聊聊Node中的url模块和querystring模块

const url = require("url");

const str = "Http://user:passWord@randy.com:8080/index.html?nick=%E4%B8%AD%E6%96%87#part=1";

const obj = url.parse(str);
console.log(obj);

const url = require("url");

const str = "http://user:password@randy.com:8080/index.html?nick=%E4%B8%AD%E6%96%87#part=1";

const obj2 = url.parse(str, true);
console.log(obj2);

const str2 = "//randy/nick";

const obj3 = url.parse(str2, true, false);
console.log(obj3);
const obj4 = url.parse(str2, true, true);
console.log(obj4);

const pathObj = {

};

console.log(url.fORMat(pathObj)); // http://user:password@randy.com:8080/index.html?nick=%E4%B8%AD%E6%96%87#part=1

console.log(url.resolve("/one/two/three", "four")); // /one/two/four

const querystring = require("querystring");

const str1 = "name-randy|country-cn";
const obj1 = querystring.parse(str1);
console.log(obj1); // { 'name-randy|country-cn': '' }
const obj2 = querystring.parse(str1, "|", "-");
console.log(obj2); // { name: 'randy', country: 'cn' }

const obj3 = {
  nick: "randy",
  age: "24",
};
const str4 = querystring.stringify(obj3);
console.log(str4); // nick=randy&age=24

const obj5 = {
  name: "randy",
  country: "cn",

const str6 = querystring.stringify(obj5, "|", "-");
console.log(str6); // name-randy|country-c
