如何用PYTHON调用云小蜜

最近有一个项目需要调用阿里云小蜜，我就拿python调用了一下，然后在官网居然没有找到很好的sample code。就只能自己硬着头皮写一下啦

import base64

import urllib.parse

import hmac

from hashlib import sha1

import requests

import uuid

import time

import hmac,ssl

ALIYUN_ACCESS_KEY_ID="your id"

ALIYUN_ACCESS_KEY_SECRET="your secret"

 

# 解决 访问ssl网站证书的问题

try:

    _create_unverified_https_context = ssl._create_unverified_context

except AttributeError:

    # Legacy Python that doesn't verify HTTPS certificates by default

    pass

else:

    # Handle target environment that doesn't support HTTPS verification

    ssl._create_default_https_context = _create_unverified_https_context

 

D = {

    'Format':'JSON',

    'Version':'2017-10-11',

    'SignatureMethod':'HMAC-SHA1'

    }

timestamp = time.strftime("%Y-%m-%dT%H:%M:%SZ", time.gmtime())

D['SignatureNonce']=str(uuid.uuid1())

D['SignatureVersion']=1.0

D['AccessKeyId']=ALIYUN_ACCESS_KEY_ID

D['Timestamp']=timestamp

 

 

def percent_encode(encodeStr):

    encodeStr = str(encodeStr)

    res = urllib.parse.quote(encodeStr)

    res = res.replace('+', '%20')

    res = res.replace('*', '%2A')

    res = res.replace('%7E', '~')

    return res

 

def sign(parameters):

    sortedParameters = sorted(parameters.items(), key=lambda parameters: parameters[0])

    print(sortedParameters)

    canonicalizedQueryString = ''

    for (k, v) in sortedParameters:

        canonicalizedQueryString += '&' + percent_encode(k) + '=' + percent_encode(v)

    stringToSign = 'GET&%2F&' + percent_encode(canonicalizedQueryString[1:])  # 使用get请求方法

    bs = ALIYUN_ACCESS_KEY_SECRET + '&'

    bs = bytes(bs, encoding='utf8')

    stringToSign = bytes(stringToSign, encoding='utf8')

    h = hmac.new(bs, stringToSign, sha1)

    # 进行编码

    signature = base64.b64encode(h.digest()).strip()

    return signature

 

D['Action']="Chat"

D['InstanceId']="your instance id" #你阿里云的机器人实例id

D['Utterance']="电脑黑屏了怎么办"

D['Signature'] = sign(D)

 

 

sortedParameters = sorted(D.items(), key=lambda D: D[0])

# print(D["Signature"])

# print(sortedParameters)

 

url = 'https://chatbot.cn-shanghai.aliyuncs.com/?' + urllib.parse.urlencode(sortedParameters)

print(url)

r = requests.get(url)

print(r.text)

运行成功了，我的输出为：
