Websocket API

ZendHQ provides a websocket API that communicates using JSON-RPC.

Basic Usage

You need a websocket client, such as uswc to connect to the websocket. A number of programming languages have either native websocket support, or can provide it via libraries, extensions, or plugins.

You connect to the websocket via the ZendHQ server's IP or DNS address (for example, 127.0.0.1, localhost) and its port. The default port is 10091, custom ports are defined in the zendhqd.daemon_uri setting.

The following example uses uswc:

$ uswc ws://127.0.0.1:10091

Once connected, initialize a session, using the configured ZendHQ token:

{"id":1","method":"session.create","params":{"token":"..."}}

When successful, you receive a response indicating a session has been initialized. At this point, you can proceed to call other request methods in the API as described in the remainder of this document.

Request

A request is a remote procedure call sent by the client to the server. The request is a single JSON object that has the following members:

Member Description
id An identifier established by the client
method A string containing the name of the method to be invoked
params A structured value that holds the parameter values for the method

id

The id member contains an identifier that contains a string or a number. The server response to the request contains the same identifier.

The clients generates an identifier value for every request and the server responds with the same identifier value.

This member is required.

Note: Set the member to any value you want. We recommend starting with 1 and incrementing from there. Use unique values during a given websocket session; the values only need be unique for a given session.

method

The method member contains the name of the method to be invoked. Method names can include an optional namespace prefix separated with the period character:

[<namespace>.]<methodname>

This member is required.

params

The params member contains a structured value holding the parameter values for the method. Represent parameter values as an array (by position) or as an object (by parameter name).

This member is optional.

Response

The server responds to client requests with a response. The response is a single JSON object that has the following members:

Member Description
id The identifier established by the client
result The result of the remote procedure call
error Error object

id

The id member is the identifier established by the client and identifies the request to which the response belongs.

This member is required.

result

The result member contains the result of the remote procedure call and is determined by the method invoked on the server. This member is required on success. This member must not exist if there was an error.

error

The error member contains an error object. This member is required if there was an error. This member must not exist on success.

The error object has the following members:

Member Description
code A number that identifies the type of the error
message A string describing the error
data Optional additional information about the error

The code member can have one of the following values:

Value Description
-32700 Failed to parse JSON
-32600

Invalid request

-32601 Requested method not found
-32602

Invalid or missing parameters

-32603 Internal server error
-32000

Invalid session

-32001 Authentication failed
-32002 Not licensed

Notification

Notifications are events sent by the server to the client. They are not related to any requests made by the client. For most of the notifications the client must first subscribe for the specific type of events.

Notifications are JSON objects with the following members:

Member Description
event A string identifying the event
params A structured value that holds the parameter values for the event

event

The event member is a string that identifies the event. Event names can include an optional namespace prefix separated with the period character:

[<namespace>.]<eventname>

This member is required.

params

The params member contains a structured value holding the parameter values for the event. Represent parameter values as an array (by position) or as an object (by parameter name).

This member is optional.

Batch

The client may send several Request objects at the same time by sending a JSON array filled with Request objects.

The server responds with an array containing the corresponding Response objects, after all the batch Request objects have been processed.

The Response objects being returned from a batch may be returned in any order within the array. The client must match contexts between the set of Request objects and the resulting set of Response objects based on the id member within each object.

If the batch rpc call itself fails to be recognized as a valid JSON or as an array with at least one value, the response from the server is a single Response object.

Examples

Namespace "jq"

The jq namespace manages Job Queue jobs and queues.

  • A Job Queue job is a task that ZendHQ executes asynchronously on the ZendHQ daemon’s node or optionally on PHP nodes. The job can, for example, perform an HTTP request to a specific server.

  • A Job Queue queue is a scheduler that executes tasks one by one. The execution order is determined by the schedule and priority of jobs. Clients can create multiple Job Queue queues to execute tasks in parallel.

The client must have a session associated with it and the ZendHQ license must be valid.

Queue identifier

Job Queue queues are identified by a name or a numeric ID value. The jq namespace handler allows entering queue identifiers in multiple ways:

  • as a JSON object with elements name or id;

  • as a JSON string value with the name of the queue;

  • as a JSON numeric value with the ID value of the queue.

Queue name must be more than zero and less 256 characters long.

Queue ID value must be a positive integer value including zero.

The special ID value 0 is used to identify the default queue even if the default queue has a different ID value.

The following are valid queue identifiers:

"queue":{"name":"feeds"}
"queue":{"id":2}
"queue":"feeds"
"queue":2

Default Queue

The Job Queue always has a default queue, which cannot be deleted. By default, the default queue is identified by the queue name "__default__". The ID value 0 always identifies the default queue even if the actual ID value is different.

jq.version method

Requests the jq namespace API version number from the server.

Request

Member Description
method Fixed string "jq.version"

Response

The result member contains the following values:

Member Description

jq.subscribe method

Subscribes the client to Job Queue notification events. Replaces any previous Job Queue subscriptions for the same client.

Request

Member Description
method

Fixed string "jq.subscribe"

params Optional JSON object with subscription filters

The params member CAN contain the following elements:

Member Description
queue

Queue identifier or JSON array with queue identifiers

job_id

Job ID value or JSON array with job ID values (see notes below)

task_id Task ID value or JSON array with task ID values (see notes below)

Without any elements in the subscription filter, the client is subscribed to all the Job Queue notifications events.

With a queue element as an empty JSON array, the client is subscribed to all the queue related events.

With a queue elements as a single queue identifier or a JSON array with queue identifiers, the client is subscribed to specific queue related events.

Elements job_id and task_id are currently trigger elements and can have any value. At least one valid queue identifier must be specified in the queue element for these elements to be accepted.

If the job_id element exists with any values, then the client is also subscribed to all the job related events within specified queues.

If the task_id element exists with any values, then the client is also subscribed to all the task related events within specified queues.

Notice that the preferred value for job_id and task_id elements is an empty JSON array, which is future proof and keeps working the same way when additional job or task filtering is added.

Response

The result member contains the fixed string "OK".

Example

Client subscribes to all the queue and job related notification events in the queue “feeds”:

Client:

{"id":2,"method":"jq.subscribe","params":{"queue":{"name":"feeds"},"job_id":[]}}

Server:

{"id": 2, "result": "OK"}

jq.unsubscribe method

Value Description
name

Name uniquely identifying the queue

The name member value is a string up to 256 characters uniquely identifying the queue. The name member value cannot be empty.

The params member can contain the following additional values:

Value Description
suspended

JSON boolean true value for creating suspended queues

priority

Priority of the queue

job_defaults

JSON object with default values for jobs added to this queue

Queue priority value also affects the accuracy of scheduling timers. Higher priority queues are more likely executing jobs at the exact time scheduled for the job.

Notice that higher priority queues are more cpu intensive and can actually cause queue starvation if abused.

The job_defaults member specifies default values for jobs added to this queue and CAN have the following values:

Job Defaults
