python访问有道翻译问题

鬼少

有如下一段代码，通过python访问有道翻译， （由于我没有发送带url 权限的帖子，这里省略的url网址， 可以认为网址是正确的。）
import urllib.request
import urllib.parse
import json

content = input("请输入需要翻译的内容:")

ur l = '......'
data = {}
data['type'] =  'AUTO'
data['i'] = content
data['doctype']= 'json'
data['xmlversion']= '1.6'
data['keyfrom']= 'fanyi.web'
data['ue'] =  'UTF-8'
data['typoResult'] =  'true'
#data['smartresult'] =  'dict'
data = urllib.parse.urlencode(data).encode('utf-8')
response = urllib.request.urlopen(url, data)
html = response.read().decode('utf-8')


target = json.loads(html)
print("翻译结果: %s" % (target['translateResult'][0][0]['tgt']))

当执行上述代码时， 却出现如下错误：
Traceback (most recent call last):
  File "D:/program/python_code/translate.py", line 23, in <module>
    target = json.loads(html)
  File "D:\program\Python\Python312\Lib\json\__init__.py", line 346, in loads
    return _default_decoder.decode(s)
  File "D:\program\Python\Python312\Lib\json\decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "D:\program\Python\Python312\Lib\json\decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

哪位高手能帮忙给看看， 谢谢
