昨天按照 hexo-theme-next/LEANCLOUD-COUNTER-SECURITY.md at master · theme-next/hexo-theme-next 这个文档配置博客阅读次数时，遇到 hexo-leancloud-counter-security 插件的一个冲突。

完成配置使用 hexo -d 时，终端中出现下面的错误提示：

 ATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html

看提示貌似是利用 Json 解析字符串的时候出现问题。打开 node_modules/hexo-leancloud-counter-security/index.js:92，对应出现一个解析 JSON的：

y = JSON.parse(memoData[memoIdx].substring(0, memoData[memoIdx].length - 1));

js 没有怎么接触过，不知道能不能单步调试之类的，只好祭出输出调试大法，加上两个输出：

console.log(memoIdx)
console.log(memoData[memoIdx])
y = JSON.parse(memoData[memoIdx].substring(0,memoData[memoIdx].length - 1));

然后再执行 hexo -d 命令，命令行输出为： 

28
{"title":"System.out.println("hello world!");","url":"/post/hello-world.html"},

JSON 在解析字符串{"title":"System.out.println("hello world!");","url":"/post/hello-world.html"} 时出现错误。对应的正是之前写的一篇名为 System.out.println("hello world!"); 的文章，由于 JSON 格式中字符串是需要用"" 修饰，导致JSON 中出现了一个 "title":"System.out.println("hello world!");" key-value 组合。然而实际上 JSON 只会将 "System.out.println("h 解析成 value，之后出现的 h 被当成非法字符报错。

定位问题之后，暂时修改文章的标题为 hello world! | 算法花园，绕过部署失败。
