使用generate_refresh_token.py生成Google Ads API刷新令牌遇语法错误

Hey there! I totally get how frustrating it is when you follow all the steps still hit a syntax snag—let's break down the most likely fixes for your issue.

The "invalid syntax" pointing to your Client ID/Secret usually boils down to YAML formatting mistakes or incorrect string handling in your Python script. Here's what to check:

1. Fix Your googleads.yaml File Formatting #

YAML is super picky about syntax, especially with strings that have special characters or start with numbers. Do these checks:

• Make sure there's a space after every colon. For example:

  # Correct
  client_id: "1234567890-abcdefghijklmnopqrstuvwxyz.apps.googleusercontent.com"
  client_secret: "abcdefghijklmnopqrstuvwxyz123456"
  
  # Wrong (no space after colon)
  client_id:"your-client-id"
  

• Wrap your Client ID and Secret in quotes. Since these values contain hyphens, dots, and often start with numbers, YAML might misinterpret them as non-string types (like numbers or expressions) without quotes. Single or double quotes work fine.
• Validate your YAML file to catch hidden errors. Run this quick Python snippet in the same directory as your googleads.yaml:

  import yaml
  with open("googleads.yaml", "r") as f:
      try:
          config = yaml.safe_load(f)
          print("YAML file is valid! Here's the loaded config:")
          print(config)
      except yaml.YAMLError as e:
          print(f"Found a YAML syntax error: {e}")
  

  This will tell you exactly where the problem is in your YAML file.

2. Check How You're Using Credentials in Your Script #

If you're hardcoding credentials directly in your Python script (instead of loading from YAML), make sure you're treating them as strings:

# Correct
client_id = "1234567890-abcdefghijklmnopqrstuvwxyz.apps.googleusercontent.com"
client_secret = "abcdefghijklmnopqrstuvwxyz123456"

# Wrong (no quotes—Python sees this as invalid syntax)
client_id = 1234567890-abcdefghijklmnopqrstuvwxyz.apps.googleusercontent.com

Without quotes, Python tries to parse the hyphens as subtraction, which throws a syntax error immediately.

3. Double-Check for Copy-Paste Errors #

It's easy to accidentally copy extra spaces, invisible characters, or truncated parts of your credentials. Try re-copying your Client ID and Secret directly from the Google Developer Console, then paste them into your YAML/script and verify there are no extra characters at the start or end.

If none of these fix the issue, feel free to share a redacted snippet of your googleads.yaml (hide the actual secret part!) or the line in your script where the error occurs—this will help narrow things down further.
