Ruby 在RFC3999中编码日期/时间

在RFC3999中编码日期/时间的正确方法是什么？我是不是应该把冒号给我

我的代码：

base="https://api-fxtrade.oanda.com/v1/candles?instrument="
curr="EUR_USD"
granularity="H1"
#example time: 2014-06-19T15%3A47%3A40Z
startTime=(DateTime.now-5000).to_s #current time -5000 seconds
endTime=DateTime.now.to_s
myurl=base+curr+"&candleFormat=bidask&granularity="+granularity+"&dailyAlignment=0&alignmentTimezone=America%2FNew_York&start="+startTime+"&end="+endTime
puts "---string:"
puts myurl
puts "---encoded:"
puts URI::encode(myurl)
puts "---correct example:"
puts "https://api-fxtrade.oanda.com/v1/candles?instrument=EUR_USD&start=2014-06-19T15%3A47%3A40Z&end=2014-06-19T15%3A47%3A50Z"

输出（我的目标是让时间如下面最后一行所示）：

下面是答案中的代码：

base="https://api-fxtrade.oanda.com/v1/candles?instrument="
curr="EUR_USD"
granularity="H1"
#DID NOT WORK
startTime="2014-06-19T15%3A47%3A40Z" #2014-06-19T15%3A47%3A40Z
endTime=CGI.escape(DateTime.now.to_s) #2016-06-05T04%3A26%3A30-04%3A00
#WORKS
#startTime="2014-06-19T15%3A47%3A40Z"
#endTime="2014-06-19T15%3A47%3A50Z"
puts startTime
puts endTime
myurl = "#{ base }#{ curr }&candleFormat=bidask&granularity=#{ granularity }&dailyAlignment=0&alignmentTimezone=America%2FNew_York&start=#{ startTime }&end=#{ endTime }"
puts myurl
response =HTTParty.get(myurl)

你可以试着这样做，这样可以安全地避开每次约会

require 'cgi'
require 'date'
require 'uri'

base="https://api-fxtrade.oanda.com/v1/candles?instrument="
curr="EUR_USD"
granularity="H1"

startTime=CGI.escape((DateTime.now-5000).to_s)
endTime=CGI.escape(DateTime.now.to_s)
myurl = "#{ base }#{ curr }&candleFormat=bidask&granularity=#{ granularity }&dailyAlignment=0&alignmentTimezone=America%2FNew_York&start=#{ startTime }&end=#{ endTime }"
puts "---encoded:"
puts myurl

这就产生了

https://api-fxtrade.oanda.com/v1/candles?instrument=EUR_USD&candleFormat=bidask&granularity=H1&dailyAlignment=0&alignmentTimezone=America%2FNew_York&start=2002-09-26T23%3A55%3A31-04%3A00&end=2016-06-04T23%3A55%3A31-04%3A00

当url解码器在其中一个日期上运行时，它将解码回

2016-06-04T23:55:31-04:00

我尝试了你的代码并更新了我的帖子。你知道为什么没用吗？API请求失败了，但是当我使用字符串日期（上面注释掉）时，它工作得很好。我的代码由于API错误而失败，你的代码工作得很好。我尝试了你的代码并更新了我的帖子。你知道为什么没用吗？API请求失败了，但是当我使用字符串日期（上面注释掉）时，它工作得很好。我的代码由于API错误而失败，您的代码工作得很好
