node工程默认url_node.js处理url常用方法
let a= encodeURIComponent(str)//進(jìn)行編碼加密處理
let b = decodeURIComponent(a);//進(jìn)行解碼處理
解析urlvar http = require('http'),
urlApi= require('url'),

let url= urlApi.parse(request.url,true);
cosoleo.log(url);if(url.pathname=='/a.html'){
res.end('這里請(qǐng)求的是a.html，請(qǐng)求的參數(shù)是')
}
}
response.end('收到請(qǐng)求！');
}).listen(3000,()=>{
console.log('start')

let fs= require('fs');
let pathLib= require('path');
let formidable= reqiure('formidable');
let server= http.createServer((req,res)=>{
let urlObj= urlLib.parse(req.url,true);if(urlObj.pathname==='/'){

form.parse(req,function(err,fields,files){if(err)throwerr;
console.log(files);
let ext=pathLib.exname(files.wangpengde.name);
let oldPath=files.wangpengde.path;
let newPath= pathLib.join(_dirname,'/folder/')+files.wangpengde.name;
fs.rename(oldPath,newPath,(err)=>{if(err)throwerr;
console.log(ext);
res.writeHead(200,{'content-type':'text/plain;charset=UTF-8'});
res.write('成功！');
res.end();
})
})
}
})
server.listen(3000,()=>{
console.log('start');
})
三. http模塊
const http= require('http');
const cheerio= require('cheerio');
http.get('http://www.easyvoa.com',function(res){if(res.statusCode ==200){
let str= '';
res.on('data',(data)=>{
str+=data;
});
res.on('end',()=>{
const $=cheerio.load(str);
const titles= $('.title_a');for(let i = 0; i
console.log(titles.eq(i).text());
}
})
}
})
