问题
I'm working on a simple prototype and need to test sending push notifications from one device to another.
I've emailed Urban Airship to turn on the "Allow Push From Device" for my application - and they did turn it on.
I'm trying to use NSURLConnection to send the push notification from the device.
This is my code:
- (void) test {
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://go.urbanairship.com/api/push"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSDictionary * push = @{@"device_tokens":@[@"<token>"], @"aps":@{@"alert":@"TEST", @"sound":@"default"}};
NSData * pushdata = [NSJSONSerialization dataWithJSONObject:push options:0 error:NULL];
[request setHTTPBody:pushdata];
[NSURLConnection connectionWithRequest:request delegate:self];
}
- (void) connection:(NSURLConnection *) connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *) challenge {
if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPBasic]) {
NSURLCredential * credential = [[NSURLCredential alloc] initWithUser:@"<app key>" password:@"<app secret>" persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
[credential release];
}
}
- (void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *) response {
NSHTTPURLResponse * res = (NSHTTPURLResponse *) response;
NSLog(@"response: %@",res);
NSLog(@"res %i\n",res.statusCode);
}
Anyone else done this successfully?
回答1:
Taking a look at Urban Airship's guide to troubleshooting HTTP status codes, and the documentation for the push API, my guess would be that you need to add a trailing slash to the URL:
[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]

Example Using the V3 API...
-(void)richPushNotification{
NSDictionary *push = @{
@"audience" : @{
@"device_token" : deviceToken
},
@"device_types" : @[ @"ios" ],
@"notification" : @{
@"ios" : @{
@"alert":Message,
@"sound":@"default",
@"badge":@"auto",
}
},
@"message": @{
@"title": Message,
@"body": @"<html><body><h1>blah blah</h1> etc...</html>",
@"content_type": @"text/html",
@"extra": @{
@"offer_id" : @"608f1f6c-8860-c617-a803-b187b491568e"
}
}
};
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/vnd.urbanairship+json; version=3;" forHTTPHeaderField:@"Accept"];
NSString *authStr = [NSString stringWithFormat:@"%@:%@", appKey, appMasterSecret];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed]];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:push
options:0 // Pass 0 if you don't care about the readability of the generated string
error:NULL];
request.HTTPBody = jsonData;
[NSURLConnection connectionWithRequest:request delegate:self];
}
And The Response:
- (void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *) response {
NSHTTPURLResponse * res = (NSHTTPURLResponse *) response;
NSLog(@"response: %@",res);
NSLog(@"res %li\n",(long)res.statusCode);
if (res.statusCode == 202) {
//Show Alert Message Sent
}else{
//Handle Error
}
}
