Question

我正在使用Google云端硬盘选择器，一旦从Google云端硬盘中选择了一个项目，就会生成一个网址。问题是该URL只能由所有者访问，因此不公开。我希望URL可以公开访问。

因此，我查看了以下指南： https://developers.google.com/picker/docs/reference#Response.Documents

并认为Document.AUDIENCE类最适用，但我不知道如何将该条件添加到下面的google驱动器选择器示例代码中。

非常感谢任何帮助。

Answer 1

向所选文件添加公共权限。您需要使用驱动器API来添加文件权限

请参阅https://developers.google.com/drive/v2/reference/permissions/insert

您需要在文件中插入权限，并将角色设置为＆＃39; reader＆＃39;和任何人的类型＃39;

您可以参考示例中的javascript实现

/**
 * Insert a new permission.
 *
 * @param {String} fileId ID of the file to insert permission for.
 * @param {String} value User or group e-mail address, domain name or
 *                       {@code null} "default" type.
 * @param {String} type The value "user", "group", "domain" or "default".
 * @param {String} role The value "owner", "writer" or "reader".
 */
function insertPermission(fileId, value, type, role) {
  var body = {
    'value': value,
    'type': type,
    'role': role
  };
  var request = gapi.client.drive.permissions.insert({
    'fileId': fileId,
    'resource': body
  });
  request.execute(function(resp) { });
}

Answer 2

详细说明@ Sam的答案，以下是不使用gapi.client.drive Javascript API的方法。

假设some_id是您的文档ID：

request = gapi.client.request({
  path: '/drive/v2/files/some_id/permissions',
  method: 'POST',
  body: {
    role: 'reader'
    type: 'anyone'
  }
});
request.execute(function (res)  {
  console.log(res);
})

通过此正文向https://content.googleapis.com/drive/v2/files/some_id/permissions?alt=json生成请求：{role: "reader", type: "anyone"}

以下是您将获得的结果：

{
 "kind": "drive#permission",
 "etag": "some etage",
 "id": "anyone",
 "selfLink": "https://www.googleapis.com/drive/v2/files/some_id/permissions/anyone",
 "role": "reader",
 "type": "anyone"
}
