React POST request

By design, the POST request method requests that a web server accept the data enclosed in the body of the request message, most likely for storing it . It is often used when uploading a file or when submitting a completed web form. In contrast, the HTTP GET request method retrieves information from the server.

First, we specify the ‘method’, POST. Then, we specify the value of ‘mode’. Since the Flask server is being hosted on a different port on our machine (8080) than the React app, we have to specify the value as ‘cors’. All this means is that data will be sent across origins.

In React Native, you can request data from an API over the network using the fetch() method. The syntax is simple as follows: fetch(‘https://examples.com/data.json’); We simply pass the URL to the fetch method to make a request.23 Kas 2020
