Python实现HMACSHA1生成加密签名

import json,hashlib,hmac,base64
 
def sign(data):
    date_new=''
    for key,value in sorted(data.items()):
        if key!="sign" and value:
            date_new+= key + "=" +str(value)+"&"
    sk="wwwsss123"
    #生成签名
    hashing=hmac.new(bytes(sk,encoding='utf-8'),bytes(date_new.strip('&'),encoding='utf-8'),hashlib.sha1).hexdigest()
    print(date_new.strip('&'))
    return hashing
data={"name":"wangli","mobile":18200000000,"sn":"","sign":""}
