im using python3 and tornado to send a JSON using a HTTP POST request, like this.
Server.py
@gen.coroutine
def getResponseWS(self, url, contentBody, method='POST'):
import tornado.ioloop
import tornado.web
import tornado.options
from tornado import gen
from tornado.httpclient import HTTPClient
from tornado.escape import json_decode, json_encode
import json
http_client = tornado.httpclient.AsyncHTTPClient()
headers = {
'Content-Type': 'application/json; charset=UTF-8'
}
simplejson = json.dumps(contentBody)
#-------------------------------------------
# contentBody = {"some_key": "some_value"}
# url = 'http://some_ip_address:8088/testService'
#
baseLogger.info("Data to be send to webservice:%s" % simplejson)
try:
request = tornado.httpclient.HTTPRequest(url=url, method=method, headers=headers, body=simplejson)
response = yield http_client.fetch(request)
print("-------SERVICE RESPONSE-----------")
print(response)
except Exception as e:
baseLogger.info("SERVICE RESPONSE:%s" % e)
contentJson = {}
I dont know why it not work, i try the same request on postman and it works perfect and trying the code i get this response:
Console
11-08 16:14:01 BaseLogger :INFO IP:[127.0.0.1] -Data to be send to webservice:{"some_key": "some_value"}
-------SERVICE RESPONSE-----------
HTTPResponse(_body=None,buffer=<_io.BytesIO object at 0x7fda25fad048>,code=200,effective_url='http://some_ip_address:8088/testService',error=None,headers=<tornado.httputil.HTTPHeaders object at 0x7fda45a9d160>,reason='OK',request=<tornado.httpclient.HTTPRequest object at 0x7fda25f7db38>,request_time=0.8046760559082031,time_info={})
It seems to be working right, but the response should be a json, not that.
It looks to me like everything worked. HTTPResponse is an object with attributes like headers and body, but its string form is not very friendly. You probably want to print(response.body) instead of the response object itself. Then you'll see the server response, which you can parse with json.loads(response.body).
