My commitment statement involves sending multiple requests to eBay, each time using the properties of a matchCenterItem as parameters. Once all instances have been processed, I aim to transmit all the responses to my iOS application.
However, my effort to achieve this in response.success is met with an error message indicating that httpResponse is not defined, despite being defined earlier in the script.
Parse.Cloud.define("MatchCenterTest", function(request, response) {
//defines which parse class to iterate through
var matchCenterItem = Parse.Object.extend("matchCenterItem");
var query = new Parse.Query(matchCenterItem);
var promises = [];
//setting the limit of items at 10 for now
query.limit(10);
query.find().then(function(results) {
for (i=0; i<results.length; i++) {
url = 'http://svcs.ebay.com/services/search/FindingService/v1';
//push function containing criteria for every matchCenterItem into promises array
promises.push(function() {
return Parse.Cloud.httpRequest({
url: url,
params: {
'OPERATION-NAME' : 'findItemsByKeywords',
'SERVICE-VERSION' : '1.12.0',
'SECURITY-APPNAME' : '*APP ID GOES HERE*',
'GLOBAL-ID' : 'EBAY-US',
'RESPONSE-DATA-FORMAT' : 'JSON',
'REST-PAYLOAD&sortOrder' : 'BestMatch',
'paginationInput.entriesPerPage' : '3',
'outputSelector=AspectHistogram&itemFilter(0).name=Condition&itemFilter(0).value(0)' : results[i].get('itemCondition'),
'itemFilter(1).name=MaxPrice&itemFilter(1).value' : results[i].get('maxPrice'),
'itemFilter(1).paramName=Currency&itemFilter(1).paramValue' : 'USD',
'itemFilter(2).name=MinPrice&itemFilter(2).value' : results[i].get('minPrice'),
'itemFilter(2).paramName=Currency&itemFilter(2).paramValue' : 'USD',
//'itemFilter(3).name=LocatedIn&itemFilter(3).Value' : request.params.itemLocation,
'itemFilter(3).name=ListingType&itemFilter(3).value' : 'FixedPrice',
'keywords' : results[i].get('searchTerm'),
}
});
});
}
Parse.Promise.when(promises).then(function() {
var eBayResults = JSON.parse(httpResponse.text);
for (i=0; i<eBayResults.length; i++)
{
console.log(eBayResults[i]); // So you can see what the response
// looks like for each httpRequest that was made
}
// if this is the end of your function, call
response.success(eBayResults);
}, function(err) {
console.log('error!');
response.error();
});
});
});
