App for Download Random Pic From PhotoPrism

Hello There,

I use the power of OpenAi and my little skills to create an app to use the API from photoprism Link: https://www.photoprism.app and give back a Random link of a Photo to use in frameOS.

I like to share my code but have no clue how so i opend an issue here.

the code in app.nim:

import options
import lib/httpclient
import frameos/apps
import frameos/types
import json
import strutils

type
  AppConfig* = object
    url*: string
    albumQuery*: string
    apiToken*: string  # Der API-Token für die Authentifizierung

  App* = ref object of AppRoot
    appConfig*: AppConfig
    downloadToken*: string  # Speichert den downloadToken

proc getSessionDownloadToken(self: App): string =
  let sessionUrl = self.appConfig.url & "/api/v1/session"
  let client = newHttpClient(timeout = 30000)
  client.headers.add("Authorization", "Bearer " & self.appConfig.apiToken)

  try:
    let response = client.getContent(sessionUrl)
    let jsonResponse = parseJson(response)

    if jsonResponse.hasKey("config") and jsonResponse["config"].hasKey("downloadToken"):
      self.downloadToken = jsonResponse["config"]["downloadToken"].getStr()
      return self.downloadToken
    else:
      self.logError "Kein downloadToken in der Antwort gefunden."
      return ""
  except CatchableError as e:
    self.logError "Fehler bei der Anfrage: " & e.msg
    return ""
  finally:
    client.close()

proc getRandomPhotoHash(self: App): string =
  let photosUrl = self.appConfig.url & "/api/v1/photos?count=1&offset=0&q=" & self.appConfig.albumQuery & "&order=random"
  let client = newHttpClient(timeout = 30000)
  client.headers.add("Authorization", "Bearer " & self.appConfig.apiToken)

  try:
    let response = client.getContent(photosUrl)
    let jsonResponse = parseJson(response)

    if jsonResponse.kind != JArray or jsonResponse.len == 0:
      self.logError "Kein Bild gefunden."
      return "Kein Bild gefunden."

    let photoHash = jsonResponse[0]["Hash"].getStr()
    return photoHash
  except CatchableError as e:
    self.logError e.msg
    return e.msg
  finally:
    client.close()

proc getPhotoDownloadUrl(self: App, photoHash: string): string =
  # Erstelle die Download-URL basierend auf dem Hash und dem downloadToken
  return self.appConfig.url & "/api/v1/t/" & photoHash & "/" & self.downloadToken & "/fit_1280"

proc get*(self: App, context: var ExecutionContext): string =
  if self.getSessionDownloadToken().len == 0:
    return "Fehler beim Abrufen des downloadToken."

  let photoHash = self.getRandomPhotoHash()

  if photoHash != "Kein Bild gefunden.":
    return self.getPhotoDownloadUrl(photoHash)
  else:
    return photoHash
