Meteor 서버 측 메소드 호출

Question

Meteor.methods({ 
    'parseFile'() { 
     Papa.parse('/private/file/buildingData.csv', { 
      download: true, 
      complete: function(results) { 
       console.log("hi there how are you") 
       console.log(results);  // array of rows 
       return results; 
      } 
     }); 
    } 
}) 

메소드 이름의 builidingData.js 파일에 위의 메소드를 정의했습니다. 그리고 다음 코드를 사용하여 map.onRendered()에서 클라이언트로부터이 메서드를 호출합니다.

Meteor.call('parseFile', (err, res) => { 
       if (err) { 
        alert(err); 
       } else { 
        // success! 
       } 
      }); 

나는 그래서 내가 HTML 코드에서 papaparse.js를 포함하는 스크립트 태그를 사용할 필요가 없습니다 유성 meteor add harrison:papa-parse했다. 지금은 서버 측에서 데이터를 인쇄 할 수 있어요 아래에 의견을하지만, 다음과 같은 오류와 함께 기반

첫째, 반드시 CSV 파일은 당신이에 전달하는 그 길 ('/private/file/buildingData.csv')에서 액세스 할 수 있도록 참고로

dynamicTyping: true, 
download: true, //you already have this 
delimiter: ",", //or whatever the delimiter is 
linebreak: "\n", //or whatever your linebreak is
