postbin

A simple Flask webserver to log all incoming requests with their headers and payloads.

Installation

Install postbin using pip:

pip install postbin

Usage

Start the server with

$ postbin

Then make requests, e.g. with curl:

curl -X POST http://127.0.0.1:5000 \
     -H "Content-Type: application/json" \
     -H "Custom-Header: CustomValue" \
     -d '{"key1":"value1","key2":"value2"}'

The postbin prints:

           Request Headers
┏━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━┓
┃         Header ┃ Value            ┃
┡━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━┩
│           Host │ 127.0.0.1:5000   │
│     User-Agent │ curl/7.68.0      │
│         Accept │ */*              │
│   Content-Type │ application/json │
│  Custom-Header │ CustomValue      │
│ Content-Length │ 33               │
└────────────────┴──────────────────┘
           JSON Payload: {'key1': 'value1', 'key2': 'value2'}

Examples
