Android Question Using windows Curl command line utility for send Firebase notifications

[Wolodymyr]

Hi for all
Erel's b4j-sendingtool-zip working great, but may be anybody know way to use CURL (already built in installed in windows 10) to send such messages?

I cannot found ready to use guide to build command line parameters for CURL yet. We must use only 4 incoming parameters: API_KEY (firebase server key for your project), topic name, title and body.

Firebase push Notifications Php stopped working

Main problem was because JSON part must use double quotes as special symbols like <\">, so simplest method is to use external file with ready to use JSON part
Example for sending messages by topic name "general". Launching b4j-sendingtool take about two seconds to arrive messages, CURL - about one second
curl -H "Content-type: application/json;charset=UTF-8" -H "Authorization:key=<CHANGE-TO-YOURS-FIREBASE-SERVER-KEY>" -X POST -d @jsondata.txt https://fcm.googleapis.com/fcm/send

{"data":{"title":"CURL test","body":"CURL sending is working!!"},"to":"\/topics\/general"}
