는 드라이브의 특정 폴더에 파일을 업로드 자바

Question

에 parentId없이 Google 드라이브에서 파일을 삽입, 나는 다음과 같은 방법의 매개 변수 parentId 설정해야 이해 : 이제

File body = new File(); 
    body.setParents(Arrays.asList(new ParentReference().setId(parentId))); 

을한다 거기에 다른 매개 변수를 사용하는 방법? 내 문제는 내 Gson 파서로 드라이브의 특정 폴더에서 리소스를 검색 할 때 parentId 속성은 항상 null입니다. 왜 그런 일이 일어나는거야? 업로드 할 때 ID를 설정해야합니까? drive.google.com 사이트에서 폴더를 직접 생성하면 어떻게됩니까? title이나 dateCreated 같은 다른 매개 변수도 제대로 작동합니다.

감사합니다.

편집 : 진행 상황을 보여주는 코드를 추가했습니다.

MyJson.java 

@SerializedName("parentId") 
private String parentId; 

@SerializedName("createdDate") 
private String createdDate; 

public final String getDateCreated(){ 
return this.createdDate; 
} 

public final String getParentId(){ 
return this.parentId; 
} 

Main.java 

public static String[] jsonParser(String jsonText){ 

Gson gson = new Gson(); 

    JsonParser parser = new JsonParser(); 

    JsonArray Jarray = parser.parse(jsonText).getAsJsonArray(); 

    ArrayList<MyJson> lcs = new ArrayList<MyJson>(); 

    StringBuilder sb = new StringBuilder(); 
    //Please ignore this Stringbuilder is just for testing purposes 
    for(JsonElement obj : Jarray) 
    { 
     MyJson cse = gson.fromJson(obj , MyJson.class); 
     lcs.add(cse); 
    } 

    List<String> strings = new ArrayList<String>(); 

    for(MyJson j: lcs){ 
     strings.add(j.getTitle()); 
     sb.append(j.getParentId() + " " + j.getDateCreated()); 
    } 

    System.out.println(sb.toString()); //Here it prints out null+date 


    String[] arr = strings.toArray(new String[strings.size()]); 

    //When I print this array shows the title perfectly 
    return arr; 

} 

이것은 이전 방법으로 전달한 텍스트 리소스입니다.

내가 거기 ID의 여러 유형이 있다는 것을 알고, 나는 (parentId, folderId)하지만 찾고 있어요하지 무엇을 어떻게해야합니까 어떻게 "웹 디자인"폴더에 파일을 삽입하기를 원한다면 ? 어떻게 그 ID를 설정할 수 있습니까? null 값으로 무엇을해야합니까?

Answer 1

부모 개체 목록과 마찬가지로 부모 개체를 같은 방식으로 읽어야합니다.

"parents": [ 
    parents Resource 
], 

아니 부모.
