Question

我正在研究一个简单的原型，需要测试从一个设备向另一个设备发送推送通知。

我已通过电子邮件发送Urban Airship为我的应用程序启用“允许从设备推送” - 他们确实打开了它。

我正在尝试使用NSURLConnection从设备发送推送通知。

这是我的代码：

- (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);
}

其他人成功完成了这项工作吗？

Answer 1

看看Urban Airship的guide to troubleshooting HTTP status codes和documentation for the push API，我的猜测是你需要在网址上添加一个斜杠：

[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]

使用V3 API的示例...

-(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];

}

响应：

- (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

}

}
