如何通过python-3.6在网站html中搜索？
我有很多礼物，我需要创建检查器，这将检查礼物是否有效-->它将在html中搜索一些单词。我在寻找“礼物代码无效” 当我试图通过urllib或请求读取html时，它只会加载html的一小部分。我是初学者，所以我可能做错了什么 我的代码是：如何通过python-3.6在网站html中搜索？,python,html,search,python-requests,python-3.6,Python,Html,Search,Python Requests,Python 3.6,我有很多礼物，我需要创建检查器，这将检查礼物是否有效-->它将在html中搜索一些单词。我在寻找“礼物代码无效” 当我试图通过urllib或请求读取html时，它只会加载html的一小部分。我是初学者，所以我可能做错了什么 我的代码是： import requests link = "https://discord.gift/o2uzOR7YE3CoBpGq" r = requests.get(link) print(r.text) 输出为： <!DOCTYPE html> <

您要查找的“礼物代码无效”可能是由js呈现的。 请求不会呈现js输出，这就是您无法找到它的原因 如果您使用的是Python3.6，请尝试使用html请求以js输出呈现网页 更新示例：
from requests_html import HTMLSession
link = 'https://discord.gift/o2uzOR7YE3CoBpGq'
targetString = "Gift Code Invalid"
session = HTMLSession()
r = session.get(link)
print("Before render is call: ", targetString in r.html.text)
# sleep has to be implemented after initial the render to get the proper response
r.html.render(wait=2, sleep=1)
print("After render is call: ", targetString in r.html.text)
Before render is call: False
After render is call: True
Process finished with exit code 0
该网站在后台发送一个ajax请求，并检查礼品代码的有效性。它发送一个json响应，以指示礼品代码是否有效。然后用javascript填充数据 获得所需结果的最简单方法是模拟ajax请求并获取消息。您可以不使用selenium、requests html或任何其他javascript呈现机制来实现这一点，并且仍然可以获得所需的输出—以检查礼物是否有效
import requests
gift_code='o2uzOR7YE3CoBpGq' #gift code here
link = f"https://discordapp.com/api/v6/entitlements/gift-codes/{gift_code}?with_application=true&with_subscription_plan=true"
r = requests.get(link)
print(r.json()['message'])
Unknown Gift Code
