Turn a cURL Command into Safer Application Code

A converter must not execute the command

A cURL command may carry tokens, cookies, personal data, or internal addresses in its URL, headers, and body. Conversion needs no network access: safely tokenize text and generate an equivalent request draft.

Shell syntax varies. Quotes, line continuations, and options such as `--data-raw` need a bounded tokenizer. Unsupported options should trigger warnings rather than disappear silently.

Separate secrets from code

Authorization, Cookie, X-API-Key, and user credentials may appear during conversion. Replace values with explicit placeholders before pasting code into issues, chats, or documentation. Revoke and rotate exposed credentials rather than merely deleting them.

Read production secrets from environment variables or a secret manager. A key embedded in client JavaScript cannot be hidden; confidential credentials belong behind an authorized backend boundary.

• Redact Authorization and Cookie from logs.
• Clearly mark fake demo values.
• Prefer narrow, short-lived tokens.

Carry HTTP behavior accurately

A body may imply POST when no method is supplied, but confirm the API contract. Content-Type must match body encoding. Sending JSON as form data or encoding twice can break parsing and signatures.

Redirects, compression, TLS bypass, and proxy flags do not map equally across languages. Never carry `-k/--insecure` into production. Generated output is a starting draft, not a behavioral-equivalence proof.

Add timeouts, errors, and cancellation

Fetch rejects on network failure, not on HTTP 404 or 500; inspect response.ok/status. Treat transport and HTTP errors separately in requests and PHP cURL, and always set finite timeouts.

Retry only idempotent operations or requests with idempotency keys. Check Content-Type before assuming JSON, bound error-body reads, and avoid logging sensitive responses.
