issues while posting data from curl to Firestore throw curl - firebase

Question

I am very beginner to Google Firestore (also to Firebase). I am doing a simple POC and I am suffering a bit to interact with FireStore. Well, reading the data from Angular worked as a charm so easy. Nevertheless, simple actions like add a new data from curl or deleting the collection from FireBase Cli has taken me the whole day without progress . Just to stress how dummy I am in FireStore, I have used ElasticSearch local installed so I am trying similar behaviours/tools/functionalities like posting/creating fields from curl/postman (it is not part of this question compare one another, just exposing my limitations) but I just can't move forward.
This is how I connected successfully from Angular:
firebaseConfig : {
apiKey: "*** removed ***",
authDomain: "transfer-status-realtime.firebaseapp.com",
databaseURL: "https://transfer-status-realtime.firebaseio.com",
projectId: "transfer-status-realtime",
storageBucket: "transfer-status-realtime.appspot.com",
messagingSenderId: "143612370857",
appId: "1:143612370857:web:a9d0b21e3a58520ed02eb8",
measurementId: "G-WT5C346D7T"
}
I have based mainly my tentatives in Making Rest Calls and other stack overflow question
My last and recent tried:
c:\temp>curl -X POST -H "Content-Type: application/json" -d'{"fields": {"status": "success"}}' "https://firestore.googleapis.com/v1beta1/projects/transfer-status-realtime/databases/(default)/documents/transfers?&key=***removed***"
curl: (3) [globbing] unmatched brace in column 1
curl: (3) [globbing] unmatched close brace/bracket in column 8
{
"error": {
"code": 400,
"message": "Invalid JSON payload received. Closing quote expected in string.\n\n^",
"status": "INVALID_ARGUMENT"
}
}
So my main issue: how add data to FireStore from curl?
In case it matter, here is my database console:
Other tentatives probably in wrong direction I have tried are:
According to https://firebase.google.com/docs/database/rest/save-data, I can save fields by using PUT so I tried write a curl command and I got stuck because I don't know what would be the "fireblog" in my case?
curl -X PUT -d '{
"transfers": {
"id": "idfromPut",
"status": 1
}
}' 'https://transfer-status-realtime.firebaseio.com/rest/saving-data/fireblog/users.json'
I also tried but what would be message_list in my case?
curl -X POST -d '{"status" : 2}' 'https://transfer-status-realtime.firebaseio.com/message_list.json'

c:\temp>curl -X POST -H "Content-Type: application/json" -d "{\"fields\": {\"status\": \"success\"}}" "https://firestore.googleapis.com/v1/projects/transfer-status-realtime/databases/(default)/documents/transfers?&key=*** removed ***"
{
"error": {
"code": 400,
"message": "Invalid value at 'document.fields[0].value' (type.googleapis.com/google.firestore.v1.Value), \"success\"",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"field": "document.fields[0].value",
"description": "Invalid value at 'document.fields[0].value' (type.googleapis.com/google.firestore.v1.Value), \"success\""
}
]
}
]
}
}
In case it is relevant, same issue using external json file
C:\WSs\reactive-stack\reactive-front\src>curl -X POST -H "Content-Type: application/json" -d #load-data-tofirestore.json "https://firestore.googleapis.com/v1/projects/transfer-status-realtime/databases/(default)/documents/transfers?&key=***removed"
{
"error": {
"code": 400,
"message": "Invalid value at 'document.fields[0].value' (type.googleapis.com/google.firestore.v1.Value), \"success\"",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"field": "document.fields[0].value",
"description": "Invalid value at 'document.fields[0].value' (type.googleapis.com/google.firestore.v1.Value), \"success\""
}
]
}
]
}
}
And here is the json file
{"fields": {"status": "success"}}
* SOLUTION *
from cUrl
C:\WSs\reactive-stack\reactive-front\src>curl -H "Content-Type: application/json" -X POST https://firestore.googleapis.com/v1/projects/transfer-status-realtime/databases/(default)/documents/transfers -d "{\"fields\": { \"status\": { \"stringValue\": \"outro status\" } }}"
{
"name": "projects/transfer-status-realtime/databases/(default)/documents/transfers/ddwHxjy7eQV3640pW0Xx",
"fields": {
"status": {
"stringValue": "outro status"
}
},
"createTime": "2020-04-06T16:21:16.453553Z",
"updateTime": "2020-04-06T16:21:16.453553Z"
}
from PowerShell
PS C:\Users> $body = #"
>> {
>> "fields": {
>> "status": {
>> "stringValue": "fracasso"
>> }
>> }
>> }
>> "#
>>
PS C:\Users\Cast> $params = #{

PS C:\Users\Cast> Invoke-RestMethod #params

I believe the root cause of your issue is due to cURL on a windows system. As seen in this other question, there are limitations on how the command line arguments are parsed in a windows shell.
Instead of using this:
-d'{"fields": {"status": "success"}}'
You should state your payload as:
-d "{\"fields\": {\"status\": \"success\"}}"
Another solution could be writing the JSON in a file and using its path in the cURL query. I believe you could keep the right JSON format this way, but you would be forced to use a file, which is far from optimal if you don't intend to send the same payload multiple times:
-d #file_with_data.json
