Introduction

This client sends large HTTP data streams to a server to test its ability to handle large data requests.

Prepare the request data

In the client folder create a large file by running the following command:

dd if=/dev/zero of=input bs=4M count=1024

The command above creates a 4 Gigabytes file. You can change the parameters bs and count to configure the data size.

Send a request

Use curl to send a request:

curl -v -X PUT -H "Content-Type: multipart/form-data" -F "data=@./input" http://localhost:8080/test

If you’re using the SpringBoot proxy, use the proxy port:

curl -v -X PUT -H "Content-Type: multipart/form-data" -F "data=@./input" http://localhost:9000/test

OpenShift

To get the external routes for your services, use:

oc get route

This will show you the routes for both the backend and proxy servers. Use these routes instead of localhost when testing with curl.

Send a request using curl

If you’re calling the backend server directly:

curl -v -X PUT -H "Content-Type: multipart/form-data" -F "data=@./input" <backend-server-route>/test

If you’re using the Spring Boot proxy server:

curl -v -X PUT -H "Content-Type: multipart/form-data" -F "data=@./input" <proxy-server-route>/test

To check that output file was sent to the backend server pod:

1. List your pods:

   oc get pods

2. Connect to the backend server pod:

   oc rsh <pod-name>

3. Inside the pod, check the output file in the /deployments/client/ directory.

Clean the data

When you’re done, make sure you perform the following actions:

1) Delete the large sample data file to clean your filesystem.

2) Delete the output file generated by Camel.
