问题描述
I have tried with the following code... Without any luck...
private void updateFile(Drive service, String fileId) {
try {
File file = new File(); /********/
final java.io.File fileToUpdate = new java.io.File("D:/Work Data/Files/pdf.pdf");
FileContent mediaContent = new FileContent("image/pdf", fileToUpdate);
file = service.files().update(fileId, file, mediaContent).execute();
System.out.println(fileId);
} catch (Exception e) {
if (isDebug) {
e.printStackTrace();
}
}
}
private void updateFile(Drive service, String fileId) {
try {
File file = service.files().get(fileId).execute(); /********/
final java.io.File fileToUpdate = new java.io.File("D:/Work Data/Files/pdf.pdf");
FileContent mediaContent = new FileContent("image/pdf", fileToUpdate);
file = service.files().update(fileId, file, mediaContent).execute();
System.out.println(fileId);
} catch (Exception e) {
if (isDebug) {
e.printStackTrace();
}
}
}
每次我执行代码我得到了以下堆栈跟踪:
With every time i execute the code i get the following stacktrace:
java.lang.IllegalArgumentException
at com.google.api.client.repackaged.com.google.common.base.Preconditions.checkArgument(Preconditions.java:111)
at com.google.api.client.util.Preconditions.checkArgument(Preconditions.java:37)

at com.test.DriveTester.main(DriveTester.java:64)
任何人都可以告诉我做错了什么吗?任何示例代码,即即时更新已经存在的文件在谷歌驱动器的内容将有所帮助...
Can anyone tell what i am doing wrong ? Any sample code for this i.e. updating the content of an already existing file on google drive will be helpful...
推荐答案
我可以使用v3共享上传到已有文件的JavaScript代码
I can share javascript code for uploading to an already existing file using v3
const url = 'https://www.googleapis.com/upload/drive/v3/files/' + fileId + '?uploadType=media';
if(self.fetch){
var setHeaders = new Headers();
setHeaders.append('Authorization', 'Bearer ' + authToken.access_token);
setHeaders.append('Content-Type', mime);
var setOptions = {
method: 'PATCH',
headers: setHeaders,
body: data
};
fetch(url,setOptions)
.then(response => { if(response.ok){
console.log("save to drive");
}
else{
console.log("Response wast not ok");
}
})
.catch(error => {
console.log("There is an error " + error.message);
});
