python爬取有道词典json报错，求帮助！

import urllib.request
import urllib.parse
import json
import time
import random
import hashlib

fanyi = input("输入你想翻译的文字：")

url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule'
head = {}
head['User-Agent'] = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36'

u = 'fanyideskweb'
d = fanyi
f = str(int(time.time() * 1000) + random.randint(1, 10))
c = 'rY0D^0\'nM0}g5Mm1z%1G4'

sign = hashlib.md5((u + d + f + c).encode('utf-8')).hexdigest()
data = {}
data['i'] = fanyi
data['from'] = 'AUTO'
data['to'] = 'AUTO'
data['smartresult'] = 'dict'
data['client'] = 'fanyideskweb'
data['salt'] = f  #'15503716490563'
data['sign'] = sign  # 'e1ad61ef4d013802bc9117ee6ee1a053'
data['ts'] = '1550371649056'
data['bv'] = '617939f69fb18f112aa988d6038ae43f'
data['json'] = 'doctype'
data['vison'] = 'version'
data['keyfrom'] = 'fanyi.web'
data['action'] = 'FY_BY_REALTIME'
data['typoResult'] = 'false'

data = urllib.parse.urlencode(data).encode('utf-8')
response = urllib.request.Request(url, data)
response.add_header('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36')
req = urllib.request.urlopen(response)

html = req.read().decode('utf-8')

print(html)
target = json.loads(html)
result = target['translateResult'][0][0]['tgt']

print(result)

运行程序输出的html为：

<!DOCTYPE html>
