Question

I’m having a difficulty trying to make a Python REST POST to a webservice running on Glassfish. I have verified that POST works ok using CURL but having no luck with Python.

Here is the CURL request that works ok.

curl -X POST -H "Content-Type: application/json" -d '{"id":1,"lastname":"smith"}' 
  http://192.168.0.20:8080/field1/resources/com.field1entity.field1

Here is the Python code to make the POST request

import urllib
import httplib2

def call():
http = httplib2.Http()

url = 'http://192.168.0.20:8080/field1/resources/com.field1entity.field1'

params = urllib.urlencode({"id":11111,"lastname":"oojamalip"})

response, content = http.request(url, 'POST', params, headers={'Content-type':'application/json'})
print "lets stop here to have a looksy at the variables"                               
print content

if __name__ == '__main__':

namesPage = call()
print namesPage

Output from console,

Unexpected character (‘l’ (code 108)): expected a valid value (number, String, array, object, ‘true’, ‘false’ or ‘null’)

Hope someone can shed some light on the problem.

thanks

Answer 1

You are url encoding the prams and then telling the server it is json encoded

import json

params = json.dumps({"id":11111,"lastname":"oojamalip"})
# then
response, content = http.request(url, 'POST', body=params, headers={'Content-type':'application/json'})
