Ruby版Evernote API求助：如何为getNoteWithResultSpec()指定全部GUID？

Hey there! Let's work through this Evernote Ruby API hiccup together—new APIs can definitely throw curveballs, so no stress 😊

First off, let's tackle the immediate issues in your code, then walk through how to properly use this method to fetch notes with the right parameters.

1. Fix the Method Name Typo! #

You've got a small but critical spelling error: getNoteWtihResultSpec should be getNoteWithResultSpec (notice the "With" instead of "Wtih"). That typo alone would cause a "method not found" error, so that's the first thing to correct.

2. Understand the Required Parameters #

The getNoteWithResultSpec method is designed to fetch a single note (not a list) with granular control over what data is returned. Here's what each parameter expects:

1. Your Evernote auth_token (you already have this right)
2. A single note GUID (this is what you were missing—you can't pass true here)
3. A ResultSpec object (defines exactly which parts of the note you want to retrieve: title, content, resources, etc.)
4. Optional boolean flags: withResourcesData, withResourcesRecognition, withResourcesAlternateData (for resource-related binary data)

3. Step 1: Get Notebook & Note GUIDs #

Before you can fetch a note, you need to get the GUID of the notebook you're targeting, then pull the GUIDs of notes inside it.

Fetch Your Notebook GUIDs #

First, list all your notebooks to grab the GUID of the one you want:

def note_store
  @note_store ||= client.note_store
end

# Get all notebooks in your account
notebooks = note_store.listNotebooks(auth_token)
notebooks.each do |notebook|
  puts "Notebook Name: #{notebook.name}, GUID: #{notebook.guid}"
end

Copy the GUID of the notebook you want to work with.

Fetch Note GUIDs from the Notebook #

Next, use that notebook GUID to get metadata (including GUIDs) for all notes in it:

# Create a filter to target your specific notebook
note_filter = Evernote::EDAM::NoteStore::NoteFilter.new(
  notebookGuid: "YOUR_NOTEBOOK_GUID" # Replace with the GUID from above
)

# Define what metadata you want to retrieve (we just need GUID and title here)
metadata_spec = Evernote::EDAM::NoteStore::NotesMetadataResultSpec.new(
  includeTitle: true
)

# Fetch up to 100 notes (adjust the 100 to your needs)
notes_metadata = note_store.findNotesMetadata(
  auth_token,
  note_filter,
  0, # Start index
  100, # Max notes to fetch
  metadata_spec
)

# Print out each note's GUID and title
notes_metadata.notes.each do |note_meta|
  puts "Note Title: #{note_meta.title}, GUID: #{note_meta.guid}"
end

Now you have all the note GUIDs you need to use with getNoteWithResultSpec.

4. Use getNoteWithResultSpec Correctly #

With a note GUID in hand, let's properly call the method. First, create a ResultSpec to specify exactly what data you want back:

# Define which parts of the note to retrieve
result_spec = Evernote::EDAM::NoteStore::ResultSpec.new(
  includeTitle: true,
  includeContent: true,
  includeResources: true # Set to false if you don't need attachments/resources
)

# Replace "YOUR_NOTE_GUID" with a GUID from the previous step
note = note_store.getNoteWithResultSpec(
  auth_token,
  "YOUR_NOTE_GUID",
  result_spec,
  false, # Set to true if you need binary data for resources (images, files)
  false, # Skip recognition data for resources
  false  # Skip alternate resource data
)

# Now you can access the note data!
puts "Title: #{note.title}"
puts "Content: #{note.content}"

5. Want All Notes in the Notebook? #

Since getNoteWithResultSpec only fetches one note at a time, you'll need to loop through all the note GUIDs you retrieved earlier to get full data for every note:

notes_metadata.notes.each do |note_meta|
  note = note_store.getNoteWithResultSpec(
    auth_token,
    note_meta.guid,
    result_spec,
    false,
    false,
    false
  )
  # Do something with each note (save to a list, print, etc.)
  puts "---"
  puts "Title: #{note.title}"
end

Quick Recap of Common Pitfalls #

• Typo alert: Always double-check the method name is getNoteWithResultSpec
• GUID requirement: The second parameter must be a single note GUID—no booleans here
• ResultSpec is mandatory: You can't skip this; it tells Evernote exactly what data to send back
• Start with metadata: Fetching notebook and note GUIDs first is the foundation of working with individual notes
