如何從谷歌財經API後2017年9月6日獲取數據的多支股票

Question

帖子9月6日

我工作的一個項目，我想從谷歌財經API顯示實時價格多股票有類似的信息changechange in %volumeTimestamp of data

和

像ROI/E，ROA，Net-profit-margin幾比率 - 這是完全可選的。 （如果可用，那麼如果不是那麼驚人，那麼問題依然不大。）

當談到效率時，發送每個股票的請求是荒謬的。

我試過許多東西一樣

https://finance.google.com/finance?q=NSE:ABAN,NSE:ABB&output=json 

這給我的股票的基本信息，但不是實時價格。

https://finance.google.com/finance?q=NSE:ABAN,ABB&output=json 

此查詢只是承認存在名稱爲ABAN的股票存在。

我對NSE（國家證券交易所 - 印度）的數據感興趣。 我已經通過2-3線程爲這件事情，但無法獲得太多的信息， 也雅虎停止支持印度市場，所以這個選項也被列入名單。

該項目是學術性的，所以我想要一個免費的數據源，如果可能的話。

任何有關這方面的幫助將非常感激。

你可以做以下伎倆：

1. 查詢標識您需要的股票（你可以做到這一次，標識似乎是永久的）：

https://finance.google.com/finance?output=json&q= ,, .. 。（最多14個股票每個查詢）

輸出將有'id'字段，你應該收集。 實施例：

{... 
"searchresults" : [ 
{ 
"title" : "Aban Offshore Ltd", 
"id" : "3302534", 
"ticker" : "ABAN", 
"exchange" : "NSE", 
... 
} , { 
"title" : "ABB India Ltd", 
"id" : "5296497", 
"ticker" : "ABB", 
"exchange" : "NSE", 
... 
}] 
... 

使用的ID

查詢信息：

https://finance.google.com/finance/data?dp=mra&output=json&catid=all&cid=3302534,5296497，...（不知道的限制，但它的方式超過14的ID）

輸出將有大約每ID信息

{...,company:{related:{cols:[...], 
rows:[ 
{id:"3302534", 
values:["3302534","ABAN","Aban Offshore Ltd","ABAN","NSE","INR","178.35","+0.40","chg","0.22","","-184.19","","0.39","0.59","10.41B","","0.00","","0.63","63.15","74.78","448.77","531.41","-5.34","-32.89","-6.46","1.40","-59.21","93.14","52.77","12.88","1,275","17,579.20","-10,408.33","9,275.71"]},

不幸的是，沒有延長會議價格e或任何最後的交易時間。 如果你知道如何獲得股票的最後交易時間，請讓我知道。
