Firebase错误：请求的数据超过了可以通过单个请求访问的最大大小 [英] Firebase error: Data requested exceeds the maximum size that can be accessed with a single request
问题描述
我需要通过Firebase控制台将 Firabase 数据库导出为 JSON ，但是当我这样做时，我会收到以下消息JSON文件：
I need to export my Firabase database as JSON via the Firebase console, however when I do so I get the following message in the JSON file:
请求的数据超过了可通过
单个请求访问的最大大小
Data requested exceeds the maximum size that can be accessed with a single request
我如何解决这个问题？
How can I fix this?
其他详细信息
这是我在控制台中使用的功能：
This is the function I use in the console:
编辑：
我发现这个试图访问太大的问题Firebase客户端的数据。我认为这两个是相关的（Firebase limit）。但是，我希望Firebase控制台UI在导出时提供该错误消息，并询问用户是否将导出分割为多个文件。我相信这是Firebase控制台的JSON导出功能中的 UX错误（如果不可能导出，应该是灰色的，或者应该允许用户调整文件大小）。
I found this question that tried to access "too big" data from a Firebase client. I presume the two are related (Firebase limit). However I would have expected the Firebase console UI to provide that error message when exporting and ask the user whether or not to split the export in multiple files. I believe that this is a UX bug in the JSON Export functionality of the Firebase console (should be greyed out if not possible to export or should allow the user to tune the file size).
推荐答案
Firebase控制台对允许导出的数据大小有限制。当您显示的位置太大而无法通过控制台导出时，导出链接确实被禁用。
The Firebase Console has limits on the size of data it allows to export. The export link should indeed be disabled when you're displaying a location that is too big to export through the console.
如果您的数据库不足256MB，您可以导出使用CURL请求：
If your database is under 256MB, you can export it with a CURL request:
curl "https://yours.firebaseio.com//.json?print=pretty&auth=CREDENTIAL"
请参阅 REST API上的文档。
如果这样也不行，你我们必须以块的形式下载数据。可能有用的工具是： https://github.com/alexklibisz/firebak
If that also doesn't work, you'll have to download the data in chunks. A tool that might be helpful with that is: https://github.com/alexklibisz/firebak
