nGrinder에서 json 다루기

nGrinder에서 json을 다룰때는 JSONObject을 사용합니다. Python의 기본 json 을 다루는 것과는 조금 다릅니다.

만약 nGrinder안에서 Python의 samplejson을 사용하고 싶다면 samplejson 모듈을 nGrinder에 추가하고 아래와 같이 사용하면 됩니다.

simplejson 모듈을 다운로드 하고 폴더와 파일들을 nGrinder의 lib 폴더로 복사하면 됩니다.

대량의 파일을 nGrinder에 올릴때는 nGrinder에서 제공하는 svn을 사용하면 편합니다.

하지만 simplejson 모듈을 nGrinder에 업로드 하는것 보다 JSONObject를 익히는 게 더 편할 것 같습니다.
