vue2.0 如何在hash模式下实现微信分享

最近又把vue的demo拿出来整理下,正好要做“微信分享”功能,于是遇到新的问题;

由于hash模式下,带有“#”,导致微信分享的签证无效;当改成history的模式后,分享ok;

但是问题来了,history模式下相当操蛋:

  • 刷新页面,页面报错404;这不是扯犊子吗?【不过这个问题,可以在后台解决,这里就不说了】
  • assets下的img文件,引入路径失败;

对于上面的问题,我是直接不能忍啊,所以history模式是肯定不行的;我决定依旧用hash模式;history模式万万要不得

那么问题来了:怎么在hash模式下实现微信分享?

其实微信分享失败的问题,最重要的一步就是解决“#”的问题;

一般的页面,我们获取当前的url是酱紫操作的

let params = '&params=' + JSON.stringify({url: window.location.href});

SPA页面,我们需要做点小调整,调整的目的是让“#”say goodbye

let params = '&params=' + JSON.stringify({url: encodeURIComponent(window.location.href.split('#')[0])});

这样修改后,签名的url中没带“#”,这样就ok了,下面贴上完成的代码

<script>
// 微信分享
import configModel from "../models/config.model";
import elementService from "../services/element.service";

class ShareService{
 wxShare(succCb, cancelCb, errorCb){
  let baseUrl = 'http://q.letwx.com/api/jsapi?action=jscfg';
  let samekey = '&uid=' + configModel.uid + '&wxapiopenid=' + configModel.apiopenid + '&wxapitoken=' + configModel.apitoken + '&debug=nf';
  let params = '&params=' + JSON.stringify({url: encodeURIComponent(window.location.href.split('#')[0])}); // 这里是关键
  let url = baseUrl + params + samekey;
  $.post(url, data => {
   elementService.loadingHide();
   console.log(data);
   switch (data.error) {
    case 0:
     this.wxConfig(data.cfg, configModel.shareInfo, succCb, cancelCb, errorCb);
     break;
    default:
     elementService.message(data.error_msg, 'error');
     break;
   }
  }, 'json');
 }
 wxConfig(wxconfig, share, succCb, cancelCb, errorCb){
  wx.config({
   debug: false,
   appId: wxconfig.appId,
   timestamp: wxconfig.timestamp,
   nonceStr: wxconfig.nonceStr,
   signature: wxconfig.signature,
   jsApiList: [
    'onMenuShareTimeline',
    'onMenuShareAppMessage',
    'onMenuShareQQ',
    'onMenuShareWeibo'
   ]
  });
  wx.ready(function() {
   wx.onMenuShareAppMessage({ //朋友
    title: share.title,
    desc: share.desc,
    link: share.link,
    imgUrl: share.imgUrl,
    success: function() {
     succCb && succCb();
    },
    cancel: function() {
     cancelCb && cancelCb();
    }
   });
   wx.onMenuShareTimeline({ //朋友圈
    title: share.desc,
    link: share.link,
    imgUrl: share.imgUrl,
    success: function() {
     succCb && succCb();
    },
    cancel: function() {
     cancelCb && cancelCb();
    }
   });
   wx.onMenuShareQQ({ //QQ
    title: share.title,
    desc: share.desc,
    link: share.link,
    imgUrl: share.imgUrl,
    success: function() {
     succCb && succCb();
    },
    cancel: function() {
     cancelCb && cancelCb();
    }
   });
   wx.onMenuShareWeibo({ //QQ
    title: share.title,
    desc: share.desc,
    link: share.link,
    imgUrl: share.imgUrl,
    success: function() {
     succCb && succCb();
    },
    cancel: function() {
     cancelCb && cancelCb();
    }
   });
  });
  wx.error(function(res) {
   console.log(res);
   errorCb && errorCb(JSON.stringify(res));
  });
 }
}

let shareSerivice = new ShareService();
export default shareSerivice;
