mget() does not accept ids as parameter

[schettino72]

Elasticsearch version (bin/elasticsearch --version): 7.16.2

elasticsearch-py version (elasticsearch.__versionstr__): 7.16.2

Description of the problem including expected versus actual behavior:

Expected to be able to pass body field as top-level parameter.
But not available to mget().

Steps to reproduce:

import elasticsearch
es = elasticsearch.Elasticsearch()
es.mget(index='my_index', body={'ids':[8, 69]}) # works fine
es.mget(index='my_index', ids=[8, 69]) # raises exception

Exception:

TypeError                                 Traceback (most recent call last)
<ipython-input-21-df136b3e844f> in <module>
----> 1 es.mget(index='vendor_1', ids=[8, 69])

~/.virtualenvs/xxx/lib/python3.8/site-packages/elasticsearch/client/utils.py in _wrapped(*args, **kwargs)
    345                 if p in kwargs:
    346                     params[p] = kwargs.pop(p)
--> 347             return func(*args, params=params, headers=headers, **kwargs)
    348 
    349         return _wrapped

TypeError: mget() got an unexpected keyword argument 'ids'

In 7.x only a subset of APIs support passing body fields as parameters. Those APIs are listed in the issue under the "which APIs are affected" section:

• search
• index
• create
• update
• scroll
• clear_scroll
• search_mvt
• indices.create

Other APIs like mget you'll have to use body={...} until you upgrade to v8.0.0 of the client library. There are currently alpha releases out if you're interested in trying them out.

Does this resolve your issue?
