咨询：苹果In-App Purchase API返回的类JSON格式名称是什么？

Hey there! That special JSON-like format you're seeing after decoding an Apple IAP receipt is Apple's ASCII Property List (plist) format—sometimes called the OpenStep plist syntax.

A quick breakdown of how it differs from standard JSON: #

• Uses = instead of : to separate keys and values
• Ends each key-value pair with a ;
• Maintains curly braces for dictionaries, just like JSON, but the syntax has its own ecosystem-specific quirks

Here's your original receipt snippet for reference:

{ "purchase_info" = "123"; "subscription_id" = "7F12371239123"; }

And if you converted it to standard JSON, it would look like this:

{
  "purchase_info": "123",
  "subscription_id": "7F12371239123"
}

If you need to work with this format programmatically or convert it to something more familiar, Apple's built-in plutil command-line tool can handle conversions to JSON or XML plist formats easily. For example:

plutil -convert json input_receipt.plist -o receipt.json

This format has been a staple in Apple's ecosystem for decades, used for everything from app configuration to storing receipt data like you encountered with IAP subscriptions.
