유형 불일치 오류가 stringbody

Question

val tName = System.getProperty("tName", "asdflkjh") 

에서 "TNAME"을 통과하면서 나는 "tName" 동적으로 만들 계획입니다 표시되어 있지만 대신 "asdflkjh"의 출력에 "$tName"을 인쇄합니다. 내가 stringBody에 'session=>s'를 사용하는 경우 .body(StringBody("""{"objectId":${assetid},"objectType":"m-asset","name1": "$tName","accountId":4,"userId":5}"""))

는 오류 아래 .body(StringBody(session=>s"""{"objectId":${assetid},"objectType":"m-asset","name1": "$tName","accountId":4,"userId":5}"""))

Answer 1

오류는 문자열 보간 (s"""...""")로 전환 할 때 그래서 오해, 당신은 이미 문자열에 $을 가지고 그냥 : 예,이 일을하려고하면. $$을 사용하여 이스케이프 처리하십시오 (s"""{"objectId":$${assetid},"objectType":"m-asset","name1": "$tName","accountId":4,"userId":5}"""). session => ... 부분은 문자열 보간법과 완전히 직교합니다.

나는 안전하지 않습니다 : tName에 따옴표가 포함 된 경우 어떻게해야합니까? 이 경우 환경 변수를 제어하는 ​​시스템에서 스크립트를 실행하려고하지만 "SQL injection"을 찾아보고 문제가 SQL에 국한되지 않음을 알고 있다고 가정하면 중요하지 않을 수 있습니다.

Answer 2

환경 변수 값을 얻으려고합니까?

val tName = sys.env("tName").getOrElse(doSomething here...)
