调用腾讯云的OCR识别时，报错了。
var CryptoJS = require('crypto-js'); var now = parseInt(Date.now() / 1000), rdm = parseInt(Math.random() * Math.pow(2, 32)), plainText = 'a=' + appid + '&k=' + secretId + '&e=' + (now+pexpired) + '&t=' + now + '&r=' + rdm + userid + '&f=', data = new Buffer(plainText,'utf8'), res = CryptoJS.HmacSHA1(data, secretKey); var bin = Buffer.concat([res, data]); //这一句运行时报错了 var sign = bin.toString('base64'); return sign; |

不知道是什么原因？求解答！
varhmac = CryptoJS.HmacSHA1(CryptoJS.enc.Utf8.parse(plainText), CryptoJS.enc.Utf8.parse(secretKey))varsign = CryptoJS.enc.Base64.stringify(hmac.concat(CryptoJS.enc.Utf8.parse(plainText)))谢谢大神指导！
