篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了uniapp之h5公众号分享和授权相关的知识,希望对你有一定的参考价值。

一,微信分享

1,安装jweixin-module

npm i jweixin-module

 2,在需要分享的页面引入

<script>
	// #ifdef H5
	let jweixin = require('jweixin-module')
	// #endif
    
.....
</script>

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

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

二,授权登录

页面:

    // #ifdef H5 
    if (utils.isWxBrowser()) 
        if (window.location.href.includes('code='))

    // #endif
,
...

methods: 
    async oAuth(e) 
        // #ifdef H5
        if (utils.isWxBrowser()) 
            uni.showLoading(
                title: "授权中...",
                mask: true
            ) await this.wxJsdkLogin();
            uni.hideLoading()
        
        // #endif
