各人好，我是皮皮。
一、前言
前几天在Python白银互换群【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许多，确实适当练手，主要是需要找到对应的哀求。这里【dcpeng】联合粉丝的代码，然后给了一份准确的代码，如下所示：
import requestsheaders = { "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": "-835551069@223.104.228.2", "OUTFOX_SEARCH_USER_ID_NCOO": "242914410.9668874", " _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：
厥后发现是构造参数少传了，难怪没获取到信息！
厥后粉丝发现了终极问题所在，固然没看懂，但是只要办理问题了就好！
三、总结
各人好，我是皮皮。这篇文章主要盘货了一个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，并给出了详细的分析和代码实现，资助粉丝顺遂办理了问题。
末了感谢粉丝【斌】提问，感谢【dcpeng】、【猫药师Kelly】给出的思绪和代码分析，感谢【Python狗】等人参加学习互换。 |
