Nyligen har jag arbetat med ett projekt d\u00e4r vi ville integrera gratis API-aktier. Under unders\u00f6kningen kom vi \u00f6ver Alpha Vantage-<\/a> tj\u00e4nsten som tillhandah\u00e5ller aktiedata gratis. I den kostnadsfria planen tillhandah\u00e5ller de 5 API-f\u00f6rfr\u00e5gningar per minut och 500 f\u00f6rfr\u00e5gningar per dag. Denna kvot \u00e4r tillr\u00e4cklig f\u00f6r sm\u00e5 applikationer. Men om du beh\u00f6ver fler resurser, kolla in deras premiumplaner<\/a>.<\/p>\n

Alpha Vantage ger en slutpunkt f\u00f6r att h\u00e4mta aktiedata. Med hj\u00e4lp av deras API: er kan vi h\u00e4mta aktiedata f\u00f6r Intraday, Daily, Weekly, Monthly. De tillhandah\u00e5ller ocks\u00e5 grundl\u00e4ggande uppgifter som en f\u00f6retags\u00f6versikt, resultat, resultatr\u00e4kning, balansr\u00e4kning etc. Man kan ocks\u00e5 f\u00e5 valutakurser mellan olika valutor.<\/p>\n

I den h\u00e4r artikeln studerar vi hur man f\u00e5r aktiedata med Alpha Vantage i PHP. F\u00f6r att komma ig\u00e5ng, ta din API-nyckel<\/a> fr\u00e5n Alpha Vantages webbplats.<\/p>\n

Integrera API f\u00f6r gratis lager i PHP<\/h3>\n

F\u00f6r att h\u00e4mta lagerdata m\u00e5ste vi skicka HTTP-f\u00f6rfr\u00e5gningar till den angivna slutpunkten f\u00f6r Alpha Vantage. Man kan g\u00f6ra det med hj\u00e4lp av cURL. Personligen \u00e4lskar jag Guzzle<\/a> f\u00f6r detta \u00e4ndam\u00e5l. H\u00e4r kommer jag ocks\u00e5 att skicka HTTP-f\u00f6rfr\u00e5gningar och hantera svar med Guzzle.<\/p>\n

Installera Guzzle-biblioteket med kommandot:<\/p>\n

composer require guzzlehttp\/guzzle<\/code><\/pre>\n
N\u00e4r vi interagerar med Alpha Vantage API: er m\u00e5ste vi skicka GET-f\u00f6rfr\u00e5gningar till deras API-slutpunkt. API-slutpunkten https:\/\/www.alphavantage.co\/query<\/code>\u00e4r densamma f\u00f6r alla f\u00f6rfr\u00e5gningar. Den enda \u00e4ndringen kommer att g\u00f6ras i "GET" -parametrar. L\u00e5t oss b\u00f6rja med att h\u00e4mta aktiedata praktiskt taget.<\/p>\n
F\u00e5 Intradagdata<\/h4>\n
P\u00e5 API-dokumentationen<\/a> f\u00f6r Alpha Vantage hittar du detaljerna om slutpunkten och deras parametrar i detalj.<\/p>\n
Du kan f\u00e5 intradagdata f\u00f6r valfritt lager enligt f\u00f6ljande. Som ett exempel anv\u00e4nder jag f\u00f6retaget ’IBM’.<\/p>\n

Ers\u00e4tt platsh\u00e5llaren YOUR_API_KEY med din faktiska API-nyckel. H\u00e4r anv\u00e4nder jag en funktionsparameter som TIME_SERIES_INTRADAY<\/code>och intervall som 5min<\/code>.<\/p>\n
Dagliga data<\/h4>\n
Du kan f\u00e5 de dagliga uppgifterna om lager med samma slutpunkt men med olika parametrar enligt f\u00f6ljande.<\/p>\n
$response = $client->request('GET', '\/query', [\n\u00a0\u00a0\u00a0\u00a0'query' => [\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0'function' => 'TIME_SERIES_DAILY',\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0'symbol' => 'IBM',\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0'apikey' => 'YOUR_API_KEY',\n\u00a0\u00a0\u00a0\u00a0]\n]);<\/code><\/pre>\n
