axios post request to send form data

📝 Title: Sending Form Data with Axios POST Request Made Easy!

👋 Hey there, tech enthusiasts! Are you facing issues with setting up form data in your Axios POST request? Don't worry, I've got you covered with simple solutions and a sprinkle of cool vibes. Let's dive in and get things rolling! 💪

🚧 The Problem: Null Values in POJO Class

So, you've set up your Axios POST request to hit the controller's URL, but all you're getting is null values in your POJO class. What's going wrong here? 🤔

🕵️ Investigating the Issue:

• Checking the developer tools in Chrome, the payload contains the data. So, the issue is not with the data being sent.

• You have defined the request body like this:

var body = {
    userName: 'Fred',
    userEmail: 'Flintstone@gmail.com'
}

• Here comes the culprit 👉 You're missing something in your Axios setup! Let's fix that. 😉

💡 The Solution: Setting the Headers

To ensure the form data is sent correctly, we need to set the correct headers in our Axios POST request. Adding a Content-Type header does the magic! 🎩

Include the following code snippet in your Axios setup:

headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
}

💡 Pro Tip: Make sure to use the correct Content-Type value for form data, which is 'application/x-www-form-urlencoded'.

🚦 Handling the Error: Missing Boundary

Wait, what's happening now? The request throws an error, saying: "Error in posting multipart/form-data. Content-Type header is missing boundary." Can't catch a break, can we? 🤦‍♀️

🔎 Analyzing the Error:

• When you set Content-Type as 'multipart/form-data', Axios expects a "boundary" specification, which is missing in your request.

• This "boundary" separates different parts of the request payload.

💡 The Solution: Specifying the Boundary

To fix this issue, we need to include the boundary specification in our Content-Type header. Let's update the header within the Axios setup:

headers: {
    'Content-Type': 'multipart/form-data; boundary=some-random-string'
}

Now, your POST request will have the required boundary specification and everything should work like a charm! ✨

🙌 Success with Postman - What's the Secret?

You mentioned that the same request works fine in Postman, but fails with Axios. What's Postman doing differently? 🤔

🤫 The Hidden Truth:

• Postman is smart and automatically includes the necessary headers, including the boundary, when you select the form-data option.

• But, with Axios, you need to manually specify the boundary in the Content-Type header, as explained above.
