英文:
Error Handling in Go
问题
我有一个像这样的Go代码，
main()
{
做一些事情
做一些事情
.
.
.
做一些事情
}
现在，我不知道哪个“做一些事情”抛出了错误。在Go中有没有办法捕捉错误并打印出来？如何做到？
英文:
I have a go code like this,
main()
{
do something
do something
.
.
.
do something
}
Now, I don't know which "do something" is throwing an error. Is it possible in Go to catch the error and print it? How?

你可能想要使用recover。或者，检查这些函数的返回值。在Go语言中，将错误值称为ok并立即检查它是惯用的做法。
meh, ok := do_something()
if !ok {
英文:
You probably want recover. Alternatively, check the return values from those functions. It's idiomatic in go to call the error value ok, and immediately check it.
meh, ok := do_something()
if !ok {

Go语言没有包含异常处理机制。然而，它有panic/recover机制，可以提供一点异常处理功能。
英文:
Go language did not include exception handling mechanism. However, it has panic/recover mechanism which gives a little bit of exception handling.
