Node.js中Express代码高亮highlight,bodyParser大小限制,nofollow搜索优化

node默认的post body参数的大小比较小,如果超过不做特殊处理的话，参数就会传不过去，那么怎样设置post body参数的大小呢？

I don't think this is the express global size limit, but specifically the connect.json middleware limit .

This is 100kb by default when you use express.bodyParser() and don't provide a limit option.

app.js 中设置下面的代码

app.use(bodyParser.json({limit: '2mb'}));

app.use(bodyParser.urlencoded({ limit: '2mb',extended: false, parameterLimit:2000 }));

通过marked配置代码高亮

npm install highlight.js

marked的配置中添加highlight项

var marked = require('marked');
var highlight = require('highlight.js');

marked.setOptions({
    renderer: new marked.Renderer(),
    gfm: true,
    tables: true,
    breaks: false,
    pedantic: false,
    sanitize: false,
    smartLists: true,
    smartypants: false,
    highlight: function (code) {
        //自动高亮
        return highlight.highlightAuto(code).value;
    }
});

页面添加

<link rel="stylesheet" href="/css/googlecode.min.css" />

搜索优化,链接加上nofollow

页面内容链接全部加上 nofollow,在marked.js中修改

var out = '<a href="' + href + '" rel="nofollow"';
