Fake THETA

Fake THETA is a RICOH THETA Web APIs simulator. It can be used for testing applications that work with THETA Web APIs. You can switch from which model you get the responses of web APIs. Fake THETA supports the following models of THETA:

• THETA X
• THETA Z1

Features

Fake THETA provides fake responses (fixed values) for the following Web APIs. See THETA API Specifications for details of each API.

Please note that Fake THETA returns a single JPEG frame while the actual THETA device returns stream of MotionJPEG frames with Transfer-Encoding: chunked header when calling camera.getLivePreview API.

Usage

Fake THETA is implemented as vercel serverless functions deployed on "fake-theta.vercel.app". You can get the fake responses of RICOH THETA web APIs by setting https://fake-theta.vercel.app as an endpoint.

Note: "fake-theta.vercel.app" is an endpoint deployed from the master branch of this repository, so its behavior may change when the master branch is updated.

In order to specify the model, you can add a header parameter emulating-theta-model when sending a Request. If nothing is specified, Fake THETA behaves as THETA X.

Fake THETA only supports required parameters for each command execution basically. Non-required parameters, except for _detail of camera.listFiles command, are ignored in the current implementation (treated as if they were never entered). You can check if each parameter is a required parameter or not in the API Specifications.

Examples

• Get /osc/info response (THETA X)

  curl -H "emulating-theta-model:x" https://fake-theta.vercel.app/osc/info

  {
    "api": [
      "/osc/info",
      "/osc/state",
      "/osc/checkForUpdates",
      "/osc/commands/execute",
      "/osc/commands/status"
    ],
    "apiLevel": [2],
    "endpoints": { "httpPort": 80, "httpUpdatesPort": 80 },
    "firmwareVersion": "1.41.0",
    "gps": false,
    "gyro": false,
    "manufacturer": "Ricoh Company, Ltd.",
    "model": "RICOH THETA X",
    "serialNumber": "10100001",
    "supportUrl": "https://theta360.com/en/support/",
    "uptime": 67,
    "_wlanMacAddress": "00:45:78:bc:45:67"
  }

• Get camera.takePicture response (THETA X)

  curl -X POST -H "emulating-theta-model:x" \
  -H "Content-Type: application/json" \
  -d "{\"name\": \"camera.takePicture\"}" https://fake-theta.vercel.app/osc/commands/execute

  {
    "id": "10",
    "progress": { "completion": 0 },
    "name": "camera.takePicture",
    "state": "inProgress"
  }

• Get camera.getOptions response (THETA Z1)

  curl -X POST  -H "emulating-theta-model:z1" \
  -H "Content-Type: application/json" \
  -d "{\"name\": \"camera.getOptions\", \"parameters\": {\"optionNames\": [\"fileFormatSupport\"]}}" \
  https://fake-theta.vercel.app/osc/commands/execute

  {
    "name": "camera.getOptions",
    "results": {
      "options": {
        "fileFormatSupport": [
          { "height": 3360, "type": "jpeg", "width": 6720 },
          { "height": 3360, "type": "raw+", "width": 6720 }
        ]
      }
    },
    "state": "done"
  }

• Get JPG file in the camera

  curl https://fake-theta.vercel.app/files/150100525831424d42075b53ce68c300/100RICOH/R0010015.JPG \
  > ~/R0010015.JPG

TODO

• Support dynamic responses simulation according to internal states of the camera
• Support completely-reproduced error responses for each model
• Add parameter validation of APIs
• Support non-required parameters for each command
