Google Drive Java API V3删除自定义属性 [英] Google Drive Java API V3 delete custom property

问题描述

我正在通过服务帐户使用Java的Google Drive API，并且想删除自己设置的服装属性.

I'm using the Google Drive API for Java with a service account and I want to delete costume properties which were set by myself.

在 https://developers.google.com/drive/v3/web/迁移我读到我需要用一个映射更新文件，在该映射中我将密钥设置为空值.

At https://developers.google.com/drive/v3/web/migration I read that I need to update the file with a map where I put the key with a null value.

(带有{'properties':{'key':null}}的files.update)

我的代码如下:

File body = new File();
Map<String, String> map = new HashMap<>();
map.put(propertyName, null);
body.setProperties(map);
service.files().update(fileId, body).execute();

JSON内容为 {properties = {test = null}}

上面的代码可以正常工作，但是仍然设置了该属性.如何删除该财产?

The above code works without any exception, but the property is still set. How can I delete the property?

推荐答案

从Fromapi V2到v3，删除，更新属性和其他一些函数调用时所做的更改很少.请验证
https://developers.google.com/drive/v3/web/migration#methods
在此页面中，您可以找到properties.delete，properties.get和properties.insert
对于v3中的deleteproperties
PRIVATE:使用{'appProperties':{'key':null}}进行files.update
PUBLIC:使用{'properties':{'key':null}}

Fromapi V2 to v3 there are few changes are done while deleting, update properties and some other function calls. Please verify
https://developers.google.com/drive/v3/web/migration#methods
In this page you can find properties.delete, properties.get and properties.insert
for deleteproperties in v3
PRIVATE: files.update with {'appProperties':{'key':null}}
PUBLIC: files.update with {'properties':{'key':null}}

谢谢
