Send JSON REST Request, Get JSON Response

See more REST Examples

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON). Ruby

require 'chilkat'

success = false

# This example will create a bucket in Google Cloud Storage.

# It requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

gAuth = Chilkat::CkAuthGoogle.new()
# Obtain an access token as shown in one of the following examples:
# See Get Access Token using a Service Account JSON Key
# See Get Access Token using a P12 File

rest = Chilkat::CkRest.new()

# Connect using TLS.
bAutoReconnect = true
success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect)

# Provide the authentication credentials (i.e. the access key)
success = rest.SetAuthGoogle(gAuth)

# Build the JSON request body for creating a bucket.
# The only required property is the "name", but we'll add more
# to make a better example..
jsonReqBody = Chilkat::CkJsonObject.new()
jsonReqBody.AppendString("name","chilkat-bucket-c")
jsonReqBody.AppendString("kind","storage#bucket")
jsonReqBody.AppendString("location","US")

objVersioning = Chilkat::CkJsonObject.new()
jsonReqBody.AppendObject2("versioning",objVersioning)
objVersioning.AppendBool("enabled",true)

# Show the HTTP request body we'll be sending.
print jsonReqBody.emit() + "\n";

# Add the required query parameter.
# See https://cloud.google.com/storage/docs/json_api/v1/buckets/insert
success = rest.AddQueryParam("project","chilkattest-1050")

# Add the Content-Type HTTP request header.
success = rest.AddHeader("Content-Type","application/json; charset=UTF-8")

jsonResponseStr = rest.fullRequestString("POST","/storage/v1/b",jsonReqBody.emit())
if (rest.get_LastMethodSuccess() == false)
    print rest.lastErrorText() + "\n";
    exit
end

# Show the JSON response.  (See below for a sample JSON response.)
print "Json Response: " + jsonResponseStr + "\n";
