데이터베이스에 JSON을 보내는 중 오류가 발생했습니다.

데이터베이스에 정보를 보내려고합니다. 그것은 괜찮아 보이는 오류가 아니지만 데이터가 데이터베이스에 전송되며, 서버 에서이 메시지를 받고 있어요/응답 (2026) 만들기 : { "메시지": "필수 입력란이 누락되었습니다", "성공" : 0}. 비슷한 게시물에서 해결책을 찾으려고했지만 운이 없었습니다.데이터베이스에 JSON을 보내는 중 오류가 발생했습니다.

미리 감사드립니다.

카테고리는 자바 코드에서 필요한 매개 변수

입니다 내가 볼 :,//params.add(New BasicNameValuePair ("catagory", catagory));

하지만 대신 카테고리의 catagory에 오타, 주석

'ingrediants'! = '성분'

'catagory'! = '카테고리'

당신이하고있는 항목 게시 및 스크립트가 찾고있는 항목이 일치하지 않습니다.

나는 그것을 고쳤지 만 지금은 비판적이다 : AsyncTask # 2 오류는 logcat 오류 메시지 – sasuri

에 대한 편집 된 버전을 보아라. 나는 정말로 자바를 모르지만 그것을 보면서 나는 어디서나 정의를 보지 못한다. 'getApplicationContext()'호출 (아마도 글로벌/어딘가에있을 수도 있습니다). 그러면 null 포인터를 반환하는 경우와 같은 오류가 발생할 수 있습니다. – AlpineCoder

아니요, 문제의 원인이 아닙니다. – sasuri
