我正在使用基于此示例的足够简单的实现:http: //www.appelsiini.net/2010/using-bitly-with-httparty
我把这个文件放在lib文件夹(bitly.rb)
require 'rubygems'
require 'httparty'
class Bitly
include HTTParty
base_uri "api.bit.ly"
@@login = "goldhat"
@@api_key = "R_xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
def self.shorten(url)
response = get("/v3/shorten?login=#{@@login}&apiKey=#{@@api_key}&longUrl=#{url}")
response["data"]["url"]
end
end
出于某种原因,我得到了一个 nil 对象。好像 bitly 甚至没有响应任何数据。我在我的控制台和我的应用程序中对其进行了测试,并得到了同样的错误:
NoMethodError: You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
from c:/goldhat_production/lib/bitly.rb:9:in `shorten'
from (irb):1
有任何想法吗?
