前言🍭
❤️❤️❤️网络爬虫专栏更新中,各位大佬觉得写得不错,支持一下,感谢了!❤️❤️❤️
前篇简单介绍了什么是网络爬虫及相关概念,这篇开始讲解爬虫中的第一个库——urllib。
urllib🍭
urllib是Python标准库中的一个模块,提供了一些用于处理URL的功能。
使用urllib可以进行URL的解析、发送HTTP请求、文件下载等操作。
1、urllib的基本使用🍉
使用urIlib来获取百度首页的源码🍓
# 使用urI1ib来获取百度首页的源码
import urllib.request
# (1)定义一个urI 赢是你要访问的地址
url = 'http://www.baidu.com/'
# (2)模拟浏微器向服务器发达求 response阿应
response = urllib.request.urlopen(url)
# (3)获取响应中的页面的源码 (content 内容意思)
# read方法 返回的是字节形式的二进制数据
content = response.read()
# (4)打印数据
print(content)
打印结果:
b'
xe7x99xbexe5xbaxa6xe4xb8x80xe4xb8x8bxefxbcx8cxe4xbdxa0xe5xb0xb1xe7x9fxa5xe9
......
可以看到开头字母为b,这代表这返回的是字节形式的二进制数据。我们想要看懂它需要将它转换成字符串,也就是解码(二进制->字符串)。
源码:源码
# 使用urI1ib来获取百度首页的源码
import urllib.request
# (1)定义一个urI 赢是你要访问的地址
url = 'http://www.baidu.com'
# (2)模拟浏微器向服务器发达求 response阿应
response = urllib.request.urlopen(url)
# (3)获取响应中的页面的源码 (content 内容意思)
# read方法 返回的是字节形式的二进制数据 我们使用decode进行主动解码,将其转换成字符串
content = response.read().decode("utf-8")
# (4)打印数据
print(content)
打印结果:
2、一个类型六个方法🍉
一个类型🍓
为什么要讲一个类型呢?因为后面要讲的一个库叫request库,request库也有相对应的响应,但是它的类型不一样,为了进行一个对比,才进行这样的一个讲解。
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# 一个类型六个方法
print(type(response))
类型打印:
从上面我们可以知道response的数据类型是HttpResponse,我们需要去记住。
六个方法🍓
Ⅰ、read方法
read方法是按照一个字节一个字节的去读
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# 按照一个字节一个字节的去读
content = response.read()
print(content)
read方法按字节读
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# read方法按字节读
content = response.read(5)
print(content)
打印结果:
b'
Ⅱ、readline方法按行读
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# readline方法按行读
content = response.readline()
print(content)
打印结果:
b'

Ⅲ、readlines按行读直到读完
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# readlines按行读直到读完
content = response.readlines()
print(content)
Ⅳ、getcode获取状态码
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# getcode获取状态码
print(response.getcode())
打印结果:
200
常见状态码
在HTTP协议中,常见的状态码用于表示服务器对请求的处理结果。以下是一些常见的状态码及其含义:
- 200 OK:请求成功,服务器成功处理了请求并返回了所需的数据。
- 301 Moved Permanently:永久重定向,请求的资源已永久移动到新的URL。
- 302 Found:临时重定向,请求的资源暂时移动到了新的URL。
- 400 Bad Request:请求无效,服务器无法理解或处理请求。
- 401 Unauthorized:未授权,请求需要身份验证。
- 403 Forbidden:禁止访问,服务器拒绝请求访问资源。
- 404 Not Found:未找到,服务器无法找到请求的资源。
- 500 Internal Server Error:服务器内部错误,服务器在处理请求过程中发生了错误。
- 502 Bad Gateway:错误的网关,作为代理或网关的服务器从上游服务器接收到无效的响应。
- 503 Service Unavailable:服务不可用,服务器暂时无法处理请求,通常是由于过载或维护。
这只是一些常见的状态码,HTTP协议中还有更多的状态码,每个状态码都有特定的含义和用途。在开发或使用HTTP请求时,了解常见的状态码可以帮助你更好地理解服务器对请求的响应。
Ⅴ、geturl获取url地址
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# getcode获取状态码
print(response.geturl())
打印结果:
http://www.baidu.com
Ⅵ、getheaders方法获取headers(一个状态信息)
import urllib.request
url = "http://www.baidu.com"
# 模拟浏览器向服务器发送请求
response = urllib.request.urlopen(url)
# getcode获取状态码
print(response.getheaders())
打印信息:

3、下载🍉
我们可以通过爬虫(urllib.request.urlretrieve())将网页、图片、视频下载下来。
下载网页🍓
下载百度的网页
import urllib.request
# 下载网页
url_page = "http://www,.baidu, com"
# urI代表的是下载的路径 filename文件的名字# 在python中 可以变量的名字 也可以直接写值
urllib.request.urlretrieve(url_page, 'baidu.html')
下载好了之后浏览器打开:
下载图片🍓
import urllib.request
# 下载图片
url_img="https://profile-avatar.csdnimg.cn/82351d3cb9754fda97cb85258d7e74a0_m0_63951142.jpg!1"
urllib.request.urlretrieve(url_img, filename="tx.jpg")
把我的头像链接输入,下载下来:
下载视频🍓
再找到里面的src
这就是我们的视频地址
import urllib.request
# 下载网页
# url_page = "http://www.baidu.com"
# # urI代表的是下载的路径 filename文件的名字# 在python中 可以变量的名字 也可以直接写值
# urllib.request.urlretrieve(url_page, 'baidu.html')
