How do we access the Magento product detail to AEM? - Magento AEM integration

There are cases where we need to access Magento data to AEM. AEM By default supports Magento plugin - AEM Extension to import data from Magento.

In some scenarios, Magento exposes the products over API. In this case, we can access the products from Magento using the below-explained method.

Note: In this example, the Magento API authorization is based on the bearer token. The API response is in JSON format.
Java code - to invoke the API and access the products.
//Create a HTTP connection management
DefaultHttpClient httpClient = new DefaultHttpClient();

//HttpGet helps posting client data the server.
HttpGet getMagentoRequest = new HttpGet("Magento API url");

//Add authorization token as part of request header
getMagentoRequest.addHeader("Authorization", "Bearer TOKEN");

//Invoke the API to retrieve response
HttpResponse response = httpClient.execute(getMagentoRequest);

//Read the response using buffered readerr
BufferedReader magentoBr = new BufferedReader(new InputStreamReader((response.getEntity().getContent())));

String retrievedResult;
String resultString="" ;

//capture the entire response in sting format
while ((retrievedResult = magentoBr.readLine()) != null) {
resultString = resultString + retrievedResult;
}

//Parse the JSON data present in the string format
JSONParser parse = new JSONParser();
//Type caste the parsed json data in json object
JSONObject jsonData = (JSONObject)parse.parse(resultString);

How to retrieve the JSON data?
Say we have below JSON format which has a primary child and secondary child elements

{
"id": "file",
"value": "File",
"popup": {
"menuitem": [{
"value": "New",
"onclick": "CreateNewDoc()"
}
]
}
}

//get the individual item from JSON
String ID = (String) jsonData.get( "id" );
//Now append ID on your bean class object

//Store the JSON object in JSON array as objects (For level 1 array element)

JSONArray menuItems = (JSONArray) jobj.get("menuitem");

for(int i=0;i<menuItems.size();i++)
{
//Store the JSON objects in an array
//Get the index of the JSON object and print the values as per the index
JSONObject childItem = (JSONObject)menuItems.get(i);
String value = (String) childItem.get("value");
//Now append value on your bean class object
String onclick = (String) childItem.get("onclick");
//Now append onclick on your bean class object
}
Once we execute the code, we will have the parsed JSON Data available in Bean class.

Now in your HTL, iterate over the bean class objects and display the response.
