exchange.IO("base", "https://www.alphavantage.co/")
var data = exchange.IO("api", "GET", "query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=IBM&apikey=demo");
var records = data["Time Series (Daily)"];
इस एपीआई पर जाने पर एक json,records डेटा संरचना मिलती है, और आप देख सकते हैं कि कुंजी दिनांकित है, लेकिन क्रमबद्ध नहीं हैः
{
"2020-09-09": {
"7. dividend amount": "0.0000",
"8. split coefficient": "1.0",
"1. open": "122.1300",
"2. high": "123.7000",
"3. low": "121.2900",
"4. close": "122.2600",
"5. adjusted close": "120.5590",
"6. volume": "3770678"
},
"2020-08-11": {
"6. volume": "5001176",
"7. dividend amount": "0.0000",
"8. split coefficient": "1.0",
"1. open": "128.7600",
"2. high": "130.4700",
"3. low": "126.6100",
"4. close": "126.7500",
"5. adjusted close": "124.9866"
},
……
लेकिन यदि आप सीधे ब्राउज़र में जाते हैं:https://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=IBM&apikey=demo
key की सूची क्रमबद्ध है, दिनांक के अनुसारः
"Time Series (Daily)": {
"2020-11-12": {
"1. open": "115.6300",
"2. high": "116.3700",
"3. low": "113.4800",
"4. close": "114.5000",
"5. adjusted close": "114.5000",
"6. volume": "6427016",
"7. dividend amount": "0.0000",
"8. split coefficient": "1.0"
},
"2020-11-11": {
"1. open": "118.1200",
"2. high": "118.3500",
"3. low": "116.2200",
"4. close": "117.2000",
"5. adjusted close": "117.2000",
"6. volume": "4289601",
"7. dividend amount": "0.0000",
"8. split coefficient": "1.0"
},
...
यह क्यों होता है? यदि आप एपीआई के json को एक आदेशित सरणी में बदलना चाहते हैं, जैसे कि fmz का exchange.GetRecords डेटा संरचना, तो क्या करना है?
