Nginx解决下载json静态文件乱码 Linux下采用的是utf-8的字符编码，默认情况下我们的浏览器在服务器没有指定编码或者静态页面没有声明编码的情况下会以GBK的编码去渲染页面，这样默认情况下返回中文的话浏览器用gbk来解析utf-8编码，显然会出现乱码，这时要在nginx location块中主动添加header来输出正确编码添加配置add_header Content-Type 'text/html; charset=utf-8';示例location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 7d; } location ~ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; add_header Content-Type 'text/html; charset=utf-8'; } }

如何在windows下升级node & npm upgrade nodenode有一个模块叫n，是专门用来管理node.js的版本的。 第一步：安装n模块： npm install -g n第二步： 升级node.js到最新稳定版 n stableBut，这在我的windows环境下报错： Google了一圈: (敲黑板！！)As stated in the readme file of that module, the module does not support Windows, hence the error you are getting. If you would like to update Node.js on Windows you can find binaries at https://nodejs.org/en/download/current/.于是乖乖去nodejs网站上下载.msi并安装，command line下成功，顺带着npm也一并更新了：
