nodejs 設定中文cookie無效

通過koajs的cookies方法設定cookie時,寫了中文的cookie值,一直失敗。程式碼如下:
this.cookies.set('test', '我是koajs')
報錯如下:
sent error argument value is invalid to the cloud
TypeError: argument value is invalid

倒騰了半夜也沒找到方案,其實是http協議的Header頭有字元限制,下圖是stackoverflow的解答,http的header字符集支援US-ASCII子集的字符集,故設定中文是'utf8'時就會報上面錯誤。

故解決方案:
把字串轉成base64即可
this.cookies.set('test', new Buffer('我是koajs').toString('base64'))
base64轉到字串
new Buffer(str, 'base64').toString();//str是base64編碼的字串
