CouchDB Query View with Multiple Keys Formatting

couchdbkeyviews

I'm having a problem getting a couchdb view to return the proper documents when using multiple keys.

This works fine, returning the documents that match:

GET http://example.com:5984/myDb/_design/myFilters/_view/getItemByForeignKeyId?key=abc123

This returns returns all documents in the view, matching or not:

GET http://example.com:5984/myDb/_design/myFilters/_view/getItemByForeignKeyId?keys=%5B%22abc123%22%5D

I'm usually very good at hunting down my answers. But, CouchDB documentation is very clear on the format for using multiple keys. I've seen some use the ?keys=[123,123] and i've also seen ?keys="abc","abc".

If anyone can offer any clarification on the 'proper' format and encoding of multiple key queries for CouchDB using a GET method, I would be extremely appreciative.

To get multiple keys from a view, you need to do a post request and submit the keys in the request body. Your HTTP request will look like this:

POST /myDb/_design/myFilters/_view/getItemByForeignKeyId
Content-Type: application/json

{
   "keys" : [
      "abc",
      "123"
   ]
}
