uni.share 暂不支持 share 方法 ?

uni.getProvider({  
                    service: 'share',  
                    success: function (res) {  
                        console.log(res.provider)  
                        if (~res.provider.indexOf('weixin')) {  
                           uni.share({  
                               provider: "weixin",
