通过python`request`代码将树莓派传感器数据发送到远程elasticsearch

Question

Sensor Data --> Raspberry Pi --- (send sensors data via requests Python Code) ---> remote server (Elasticsearch)

Target is sending received sensor data to elasticsearch via request python module.

Question: When I use this code: data = '{"TempA":"23"}' , the post request work and document of elasticsearch is being updated as shown below:

{"_index":"report","_type":"_doc",{"TempA":"23"}

But when I changed the code to: data = {"TempA": mens} , to get value of sensor directly, it does not work and document of elasticsearch does not update. (This is my python code which receives data from sensor and put the value of sensor in "mens".)

#!/usr/bin/env python3

import time
from SX127x.LoRa import *
from SX127x.board_config import BOARD
import requests

BOARD.setup()
BOARD.reset()
headers = {
    'Content-Type': 'application/json',
}

class mylora(LoRa):

    def __init__(self, verbose=False):
        super(mylora, self).__init__(verbose)
        self.set_mode(MODE.SLEEP)
        self.set_dio_mapping([0] * 6)

    def on_rx_done(self):
        self.clear_irq_flags(RxDone=1)
        payload = self.read_payload(nocheck=True)
        mens=bytes(payload).decode("utf-8",'ignore')
        print(mens)
        data = {"TempA":mens}
        response = requests.post('http://192.168.100.125:9200/report/_doc/customer505', headers=headers, data=data)
        time.sleep(2)
        self.reset_ptr_rx()
        self.set_mode(MODE.RXCONT)

    def start(self):
        while True:
            self.reset_ptr_rx()
            self.set_mode(MODE.RXCONT) # Receiver mode
            while True:
                pass;

Thanks for comments. After some googling, I found the solution. The key point was json=params and params instead of data . Changes are as below:

#!/usr/bin/env python3

import time
from SX127x.LoRa import *
from SX127x.board_config import BOARD
import requests
import json

BOARD.setup()
BOARD.reset()
headers = {
    'Content-Type': 'application/json',
}

class mylora(LoRa):

    def __init__(self, verbose=False):
        super(mylora, self).__init__(verbose)
        self.set_mode(MODE.SLEEP)
        self.set_dio_mapping([0] * 6)

    def on_rx_done(self):
        self.clear_irq_flags(RxDone=1)
        payload = self.read_payload(nocheck=True)
        mens=bytes(payload).decode("utf-8",'ignore')
        print(mens)
        url = 'http://192.168.100.125:9200/report/_doc/customer600'
        params = {'soilA': mens, 'customer_id': 'customer600'}
        r = requests.post(url, headers=headers, json=params)
        time.sleep(2)
        self.reset_ptr_rx()
        self.set_mode(MODE.RXCONT)
