Curl Part 4: Exploring the PUT and PATCH methods

In this article, we will continue discussing curl and how to use the PATCH and PUT methods in order to update data. Here are a few examples of how to use the curl command with the UPDATE method:

Simple PUT request

To make a simple PUT request to a server, you can use the following syntax:

$ curl -X PUT -d "data" http://example.com/resource

This will send a PUT request to the specified URL, replacing the existing resource with the specified data.

PUT request with headers

You can include additional headers in your PUT request by using the -H option.

For example:

$ curl -X PUT -H "Content-Type: application/json" -d '{"key":"value"}' http://example.com/resource

This will send a PUT request with a “Content-Type” header set to “application/json” and the specified JSON data in the request body.

PUT request with a file

You can use the -T option to upload a file in a PUT request.

For example:

$ curl -X PUT -T "/path/to/file.txt" http://example.com/resource

This will send a PUT request containing the specified file included in the request body.

Simple PATCH request

To make a simple PATCH request to a server, you can use the following syntax:

$ curl -X PATCH -d "data" http://example.com/resource

This will send a PATCH request to the specified URL, updating the existing resource with the specified data.

PATCH request with headers

You can include additional headers in your PATCH request by using the -H option.

For example:

$ curl -X PATCH -H "Content-Type: application/json" -d '{"key":"value"}' http://example.com/resource

This will send a PATCH request with a “Content-Type” header set to “application/json” and the specified JSON data in the request body.

This was the final part of the series, the curl command offers many other options and features that you can use to customize your requests and automate tasks. For more information, refer to the curl documentation or use the curl --help command.
