require 'chilkat'

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

# Sends the following PUT request:
# PUT https://marketplace.walmartapis.com/v2/inventory?sku={SKU}

sbUrl = Chilkat::CkStringBuilder.new()
success = sbUrl.Append("https://marketplace.walmartapis.com/v2/inventory?sku={SKU}")
numReplaced = sbUrl.Replace("{SKU}","HOPP~904~51041")

requestMethod = "PUT"

# First we need to generate a signature for our request.
# The signature needs to be re-generated for each new Walmart HTTP request.
authUtil = Chilkat::CkAuthUtil.new()

wmConsumerId = "WALMART_CONSUMER_ID"
wmPrivateKey = "WALMART_PRIVATE_KEY"
jsonStr = authUtil.walmartSignature(sbUrl.getAsString(),wmConsumerId,wmPrivateKey,requestMethod)
if (authUtil.get_LastMethodSuccess() != true)
    print authUtil.lastErrorText() + "\n";
    exit
end

# The JSON returned by WalmartSignature contains the values to be used in the following
# header fields: WM_SEC.AUTH_SIGNATURE, WM_SEC.TIMESTAMP, and WM_QOS.CORRELATION_ID
json = Chilkat::CkJsonObject.new()
json.Load(jsonStr)

http = Chilkat::CkHttp.new()
http.SetRequestHeader("WM_SVC.NAME","Walmart Marketplace")
http.SetRequestHeader("WM_QOS.CORRELATION_ID",json.stringOf("correlation_id"))
http.SetRequestHeader("WM_SEC.TIMESTAMP",json.stringOf("timestamp"))
http.SetRequestHeader("WM_SEC.AUTH_SIGNATURE",json.stringOf("signature"))
http.SetRequestHeader("WM_CONSUMER.ID",wmConsumerId)
http.put_Accept("application/xml")

# Note: Do not explicitly set the "Host" header.  Chilkat will set it automatically.

# The body of the PUT request will be XML that looks like this:

# 	<?xml version="1.0" encoding="utf-8" ?>
# 	<wm:inventory xmlns:wm="http://walmart.com/">
# 	    <wm:sku>HOPP~904~51041</wm:sku>
# 	    <wm:quantity>
# 	        <wm:unit>EACH</wm:unit>
# 	        <wm:amount>235</wm:amount>
# 	    </wm:quantity>
# 	    <wm:fulfillmentLagTime>5</wm:fulfillmentLagTime>
# 	</wm:inventory>

# Build the XML request body:
originalAmount = 234

xmlBody = Chilkat::CkXml.new()
xmlBody.put_Tag("wm:inventory")
xmlBody.AddAttribute("xmlns:wm","http://walmart.com/")
xmlBody.UpdateChildContent("wm:sku","HOPP~904~51041")
xmlBody.UpdateChildContent("wm:quantity|wm:unit","EACH")
xmlBody.UpdateChildContentInt("wm:quantity|wm:amount",originalAmount + 1)
xmlBody.UpdateChildContent("wm:fulfillmentLagTime","5")

print "PUT request body:" + "\n";
print xmlBody.getXml() + "\n";
print "--" + "\n";

# This is a simple PUT that can be sent w/ the PutText method.
xmlStr = http.putText(sbUrl.getAsString(),xmlBody.getXml(),"utf-8","application/xml",false,false)
if (http.get_LastMethodSuccess() != true)
    print http.lastErrorText() + "\n";
    exit
end

xml = Chilkat::CkXml.new()
xml.LoadXml(xmlStr)

# A successful response should have a 200 response status
if (http.get_LastStatus() != 200)
    print xml.getXml() + "\n";
    print "Response Status Code: " + http.get_LastStatus().to_s() + "\n";
    print "Failed." + "\n";
    exit
end

# A sample XML response is shown below..
print xml.getXml() + "\n";
print "--" + "\n";
print "Success!" + "\n";
