我正在尝试通过浏览器访问此URL
https://api.iextrading.com/1.0/stock/market/batch?symbols=fb&types=quote
它将返回这样的数据
{"FB":{"quote":{"symbol":"FB","companyName":"Facebook Inc.","primaryExchange":"Nasdaq Global Select","sector":"Technology","calculationPrice":"tops","open":146.53,"openTime":1541773800480,"close":147.87,"closeTime":1541710800308,"high":147.76,"low":145.88,"latestPrice":146.22,"latestSource":"IEX real time price","latestTime":"10:56:15 AM","latestUpdate":1541778975274,"latestVolume":4424959,"iexRealtimePrice":146.22,"iexRealtimeSize":100,"iexLastUpdated":1541778975274,"delayedPrice":146.425,"delayedPriceTime":1541778087323,"extendedPrice":146.22,"extendedChange":0,"extendedChangePercent":0,"extendedPriceTime":1541778975274,"previousClose":147.87,"change":-1.65,"changePercent":-0.01116,"iexMarketPercent":0.03662,"iexVolume":162042,"avgTotalVolume":26182829,"iexBidPrice":146,"iexBidSize":900,"iexAskPrice":146.18,"iexAskSize":100,"marketCap":420205224627,"peRatio":19.79,"week52High":218.62,"week52Low":139.03,"ytdChange":-0.19608999669275706}}}
如果我只想看到"companyName":"Facebook Inc."，什么是最好只看公司名称的URL？
