一个人如何用Meteor解析HTML服务器端? [英] How can one parse HTML server-side with Meteor?

问题描述

我希望能够将链接从我使用Meteor.http方法获取的HTML页面中抓取出来.在服务器端使用jQuery是理想的选择，但我认为这行不通.

I want to be able to scrape links out of an HTML page that I am fetching with the Meteor.http method. Would be ideal to use jQuery on the server-side but I don't think this works.

推荐答案

考虑使用 cheerio 像jquery，但更多用于抓取.我曾经尝试回答这个问题，所以我希望这次能做得更好.

Consider using cheerio its just like jquery but more for scraping. I have tried to answer this before so I hope I do a better job this time.

有一个npm模块，因此第一步需要在终端上安装它(在项目目录中):

its an npm module so first step install it (inside your project dir) with terminal:

meteor add http
cd .meteor
npm install cheerio

现在，代码:

您需要在服务器js/或等效版本中使用它

You need to use this in your server js/or equivalent

var cheerio = __meteor_bootstrap__.require('cheerio');
Meteor.methods({
last_action: function() {
       $ = cheerio.load(Meteor.http.get("https://github.com/meteor/meteor").content);
       return $('.commit-title').text().trim()      
    }
})

如果从客户端js运行此命令，则会在流星github分支上看到最后一个动作:

If you run this from your client side js, you will see the last action on meteors github branch:

Meteor.call("last_action",function(err,result){ console.log(result) } );

我从今天/2月23日起得到了这个

I got this as of today/feb 23rd

与github.com/meteor/meteor上的相同

which the same as on github.com/meteor/meteor
