How do I POST JSON data with cURL?

How to POST JSON data with cURL 📮🔗

Are you trying to test your Spring REST application with cURL? Do you want to post JSON data to it, but you're running into errors? Don't worry, we've got you covered! In this guide, we'll walk you through the process of how to properly POST JSON data with cURL. Let's get started! 🚀

The problem 😓

You're using cURL on Ubuntu to test your Spring REST application, and you want to send a JSON payload using the POST method. However, when you run the cURL command, you encounter the following error:

HTTP/1.1 415 Unsupported Media Type

The error description says: "The server refused this request because the request entity is in a format not supported by the requested resource for the requested method."

The solution 💡

To fix the error and successfully POST JSON data with cURL, you need to make sure you're using the correct format in your cURL command. Here's an example of the correct format:

curl -i \
    -H "Accept: application/json" \
    -H "Content-Type: application/json" \
    -X POST -d '{
        "value":"30",
        "type":"Tip 3",
        "targetModule":"Target 3",
        "configurationGroup":null,
        "name":"Configuration Deneme 3",
        "description":null,
        "identity":"Configuration Deneme 3",
        "version":0,
        "systemId":3,
        "active":true
    }' \
    http://localhost:8080/xx/xxx/xxxx

This command includes the following important additions:

• The -H "Content-Type: application/json" header tells the server that you're sending JSON data.

• The -d option is followed by the JSON payload enclosed in single quotes.

Additional tips and explanations ✨🔍

• Make sure the URL in your cURL command is correct and points to the right endpoint of your Spring REST application.

• Double-check that your Spring REST application is properly configured to accept JSON data for the POST method.

• If you're encountering any other errors or issues, check the logs of your application (e.g., Tomcat logs) for more information.
