保障数据安全最好的方法，当然是加密了。无法解析内容，自然无法伪造，篡改。 可是使用https证书需要收费的。有其它方法么？ 有的。 消息哈希认证(hmac)。
1. 当访问接口时, 将参数按key值排序，组成key1=value1&key2=value2&....&secret_key=... 2. 然后对上面结果做md5，生成签名sign 3. 将sign放到加入请求的参数
密钥是被访问者提供了，它也有访问者的secret_key. 1.根据app_id查到secret_key 2.处理请求参数，按规则组成key1=value1&key2=value2....&secret_key=... 3.对上一步结果做md5,生成sign。比较两个sign，相等则身份验证通过
import md5
app_id=123
secret_key="xxxxxxxx"
request_param = dict(
key1="value1",
key2="value2",
key3="value3"
)
def sign():
params = ["%s=%s" % (key, value) for key, value in sorted(request_param.items(), key=lambda item: item[0])]
params.append("secret_key=%s" % secret_key)
str_param = "&".join(params)
print str_param
md = md5.md5()
md.update(str_param)
return md.hexdigest()
