Sorry for the newb question, but I am tearing my hair out over this one. I can successfully POST data to my endpoint URL via a program like FireFox's POSTER. However, I'm trying to post that same JSON data from my app to my endpoint URL (Drupal services push_notifications end point), and for some reason it will not POST successfully. Here is the code that I'm using:
ViewController.m
NSString *urlString1 = @"http://app.com/endpoint001/push_notifications";
NSDictionary *jsonBodyDict = @{@"token":postDeviceID, @"type":@"ios"};
NSData *jsonBodyData = [NSJSONSerialization dataWithJSONObject:jsonBodyDict options:kNilOptions error:nil];
// watch out: error is nil here, but you never do that in production code. Do proper checks!
NSString *urlString2 = [NSString stringWithFormat:@"http://app.com/endpoint001/push_notifications?token=%@&type=%@",
postDeviceID,@"ios"];
NSMutableURLRequest *request = [NSMutableURLRequest new];
request.HTTPMethod = @"POST";
// for alternative 1:
[request setURL:[NSURL URLWithString:urlString1]];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPBody:jsonBodyData];
[request addValue:csrfToken forHTTPHeaderField:@"X-CSRF-Token"];
// for alternative 2:
[request setURL:[NSURL URLWithString:urlString2]];
// no body needed, though that ultimately depends on your server. Also, I didn't test this for lack of a backend :)
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config
delegate:nil
delegateQueue:[NSOperationQueue mainQueue]];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request
completionHandler:^(NSData * _Nullable data,
NSURLResponse * _Nullable response,
NSError * _Nullable error) {
NSLog(@"Yay, done! Check for errors in response!");
NSHTTPURLResponse *asHTTPResponse = (NSHTTPURLResponse *) response;
NSLog(@"The response is: %@", asHTTPResponse);
// set a breakpoint on the last NSLog and investigate the response in the debugger
// if you get data, you can inspect that, too. If it's JSON, do one of these:
NSDictionary *forJSONObject = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:nil];
// or
NSArray *forJSONArray = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:nil];
NSLog(@"One of these might exist - object: %@ \n array: %@", forJSONObject, forJSONArray);
}];
[task resume];
Note: I've put this code in AFTER my user already successfully logs in, so I'm not sure starting a whole new connection is necessary? How can I POST my data to the server if a session and CSRF Token already exists? What should my code look like? Whoever answers this question is going on my Christmas list... O_O
