Golang Web Crawler

Getting Help Code Review

I am a Golang beginner. How can I solve this problem, thank you

Your job is to design and create a CLI application that will parser www.alexa.com data. The application signature should look like the following:

$ ./clawer <action> <arg1> [<arg2>...]

The application must be able to accept these actions as param and perform the corresponding tasks:

  1. top : show top sites URL on www.alexa.com
  2. country : show top 20 sites URL on www.alexa.comby country
    e.g.

$ ./clawer top
$ ./clawer country

The application needs to have an extensible interface where adding a new action is just a matter of adding more files and should
not require any modifications to the existing code base.
ps. If anything is unclear, you may set a reasonable assumption and state it at the beginning of the situation.

I’m pretty sure there are a lot on this forum that could solve the problem, though the way you asked it, it seems a lot more appropriate for the #jobs section, rather than #getting-help:code-review…

If you just want some help with implementation details, then break down the problem to the sub problem and ask more specific questions, showing parts of code you already have.
