Expected Behavior (预期行为)
The request should be correctly imported with the URL, Headers, and the Body correctly formatted as JSON in the "Body" tab.
Actual Behavior (实际行为)
Issue A: Nothing happens after clicking Import, or an "Invalid cURL" error is displayed.
Supporting Materials (补充材料)
The issue seems related to how the parser handles:

ANSI-C Quoting: The $ before the data string (--data-raw $'...').

Escaped Newlines: The presence of \n inside the JSON string within the cURL command.

Large Payloads: Significant delays or timeouts when the request body is large.

Deployment Type
