request-id-flask 0.0.1

Receive and return the value of HTTP X-Request-ID header.

request-id-flask

Attach a unique identifier to every HTTP request in your WSGI application.

request-id-flask is implemented as a WSGI middleware.

The package will do one of two things:

1. Read the X-Request-ID HTTP header from a client HTTP request and return the same X-Request-ID HTTP header in the server HTTP response and is stored in the WSGI environ.

2. Or, when no X-Request-ID HTTP header is present in the client HTTP request, generate a new and unique request_id identifier (using uuid 4) which is stored in the WSGI environ and set as the X-Request-ID HTTP header in the server HTTP responser.

Requirements

• Python 3.6 or above

Installation

You can install the request-id-flask package using pip:

pip install flask-ext-request-id

However, recommended to add it to the requirements.txt file instead.

Access the request_id

The REQUEST_ID is stored in the request environ dictionary and may be accessed from anywhere this is available in Flask.

Usage

from flask import Flask
from request_id import RequestId

app = Flask(__name__)
RequestId(app)
