WSO2 Sequence: capture headers of incoming request

By : Steven Rao
Date : September 15 2020, 03:00 AM
should help you out Authorization Header is used in API Manager for internal authorization purposes only, and that header is normally removed from the outgoing request(from APIM gw to backend) before it is sent to backend. This happens at APIAuthenticationHandler level. And the custom in sequence you attached to API will be executed after the APIAuthenticationHandler. You may refer the message flow diagram in [1] for a better understanding.
Now let's see how this APIAuthenticationHandler is applied by default on the API's synapse file. (You may find this at /repository/deployments/server/synapse-configs/api folder)
code :
<handler class="org.wso2.carbon.apimgt.gateway.handlers.security.APIAuthenticationHandler">
      <property name="RemoveOAuthHeadersFromOutMessage" value="true"/>
      <property name="APILevelPolicy" value=""/>
      <property name="APISecurity" value="oauth2"/>
<property name="RemoveOAuthHeadersFromOutMessage" value="false"/>
INFO - APIDeployer API: admin--PizzaShackAPI:v1.0.0 has been updated from the file: /wso2am-2.6.0/repository/deployment/server/synapse-configs/default/api/admin--PizzaShackAPI_v1.0.0.xml

How to process incoming custorm headers in http request and then reverse proxy the request depend on the result

By : Alex K

I hope this helps . You need to issue a subrequest in terms of nginx.
You may do it using one of Eval modules and then parse response by regexp, but it is not recommended.
code :
init_by_lua 'require "cjson"';

location /auth {
    proxy_pass http://authserver:12345/authorize;
location /myService {
    access_by_lua '
        res = ngx.location.capture("/auth")
        if res.status == ngx.HTTP_OK then
            local response = cjson.decode( res.body )
            if response.valid and response.valid == "true" then
    proxy_pass http://host:port/myservice/;

How to capture and read headers of incoming HTTP requests in Flask?

By : Aflah Boufarguine
Date : March 29 2020, 07:55 AM
it helps some times You can use flask.request.headers. It's a werkzeug.datastructures.EnvironHeaders object, but you can use it as a normal dict.
For example:
code :
from flask import Flask, request

app = Flask(__name__)

def main():

if __name__ == '__main__':
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Dnt: 1
Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.6,en;q=0.4
Accept-Encoding: gzip, deflate, sdch
Cache-Control: max-age=0
Connection: keep-alive
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36

How to get headers for a POST request from aws lambda event object (in python) where the incoming request has empty body

By : Vinoth Kumar
Date : March 29 2020, 07:55 AM
wish helps you I was able to get this working without any problem. I can't tell from your post why your event object is empty. My best guess is that you forgot to add the headers to the "HTTP Request Headers" section of the Method Request.
Here's my Lambda function:
code :
from __future__ import print_function

import json

print('Loading function')

def lambda_handler(event, context):
    print("Received event: " + json.dumps(event, indent=2))

    print("Content-Type = " + event['Content-Type'])
    print("Content-Length = " + event['Content-Length'])
    print("X-Goog-Channel-ID = " + event['X-Goog-Channel-ID'])
    print("X-Goog-Channel-Token = " + event['X-Goog-Channel-Token'])
    print("X-Goog-Channel-Expiration = " + event['X-Goog-Channel-Expiration'])
    print("X-Goog-Resource-ID = " + event['X-Goog-Resource-ID'])
    print("X-Goog-Resource-URI = " + event['X-Goog-Resource-URI'])
    print("X-Goog-Resource-State = " + event['X-Goog-Resource-State'])
    print("X-Goog-Changed = " + event['X-Goog-Changed'])
    print("X-Goog-Message-Number = " + event['X-Goog-Message-Number'])
    print("body = " + event['body'])

    return {
        'statusCode': '200',
        'body': event['body'],
        'headers': {
            'Content-Type': 'application/json',
            'X-Goog-Channel-ID': event['X-Goog-Channel-ID'],
            'X-Goog-Channel-Token': event['X-Goog-Channel-Token'],
            'X-Goog-Channel-Expiration': event['X-Goog-Channel-Expiration'],
            'X-Goog-Resource-ID': event['X-Goog-Resource-ID'],
            'X-Goog-Resource-URI': event['X-Goog-Resource-URI'],
            'X-Goog-Resource-State': event['X-Goog-Resource-State'],
            'X-Goog-Changed': event['X-Goog-Changed'],
            'X-Goog-Message-Number': event['X-Goog-Message-Number'],
  "body": "Test input body content",
  "headers": {
    "X-Goog-Resource-ID": "SuIweVX_iBzKmM5PQVMbIDYFrr8",
    "X-Goog-Channel-ID": "",
    "X-Goog-Resource-State": "update",
    "X-Goog-Changed": "content,properties",
    "X-Goog-Resource-URI": "https://www.googleapis.com/drive/v3/files/1QvVo67IJ3_o5g2tCyxpNA29JHx183-bOOblKMoSAGv4?acknowledgeAbuse=false&alt=json",
    "X-Goog-Message-Number": "480896",
    "X-Goog-Channel-Token": "to66728b-21c7-4605-8445-d7a297b9ae7f",
