HTTP Upload¶

Configure URL, request method, Header, Body template through code in custom quick functions.

Example Code

# data=[{"name": "ED002092", "health": 1, "timestamp": 1773107297, "timestampMsec": 1773107297383, "measures": [{"name": "pl", "health": 1, "timestamp": 1773107293, "timestampMsec": 1773107293724, "value": 49.960000000000001}]}]

import json
import ssl
from common.Logger import logger
from quickfaas.measure import recall
from http.client import HTTPConnection
from http.client import HTTPException
from http.client import HTTPSConnection

def http(params, variables):
    paramsn=[]
    for i in params:
        dev={"name":i["name"],"health":i["health"],"timestamp":i["timestamp"],"measures":[]}
        for j in i["measures"]:
            dev["measures"].append({"name":j["name"],"health":j["health"],"timestamp":j["timestamp"],"value":j["value"]})
        paramsn.append(dev)
    logger.info(f'http request parameter:{paramsn}')
    try:
        url = variables["url"]
        port = variables["port"]
        h1 = HTTPSConnection(host=url, port=port, context=ssl.SSLContext(),timeout=3)
        if variables["schema"] == "http":
            h1 = HTTPConnection(host=url, port=port)
        body = json.dumps(paramsn)
        logger.info(f'Send HttpBody --> {body}')
        headers = {"Content-Type": "application/json", "x-api-key": variables["x-api-key"]}
        h1.request(method="POST", url=variables["path"], body=body, headers=headers)
        result = h1.getresponse().read()
        h1.close()
        logger.debug(f'http reponse is :{str(result, "UTF-8")}')
    except HTTPException as err:
        logger.error(f'http error:{err}')

def main():
    logger.info("Report measure to platform pass http start")
    variables = {
        "schema":       "http",
        "url":          "***.***.***.***",
