［已解决］swift中计算js的Base64.encode

需要Swift中去计算，类似于如下js中的Base64.encode的值：

function make_base_auth(user, password) {
var tok = user + ‘:’ + pass;
var hash = Base64.encode(tok);
return "Basic " + hash;
}

var auth = make_basic_auth(‘user-59e68fc0-39c3-4fb3-afef-7a7244d0e87d’,’password1′);

搜：

swift Base64 encode

代码：

import UIKit

let userId = "user-59e68fc0-39c3-4fb3-afef-7a7244d0e87d"
let password = "111111"

let tokenStr = userId + ":" + password
print("tokenStr=\(tokenStr)")

let tokenData = tokenStr.dataUsingEncoding(NSUTF8StringEncoding)
print("tokenData=\(tokenData)")

// let base64Str = tokenData?.base64EncodedDataWithOptions([])
let base64Str:String = (tokenData?.base64EncodedStringWithOptions([]))!

print("base64Str=\(base64Str)")

输出：

tokenStr=user-59e68fc0-39c3-4fb3-afef-7a7244d0e87d:111111

tokenData=Optional(<75736572 2d353965 36386663 302d3339 63332d34 6662332d 61666566 2d376137 32343464 30653837 643a3131 31313131>)

base64Str=dXNlci01OWU2OGZjMC0zOWMzLTRmYjMtYWZlZi03YTcyNDRkMGU4N2Q6MTExMTEx
