What is the difference between proxy http and https?

As we all know, there are two common communication protocols in the online world, namely http and https. their existence facilitates our web browsing and data transfer, but do you know what are the differences between them? In this article, we will find out and explore the differences between proxy http and https.

1. http - a ipipgo no-frills transmission method

First of all, let's understand the http protocol. http is a hypertext transfer protocol that is used for communication between a client (browser) and a server. For http, the data is not encrypted when it is transmitted, just like the windows in your home, leaving the data open to each other.

To describe http more graphically, we can look at it this way: suppose you have a phone conversation with a friend, and an eavesdropper can not only listen in on what you are saying, but also spy on your expressions, gestures and even the frequency of your yawns. This is because the http protocol transmits all the data to the receiver completely naked, as in naked and unreserved.

2.https - eavesdropper's nightmare

Unlike http, the biggest draw of the https protocol (also known as http over SSL) is data encryption. It uses the SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocol to protect the secure transmission of data. It's like installing a security door in your home, ensuring that you and your friends have privacy when talking on the phone, and it's hard for eavesdroppers to pry into your exchanges.

The relationship between http and https is like that of an unhappy couple. http has been living a happy and unprotected life, while https adds many security layers on top of http to protect the authenticity and integrity of the data.

3. proxy http and proxy https - the existence of arbitration

Sometimes we use a proxy server in order to protect the true identity of the client and the server. A proxy server sits between the client and the server and acts as a translator, forwarding requests and responses from both sides.

The main difference between proxy http and proxy https is the encryption of data. When we use proxy http, the communication between the client and the proxy server is still transmitted in plaintext, while when we use proxy https, the communication between the client and the proxy server will be encrypted. In short, proxy https is more secure and reliable than proxy http.

The following is a sample code to implement proxy http and proxy https using Python language:

import requests

# proxy http
url_http = 'http://www.example.com'
proxy_http = {'http': 'http://127.0.0.1:8080'}

response_http = requests.get(url_http, proxies=proxy_http)
print(response_http.text)

# proxy https
url_https = 'https://www.example.com'
proxy_https = {'https': 'https://127.0.0.1:8080'}

response_https = requests.get(url_https, proxies=proxy_https)
print(response_https.text)

In the above code, we use the requests library to send http and https requests and specify the proxy server address by setting the proxies parameter. The proxy address in the code example is the local port 8080, you need to modify it according to the actual situation.

Through the comparison of the above code, it is not difficult to find that the proxy http and proxy https in the use of the way is very similar, only in the actual transmission process of data security differences. Therefore, when choosing a proxy, we need to decide which one to use according to the actual needs and security requirements.

summarize

In this article, we explore the difference between proxy http and proxy https. http is a data transfer protocol without encryption, while https adds encryption protection on top of http for more secure and reliable data transfer. Through the sample code, we further understand the usage and differences between proxy http and proxy https. Whether we choose http or https, we should make a suitable choice according to the actual needs and circumstances to ensure the security and reliability of data.
