3 Easy Steps To Make a GET Request With cURL – OrcaCore

In this guide, we want to teach you How To Make a GET Request With cURL. As you must know cURL is a Linux command line utility that is used to transfer data over the Internet. You can easily use the cURL command to request data and receive your desired information. Here on the Orcacore website, you will learn to make a get request by using the curl command. Understanding how to Make a GET Request With cURL is a valuable skill for any developer or system administrator.

To Make a GET Request With cURL, you must have access to your server as a root or non-root user with sudo privileges. Then, follow the steps below to see how you can make a get request.

The curl command line tool is installed on the Linux distros by default.

1. Making an HTTP Get Request with cURL

You can request data from a web server by using the HTTP Get Request. HTTP GET requests cannot send data to the server in the body of a GET message or change the server’s state. But you can still pass data to the server in URL parameters.

The format to make a get request is like the following:

curl -X GET <URL>

You can replace the URL with your target server and make a get request for it. For example:

curl -X GET https://google.com

The -X GET option specifies that the HTTP method is GET. When the command runs, curl sends a GET request to the server specified in the URL and waits for the server’s response.

If the server responds with a successful status code, the curl displays the response body in the terminal.

Or you can use the following syntax instead:

curl https://google.com

This command will show you the same results as the above command.

At this point, you can only request a for only HTTP headers instead of getting the body of the request. To do this, you can use the -I option in the curl command. For example:

curl -I https://google.com

2. Making a JSON Request with cURL

You can receive your data in the format of JSON. To do this, you can use the -H “Accept: application/json” option in the curl command. For example:

curl https://google.com -H "Accept: application/json"

You can easily Make a GET Request With cURL from a server.

Alternative Solutions for Making GET Requests

While cURL is a powerful and widely used tool, there are other methods to perform GET requests, especially when working within a specific programming language or environment. Let’s explore two alternative approaches: using Python’s requests library and using wget.

1. Using Python’s requests Library

The requests library in Python provides a higher-level, more human-friendly interface for making HTTP requests. It simplifies tasks like handling headers, authentication, and response parsing. To use requests, you’ll first need to install it:

pip install requests

Then, you can make a GET request like this:

import requests

url = "https://google.com"

try:
    response = requests.get(url)

    # Check if the request was successful
    response.raise_for_status()  # Raises HTTPError for bad responses (4xx or 5xx)

    # Print the response content
    print(response.text)

    # Print the headers
    print(response.headers)

except requests.exceptions.RequestException as e:
    print(f"An error occurred: {e}")

Explanation:

• import requests: Imports the requests library.
• url = "https://google.com": Defines the URL you want to request.
• response = requests.get(url): Sends a GET request to the specified URL and stores the response in the response variable.
• response.raise_for_status(): This is an important step for error handling. It checks the HTTP status code of the response. If the status code indicates an error (e.g., 404 Not Found, 500 Internal Server Error), this method will raise an HTTPError exception, which can be caught in the except block.
• print(response.text): Prints the HTML content of the response.
• print(response.headers): Prints the HTTP headers of the response.
• except requests.exceptions.RequestException as e: This block catches any exceptions that occur during the request process, such as network errors, timeout errors, or invalid URLs. This allows for graceful error handling.

Advantages of using requests:

• Simpler syntax: The requests library provides a more intuitive and readable API compared to cURL‘s command-line syntax.
• Automatic encoding/decoding: requests automatically handles encoding and decoding of request and response data, simplifying working with different character sets.
• Built-in JSON support: requests has built-in methods for encoding and decoding JSON data, making it easier to work with APIs that return JSON responses. You can directly access the JSON data with response.json().
• Integration with Python code: Using requests allows you to seamlessly integrate HTTP requests into your Python scripts and applications.

2. Using wget

wget is another command-line utility, similar to cURL, used for retrieving content from web servers. While primarily designed for downloading files, it can also be used to perform simple GET requests.

To make a GET request using wget, simply use the following command:

wget https://google.com

This command will download the HTML content of https://google.com and save it as a file named index.html in the current directory. If a file with that name already exists, it will be saved as index.html.1, index.html.2, and so on.

To output the content directly to the console instead of saving it to a file, you can use the -q (quiet) and -O (output document) options:

wget -q -O - https://google.com

Explanation:

• wget: The command to invoke the wget utility.
• -q: Specifies the quiet mode, which suppresses most of the output messages.
• -O -: Specifies that the output should be written to standard output (stdout), which is typically the console.
• https://google.com: The URL you want to retrieve.

Advantages of using wget:

• Simple for basic downloads: wget is straightforward for downloading files directly from the command line.
• Widely available: Like cURL, wget is often pre-installed on many Linux distributions.
• Supports recursive downloads: wget can recursively download files from a website, following links to other pages.

Disadvantages compared to cURL and requests:

• Less flexibility: wget offers fewer options for customizing requests compared to cURL and requests. It’s less suited for complex API interactions.
• Primarily for downloads: While it can perform GET requests, its main focus is on downloading files.
• No built-in JSON handling: wget doesn’t have built-in support for parsing JSON responses.

In conclusion, while cURL is a versatile tool for Make a GET Request With cURL, Python’s requests library provides a more programmer-friendly interface within Python environments, and wget offers a simple alternative for basic downloads and GET requests from the command line. The best choice depends on the specific requirements of your task and the environment you’re working in.
