Description
// 发送方
window.btoa()
// 接收方
window.atob()
window.btoa() 不支持中文, window.atob() 转换含有中文的 base64编码的时候中文部分会变为乱码
解决方案
function utf8_to_b64(str) {
return window.btoa(unescape(encodeURIComponent(str)));
}
function b64_to_utf8(str) {
return decodeURIComponent(escape(window.atob(str)));
}
// Usage:
utf8_to_b64('✓ à la mode'); // JTI1dTI3MTMlMjUyMCUyNUUwJTI1MjBsYSUyNTIwbW9kZQ==
b64_to_utf8('JTI1dTI3MTMlMjUyMCUyNUUwJTI1MjBsYSUyNTIwbW9kZQ=='); // "✓ à la mode"
utf8_to_b64('I \u2661 Unicode!'); // SSUyNTIwJTI1dTI2NjElMjUyMFVuaWNvZGUlMjUyMQ==
b64_to_utf8('SSUyNTIwJTI1dTI2NjElMjUyMFVuaWNvZGUlMjUyMQ=='); // "I ♡ Unicode!"
