How to check or convert to JSON datatype?

Question

I am using python elastic search client to query an elastic search instance and following an example on how to use it. I ran the code below and got nothing back for the query I'm trying to run.

In the for loop below, how can I check the count or what kind of response I'm getting back from elasticsearch, while iterating over results['hits']['hits'] ? Is there a way to convert this to a JSON array?

newResults= []

results = es_client(index="sampleindex", doc_type="sampledoc",
                    body={"query": {"match": {"text":sometext}}})
for i, hit in enumerate(results['hits']['hits']):
    newResults.append(hit[i][_id])
    print("%s) %s" % (doc['_id'], doc['_source']['content']))

results

{
    "took": 0,
    "timed_out": false,
    "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 122,
        "max_score": 1.0,
        "hits": [{
                "_index": "someindex",
                "_type": "doc",
                "_id": "1",
                "_score": 1.0,
                "_source": {
                    "Name": "amazon"
                }
            },
            {
                "_index": "someindex",
                "_type": "doc",
                "_id": "2",
                "_score": 1.0,
                "_source": {
                    "Name": "alibaba"
                }
            }
        ]
    }
}

Answer 1

Essentially, a JSON array is a dictionary which include a list of pair matching a key to a value. To do a conversion to a JSON array, think of it like converting to a list of paired elements.

Answer 2

Here are one JSON example:

{ "student": {name : "Chris", email: "chris@email.net"}  }

Student would be the key. And the rest of the information would be the value, which in turn is a list of key-value pair.

Answer 3

Below is code showing how to use the built-in json module to convert the data in the results string into a Python data structure and then display some of its contents.

import json

#results = es_client(index="sampleindex", doc_type="sampledoc",
#                    body={"query": {"match": {"text":sometext}}})

results = '''
{
    "took": 0,
    "timed_out": false,
    "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 122,
        "max_score": 1.0,
        "hits": [{
                "_index": "someindex",
                "_type": "doc",
                "_id": "1",
                "_score": 1.0,
                "_source": {
                    "Name": "amazon"
                }
            },
            {
                "_index": "someindex",
                "_type": "doc",
                "_id": "2",
                "_score": 1.0,
                "_source": {
                    "Name": "alibaba"
                }
            }
        ]
    }
}
'''


results = json.loads(results)  # Deserialize results into Python object.
print(f"There were {len(results['hits']['hits'])} hits:")
print()
for i, hit in enumerate(results['hits']['hits']):
    print(f'hit[{i}]: {json.dumps(hit, indent=4)}')

Output:

There were 2 hits:

hit[0]: {
    "_index": "someindex",
    "_type": "doc",
    "_id": "1",
    "_score": 1.0,
    "_source": {
        "Name": "amazon"
    }
}
hit[1]: {
    "_index": "someindex",
    "_type": "doc",
    "_id": "2",
    "_score": 1.0,
    "_source": {
        "Name": "alibaba"
    }
}
