谷歌云端硬盘公开答案

【问题标题】：Google drive Public谷歌云端硬盘公开

【问题描述】：

我正在使用 Google 驱动器选择器，一旦从 Google 驱动器中选择了一个项目，就会生成一个 url。问题是该网址只能由所有者访问，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

并觉得 Document.AUDIENCE 类最适用，但是我不知道如何将该标准添加到下面的谷歌驱动器选择器示例代码中。

任何帮助将不胜感激。

【解决方案1】：

为所选文件添加公共权限。您将需要使用驱动器 api 添加文件权限

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

您需要向文件插入权限，角色设置为“读者”，类型设置为“任何人”

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) { });
}

感谢您的回复。你能详细说明一下吗？我如何将它与当前代码集成？

【解决方案2】：

为了详细说明@Sam 的答案，以下是不使用gapi.client.drive Javascript API 的情况。

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);
})

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

这是您将得到的结果：

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