HomeBackend DevelopmentPython TutorialPython中http请求方法库汇总

最近在使用python做接口测试,发现python中http请求方法有许多种,今天抽点时间把相关内容整理,分享给大家,具体内容如下所示:

一、python自带库----urllib2

python自带库urllib2使用的比较多,简单使用如下:

import urllib2
response = urllib2.urlopen('http://localhost:8080/jenkins/api/json?pretty=true')
print response.read() 

简单的get请求

import urllib2
import urllib
post_data = urllib.urlencode({})
response = urllib2.urlopen('http://localhost:8080/, post_data)
print response.read()
print response.getheaders() 

这就是最简单的urllib2发送post例子。代码比较多

二、python自带库--httplib

httplib是一个相对底层的http请求模块,urlib就是基于httplib封装的。简单使用如下:

import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("GET", "/index.html")
r1 = conn.getresponse()
print r1.status, r1.reason
data1 = r1.read()
conn.request("GET", "/parrot.spam")
r2 = conn.getresponse()
data2 = r2.read()
conn.close() 

简单的get请求

我们再来看post请求

import httplib, urllib
params = urllib.urlencode({'@number': 12524, '@type': 'issue', '@action': 'show'})
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
conn = httplib.HTTPConnection("bugs.python.org")
conn.request("POST", "", params, headers)
response = conn.getresponse()
data = response.read()
print data
conn.close() 

是不是觉得太复杂了。每次写还得再翻文档,看看第三种吧

三、第三方库--requests

发请get请求超级简单:

print requests.get('http://localhost:8080).text 

就一句话,再来看看post请求

payload = {'key1': 'value1', 'key2': 'value2'}
r = requests.post("http://httpbin.org/post", data=payload)
print r.text 

也很简单。

再看看如果要认证:

url = 'http://localhost:8080'
r = requests.post(url, data={}, auth=HTTPBasicAuth('admin', 'admin'))
print r.status_code
print r.headers
print r.reason 

是不是比urllib2更简单多了吧,且requests自带json解析。这点非常棒

python中的http请求

import urllib
params = urllib.urlencode({key:value,key:value})
resultHtml = urllib.urlopen('[API or 网址]',params)
result = resultHtml.read()
print result

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python: compiler or Interpreter?Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
