Send json data for json get request in odoo 12 - json

Question

I want send json data from odoo controller.For that i have created below controller
from odoo.http import Response
import json
#http.route('/api/json_get_request',auth='public',type='json',methods=["GET"],csrf=False)
def printjson(self,**kw):
headers={'content-type':'application/json'}
return Response(json.dumps({"test":"json string"}),headers=headers)
but accessing http://localhost:8089/api/json_get_request in postman gives me Invalid json data then I have check postman console in that response header -> Content-Type: "text/html" is shown.
Not understand after sending data in the json type why json data not recieved.
After accessing http://localhost:8089/api/json_get_request as http request on postman gives me correct json data.
Please give me suggestion
Thanks in advance

Answer 1

First thing method that handle 'json' request should return a dictionary directly:
#http.route('/api/json_get_request', auth='public', type='json', csrf=False)
def printjson(self, **kw):
return {'attribute': 'test'}
this will return a result like this:
{
"jsonrpc": "2.0",
"id": null,
"result": {
"attribute": "test"
}
}
You are having this error because you didn't send any json data with the request.
You could test your code using the requests module:
>>> import requests
>>> import json
>>> url = 'http://localhost:8069/api/json_get_request'
>>> data = {'params': {'test': 100}}
>>> headers={'content-type':'application/json'}
>>> requests.get(url, data=json.dumps(data), headers=headers)
<Response [404]>
It gives me this error because there is no database selected, and I have more than one database.
If you have only one database you see the correct result.
but when you test it from Postman extension I used RESTED
Because I'm all ready logged to Odoo the method was executed successfully , Just look for a better postman extension or search how to send json data with your current postman. You need to send some json data in the request.
