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：

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 = '¶ms=' + 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 = '¶ms=' + 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 = '¶ms=' + 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;
