How to realize the mutual conversion between CURL and python requests in python

curl and Python requests are both powerful tools for sending HTTP requests. While curl is a command-line tool that lets you send requests directly from the terminal, Python's requests library provides a more programmatic way to send requests from Python code.

Convert curl to Python requests

The basic syntax of the curl command is as follows:

curl [OPTIONS] URL

When converting the curl command to Python requests, we need to convert the options and URL is Python code.

This is a sample curl POST command:

curl -X POST https://example.com/api/v1/users \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY' \
    -d '{"username": "john_doe", "email": "john_doe@example.com"}'

To convert this curl command into a Python request, we can write the following code:

import requests

url = 'https://example.com/api/v1/users'
headers = {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
}
data = {
    'username': 'john_doe',
    'email': 'john_doe@example.com'
}

response = requests.post(url, headers=headers, json=data)

print(response.status_code)
print(response.json())

In this example, we Use the requests.post() method to send a POST request to the URL https://example.com/api/v1/users with the JSON payload {"username": "john_doe", "email": "john_doe@example.com" ”}`. We also include Content-Type and Authorization headers.

Convert Python requests to curl

Converting Python request code to curl commands is a bit tricky because there is no direct equivalent of the requests library on the command line. However, we can pass data to the curl command using the --data or -d option and set the header using the -H option.

This is a sample Python GET request script:

import requests

url = 'https://example.com/api/v1/users'
headers = {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
}
params = {
    'username': 'john_doe',
    'sort': 'name',
    'order': 'asc'
}

response = requests.get(url, headers=headers, params=params)

print(response.status_code)
print(response.json())

To convert this Python request code into a curl command, we can use the following command:

curl -X GET 'https://example.com/api/v1/users?username=john_doe&sort=name&order=asc' \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer YOUR_API_KEY'

In this example , we use the -X GET option to specify that we send a GET request and pass the URL and query parameters as strings. We also include Content-Type and Authorization headers.
