如何正确使用try.pm提供的perl中的try catch？ [英] How to properly use the try catch in perl that error.pm provides?

问题描述

我发现有一个模块错误提供try和catch功能，如java 。但是我感到困惑的是如何打印返回的异常。

I have found that there is the module Error that provides try and catch functionality like in java. But I am confused at how you can print the exception that returns.

我想了解如何执行以下

try {
    // do something that will fail!

} catch (Error e) {
    // Print out the exception that occurred
    System.out.println(e.getMessage());
}

如何使用堆栈跟踪获取错误的打印？ p>

How do I get the print of the error with the stack trace?

推荐答案

你最好使用 Try :: Tiny ，这将帮助您避免一些较旧的 perl s 。

You're probably better off using Try::Tiny which will help you avoid a number of pitfalls with older perls.

use Try::Tiny;

try {
        die "foo";
} catch {
        warn "caught error: $_";
};
