Introduction

The most popular connector probably is HTTP connector. However, for the enterprise application, this is not good enough. We need to setup HTTPS connect. Since Anypoint Studio, previously called Mule Studio, the configuration of HTTPS has been change. In this blog, I am going document the procedures on how to setup the HTTPS connector for the on-premise application, together with few other technical aspects. Here is the flow I have setup:

In this flow, I have few interesting parts. One is about content-based-routing, and the other is how to setup response content-type. In my case, I setup it as applicaiton/json.

Generate Self-signed Keystore

For the self-signed certificates, we can use keytool coming with JDK. First created a directory name something like certs. In my case, it is located at:

/Users/Gary2013/AnypointStudio-3.7/certs

Now inside the certs directory, execute the following command:

keytool -genkey -alias mule-server -keyalg RSA -keystore keystore.jks

That is all you need to do!

Setup HTTPS Connector

The following 2 pictures show where to put the certificates. In order to setup HTTPS connector, we need to configure 2 pages from the Anypoint Studio as shown below:

Setup The Mule Flow

The flow setup is not that complicated. Here I just provide the configuration file. For the details, I will provide a video, you can my youtube video.

From the above xml file, you may see that I have configured a HTTP and HTTPS connectors. The HTTPS configuration can be view in the following xml form:

You may note that the variable"${https.port.onpremise}". This together with other parameters are defined in the file name mule-app.properties.

Test The Flow

I use PostMan to test the flow for GET and POST methods with following URL:

https://localhost:8443/inventory

To test POST method, put the following JSON into the body of the PostMan:

{
  "name": "Barack Obama",
  "phone": "888-555-8888",
  "address": "1600 Pennsylvania Avenue Northwest, Washington, DC 20500",
  "Title" : "US President"
}

You should get the same json back as the following:

{
  "name": "Barack Obama",
  "phone": "888-555-8888",
  "address": "1600 Pennsylvania Avenue Northwest, Washington, DC 20500",
  "Title": "US President"
}

To test GET method, you use the following URL:

https://localhost:8443/inventory?name=Gary Liu Jr.

You should see the following JSON output:

{
  "name": "Gary Liu Jr."
}

Conclusion

This blog explains the basic procedure to configure HTTPS connector together with few other interesting aspects of mule flow, such as, content-base-routing, response content-type setup etc.
