节点console.log默认截断输出。如何查看完整输出？ [英] Node console.log truncates output by default. How can I see the full output?

问题描述

Node的console.log似乎默认截断输出，例如，查看API的输出：

Node's console.log seems to truncate output by default, eg, looking at the output from an API:

{ '@': { xmlns: 'http://ec2.amazonaws.com/doc/2012-03-01/' },
   requestId: '123456',
   reservationSet: 
   { item: 
      { reservationId: 'r-123456',
       ownerId: '123456',
       groupSet: [Object],
       instancesSet: [Object],
       requesterId: '123456' } } }

如您所见， [object] 未展开。我想这是一个方便的措施 - 很多人不希望节点默认喷出数千行。有没有办法告诉它扩展记录项目的内容？

As you can see, [object] isn't expanded. I guess this is a convenience measure - a lot of people wouldn't want node spewing thousands of lines by default. Is there a way I can tell it to expand the logged item's contents?

推荐答案

没有选项可以更改 console.log ，但是你可以使用捆绑的util库中的函数， util.inspect ，它接受深度参数。例如：

There is no option to change console.log, however you can use a function in the bundled util library, util.inspect which does accept a depth parameter. Eg:

 console.log(require('util').inspect(obj, true, 10)); // 10 levels deep
