Understanding Proxies with Python's 'Requests' Module
Question:
The documentation for the 'Requests' module in Python mentions a 'proxies' variable, but it doesn't provide clear details on its expected content. How should this variable be structured?
Answer:
To use the 'proxies' variable effectively, it's essential to understand its syntax and purpose. The 'proxies' variable accepts a dictionary as its value. This dictionary maps different protocols (e.g., HTTP, HTTPS, FTP) to their respective proxy URLs. Here's an example:
http_proxy = "http://10.10.1.10:3128" https_proxy = "https://10.10.1.11:1080" ftp_proxy = "ftp://10.10.1.10:3128" proxies = { "http": http_proxy, "https": https_proxy, "ftp": ftp_proxy, } r = requests.get(url, headers=headers, proxies=proxies)
By specifying different proxy URLs for each protocol, you can customize your proxying strategy. Alternatively, you can set these proxies as environment variables:
Linux:
export HTTP_PROXY=10.10.1.10:3128 export HTTPS_PROXY=10.10.1.11:1080 export FTP_PROXY=10.10.1.10:3128
Windows:
set http_proxy=10.10.1.10:3128 set https_proxy=10.10.1.11:1080 set ftp_proxy=10.10.1.10:3128
Note that the 'proxies' variable can take two values per protocol mapping. However, it's not necessary to convert them to any specific type before placing them in the dictionary.
The above is the detailed content of How to Structure the `proxies` Variable in Python\'s `requests` Module?. For more information, please follow other related articles on the PHP Chinese website!

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti

Serialization and deserialization of Python objects are key aspects of any non-trivial program. If you save something to a Python file, you do object serialization and deserialization if you read the configuration file, or if you respond to an HTTP request. In a sense, serialization and deserialization are the most boring things in the world. Who cares about all these formats and protocols? You want to persist or stream some Python objects and retrieve them in full at a later time. This is a great way to see the world on a conceptual level. However, on a practical level, the serialization scheme, format or protocol you choose may determine the speed, security, freedom of maintenance status, and other aspects of the program

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),
