Detailed Description

Function Documentation

◆ OrthancPluginCallRestApi()

OrthancPluginErrorCode OrthancPluginCallRestApi ( OrthancPluginContext context,
OrthancPluginMemoryBuffer answerBody,
OrthancPluginMemoryBuffer answerHeaders,
uint16_t *  httpStatus,
OrthancPluginHttpMethod  method,
const char *  uri,
uint32_t  headersCount,
const char *const *  headersKeys,
const char *const *  headersValues,
const void *  body,
uint32_t  bodySize,
uint8_t  afterPlugins 
)

Make a call to the given URI in the REST API of Orthanc. The result to the query is stored into a newly allocated memory buffer. This function is always granted full access to the REST API (no credentials, nor security token is needed).

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
answerBodyThe target memory buffer (out argument). It must be freed with OrthancPluginFreeMemoryBuffer(). The value of this argument is ignored if the HTTP method is DELETE.
answerHeadersThe target memory buffer for the HTTP headers in the answer (out argument). The answer headers are formatted as a JSON object (associative array). The buffer must be freed with OrthancPluginFreeMemoryBuffer(). This argument can be set to NULL if the plugin has no interest in the answer HTTP headers.
httpStatusThe HTTP status after the execution of the request (out argument).
methodHTTP method to be used.
uriThe URI of interest.
headersCountThe number of HTTP headers.
headersKeysArray containing the keys of the HTTP headers (can be NULL if no header).
headersValuesArray containing the values of the HTTP headers (can be NULL if no header).
bodyThe HTTP body for a POST or PUT request.
bodySizeThe size of the body.
afterPluginsIf 0, the built-in API of Orthanc is used. If 1, the API is tainted by the plugins.
Returns
0 if success, or the error code if failure.

◆ OrthancPluginGenerateRestApiAuthorizationToken()

char* OrthancPluginGenerateRestApiAuthorizationToken ( OrthancPluginContext context)

This function generates a token that can be set in the HTTP header "Authorization" so as to grant full access to the REST API of Orthanc using an external HTTP client. Using this function avoids the need of adding a separate user in the "RegisteredUsers" configuration of Orthanc, which eases deployments.

This feature is notably useful in multiprocess scenarios, where a subprocess created by a plugin has no access to the "OrthancPluginContext", and thus cannot call "OrthancPluginRestApi[Get|Post|Put|Delete]()".

This situation is frequently encountered in Python plugins, where the "multiprocessing" package can be used to bypass the Global Interpreter Lock (GIL) and thus to improve performance and concurrency.

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
Returns
The authorization token, or NULL value in the case of an error. This string must be freed by OrthancPluginFreeString().

◆ OrthancPluginGetDicomForInstance()

OrthancPluginErrorCode OrthancPluginGetDicomForInstance ( OrthancPluginContext context,
OrthancPluginMemoryBuffer target,
const char *  instanceId 
)

Retrieve a DICOM instance using its Orthanc identifier. The DICOM file is stored into a newly allocated memory buffer.

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
targetThe target memory buffer. It must be freed with OrthancPluginFreeMemoryBuffer().
instanceIdThe Orthanc identifier of the DICOM instance of interest.
Returns
0 if success, or the error code if failure.

◆ OrthancPluginGetGlobalProperty()

char* OrthancPluginGetGlobalProperty ( OrthancPluginContext context,
int32_t  property,
const char *  defaultValue 
)

Get the value of a global property that is stored in the Orthanc database. Global properties whose index is below 1024 are reserved by Orthanc.

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
propertyThe global property of interest.
defaultValueThe value to return, if the global property is unset.
Returns
The value of the global property, or NULL in the case of an error. This string must be freed by OrthancPluginFreeString().

◆ OrthancPluginLookupInstance()

char* OrthancPluginLookupInstance ( OrthancPluginContext context,
const char *  sopInstanceUID 
)

Look for an instance stored in Orthanc, using its SOP Instance UID tag (0x0008, 0x0018). This function uses the database index to run as fast as possible (it does not loop over all the stored instances).

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
sopInstanceUIDThe SOP Instance UID of interest.
Returns
The NULL value if the instance is non-existent, or a string containing the Orthanc ID of the instance. This string must be freed by OrthancPluginFreeString().

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
patientIDThe Patient ID of interest.
Returns
The NULL value if the patient is non-existent, or a string containing the Orthanc ID of the patient. This string must be freed by OrthancPluginFreeString().

◆ OrthancPluginLookupSeries()

char* OrthancPluginLookupSeries ( OrthancPluginContext context,
const char *  seriesUID 
)

Look for a series stored in Orthanc, using its Series Instance UID tag (0x0020, 0x000e). This function uses the database index to run as fast as possible (it does not loop over all the stored series).

Parameters
contextThe Orthanc plugin context, as received by OrthancPluginInitialize().
seriesUIDThe Series Instance UID of interest.
Returns
The NULL value if the series is non-existent, or a string containing the Orthanc ID of the series. This string must be freed by OrthancPluginFreeString().
