1.4.1. /db/doc
HEAD
/{db}/{docid}
Returns the HTTP Headers containing a minimal amount of information about the specified document. The method supports the same query arguments as the GET /{db}/{docid}
method, but only the header information (including document size, and the revision as an ETag), is returned.
The ETag header shows the current revision for the requested document, and the Content-Length specifies the length of the data, if the document were requested in full.
Adding any of the query arguments (see GET /{db}/{docid}
), then the resulting HTTP Headers will correspond to what would be returned.

PUT
/{db}/{docid}
The PUT method creates a new named document, or creates a new revision of the existing document. Unlike the POST /{db}
, you must specify the document ID in the request URL.
When updating an existing document, the current document revision must be included in the document (i.e. the request body), as the rev query parameter, or in the If-Match request header.

1.4.1.1. Attachments
If the document includes attachments, then the returned structure will contain a summary of the attachments associated with the document, but not the attachment data itself.
The JSON for the returned document will include the _attachments
field, with one or more attachment definitions.
The _attachments
object keys are attachments names while values are information objects with next structure:
content_type (string): Attachment MIME type
data (string): Base64-encoded content. Available if attachment content is requested by using the following query parameters:
attachments=true
when querying a documentattachments=true&include_docs=true

.
digest (string): Content hash digest. It starts with prefix which announce hash type (
md5-
) and continues with Base64-encoded hash digestencoded_length (number): Compressed attachment size in bytes. Available if
content_type
is inlist of compressible types
when the attachment was added and the following query parameters are specified:att_encoding_info=true

1.4.1.1.2.1. Efficient Multiple Attachments Retrieving
As noted above, retrieving document with attachments=true
returns a large JSON object with all attachments included. When your document and files are smaller it’s ok, but if you have attached something bigger like media files (audio/video), parsing such response might be very expensive.
To solve this problem, CouchDB allows to get documents in multipart/related format:
Request:
GET /recipes/secret?attachments=true HTTP/1.1
Accept: multipart/related
Host: localhost:5984
Response:
HTTP/1.1 200 OK
Content-Length: 538
Content-Type: multipart/related; boundary="e89b3e29388aef23453450d10e5aaed0"
Date: Sat, 28 Sep 2013 08:08:22 GMT
ETag: "2-c1c6c44c4bc3c9344b037c8690468605"
Server: CouchDB (Erlang OTP)
--e89b3e29388aef23453450d10e5aaed0

--e89b3e29388aef23453450d10e5aaed0

1. Take R
2. Take E
3. Mix with L
4. Add some A
5. Serve with X
--e89b3e29388aef23453450d10e5aaed0--
In this response the document contains only attachments stub information and quite short while all attachments goes as separate entities which reduces memory footprint and processing overhead (you’d noticed, that attachment content goes as raw data, not in base64 encoding, right?).
1.4.1.1.3. Retrieving Attachments Encoding Info
By using att_encoding_info=true
query parameter you may retrieve information about compressed attachments size and used codec.
Request:
GET /recipes/SpaghettiWithMeatballs?att_encoding_info=true HTTP/1.1
Accept: application/json
Host: localhost:5984

"ingredients": [
"spaghetti",
"tomato sauce",
"meatballs"
],
"name": "Spaghetti with meatballs"
}
1.4.1.1.4. Creating Multiple Attachments
To create a document with multiple attachments with single request you need just inline base64 encoded attachments data into the document body:
{
"_id":"multiple_attachments",
"_attachments":
{
"foo.txt":
{
"content_type":"text\/plain",
"data": "VGhpcyBpcyBhIGJhc2U2NCBlbmNvZGVkIHRleHQ="
},
"bar.txt":
{
"content_type":"text\/plain",
"data": "VGhpcyBpcyBhIGJhc2U2NCBlbmNvZGVkIHRleHQ="
}
}
}
Alternatively, you can upload a document with attachments more efficiently in multipart/related format. This avoids having to Base64-encode the attachments, saving CPU and bandwidth. To do this, set the Content-Type header of the PUT /{db}/{docid}
request to multipart/related.
The first MIME body is the document itself, which should have its own Content-Type of application/json”. It also should include an _attachments
metadata object in which each attachment object has a key follows
with value true
.
The subsequent MIME bodies are the attachments.
Request:
PUT /temp/somedoc HTTP/1.1
Accept: application/json
Content-Length: 372
Content-Type: multipart/related;boundary="abc123"
Host: localhost:5984
User-Agent: HTTPie/0.6.0
--abc123
Content-Type: application/json
{
"body": "This is a body.",
"_attachments": {

"content_type": "text/plain",
"length": 21
},
"bar.txt": {
"follows": true,
"content_type": "text/plain",

}
}
}

1.4.1.2. Getting a List of Revisions
You can obtain a list of the revisions for a given document by adding the revs=true
parameter to the request URL:
Request:
GET /recipes/SpaghettiWithMeatballs?revs=true HTTP/1.1
Accept: application/json
Host: localhost:5984

}
The returned JSON structure includes the original document, including a _revisions
structure that includes the revision information in next form:
- ids (array): Array of valid revision IDs, in reverse order (latest first)
- start (number): Prefix number for the latest revision
1.4.1.3. Obtaining an Extended Revision History
You can get additional information about the revisions for a given document by supplying the revs_info
argument to the query:
Request:
GET /recipes/SpaghettiWithMeatballs?revs_info=true HTTP/1.1
Accept: application/json
Host: localhost:5984
Response:

],
"description": "An Italian-American dish that usually consists of spaghetti, tomato sauce and meatballs.",
"ingredients": [
"spaghetti",
"tomato sauce",
"meatballs"
],
"name": "Spaghetti with meatballs"
}
The returned document contains _revs_info
field with extended revision information, including the availability and status of each revision. This array field contains objects with following structure:
- rev (string): Full revision string
- status (string): Status of the revision. Maybe one of:
available
: Revision is available for retrieving with rev query parametermissing
: Revision is not availabledeleted
: Revision belongs to deleted document
1.4.1.4. Obtaining a Specific Revision
To get a specific revision, use the rev
argument to the request, and specify the full revision number. The specified revision of the document will be returned, including a _rev
field specifying the revision that was requested.

1.4.1.4.1. Retrieving Deleted Documents
CouchDB doesn’t actually delete documents via DELETE /{db}/{docid}
. Instead, it leaves tombstone with very basic information about the document. If you just GET /{db}/{docid}
CouchDB returns 404 Not Found response:
Request:
GET /recipes/FishStew HTTP/1.1
Accept: application/json
Host: localhost:5984
Response:
HTTP/1.1 404 Object Not Found
Cache-Control: must-revalidate
Content-Length: 41
Content-Type: application/json
Date: Wed, 14 Aug 2013 12:23:27 GMT
Server: CouchDB (Erlang/OTP)
{
"error": "not_found",
"reason": "deleted"
}
However, you may retrieve document’s tombstone by using rev
query parameter with GET /{db}/{docid}
request:
