Python3.x调用阿里云短信api

最近制作注册系统需要进行一个短信验证的功能，决定使用阿里云通信的短信服务，可是坑爹的问题就来了，阿里提供的SDK不支持Python3.x，遂只能通过其HTTP协议方式拼接url 官方文档

因为涉及到url编码问题，博主之前全是encode('utf-8')之后再转string再处理replace('\\x','%')真是太幸酸，后面知道可以使用urllib中的request包的quote函数方方便便的url编码问题，其他的就是跟着协议来了。贴上实现代码：

from urllib import request
import uuid
import time
import hashlib
import hmac
import base64
import os

def log(text):
    def decorator(function):
        def wrapper(*args,**kwargs):
            print('Pid:%s running %s [function:%s] at %s'%(os.getpid(),text,function.__name__,time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())))
            return function(*args,**kwargs)
        return wrapper
    return decorator

class MsgUrlBulid:
    def __init__(self,Dic,SercetID=None):
        self.HttpMethod='GET'
        self._infor=Dic
        if SercetID==None:
            raise ValueError('SercetID must input!')
        self._SercetID=SercetID
        print('api information write compelet!')
    @staticmethod
    def Encode(x):
        x=request.quote(x,safe='')
        x = x.replace("+", "%20").replace("*", "%2A").replace("%7E", "~")
        return x
    @log('build sorted dictionary')
    def _BulidQuery(self):
        if self._infor==None:
            raise ValueError('please init first')
        lst=sorted(self._infor)
        tmpLst=[]
        for k in lst:
            v=self._infor[k]
            para='%s=%s'%(self.Encode(k),self.Encode(v))
            tmpLst.append(para)
        return '&'.join(tmpLst)
    @log('build string to sign')
    def _Signtosign(self,x):
        return self.HttpMethod+'&'+self.Encode('/')+'&'+self.Encode(x)

    @log('create a sign')
    def _CreateSign(self,x):
        Sha1=hmac.new((self._SercetID+'&').encode('utf-8'),x.encode('utf-8'),hashlib.sha1).digest()
        Sign=base64.b64encode(Sha1)
        return self.Encode(Sign)
    @log('reset the informaton of api')
    def resetinfor(self,Dic):
        self._infor=Dic
    @log('start build request')
    def UrlBulid(self):
        Basestr=self._BulidQuery()
        tmp=self._Signtosign(Basestr)
        x=self._CreateSign(tmp)
        return 'http://dysmsapi.aliyuncs.com/?Signature=%s&%s'%(x,Basestr)

使用方法 把相关数据替换一下就可以了：

if __name__=='__main__':
    form={}
    form["SignatureMethod"] = "HMAC-SHA1"
    form["SignatureNonce"] = str(uuid.uuid1())
    form["AccessKeyId"] = 'your AcessKeyId'
    form["SignatureVersion"] = "1.0"
    form['Timestamp'] = time.strftime("%Y-%m-%dT%H:%M:%SZ", time.gmtime())

    form['Action'] = "SendSms"
    form['Version'] = "2017-05-25"
    form['RegionId'] = "cn-hangzhou"
    form['SignName'] = "your signname"#签名
    form['TemplateParam'] = '{"code":"xxxx"}'#模板替换部分
    form['PhoneNumbers'] = "target telphone number"#接受信息的号码
    form['TemplateCode'] = "your templatecode"#模板号
    x=MsgUrlBulid(form,'your sercetid')#
    print(x.UrlBulid())

需要重置信息调用x.resetinfor(form)就好

运行结果：
