Go：深入理解context.Background()与context.TODO()的使用及其区别

In Go language, when using the context package, the context.Background() and context.TODO() are two fundamental functions, both of which return a Context type object. Although these functions return objects that appear similar in terms of functionality, they are used for different purposes such as inter-process communication, signaling, request deadlines, etc. Consequently, their roles and meanings differ from each other.

context.Background()

该函数用于创建一个名为'Context'的对象实例，默认情况下返回一个空对象实例，默认情况下返回一个无值、无截止时间、无取消事件的'Context'对象实例，默认情况下返回一个无附加信息记录的基础对象实例，默认情况下返回一个仅作为整个程序或顶级任务处理的主要背景对象实例，
