Parse sent data with raw http request error

[chesha1]

Describe the bug
When sending logs with direct http request to loki in grafana cloud, it seems that loki didn't parse data correctly.

To Reproduce
The endpoint looks like https://123:glc_eyJ@logs-prod-020.grafana.net/loki/api/v1/push

The http header Content-Type is set application/json

The request body is below, it is directly copied from official documents

{
	"streams": [
		{
			"stream": {
				"label": "value"
			},
			"values": [
				[
					"2024-05-08T18:52:26.164724+08:00",
					"{\"level\":\"info\",\"message\":\"Hello world!\"}"
				],
				[
					"2024-05-08T18:52:26.164724+08:00",
					"{\"level\":\"info\",\"message\":\"Hello world!\"}"
				]
			]
		}
	]
}

There is a curl version:

curl --request POST \
  --url https://787766:glc_ey@logs-prod-020.grafana.net/loki/api/v1/push \
  --header 'Content-Type: application/json' \
  --data '{
	"streams": [
		{
			"stream": {
				"label": "value"
			},
			"values": [
				[
					"2024-05-08T18:52:26.164724+08:00",
					"{\"level\":\"info\",\"message\":\"Hello world!\"}"
				],
				[
					"2024-05-08T18:52:26.164724+08:00",
					"{\"level\":\"info\",\"message\":\"Hello world!\"}"
				]
			]
		}
	]
}'

The response is:

loghttp.PushRequest.Streams: []loghttp.LogProtoStream: unmarshalerDecoder: Value looks like Number/Boolean/None, but can't find its end: ',' or '}' symbol, error found in #10 byte of ...|]
			]
		}
	]
}|..., bigger context ...|fo\",\"message\":\"Hello world!\"}"
				]
			]
		}
	]
}|...

Hello!

The timestamp, as mentioned in the document you referenced, needs to be in nanoseconds, so something along the lines of 1715165546164724000 for 2024-05-08T18:52:26.164724+08:00.

As such, I was able to issue your command using my local install after making this adjustment:

curl --request POST \
  --url http://localhost:3100/loki/api/v1/push \
  --header 'Content-Type: application/json' \
  --data '{
	"streams": [
		{
			"stream": {
				"label": "value"
			},
			"values": [
				[
					"1715313600000000000",
					"{\"level\":\"info\",\"message\":\"Hello world2!\"}"
				],
				[
					"1715313600000000000",
					"{\"level\":\"info\",\"message\":\"Hello world!\"}"
				]
			]
		}
	]
}'

Thank you very much for reply, it now works.

But I have another problem, no logs can be found in grafana cloud, could you check this? #12935
