又又又出错了，爬取有道翻译出错了，求解

我写的代码如下：
import urllib.request
import urllib.parse

url = 'http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule'

data = {}

data['i'] = 'hello world'
data['from'] = 'AUTO'
data['to'] = 'AUTO'
data['smartresult'] = 'dict'
data['client'] = 'fanyideskweb'
data['salt'] = '15979710202036'
data['sign'] = '98b135fb6a908cd47e75aef09b704a9f'
data['lts'] = '1597971020203'
data['bv'] = '94d04da9bee8870ad9ad8714b54f2bea'
data['doctype'] ='json'
data['version'] = '2.1'
data['keyfrom'] = 'fanyi.web'
data['action'] = 'FY_BY_REALTlME'

data = urllib.parse.urlencode(data).decode('utf-8')

response = urllib.request.urlopen(url,data)

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

print(html)

跟甲鱼老师一步步写的，其中Form Data不一样，于是我就按网页上的写了，但是这个代码点F5运行的话没有任何反应，也没有报错，这是为什么呢？？
我看视频课程上甲鱼老师的可以正常运行啊

有道反爬，要把 url 中的 _o 去掉

而且你代码中的 urllib.parse.urlencode(data).decode('utf-8')改成 urllib.parse.urlencode(data).encode('utf-8')，就行了

import urllib.request
import urllib.parse

url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule'

data = {}

data['i'] = 'hello world'
data['from'] = 'AUTO'
data['to'] = 'AUTO'
data['smartresult'] = 'dict'
data['client'] = 'fanyideskweb'
data['salt'] = '15979710202036'
data['sign'] = '98b135fb6a908cd47e75aef09b704a9f'
data['lts'] = '1597971020203'
data['bv'] = '94d04da9bee8870ad9ad8714b54f2bea'
data['doctype'] ='json'
data['version'] = '2.1'
data['keyfrom'] = 'fanyi.web'
data['action'] = 'FY_BY_REALTlME'

data = urllib.parse.urlencode(data).encode('utf-8')

response = urllib.request.urlopen(url,data)

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

print(html)

运行结果：
                        {"type":"EN2ZH_CN","errorCode":0,"elapsedTime":1,"translateResult":[[{"src":"hello world","tgt":"你好，世界"}]]}

用requests多香~

尽信书则不如无书，小甲鱼的书是几年前的了，代码要不断更新才能适应。
你的代码倒数第4行，那里有错误，我帮你改了一下，decode打错啦，应该是encode。

我改了一下，现在应该可以了，你试一下。
import urllib.request
import urllib.parse

url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule'

data = {}

data['i'] = 'hello world'
data['from'] = 'AUTO'
data['to'] = 'AUTO'
data['smartresult'] = 'dict'
data['client'] = 'fanyideskweb'
data['salt'] = '15979710202036'
data['sign'] = '98b135fb6a908cd47e75aef09b704a9f'
data['lts'] = '1597971020203'
data['bv'] = '94d04da9bee8870ad9ad8714b54f2bea'
data['doctype'] ='json'
data['version'] = '2.1'
data['keyfrom'] = 'fanyi.web'
data['action'] = 'FY_BY_REALTlME'

data = urllib.parse.urlencode(data).encode('utf-8')

response = urllib.request.urlopen(url,data)

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

print(html)
