使用 (上面的配置文件根据自己的需要写)
public function getSignPackage() { $sign = new SignatureService('service'); $result = $sign->getSignPackage(); return json($result); }
这是基于TP5写的 自己记录用 要是能看懂就拿走
SignatureService()方法里面的参数是区分不同公众号 这样也要有不同的配置文件
function share_disable(){ $.ajax({ type: 'GET', url: localurl + "/index.php/……/getSignPackage", data: {sign_url:encodeURIComponent(location.href.split('#')[0])}, dataType: 'JSON', success: function(data){ wx.config({ // debug :true, appId: data.appId, timestamp: data.timestamp, nonceStr: data.nonceStr, signature: data.signature, jsApiList: [ "hideMenuItems" ] }); wx.ready(function () { wx.hideMenuItems({ menuList: [ "menuItem:share:qq", "menuItem:share:timeline", "menuItem:share:appMessage", "menuItem:share:QZone", "menuItem:share:weiboApp", "menuItem:favorite", "menuItem:share:facebook", "menuItem:copyUrl", "menuItem:openWithQQBrowser", "menuItem:share:email", "menuItem:openWithSafari", "menuItem:originPage" ] // 要隐藏的菜单项,只能隐藏“传播类”和“保护类”按钮,所有menu项见附录3 }); }); } }); }
这是隐藏分享按钮的示例
