谷歌財經API響應我有這樣的代碼:如何訪問JSON格式陣列
uri =URI.parse('http://finance.google.com/finance/info?client=i&q=NSE:ANDHRABANK')
rs = Net::HTTP.get(uri)
rs.delete! '//'
a = JSON.parse(rs)
p a
它的輸出是:
[{"id"=>"15355585", "t"=>"ANDHRABANK", "e"=>"NSE", "l"=>"49.30", "l_fix"=>"49.30", "l_cur"=>"₹49.30", "s"=>"0", "ltt"=>"3:30PM GMT+5:30", "lt"=>"Jan 13, 3:30PM GMT+5:30", "lt_dts"=>"2017-01-13T15:30:00Z", "c"=>"-0.15", "c_fix"=>"-0.15", "cp"=>"-0.30", "cp_fix"=>"-0.30", "ccol"=>"chr", "pcls_fix"=>"49.45"}]
我無法從這個JSON數組訪問數據。我想訪問像a['t']
這樣的數據。
