如何通过有效载荷制作json文件

Question

I am using Mobx on ReactJs.
When I get the payload by mobs state, it gives weird json or array like below code.
For example, I need 'al' like json file. But it doesnt work due to 'P' in the front of JSon type.
How can it be edit to make a normal json type?

P {G: Array(0), l: "AIzaSzyNbEXjtG475I", o: "[DEFAULT]", u: "cool-insure-bds6a.firebaseapp.com", c: bas, …}

This string representation (with the leading 'P') is only appearing when you're converting your object to a string (with, for example, console.log ).

Use JSON.stringify(a) in order to get a valid JSON string, which you can then write to a file or do something else with it.

If you want to get back to an array from that string, use JSON.parse(str) .
