问题
I am working through the tutorial on setting up Cloud Messaging. I followed the instructions in the video on the page https://firebase.google.com/docs/cloud-messaging/js/client?authuser=0 when I try to send the curl command I get a strange error. I have read the Cloud Messaging quickstart as well as a few other pages trying to solve the error, but to no avail.
The command I entered on the command line is:
curl --header "Authorization: key=AIzaSyCFCmFwwWV53PqV2M-NUZyp6lYSz43tUiQ" --header "Content-Type: application/json" -d '{"to": "di6GZyDevbI:APA91bFhNMiuJaMIE3IQL2NurPCWBhCtzculj5uvx-on121Z0UczJ0FyiiQbaRFvGqNs3bmq084vQ-z-8vF_GZQ5J-QCBrWgp4_saWSwTXytZmScNbPLGRkOQns_QgETStDTmLJwixI1", "notification": { "title": "Hello", "body": "World", "icon": "/firebase_logo.png" }}' https://fcm.googleapis.com/fcm/send
The result is:
curl: (3) Port number ended with 'A'
curl: (6) Could not resolve host: notification
curl: (3) [globbing] unmatched brace in column 1
curl: (6) Could not resolve host: title
curl: (6) Could not resolve host: Hello,
curl: (6) Could not resolve host: body
curl: (6) Could not resolve host: World,
curl: (6) Could not resolve host: icon
curl: (3) <url> malformed
curl: (3) [globbing] unmatched close brace/bracket in column 1
JSON_PARSING_ERROR: Unexpected character (') at position 0.

The issue was with the quotes on the windows command line. After replacing the single quotes with double quotes and escaping the inner quotes it works, like so:
curl -X POST -H "Authorization: key=AAAAATYbVMw:APA91bFAEaRl8bZPgWGNGA7BCP22y_OLIlHevfUjEXEEklDav1sOwcxiFiFin625JsdaWJBAF06-U1Ey9-mhz6f2Es9-ztOeXpco6_AkvIbEO4dbe2LnI_JVw-W7mqOT5KeSn23y4b1h" -H "Content-Type: application/json" -d "{\"to\": \"di6GZyDevbI:APA91bFhNMiuJaMIE3IQL2NurPCWBhCtzculj5uvx-on121Z0UczJ0FyiiQbaRFvGqNs3bmq084vQ-z-8vF_GZQ5J-QCBrWgp4_saWSwTXytZmScNbPLGRkOQns_QgETStDTmLJwixI1\", \"notification\": { \"title\": \"Hello\", \"body\": \"World\", \"icon\": \"/firebase_logo.png\" }}" "https://fcm.googleapis.com/fcm/send"
Produces the expected result:
{"multicast_id":5167616001901538265,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1530306327290339%e609af1cf9fd7ecd"}]}
