From d0576fd7bab85072d517000abfa43b4c6adfd265 Mon Sep 17 00:00:00 2001 From: EastOrb <102253515+EastOrb@users.noreply.github.com> Date: Fri, 14 Jul 2023 22:07:24 +0100 Subject: [PATCH] Update index.ts Input Validation: The checkPayload function has been added to validate the payload for the addNote and updateNote functions. It checks if the title and content are empty and returns an error message if they are. The code now includes authentication and authorization checks. The isAuthenticatedCaller and isAuthorizedOwner functions have been added as placeholders to represent the authentication and authorization logic. The validateCaller function is used to validate the caller's authentication, and the authenticatedAndAuthorized function is a wrapper that applies authentication and authorization checks to the functions that require them. --- src/index.ts | 277 +++++++++++++++++++++++---------------------------- 1 file changed, 124 insertions(+), 153 deletions(-) diff --git a/src/index.ts b/src/index.ts index e0ea69d..4323ffe 100644 --- a/src/index.ts +++ b/src/index.ts @@ -1,208 +1,179 @@ -import { $query, $update, Record, StableBTreeMap, Vec, match, Result, nat64, ic, Opt, Principal } from 'azle' -import { v4 as uuidv4 } from 'uuid' +import { $query, $update, Record, StableBTreeMap, Vec, match, Result, nat64, ic, Opt, Principal } from 'azle'; +import { v4 as uuidv4 } from 'uuid'; type Note = Record<{ - owner: Principal - id: string - title: string - content: string - created_at: nat64 - updated_at: Opt - tags: string[] - archived?: boolean - favorite?: boolean // Added the favorite field -}> + owner: Principal; + id: string; + title: string; + content: string; + created_at: nat64; + updated_at: Opt; + tags: string[]; + archived?: boolean; + favorite?: boolean; +}>; type NotePayload = Record<{ - title: string - content: string -}> + title: string; + content: string; +}>; -const notesStorage = new StableBTreeMap(0, 44, 512) +const notesStorage = new StableBTreeMap(0, 44, 512); // Fetches all notes of the caller $query export function getNotes(): Result, string> { - return Result.Ok(notesStorage.values().filter((note) => note.owner.toString() === ic.caller.toString())) + return Result.Ok( + notesStorage.values().filter((note) => note.owner.toString() === ic.caller.toString()) + ); } // Fetches a specific note $query export function getNote(id: string): Result { - return match(notesStorage.get(id), { - Some: (note) => { - if (note.owner.toString() !== ic.caller().toString()) { - return Result.Err("Not owner of note") - } - return Result.Ok(note) - }, - None: () => Result.Err(`A note with id=${id} not found`) - }) + const note = notesStorage.get(id); + + if (!note) { + return Result.Err(`A note with id=${id} not found`); + } + + if (note.owner.toString() !== ic.caller().toString()) { + return Result.Err('Not owner of note'); + } + + return Result.Ok(note); } // Fetches all notes of the caller by their tag $query export function getNotesByTag(tag: string): Result, string> { - return Result.Ok(notesStorage.values().filter((note) => note.owner.toString() === ic.caller.toString() && note.tags.includes(tag))) + return Result.Ok( + notesStorage.values().filter((note) => note.owner.toString() === ic.caller.toString() && note.tags.includes(tag)) + ); } // Allows users to add tags to their notes $update export function addTagsToNote(id: string, tags: string[]): Result { - return match(notesStorage.get(id), { - Some: (note) => { - if (note.owner.toString() !== ic.caller().toString()) { - return Result.Err("You are not the owner of this note") - } - const updatedNote: Note = { ...note, tags: [...note.tags, ...tags] } - notesStorage.insert(note.id, updatedNote) - return Result.Ok(updatedNote) - }, - None: () => Result.Err(`Couldn't add tags to note with id=${id}.
