使用Python请求时，DuckDuckGo返回418
我正在编写一个脚本，在打开firefox时，它会找到给定术语的第一个duckduckgo结果。使用Python请求时，DuckDuckGo返回418,python,python-requests,Python,Python Requests,我正在编写一个脚本，在打开firefox时，它会找到给定术语的第一个duckduckgo结果。 我知道。它非常有用 但是当从我的浏览器复制url并使用python请求它时： url = "https://duckduckgo.com/?t=ffab&q=python+request+duckduckgo&ia=software" req = r.get(url) Duckduckgo返回418 发生了什么事 duckduckgo是否意识到我在做自动请求并决定
我知道。它非常有用 但是当从我的浏览器复制url并使用python请求它时：
url = "https://duckduckgo.com/?t=ffab&q=python+request+duckduckgo&ia=software"
req = r.get(url)
duckduckgo是否意识到我在做自动请求并决定变成一个茶壶？
如果是这样的话，我该如何避免呢
我也知道python有一个duckduckgo api，但我做这个项目是为了开始使用
请求和beautifulsoup
虽然这可能不是一个确切的问题，但duckduckgo绝对不适合机器人和删除其搜索内容。看看他们的照片。这个来自网站的文件告诉你如何对待爬虫和用户的网站——哪些页面允许爬网，哪些页面不能爬网
从外观上看，您尝试爬网的所有内容都是不允许的。你很可能会得到茶壶作为回应，因为这是他们在未经允许的情况下对爬虫的回应
如果您试图了解请求
，最好避免使用搜索引擎。据我所知，大多数常见的爬虫都是不允许外部爬虫的。虽然这可能不是一个确切的问题，但duckduckgo绝对不适合机器人和抓取其搜索内容。看看他们的照片。这个来自网站的文件告诉你如何对待爬虫和用户的网站——哪些页面允许爬网，哪些页面不能爬网

，最好避免使用搜索引擎。据我所知，大多数常见的方法都不允许外部爬虫。您需要添加一个“用户代理”标题，即使是一个简单的标题：

import requests

response = requests.get(url, headers={'user-agent': 'my-app/0.0.1'})
response.raise_for_status() # throw an exception if not a 200 return code

您必须了解HTML可能包含JavaScript，该JavaScript在页面加载后执行，从而修改页面内容。因此，您在浏览器中看到的内容可能与通过请求加载的HTML中看到的内容不一致。如果是这种情况，您可能需要一个不同的工具，例如selenium
来驱动实际的web浏览器。我会将此添加到我现有的答案中，因为我会超过最大字符长度。在某种程度上，这是与我的第一个答案相关的第二个答案，其中我指出，请求
返回的HTML可能无法反映您在浏览器中看到的内容，因为加载和执行的JavaScript代码修改了页面内容。在这种情况下，您需要使用工具，如selenium
：
from selenium import webdriver
import time
driver = webdriver.Chrome()
driver.get("https://duckduckgo.com/?t=ffab&q=python+request+duckduckgo&ia=software")
time.sleep(3) # give page a chance to fully load
print(driver.page_source)
driver.quit()
