[英]Send message to topic - Firebase iOS
我想从我的客户端应用程序向使用 Firebase 订阅特定主题的其他设备发送消息。 Firebase 文档告诉我如何发送此请求以部署此消息:
主题 HTTP POST 请求发送到单个主题:
https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA
{
"to" : /topics/foo-bar",
"priority" : "high",
"notification" : {
"body" : "This is a Firebase Cloud Messaging Topic Message!",
"title" : "FCM Message",
}
}
我不知道如何在我的代码中实现这一点,我尝试过但没有成功,这是我的代码:
NSDictionary *dic1 = @{
@"body : " : @"This is a Firebase Cloud Messaging Topic Message",
@"title : " : @"FCM Message"
};
NSDictionary *dic2 = @{
@"to : " : @"/topics/news",
@"priority : " : @"high",
@"notification : " : dic1
};
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"https://fcm.googleapis.com/fcm/send"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"key=MYKEY" forHTTPHeaderField:@"Authorization"];
NSError *error;
[request setHTTPBody:[NSJSONSerialization dataWithJSONObject:dic1 options:NSJSONWritingPrettyPrinted error:&error]];
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
请帮忙。 谢谢
我找到了问题的解决方案。
正确的代码如下:
NSDictionary *dic1 = @{
@"body" : @"This is a Firebase Cloud Messaging Topic Message",
@"title" : @"FCM Message"
};
NSDictionary *dic2 = @{
@"to" : @"/topics/news",
@"priority" : @"high",
@"notification" : dic1
};
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"https://fcm.googleapis.com/fcm/send"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"key=YOURKEY" forHTTPHeaderField:@"Authorization"];
NSError *error;
[request setHTTPBody:[NSJSONSerialization dataWithJSONObject:dic2 options:NSJSONWritingPrettyPrinted error:&error]];
[[[NSURLSession sharedSession] dataTaskWithRequest:request] resume];
我希望这将有助于将来解决这个问题的任何人。
发送主题通知的方法
class PushNotificationSender {
public static let shared = PushNotificationSender()
func sendPushNotification(to token: String, title: String, body: String) {
let urlString = "https://fcm.googleapis.com/fcm/send"
let url = NSURL(string: urlString)!
let paramString: [String : Any] = ["to" : "/topics/Post",
"notification" : ["title" : title, "body" : body],
"data" : ["user" : "test_id"]
]
let request = NSMutableURLRequest(url: url as URL)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject:paramString, options: [.prettyPrinted])
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("key= set your server key find from your firbase cloud messging setting", forHTTPHeaderField: "Authorization")
let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) in
do {
if let jsonData = data {
if let jsonDataDict = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: AnyObject] {
NSLog("Received data:\n\(jsonDataDict))")
}
}
} catch let err as NSError {
print(err.debugDescription)
}
}
task.resume()
}
}
用法
PushNotificationSender.shared.sendPushNotification(to: "" , title: fullName , body: textView.text)
