npm i jweixin-module

![20201103143840780.png][]

2，在需要分享的页面引入

3，设置分享内容（或者点击触发分享）

distributrShare() {
        this.$http({
            apiName: "wxJsdkConfig",
            type: "POST",
            data: {
                url: encodeURIComponent(window.location.href),
                //后台通过域名进行授权
            }
        }).then(res = >{
            var _self = this jweixin.config({
                debug: true,
                // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
                appId: res.data.appId,
                // 必填，公众号的唯一标识
                timestamp: res.data.timestamp,
                // 必填，生成签名的时间戳
                nonceStr: res.data.nonceStr,
                // 必填，生成签名的随机串
                signature: res.data.signature,
                // 必填，签名
                jsApiList: ['updateTimelineShareData', 'updateAppMessageShareData', ] // 必填，需要使用的JS接口列表
            })
    
            jweixin.ready(function(res) {
                //分享给朋友
                jweixin.updateAppMessageShareData({
                    title: _self.title,
                    desc: "快来嗨购吧！",
                    link: window.location.href + "&inviteCode=" + _self.userInfo.inviteCode,
                    imgUrl: _self.picUrl,
                    trigger: function trigger(res) {
                        // alert(res);
                    },
                    success: function success(res) {
    
                        // alert('已分享');
                    },
                    cancel: function cancel(res) {
                        // alert('已取消');
                    },
                    fail: function fail(res) {
                        // alert(2, JSON.stringify(res));
                    }
                });
            }) jweixin.error(err = >{
                // console.log("jsapi错误：",err)
            })
        }).
        catch(err = >{
            // console.log(3,err)
        })
    
    },

注意几点：

**a:公众号的分享只能通过右上角h5的分享触发，默认分享当前页面，分享只是配置分享内容 **

**b:当前分享页面的链接必须在后台配置JS接口安全域名和网页授权域名，**

**c:传到后台的链接需要****encodeURIComponent转码，不能包括端口号，**

**d:安卓上可以，IOS上报fail link must be in js secure domain list参考：[解决微信H5网页分享报错：fail link must be in js secure domain list][H5_fail link must be in js secure domain list]**

**e:invalid signature参考[关于微信公众号开发config:invalid signature错误的解决方法][config_invalid signature]**

### 二，授权登录 ###

页面：
