config({
- debug: false,
- appId: result.appId,
- timestamp: result.timestamp,
- nonceStr: result.nonceStr,
- signature: result.signature,
- jsApiList: ["onMenuShareTimeline", "onMenuShareAppMessage"]
- });
- share_img_url = $(".product_detail_img")[0];
- wx.ready(function () {
- wx.onMenuShareTimeline({
- title: $(".goods-detail-name dt").text(),
- link: window.location.href,
- imgUrl: $(share_img_url).attr("src"),
- trigger: function (res) {
- },
- success: function (res) {
- },
- cancel: function (res) {
- },
- fail: function (res) {
- }
- });

- trigger: function (res) {

- success: function (res) {

- cancel: function (res) {

- });
- });
- }
- });
- }
