Im trying to make request to multiple URLs to download the HTML and later turn it into a JSON format. Where I'm running into trouble is when i try to make request to multiple URLs in the for loop. I'm no master on this with async requests so, this might be a obvious mistake to you guys, but I can't find a answer to the question.
If I try to run it without the loop (just referencing a single object in the TFHppleElement-array) it seems to work, but as soon as I'm looping it, the request won't seem to be made.
Does not work:
func getData(data: [TFHppleElement]) {
for index in data{
let thisurl="https://theurl.org\(index.firstChild.objectForKey("href"))"
let session = NSURLSession.sharedSession()
let request = NSMutableURLRequest(URL: NSURL(string: thisurl)!)
request.HTTPMethod = "GET"
let task = session.dataTaskWithRequest(request){
(data : NSData?, response : NSURLResponse?, error : NSError?) -> Void in
if error == nil{
let parser = HTMLParser()
parser.parseNode(data!, xPathString: "//span[@class='odd']", callback: self.createJSON)
}else{
print("Request not working")
}
}
task.resume()
}
}
Works:
func getData(data: [TFHppleElement]) {
// for index in data{
let thisurl="https://theurl.org\(data[0].objectForKey("href"))"
let session = NSURLSession.sharedSession()
let request = NSMutableURLRequest(URL: NSURL(string: thisurl)!)
request.HTTPMethod = "GET"
let task = session.dataTaskWithRequest(request){
(data : NSData?, response : NSURLResponse?, error : NSError?) -> Void in
if error == nil{
let parser = HTMLParser()
parser.parseNode(data!, xPathString: "//span[@class='odd']", callback: self.createJSON)
}else{
print("Request not working")
}
}
task.resume()
//}
}
I haven't been programming for a while, so I'm sorry if it might be an obvious mistake.
