我正在尝试使用 python 抓取特定法语单词的例句，但我返回 python 的页面似乎没有任何结果。

我已经检查了搜索框和搜索按钮的元素并将它们作为参数包含在内。也许我错过了什么？

http://www.online-languages.info/french/examples.php 

import requests
from bs4 import BeautifulSoup

word = 'manger'
url='http://www.online-languages.info/french/examples.php'
params ={'word':word,'go':''}

response=requests.post(url, data=params)
soup = BeautifulSoup(response.text, 'html5lib')

最佳答案

这对我有用。请注意，我使用了 GET 方法以及该页面上实际表单中引用的 URI。

import requests

word = 'manger'
url ='http://www.dicts.info/examples.php'
headers = {'Referer': 'http://www.dicts.info/examples.php?disa=1&lang2=french&word=bon&go=Search'}
params = {'word':word,'disa':'1','lang2':'french'}

response = requests.get(url, params=params, headers=headers)
print(response.text)

更新

PHP 页面似乎会进行检查，以确保随请求发送了适当的引用 header 。因此，请添加一个，就像我上面所做的那样(编辑了原始内容)。
