CURL is a command-line tool that allows making HTTP requests to test APIs and supports a wide range of options and protocols, making it a powerful tool for tasks like downloading files, testing APIs, and performing various network-related tasks. In this section, we'll see how to use cURL to send GET requests.

If you want to know more about cURL, recommend reading this article:

What is cURL and What is the cURL Command Used for?
What is cURL in API?“Curl” stands for “Client for URLs” and is a command-line tool and library for transferring data with URLs. It is widely used for making HTTP requests to interact with web APIs.

What are GET Requests?

A GET request is one of the HTTP methods used by the World Wide Web. It is a type of request that a client (such as a web browser) makes to a web server to retrieve or get data from a specified resource. In simpler terms, a GET request is used when you want to retrieve information from a server.

When you enter a URL into a web browser and press Enter, the browser typically sends a GET request to the server specified in the URL. This request asks the server to provide the requested resource, which could be a web page, an image, a file, or any other type of data.

Here's a basic example of a GET request:

httpCopy code
GET /path/to/resource HTTP/1.1
Host: www.example.com

In this example:

  • GET is the HTTP method indicating that the client is requesting data.
  • /path/to/resource is the specific resource path on the server.
  • HTTP/1.1 is the version of the HTTP protocol being used.
  • Host: ``www.example.com is a header specifying the domain name of the server.

How to Send GET Requests with cURL

To send a GET request using cURL, you can use the curl command in your terminal or command prompt. Here's a basic example:

curl https://www.example.com

This simple command sends a GET request to https://www.example.com and prints the server's response to the terminal.

You can also include various options and additional parameters with the cURL command. Here are a few examples:

Step 1. Adding Headers:

curl -H "Authorization: Bearer YOUR_TOKEN" https://api.example.com/data

In this example, the -H option is used to include an Authorization header with a bearer token.

Step 2. Following Redirects:

curl -L https://www.example.com

The -L option tells cURL to follow redirects. If the server responds with a redirect (HTTP status code 3xx), cURL will automatically request the new location.

Step 3. Saving Output to a File:

curl -o output.html https://www.example.com

The -o option is used to save the output to a file. In this case, the response from the server will be saved to a file named output.html.

Step 4. Passing Query Parameters:

curl "https://api.example.com/data?param1=value1&param2=value2"

You can include query parameters in the URL to send additional information to the server. This helps validate that the API returns the correct status code like 200 OK.
