I'm (trying to) learn the Swift's Apple language. I'm at Playground and using Xcode 6 Beta. I'm trying to do a simple JSON Post to a local NodeJS server. I already had googled about it and the major tutorials explain how to do it in a project, not at PLAYGROUND, than don't write stupid thinks like: "google it" or "it's obvious" or "look this link" or never-tested-and-not-functional-code
This is what i'm trying:
var request = NSURLRequest(URL: NSURL(string: "http://localhost:3000"), cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response : NSURLResponse?
var error : NSError?
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
I had tried:
var dataString = "some data"
var request = NSMutableURLRequest(URL: NSURL(string: "http://posttestserver.com/post.php"))
request.HTTPMethod = "POST"
let data = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
var requestBodyData: NSData = data
request.HTTPBody = requestBodyData
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: false)
println("sending request...")
connection.start()
Thank you! :)
Nate's answer was great but I had to change the request.setvalue for it to work on my server
// create the request & response
var request = NSMutableURLRequest(URL: NSURL(string: "http://requestb.in/1ema2pl1"), cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response: NSURLResponse?
var error: NSError?
// create some JSON data and configure the request
let jsonString = "json=[{\"str\":\"Hello\",\"num\":1},{\"str\":\"Goodbye\",\"num\":99}]"
request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
// send the request
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
// look at the response
if let httpResponse = response as? NSHTTPURLResponse {
println("HTTP response: \(httpResponse.statusCode)")
} else {
println("No HTTP response")
}
It looks like you have all the right pieces, just not in quite the right order:
// create the request & response
var request = NSMutableURLRequest(URL: NSURL(string: "http://requestb.in/1ema2pl1"), cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response: NSURLResponse?
var error: NSError?
// create some JSON data and configure the request
let jsonString = "json=[{\"str\":\"Hello\",\"num\":1},{\"str\":\"Goodbye\",\"num\":99}]"
request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
// send the request
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
// look at the response
if let httpResponse = response as? NSHTTPURLResponse {
println("HTTP response: \(httpResponse.statusCode)")
} else {
println("No HTTP response")
}
