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 base64import urllib.parseimport hmacfrom hashlib import sha1import requestsimport uuidimport timeimport hmac,sslALIYUN_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_contextexcept AttributeError:    # Legacy Python that doesn't verify HTTPS certificates by default    passelse:    # 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']=1.0D['AccessKeyId']=ALIYUN_ACCESS_KEY_IDD['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idD['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：
