Ethereum Payment QR 코드 생성기: 흔한 실수와 해결 방법
실제로 발생하는 실패 유형과 출력에서 어떻게 보이는지, 그리고 구체적인 해결 방법.
사용 방법
- 먼저 입력 인코딩을 확인하세요 — stray BOM이나 UTF-8이 아닌 붙여넣기는 도구가 실행되기 전에 결과를 망가뜨립니다.
- 조용한 잘림을 살피세요. 출력 길이가 수상하게 딱 떨어지면 뭔가 잘린 것입니다.
- 바꾼 옵션이 작업에 필요한 것인지 확인하세요. 남아 있는 기본값이 "그럴듯하지만 잘못된 결과"의 가장 흔한 원인입니다.
- 손으로 검증할 수 있는 최소 입력으로 다시 실행한 뒤 실제 데이터를 되돌려 넣으세요.
예제
EIP-681 ethereum: URI; the address must be 0x plus exactly 40 hex characters.
