내가 스크립트의 error_log 통화를 구매 버튼을 누르면 서비스를 두 번 호출하는 것처럼 보입니다. 동일한 메소드 호출 : payments_get_items. 응답 데이터가 올바르게 형식화 된 것 같습니다. 로그 결과는 다음과 같습니다.

payments_get_items 
{"content":[{"title":"100 Gold","description":"Premium Currency.","price":5,"image_url":"1a.png"}],"method":"payments_get_items"} 
payments_get_items 
{"content":[{"title":"100 Gold","description":"Premium Currency.","price":5,"image_url":"1a.png"}],"method":"payments_get_items"} 

Answer 1

콜백 URL이 페이스 북에 반환되는 응답에는 거의 확실하게 문제가 있습니다.

두 가지 항목이 표시된 이유는 Facebook에서 실패하기 전에 페이스 북에서 (유효한) 응답을 얻고 사용자에게 '죄송합니다. 결제 처리하는 데 문제가 있습니다 ...'라는 오류 메시지가 표시된다는 것입니다.

Facebook에 제공하는 응답 코드와 HTTP 오류 코드를 확인하고 유효한 것인지 확인하십시오.
