我正在从 firebase 下载数据,并将其导出到 json 中。在此之后,我尝试将其上传到 bigquery,但我需要删除大查询的新换行符才能接受它。

{   "ConnectionTime": 730669.644775033,

这就是我需要它的方式,但除了手动操作之外无法弄清楚如何做到这一点。

我正在使用 python 加载 json,读取它然后编写一个新的但无法找出正确的代码。谢谢!

这是我的 python 代码的大纲

import json
with open('nospacetest.json', 'r') as f:
data_json=json.load(f)

#b= the file after code for no line breaks is added

with open('testnoline.json', 'w') as outfile:
json.dump=(b, outfile)

最佳答案

你只需要确保 indent=None 当你 dump你的数据到 json:

with open('testnoline.json', 'w') as outfile:   
json.dump(data_json, outfile, indent=None)

引用文档:

If indent is a non-negative integer, then JSON array elements and object members will be pretty-printed with that indent level. An indent level of 0, or negative, will only insert newlines. None (the default) selects the most compact representation.
