Firebase从设备发送推送通知（IOS）

问题描述：

在ios中，我使用的是Firebase数据库和FCM。我必须通过设备令牌从设备发送推送通知给设备。我有FCM API“https://fcm.googleapis.com/fcm/send”这是POST方法，并添加参数像：Firebase从设备发送推送通知（IOS）

Content-Type:application/json 
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA 

{ 
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...", 
    "data" : { 
    ... 
    }, 
}

，但是当我尝试调用这个API这常是返回我一个错误，而同样API从Android设备调用，这是在Android的工作，而不是在IOS这里是我的代码和错误，请给我解决

-(void)sendPush 
{ 



    NSDictionary *noti = @{@"body": @"This is a Firebase Cloud Messaging Topic Message", @"title": @"high"}; 
    NSDictionary *data = @{@"text": @"This is a Firebase Cloud Messaging Topic Message", @"title": @"high"}; 
    NSDictionary *params = @{@"to": @"dbpuoXnzY3o:APA91bH3AE_XCbsLpOXycNULcSh1GHzohEFdopmzkY_n8bm78E9_5fHyY3PLCwi5HtTLU_IoOwfdbDc5qCbyzc6tD9Ahg0EviCfbAmhftmMsPqfi0WC...",@"notification":noti,@"data":data}; 
    NSLog(@"%@",params); 

    [NetworkManager postNotification:params getUrl:@"https://fcm.googleapis.com/fcm/send" success:^(id response) { 
     NSLog(@"%@",response); 



    } failure:^(NSError *error) { 

    }]; 

}

中的NSLog它看上去是这样

{ 
    data =  { 
     text = "This is a Firebase Cloud Messaging Topic Message"; 
     title = high; 
    }; 
    notification =  { 
     body = "This is a Firebase Cloud Messaging Topic Message"; 
     title = high; 
    }; 
    to = "dbpuoXnzY3o:APA91bH3AE_XCbsLpOXycNULcSh1GHzohEFdopmzkY_n8bm78E9_5fHyY3PLCwi5HtTLU_IoOwfdbDc5qCbyzc6tD9Ahg0EviCfbAmhftmMsPqfi0WC..."; 
}

Afnetworking调用函数

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 


    manager.responseSerializer = [AFJSONResponseSerializer 
            serializerWithReadingOptions:NSJSONReadingAllowFragments]; 
    // [manager.requestSerializer setValue:@"text/html" forHTTPHeaderField:@"Content-Type"]; 
    [manager.requestSerializer setValue:@"AIzaSyADxgFPrxx....." forHTTPHeaderField:@"key"]; 

    // NSLog(@"Token==%@",[GeneralSetting sharedInstance].token_number); 
    [manager POST:URL parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { 
     [MBProgressHUD hideHUDForView:appDelegate.window animated:YES]; 
     success(responseObject); 

     ////NSLog(@"success!"); 
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { 
     failure(error); 
     [MBProgressHUD hideHUDForView:appDelegate.window animated:YES]; 
     NSLog(@"error: %@", error.description); 

     // [self alert:@"" title:@""]; 
    }];

错误是

error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: unauthorized (401)" UserInfo={NSUnderlyingError=0x17024a1d0 {Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x17402fa40> { URL: https://fcm.googleapis.com/fcm/send } { status code: 401, headers { 
    "Cache-Control" = "private, max-age=0"; 
    "Content-Encoding" = gzip; 
    "Content-Length" = 259; 
    "Content-Type" = "text/html; charset=UTF-8"; 
    Date = "Tue, 04 Jul 2017 10:17:43 GMT"; 
    Expires = "Tue, 04 Jul 2017 10:17:43 GMT"; 
    Server = GSE; 
    "alt-svc" = "quic=\":443\"; ma=2592000; v=\"39,38,37,36,35\""; 
    "x-content-type-options" = nosniff; 
    "x-frame-options" = SAMEORIGIN; 
    "x-xss-protection" = "1; mode=block"; 
} },

请帮助我，请给我解决

这是从邮递员的工作我从邮递员试图

我发送的是同样的数据从代码荷兰国际集团，这是不工作可能是问题正在发送词典我使用这个代码

NSDictionary *noti = @{@"body": @"Hello", @"title": @"This is test message"}; 

    NSDictionary *params = @{@"to": [GeneralSetting sharedInstance].token_number,@"notification":noti}; 
    NSLog(@"%@",params);

和

[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
    [manager.requestSerializer setValue:@"key=AIzaSy.....tBxdYAIRp2KBG0NoS8dOqgy4" forHTTPHeaderField:@"Authorization"];

的响应

{ 
    notification =  { 
     body = Hello; 
     title = "This is test message"; 
    }; 
    to = "dQgCDOK3sec:APA91zFbkqkgyTNrsYsEmUJwpCtMs1VAmXF9DpF_zQfBYui3UjCA9nYtS_TK549RPnlWEfe-jSvD9MMc3lTFNsGJlyIOqNm84s8GoW1LfTGG0geuWEclb"; 
} 

Request failed: bad request (400)

你跟邮递员检查？这是工作的API？ – user3589771

我不知道邮递员，我必须尝试从FCM控件发送推送，设备从设备令牌推送 –

内容类型必需'acceptableContentTypes = application/json'。你在顶部提到。你的错误显示你只是设置内容类型'“Content-Type”=“text/html; charset = UTF-8”;' – user3589771

答

您可以：

1）允许您的应用接受text/html数据：

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"]; 
// OR 
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

2）或更高，改变你的数据类型，所以它是application/json为@ user3589771提及。

确保AFHTTPSessionManager正确格式化JSON与AFJSONRequestSerializer
