Introduction

When working on web applications, sometimes we run into issues that can be quite frustrating. One common problem developers face is posting images from a React frontend to a Django REST API using Redux. If you've encountered the 415 Unsupported Media Type error, you're not alone. In this guide, we’ll explore what causes this error and how to effectively resolve it by properly configuring your requests and API.

The Challenge

In your setup, you're using:

React for the frontend

Django REST Framework for the backend

Redux to manage state

Ant Design for your UI components

You have a form that allows users to upload images, but despite your efforts, the images are not posting correctly to your Django API. This leads to the frustrating 415 Unsupported Media Type error, indicating that the server doesn't recognize or accept the format of the data being sent.

Solution Overview

To effectively resolve this issue, we need to ensure that:

The data is properly formatted as multipart form data.

The headers are correctly set for your Axios post request when sending the image.

Let’s break down the solution step-by-step.

FormData: This built-in JavaScript object allows you to easily construct key/value pairs to send via XMLHttpRequest. It’s crucial for uploading files.

Headers: Adding { headers: { "Content-Type": "multipart/form-data" } } tells the server the kind of data being sent, which resolves the 415 Unsupported Media Type error.
