大家好，我是皮皮。
一、前言
前几天在Python白银交流群【斌】问了一个Python网络爬虫的问题，提问截图如下：
报错截图如下：
粉丝需要的数据如下：
二、实现过程
有道翻译之前有做过很多，确实适合练手，主要是需要找到对应的请求。这里【dcpeng】结合粉丝的代码，然后给了一份正确的代码，如下所示：
import requests
headers = {
"Accept": "application/json, text/javascript, */*; q=0.01",
"Accept-Language": "zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6",
"Connection": "keep-alive",
"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",
"Origin": "https://fanyi.youdao.com",
"Referer": "https://fanyi.youdao.com/",
"Sec-Fetch-Dest": "empty",
"Sec-Fetch-Mode": "cors",
"Sec-Fetch-Site": "same-origin",
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.102 Safari/537.36 Edg/104.0.1293.70",
"X-Requested-With": "XMLHttpRequest",
"sec-ch-ua": "\"Chromium\";v=\"104\", \" Not A;Brand\";v=\"99\", \"Microsoft Edge\";v=\"104\"",
"sec-ch-ua-mobile": "?0",
"sec-ch-ua-platform": "\"Windows\""
}
cookies = {
"OUTFOX_SEARCH_USER_ID": "[email protected]",
"OUTFOX_SEARCH_USER_ID_NCOO": "242914410.9668874",
"P_INFO": "pdcfighting",
"_ga": "GA1.2.1404336446.1645147264",
"ANTICSRF": "cleared",
"NTES_OSESS": "cleared",
"S_OINFO": "",
"___rl__test__cookies": "1662539503369"
}
url = "https://fanyi.youdao.com/translate_o"
params = {
"smartresult": "rule"
}
data = {
"i": "dog",
"from": "AUTO",
"to": "AUTO",
"smartresult": "dict",
"client": "fanyideskweb",
"salt": "16625395033719",
"sign": "2a0056b7249263308d07a3fce52c065c",
"lts": "1662539503371",
"bv": "6f1d3ad76bcde34b6b6745e8ab9dc20a",
"doctype": "json",
"version": "2.1",
"keyfrom": "fanyi.web",
"action": "FY_BY_REALTlME"
}
response = requests.post(url, headers=headers, cookies=cookies, params=params, data=data)
print(response.json())
print(response)
运行之后，便可得到对应的结果了，如下图所示：
后来发现是构造参数少传了，难怪没获取到信息！
后来粉丝发现了最终问题所在，虽然没看懂，但是只要解决问题了就好！
三、总结
大家好，我是皮皮。这篇文章主要盘点了一个Python网络爬虫的问题，文中针对该问题，使用正则表达式匹配出想要的结果，并给出了具体的解析和代码实现，帮助粉丝顺利解决了问题。
