从 JSON object 中提取特定数据

Question

Currently, I am using substring() and lastIndexOf() to extract the data I need from a given JSON object. However, sometimes the JSON object's order of the data changes and as such messes up the data I retrieve.

I am looking for a more exact and precise solution of pulling example@live.com and ExampleName both without quotes from a given jwt token as seen below through the use of whatever it may be to accomplish it. Thank you.

Answer 1

why do you use substring? Your token is string? Then just convert it to object and read its properties

const obj = JSON.parse(yourToken)
const { name, email } = obj
