一个关于微信公众号访问页面路径中带有中文参数导致微信分享到朋友圈功能失败问题的解决办法

访问路径:

本来访问路径

https://localhost:8080/fenchengcheng.jsp孩子

由于微信浏览器对中文进行编码了，所以导致了对中文进行了编码，访问路径变成了

https://localhost:8080/fenchengcheng.jspnickname=%E8%AE%BE%E7%BD%AE%E4%B8%AD%E6%96%87%E7%BC%96%E7%A0%81

在微信浏览器上这样的访问路径是无法进行分享的，具体原因不详，所以对于中文参数，要进行处理，不能直接传递中文。

我觉得有两种访问。1：对中文进行base64编码，在传参数 2.：通过浏览器缓存传参，不过方案一要更优。

一：base64传参:

1.base64编码:

            var i = 0;
            input = _utf8_encode(input);

方案二:

如果是特别重要的数据，不建议放入缓存，因为可以手动修改缓存内容

//放入缓存
    localStorage.setItem('nickname', '孩子');
    //从缓存中取出来
    localStorage.getItem('nickname');
