Task Specific Operations

Last modified 22 Feb 2024 12:02 +01:00

Description

A set of operations which are specific for objects of the "Task" type residing on the "tasks" endpoint.

Request

The requests require the usage of HTTP POST. The URI of the request itself depends on the type of operation. There are THREE types of operation requests which are described on this page.

Task Suspend operation using HTTP POST
POST http://localhost:8080/midpoint/ws/rest/tasks/{oid}/suspend
Task Resume operation using HTTP POST
POST http://localhost:8080/midpoint/ws/rest/tasks/{oid}/resume
Task Run operation using HTTP POST
POST http://localhost:8080/midpoint/ws/rest/tasks/{oid}/run

Headers

Regarding authorization type, the "Basic" Authorization header should be used.

Authorization header example replace {Base64EncodedCredentials} with the encoded credentials
Authorization: Basic {Base64EncodedCredentials}

To specify the provided content type, please use the "Content-Type" header payload in the body:

Content type header example, other media types are supported as well
"Content-Type: application/json"

You might need to specify the accepted type of content in case you are interested in a format different from xml (default):

Accept type header example, other media types are supported as well
"Accept: application/json"
For supported media types please refer to the following section of the documentation

Supported Media Types

Body

The Task specific operations do not need to contain any specific payload data in the body of the request.

Options

No additional option parameters supported for these types of requests.

Response

Error code Meaning

1xx

Information. Stay tuned, operation is in progress.

2xx

Success. Operation finished successfully. There are two custom codes:

  • 250 for partial error which means that during processing some error occurred but some changes was executed.

  • 240 for handled error which means that there was originally error, but midPoint was able to fix this using its consistency mechanism.

In this two cases, midPoint returns the OperationResult where there details of executed operations can be found.

3xx

Redirection or "in progress". This is returned mostly to indicate two cases:

  • Operation has finished, but the results are not in this resource. Redirection is issues to point the client to the results. Typical example is creation of an object with POST to a collection web resource. In this case a new object is created, new URI is assigned and the client is redirected to this URI. Retrieving that URI provides created object and 200 status code, indicating that the operation is finished.

  • Operation is in progress (asynchronous operation). In this case midPoint API redirects the client to a task object that can be used to track progress of the operation.

4xx

Client errors. The client has sent request that cannot be processed. This indicates usual situation that are well handled by the midPoint code. Maybe the client request to create conflicting object, delete non-existent object, modification that violates the schema and so on. The OperationResult structure is usually provided in the response to provide more details about the situation.

5xx

Server errors. Situations that the server cannot handle and where the cause is unknown. This usually means bugs in the code, insufficient resources such as RAM or disk space, unforeseen failures in the infrastructure and so on. The OperationResult structure might or might not be provided in this case. Some errors are so severe that the structured error information might not be available.

Status codes and the indication of errors and asynchronous processing applies uniformly to all midPoint web resources (both RESTful and RPC).

Examples

Suspend a running task
# Authenticating with the credentials "administrator" and password "y0uR_P455woR*d" on a localhost instance running on port 8080
curl --user administrator:y0uR_P455woR*d -H "Accept: application/json" -H "Content-Type: application/json" -X POST http://localhost:8080/midpoint/ws/rest/tasks/6d13632c-6b75-4a33-9744-ec9523375f6b/suspend -v

The response is an HTTP 204 code in case of success with a response body.

Resume a suspended task
# Authenticating with the credentials "administrator" and password "y0uR_P455woR*d" on a localhost instance running on port 8080
curl --user administrator:y0uR_P455woR*d -H "Accept: application/json" -H "Content-Type: application/json" -X POST http://localhost:8080/midpoint/ws/rest/tasks/6d13632c-6b75-4a33-9744-ec9523375f6b/resume -v

The response is an HTTP 202 code in case of success, without a response body.

Start a Task
# Authenticating with the credentials "administrator" and password "y0uR_P455woR*d" on a localhost instance running on port 8080
curl --user administrator:y0uR_P455woR*d -H "Accept: application/json" -H "Content-Type: application/json" -X POST http://localhost:8080/midpoint/ws/rest/tasks/6d13632c-6b75-4a33-9744-ec9523375f6b/run -v

The response is an HTTP 204 code in case of success, without a response body.
