from flask import request request headers get  your-header-name     request headers behaves like a dictionary  so you can also get your header like you would with any dictionary   request headers  your-header-name

Let s see how we get the params  headers and body in Flask  I m gonna explain with the help of postman     The params keys and values are reflected in the API endpoint  for example key1 and key2 in the endpoint   https   127 0 0 1 upload key1 value1 amp key2 value2  from flask import Flask  request app   Flask   name      app route   upload   def upload       key 1   request args get  key1     key 2   request args get  key2     print key 1     -- gt  value1   print key 2     -- gt  value2   After params  let s now see how to get the headers       header 1   request headers get  header1     header 2   request headers get  header2     print header 1     -- gt  header value1   print header 2     -- gt  header value2   Now let s see how to get the body       file name   request files  file   filename   ref id   request form  referenceId     print ref id     -- gt  WWB9838yb3r47484   so we fetch the uploaded files with request files and text with request form

just note  The different between the methods are  if the header is not exist  request headers get  your-header-name     will return None or no exception  so you can use it like  if request headers get  your-header-name               but the following will throw an error  if request headers  your-header-name     KeyError   your-header-name             You can handle it by  if  your-header-name  in request headers     customHeader   request headers  your-header-name

If any one s trying to fetch all headers that were passed then just simply use   dict request headers    it gives you all the headers in a dict from which you can actually do whatever ops you want to  In my use case I had to forward all headers to another API since the python API was a proxy
