微信公众号jssdk分享功能通用写法

前端JS通用代码

请注意传给后台的url是当前浏览器的地址并且进行encodeURIComponent处理： encodeURIComponent(location.href.split('#')[0]),而方法中的url则是用于分享到朋友圈或者微信好友的跳转链接。注：这里很多人会混淆

function WeChat(url, title, img, desc) {
    var configData = {
        title: title, // 分享标题
        desc: desc, // 分享描述
        link: url, // 分享链接
        imgUrl: img
    };
    $.ajax({
        url: basePath+'/wechat/wechatShare.ky',
        type: 'POST',
        data: {
        	url:encodeURIComponent(location.href.split('#')[0]),
        	debug:"false",
        	jsApiList:"onMenuShareAppMessage,onMenuShareTimeline"
        },
        async: false,
        success: function (resp) {
            if (resp.code=="00") {
            	console.log(resp.data);
                //wx.config(resp.data);
                wx.config(resp.data);
                
                wx.ready(function () {
					    
				     wx.onMenuShareAppMessage({ 
					        title: configData.title, // 分享标题
					        desc: configData.desc, // 分享描述
					        link: configData.link, // 分享链接，该链接域名或路径必须与当前页面对应的公众号JS安全域名一致
					        imgUrl: configData.imgUrl, // 分享图标
					        success: function () {
					            updateAppMessageShareData();
					        }
				      });

                		              
		              //分享给朋友圈
		              wx.onMenuShareTimeline({ 
					        title: configData.title, // 分享标题
					        link: configData.link, // 分享链接，该链接域名或路径必须与当前页面对应的公众号JS安全域名一致
					        imgUrl: configData.imgUrl, // 分享图标
					        success: function() {
					            updateTimelineShareData();
					        }
					      });

                    wx.error(function (res) {
                        alert(res.errMsg); //打印错误消息。及把 debug:false,设置为debug:ture就可以直接在网页上看到弹出的错误提示
                    });
                });
            } else {
                return;
            }
        },error:function(e){
            console.log(e);
        }
    });
}

公共方法调用

var url = "http://www.baidu.com/test";
var imgUrl =  responseData.imgUrl;
var title= responseData.title; 
var desc = responseData.desc;
WeChat(url, title, imgUrl, desc);

后台需要进行一次解码操作，记得加入微信工具包
