js encode 原理

// 使用 encodeURI 对整个URL进行编码
let uri = "https://example.com/search?q=JavaScript教程";
let encodedURI = encodeURI(uri);
console.log(encodedURI); // 输出: https://example.com/search?q=JavaScript%E6%95%99%E7%A8%8B

// 使用 encodeURIComponent 对查询参数进行编码
let param = "JavaScript教程";
let encodedParam = encodeURIComponent(param);
console.log(encodedParam); // 输出: JavaScript%E6%95%99%E7%A8%8B

// 构建新的URL
let newUrl = `https://example.com/search?q=${encodedParam}`;
console.log(newUrl); // 输出: https://example.com/search?q=JavaScript%E6%95%99%E7%A8%8B

let urlWithSpaces = "https://example.com/search?q=JavaScript 教程";
let encodedUrl = encodeURI(urlWithSpaces);
console.log(encodedUrl); // 输出可能包含 '+'

// 使用 encodeURIComponent 解决空格问题
let encodedParamWithSpaces = encodeURIComponent("JavaScript 教程");
console.log(encodedParamWithSpaces); // 输出: JavaScript%20%E6%95%99%E7%A8%8B
