JSONAPIescape
重要ポイント
- Escaping protects JSON structure when text includes quotes, newlines, or backslashes.
- Escaping is a syntax safeguard, not an authorization or validation mechanism.
When escaping is mandatory
If you concatenate JSON manually, escape every dynamic string segment first.
If text comes from users, support chats, or pasted logs, assume control characters are present.
Simple workflow
Run JSON String Escape on raw text, then place the escaped output into your payload template.
Validate the final JSON with JSON Validator before shipping to API clients or webhooks.
よくある質問
Do I need escaping if payloads are generated by code?
Usually less, but any untrusted free text should still be escaped before interpolation.
Does escaping prevent injection everywhere?
No. It only makes JSON strings syntactically safe; downstream systems still need input validation.
