带有python字典的REST API请求正文

Question

I am working with AWS REST API. I am trying to invoke glue job via REST API. For that, I need to pass arguments as JSON object. And withing this json object, I should pass python dictionary as JSON value. This is the request body,

   {
    "Arguments":{
    "jobParameter":"{
  'key1':'keyname=subvalue',
  'key2':'value2'
}"

},
    "JobName":"jobname"
    }

python dictionary = { 'key1':'keyname=subvalue', 'key2':'value2' }

When I test the API by giving this as input, it gives an error,

{ "__type": "SerializationException" }

Please can anyone help with this?

Answer 1

I think it's not recognizing as a valid JSON. Try send something diferente as parameter of jobParameter to test.

Answer 2

This problem often occur when a json item has as value another dict. Another solution is to pass it as a json.dumps()

import json
body = {
    "Arguments":{
    "jobParameter":{
        'key1':'keyname=subvalue',
        'key2':'value2'
        }    
    },
    "JobName":"jobname"
    }
body_parsed = json.dumps(body)

then in your request, you should do:

requests.post(url=url, body=body_parsed , headers=headers)
