urllib模块做文本翻译总是报错

左手十字

代码如下：
import urllib.request
import urllib.parse


url_youdao = "http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule&sessionFrom=dict2.index"
URL_ = urllib.request.Request(url_youdao)
data = {}

data['action']= 'FY_BY_CLICKBUTTON'
data['client'] = 'fanyideskweb'
data['doctype'] = 'json'
data['from'] =  'AUTO'
data['i'] =  "i+love+fish"
data['keyfrom'] = 'fanyi.web'
data['salt'] = '1496882870329'
data['sign'] = '7fbb62110ca7370cb949183f5a5c2efc'
data['smartresult'] = 'dict'
data['to'] = 'AUTO'
data['typoResult']=  'true'
data['version'] = '2.1'

data = urllib.parse.urlencode(data).encode('utf-8')
response = urllib.request.urlopen(URL_,data)

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

print(html)


运行后，返回：
=
{"errorCode":50}
