Question

这是我的代码：

require 'net/https'

uri = URI('https://api.clever.com/v1.1/sections')

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER

request = Net::HTTP::Get.new(uri.request_uri)
request.add_field 'Authorization', 'Bearer DEMO_TOKEN'

response = http.request(request)
puts response.body

问题是我的代码输出很粗，很难在终端读取。我试图用很棒的印刷品来清理它，但它不起作用......这就是我正在尝试的：

require 'net/https'
require 'awesome_print'

uri = URI('https://api.clever.com/v1.1/sections')

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER

request = Net::HTTP::Get.new(uri.request_uri)
request.add_field 'Authorization', 'Bearer DEMO_TOKEN'

response = http.request(request)
ap response.body

但它并没有按照我需要的方式进行格式化。知道发生了什么吗？

Answer 1

问题是您需要打印Hash，而不是原始String。因此，使用JSON.parse(response.body)可以解决您的问题。

或者，使用pp和json，它们都来自stdlib。

require 'net/https'
require 'pp'
require 'json'

uri = URI('https://api.clever.com/v1.1/sections')
Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
  request = Net::HTTP::Get.new(uri)
  request["authorization"] = "Bearer DEMO_TOKEN"
  http.request(request) do |response|
    pp JSON.parse(response.body)
  end
end

但最终，我建议使用pry进行调试。它只会使生活更容易10倍于debuging。

gem install pry

然后将上面的代码更改为：

require 'net/https'
require 'pry'
require 'json'

uri = URI('https://api.clever.com/v1.1/sections')
Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
  request = Net::HTTP::Get.new(uri)
  request["authorization"] = "Bearer DEMO_TOKEN"
  http.request(request) do |response|
    res = JSON.parse(response.body)
    binding.pry
  end
end

在您的终端中运行该文件后，它会暂停您放置binding.pry的位置。然后输入res，您将看到格式良好的哈希值。

与pry玩得开心！

Answer 2

awesome print以易于阅读的格式打印您的Ruby数据结构（Hash，Array等）。不适用于HTML！

如果您想以易于阅读的方式格式化HTML，请查看Nokogiri。例如：

require 'nokogiri'

# your response html
html = response.body

doc = Nokogiri::XML(html,&:noblanks)
puts doc.to_xhtml(indent:4)

Answer 3

将您的response.body解析为JSON并使用内置于更高版本JSON中的pretty_generate()函数。

require 'net/https'
require 'json'

uri = URI('https://api.clever.com/v1.1/sections')

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER

request = Net::HTTP::Get.new(uri.request_uri)
request.add_field 'Authorization', 'Bearer DEMO_TOKEN'

response = http.request(request)
myjson = JSON.parse(response.body)
puts JSON.pretty_generate(myjson)

这将为您提供输出：
