10DMaaP Message Router utilizes an HTTP REST API to service all Publish
11and Consume transactions. HTTP and REST standards are followed so
Lasse Kaihlavirtabb7fe8c2021-02-05 17:27:03 +0200[diff] [blame^]12clients as varied as cURL, Java applications and even Web Browsers will
13work to interact with Message Router. Message Router uses AAF for user's
sunil.unnava23f58b62019-04-25 17:41:10 -0400[diff] [blame]14authentication and authorization.
15
16General HTTP Requirements
17-------------------------
18
Lasse Kaihlavirtabb7fe8c2021-02-05 17:27:03 +0200[diff] [blame^]19A DMaaP Message Router transaction consists of 4 distinct segments:
sunil.unnava23f58b62019-04-25 17:41:10 -0400[diff] [blame]20HTTP URL, HTTP Header, HTTP Body (POST) and HTTP Response. The general
21considerations for each segment are as follows and are required for each
22of the specific transactions described in this section.
23
24HTTP URL
25-------
26
27http[s]://serverBaseURL{/routing}{resourcePath}
28
29- The serverBaseURL points to DMaaP Message Router host/port that will service the request.
30
31- The resourcePath specifies the specific service, or Topic, that the client is attempting to reach
32
33HTTP Header
34-----------
35
36Specifies HTTP Headers, such as Content-Type, that define the parameters
37of the HTTP Transaction
38
39HTTP Body
40---------
41
42The HTTP Body contains the topic content when Publishing or Consuming.
43The Body may contain topic messages in several formats (like below) but
44it must be noted, that, except in very specific circumstances, messages
45are not inspected for content.
46
47
48+-------------------------+-----------------------------------------------------------------------------------------------------------------+
49| Content-Type | Description |
50+=========================+=================================================================================================================+
51| text/plain | Each line in the POST body is treated as a separate message. No partition key is specified, and therefore no |
52| | order is guaranteed. This format is mainly for test, as messages are highly likely to be re-ordered when |
53| | delivered through the Kafka cluster. |
54+-------------------------+-----------------------------------------------------------------------------------------------------------------+
55| application/json | The payload maybe a single JSON object or a JSON array of JSON objects. Each object is handled as an individual |
Lasse Kaihlavirtabb7fe8c2021-02-05 17:27:03 +0200[diff] [blame^]56| | message. Note that use of this format may result in equivalent but altered JSON objects sent to consumers. |
sunil.unnava23f58b62019-04-25 17:41:10 -0400[diff] [blame]57| | That's because MR uses a standard JSON parser to read each object into memory before pushing the object to the |
58| | Kafka system. At that point, the JSON object is re-written from the in-memory object. This can result in |
59| | re-ordered fields or changes in whitespace. If you want to preserve JSON objects exactly, |
Lasse Kaihlavirtabb7fe8c2021-02-05 17:27:03 +0200[diff] [blame^]60| | use application/cambria. Following the JSON format is recommended. |

63Publishers
64-----------
65
Lasse Kaihlavirtabb7fe8c2021-02-05 17:27:03 +0200[diff] [blame^]66**Description**: Publishes data to Kafka server on the topic mentioned in the URL.
sunil.unnava23f58b62019-04-25 17:41:10 -0400[diff] [blame]67Messages will be in the request body
68
69The MessageRouter service has no requirements on what publishers can put
70onto a topic. The messages are opaque to the service and are treated as
71raw bytes. In general, passing JSON messages is preferred, but this is
72due to higher-level features and related systems, not the MessageRouter
73broker itself.
