request.getreader()

The request.getreader() method is used to get the input stream reader for the request entity.

Syntax:

reader = request.getreader()

Parameters:

This method doesn't accept any parameter.

Return value:

The method returns a buffered input stream reader object.

Description:

The request.getreader() method is used to read the request body as text. It returns a buffered input stream reader object that can be used to read the body of the request. The method reads the input stream once and caches the result in memory so that it can be read multiple times.

Example:

from flask import Flask, request

app = Flask(__name__)

@app.route('/post',methods=['POST'])
def post_data():

    reader = request.getreader()

    data = reader.read().decode("utf-8")
        
    return data

if __name__ == '__main__':
    app.run()

In the above example, we are using request.getreader() to read the request body and returning it as a response. We have used decode("utf-8") to convert the bytes data to string data.

Conclusion:

The request.getreader() method is useful when we want to read the request body as text. It gives us the input stream reader object that can be used to read the body of the request.
