在学习小甲鱼的零基础入门python里的爬虫第二节，跟着小甲鱼练习了一下爬取有道翻译，程序如下：
import urllib.request
import urllib.parse

url = 'https://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule'
data = {}
data['from'] = 'AUTO'
data['to'] = 'AUTO'
data['i'] = content
data['smartresult'] = 'dict'
data['client'] = 'fanyideskweb'
data['salt'] = '16479194564289'
data['sign'] = '1dd5674882aee0c529d9bb615fcb72c9'
data['lts'] = '1647919456428'
data['bv'] = '097b265c57844c587e0fd5b8ecb30a24'
data['doctype'] = 'json'
data['version'] = '2.1'
data['keyfrom'] = 'fanyi.web'
data['action'] = 'FY_BY_CLICKBUTTION'
data = urllib.parse.urlencode(data).encode('utf-8')

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

print(html)

但程序报错为：b'{"errorCode":50}'
百度了一下，说是有道加入了反爬机制，但还是求大神解答一下是什么原因

是因为你的接口不对，你的代码应该改成这样：

import urllib.request

import urllib.parse

url = 'http://fanyi.youdao.com/translate'

data = {}

data['from'] = 'AUTO'

data['to'] = 'AUTO'

data['i'] = content

data['smartresult'] = 'dict'

data['client'] = 'fanyideskweb'

data['salt'] = '16479194564289'

data['sign'] = '1dd5674882aee0c529d9bb615fcb72c9'

data['lts'] = '1647919456428'

data['bv'] = '097b265c57844c587e0fd5b8ecb30a24'

data['doctype'] = 'json'

data['version'] = '2.1'

data['keyfrom'] = 'fanyi.web'

data['action'] = 'FY_BY_CLICKBUTTION'

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

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

html = response.read()

print(html)
