I want to post data of one influxdb to another using http.post, but its not working. i am using Task to do it.Here is my code below. I could not use To function because of data diode limitation. Please help

import “json”  
import “http”  
import “array”

option task = {  
name: “TTEST”,  
every: 10s,  
}

lastReported = from(bucket: “RTR”)  
|\> range(start: -1m)  
|\> filter(fn: (r) =\> r.\_measurement == “cpu”)  
|\> yield(name: “last”)  
|\> findColumn(fn: (key) =\> true, column: “\_value”)

http.post(  
url: “[http://localhost:8086/api/v2/write/?orgID=73b2e92f943063f3&bucket=ANK&precision=ns](http://localhost:8086/api/v2/write/?orgID=73b2e92f943063f3&bucket=ANK&precision=ns)”,  
headers: {  
Authorization: “Bearer Lx0FOdmHOxkOM\_wMxpMPvCiJXVsUdhv3DbHqzS6CSUT9yTUmoUEl0sfoJMnykFAafjOAtLNg-wV-tln7gk2LPA==”,  
“Content-type”: “application/json”,  
},  
data: json.encode(v: lastReported),  
)

The `write` endpoint requires data in the [line protocol format](https://docs.influxdata.com/influxdb/v2.2/write-data/developer-tools/api/), not JSON.

Thanks Vlasta…now its working

import “http”

option task = {  
name: “TTEST”,  
every: 1m,  
}

lastReported = from(bucket: “RTR”)  
|\> range(start: -1m)  
|\> filter(fn: (r) =\> r[“\_measurement”] == “cpu”)  
|\> filter(fn: (r) =\> r[“\_field”] == “usage\_user”)  
|\> filter(fn: (r) =\> r[“cpu”] == “cpu-total”)  
|\> yield(name: “last”)  
|\> findColumn(fn: (key) =\> true, column: “\_value”)

http.post(  
url: “[http://localhost:8086/api/v2/write/?org=XXXX&bucket=A5&precision=ns](http://localhost:8086/api/v2/write/?org=XXXX&bucket=A5&precision=ns)”,

data: bytes(v: “mem,host=host1 used\_percent=” + string(v: lastReported[0])),  
)

Hello @aceankit99,  
I believe that http.post() you can only send one value at a time:  
You’d have to do something like:

```auto
lastReported[0]

```

Or you’d have to use the reduce function to create a json object. Something like:

```auto
import "json"
import "http"
import "array"

lastReported = from(bucket: "engineering's Bucket") |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r["_measurement"] == "CBBandwidthAlert")
  |> filter(fn: (r) => r["_field"] == "code")
  |> group()
  |> map(fn: (r) => ({ r with index: 1 })) 
  |> cumulativeSum(columns: ["index"])
  |> map(fn: (r) => ({ r with gindex: r.index / 250 })) 
  |> group(columns: ["gindex"])
  |> reduce(
    fn: (r, accumulator) => ({ _value:accumulator._value + "\"" + r.host + "\","}),
    identity: {_value: "{hosts:["}
  )
  |> map(fn: (r) => ({ r with _value: r._value + "]}" }))
  |> yield()

```

@aceankit99  
Of course! Out of curiosity what are you doing with InfluxDB? I’m curious to learn about what community is doing.

I am working on an IOT solution where we have to pass data from one influx instance to another influx instance through OPDS 1000
