如何使用驱动器api java从谷歌驱动器下载文件? [英] How to download a file from google drive using drive api java?
问题描述
我尝试了Google驱动器的某些功能,但无法从Drive下载文件。
以下是我使用的代码
private static InputStream downloadFile(Drive service,File file){
if(file.getDownloadUrl()!= null&& amp ; file.getDownloadUrl()。length()> 0){
try {
HttpResponse resp =
service.getRequestFactory()。buildGetRequest(new GenericUrl(file.getDownloadUrl()))
.execute();
return resp.getContent();
} catch(IOException e){
//发生错误。
e.printStackTrace();
返回null;
}
}其他{
//文件没有存储在驱动器上的任何内容。
返回null;
当我运行脚本时,它显示 file.getDownloadUrl()
为NULL。
我在这里错过了什么?
现在,在我调用下载函数之前添加以下行,它正在执行。
File file1 = service.files()。得到(FILEID).execute();
downloadFile(service,file1);
现在问题是如何在'response'的帮助下下载文件,脚本....

字段,您可以使用
exportLinks
集合导出它们:
private static InputStream downloadFile(Drive service, File file) {
if (file.getDownloadUrl() != null && file.getDownloadUrl().length() > 0) {
try {
HttpResponse resp =
service.getRequestFactory().buildGetRequest(new GenericUrl(file.getDownloadUrl()))
.execute();
return resp.getContent();
} catch (IOException e) {
// An error occurred.
e.printStackTrace();
return null;
}
} else {
// The file doesn't have any content stored on Drive.
return null;
}
}
file.getDownloadUrl()
is NULL.File file1 = service.files().get(fileid).execute();
downloadFile(service,file1);
downloadUrl
field, instead you can export them using the exportLinks
collection:
