Setup command line tools to work with IBM Cloudant

Command line tools are always welcome. Today i need to setup my MAC to work with IBM Cloudant

Install curl on your MAC if you haven’t done it yet.

1 – You need to setup the Cloudant DB using your IBM Cloud account.

2 – Go to service credentials and get your username, password and hostname

Sample:
"username": "xxxx-xxx-xxx-bluemix",
"password": "12345678901234567890",
"host": "xxxx-xxx-xxx-bluemix.cloudant.com"

3 – Test the connection

curl –v –u xxxx-xxx-xxx-bluemix 'https://xxxx-xxx-xxx-bluemix.cloudant.com'

The command will prompt for the password: 12345678901234567890

You will see a lot off lines but pay attention on the line Authorization: Basic. This will be used to setup acurl (authorized curl) to avoid type the password every time you use curl.

* Using HTTP2, server supports multi-use
* Connection state changed (HTTP/2 confirmed)
* Copying HTTP/2 data in stream buffer to connection buffer after upgrade: len=0
* Server auth using Basic with user ‘xxxx-xxx-xxx-bluemix’
* Using Stream ID: 1 (easy handle 0x7fabd0805800)
> GET / HTTP/2
> Host: xxxx-xxx-xxx-bluemix.cloudant.com
> Authorization: Basic asddadasdDASDdaDadaDSERQERQRQERQEDSGSFDGSFDG==

4 – Edit the .bash_profile or .bashrc file in any text editor. For example, from the command line, issue the following command:
open –e .bash_profile

5 – Add the following line to the file, then save the file.
alias acurl="curl -s --proto '=https' -g -H 'Authorization: Basic asddadasdDASDdaDadaDSERQERQRQERQEDSGSFDGSFDG=='"

6 – On the terminal run : source .bash_profile

7 – Issue a command using the new alias. For example, issue a command to view your account information.
acurl -X GET 'https://xxxx-xxx-xxx-bluemix.cloudant.com'

TIP: The hostname is not friendly you can edit your hosts file and create an alias:

On MAC terminal type: sudo vi /etc/hosts

ping your hostname to get the ip address

add a line like this one bellow:

<ip address> xxxx-xxx-xxx -bluemix.cloudant.com keniodb.cloudant.com

Save the hosts file

test the connection

acurl -X GET 'https://keniodb.cloudant.com

Forrester Names IBM a Leader in Conversational Computing Platforms Wave

IBM Watson Assistant is named as a Leader in conversational computing. It has become increasingly important for businesses to build engaging interactions that deliver value to their customers, and IBM is proud to offer technologies that help developers and enterprises enhance those experiences.

The report evaluated the most significant conversational computing platforms, diving into each vendor’s current offering and strategy and including customer feedback.

I always work with IBM Watson Assistant to create Virtual Assistants, since the name was “dialog”. This service is my first option to create conversational applications.

Configuring Cross Origin Resource Sharing on a Liberty server

You can enable Cross Origin Resource Sharing (CORS) for your web applications on a Liberty server.

Enabling CORS will allow JavaScript clients to make requests against your application on the Liberty server even if the client and the server are on two different domains. Web browsers prevent these requests due to same-origin policy.

I create the following configuration on my local machine on server.xml file:

<cors domain="/ApplicationContext" <-- application context. It will work only for this app.
   allowedOrigins="http://localhost:8080" <-- this is my local Node.js Server.
   allowedMethods="GET, HEAD, POST, PUT"
   allowedHeaders="Referer, Cache-Control, Pragma, Accept, Accept-Language, Accept-Encoding, Accept-Charset, Content-Type, Content-Length, User-Agent, Authorization, passwd, X-Update-Nonce, X-Shindig-ST, X-IC-CRE-Request-Origin, X-IC-CRE-User, X-LConn-Auth, Accept*, Content*, Access-Control-Allow-Origin*"
exposeHeaders="Content-Type, Last-Modified, etag"
allowCredentials="true" maxAge="3600" />

SSL Handshake error when connect to Watson API’s

I start a new java project on eclipse using the SDK for Watson.
When i try to connect on any watson service i got the error:

CWPKI0022E: SSL HANDSHAKE FAILURE: A signer with SubjectDN CN=*.watsonplatform.net, O=International Business Machines Corporation,
L=Armonk, ST=New York, C=US was sent from the target host

This error means, that the local Liberty trust store does not have the correct signer certificate from the remote WATSON website where you tries to connect to.
It’s a certificate error. To solve the problem on my MAC i just do the following:

1 – Download the cetificate. The easy way i found was:

openssl s_client -host https://gateway.watsonplatform.net -port 443 -prexit -showcerts

2 – Create a text file with the first certificate

3 – Import the certificate on the truststore

keytool -import -alias watsonsigner -file cert1.pem -keystore /Users/[pathto key.jks]/key.jks -storepass password -storetype jks
