最近有一個專案需要呼叫阿里雲小蜜，我就拿python呼叫了一下，然後在官網居然沒有找到很好的sample code。就只能自己硬著頭皮寫一下啦

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"

# 解決 訪問ssl網站證書的問題
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請求方法
    bs = ALIYUN_ACCESS_KEY_SECRET + '&'
    bs = bytes(bs, encoding='utf8')
    stringToSign = bytes(stringToSign, encoding='utf8')
    h = hmac.new(bs, stringToSign, sha1)
    # 進行編碼
    signature = base64.b64encode(h.digest()).strip()
    return signature

D['Action']="Chat"
D['InstanceId']="your instance id" #你阿里雲的機器人例項id
D['Utterance']="電腦黑屏了怎麼辦"
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)

 

執行成功了，我的輸出為：
