This article describes the stock information query class implemented by PHP based on curl. Share it for your reference, as follows:
In the stock information query function, we need to capture third-party data, and then analyze these data to form what we want. Let’s take a look at a php stock information query class.
Today, a friend of mine asked me to help write a stock query class to integrate it into WeChat, so I spent a little time writing an incomplete one. Haha, if anyone wants to play, you can continue to submit the code to make it perfect! !
GitHub address:/widuu/stock, the code is as follows:
class stock{
/**
* Stock data interface
*/
const STOCK_URL = "/apistore/stockservice/stock";
/**
* Get the stock code through pinyin or Chinese characters
*/
const SOCKET_SUGGEST = "/suggest?code5=";
/**
* Single state instance
*/
private static $instance;
/**
* API key
*/
private static $apikey;
/**
* Instantiate the class and specify the API KEY
* @param apikey string
* @return instance object
*/
public static function getInstance($apikey){
if( self::$instance == NULL ){
self::$instance = new self;
self::$apikey = $apikey;
}
return self::$instance;
}
/**
* Get the stock name
* @param stockid string
* @return stockName string
*/
public static function getName($stockid){
$result = self::getSingleStock($stockid);
return $result['name'];
}
/**
* Get the last update time
* @param stockid string
* @return time string
*/
public static function getTime($stockid){
$result = self::getSingleStock($stockid);
return $result['date'].$result['time'];
}
/**
* Get the K-line chart address
* @param stockid string
* @param date string min/day/week/mouth
* @return imageUrl string
*/
public static function getKline($stockid,$date='min'){
$result = self::getSingleStock($stockid);
return $result['klinegraph'][$date.'url'];
}
/**
* Grab the data of the whole stock
* @param stockid string
* @return stock information array
*/
public static function getSingleStock($stockid){
$type = preg_match('/(\d+){6}/is', $stockid);
if ( $type == 0 ){
$stockid = self::getStockId($stockid);
}
$stock_url = self::STOCK_URL."?stockstock name not exists", 2);
return;
}
$stockid = $result['Result'][0]['code'];
$stock = explode('.', $stockid);
return $stock[1].$stock[0];
}
/**
* GET acquisition method
* @param param string parameters
* @author widuu
*/
private static function httpGet($url,$header=false) {
$curlHandle = curl_init();
curl_setopt( $curlHandle , CURLOPT_URL, $url );
if( $header ){
curl_setopt( $curlHandle , CURLOPT_HTTPHEADER , array('apikey:'.self::$apikey));
}
curl_setopt( $curlHandle , CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $curlHandle , CURLOPT_SSL_VERIFYPEER, false);
curl_setopt( $curlHandle , CURLOPT_SSL_VERIFYHOST, false);
curl_setopt( $curlHandle , CURLOPT_TIMEOUT, 10 );
$content = curl_exec( $curlHandle );
curl_close( $curlHandle );
return $header ? json_decode($content,true) :json_decode(iconv('GBK','utf-8',trim($content)),true);
}
}
//Test codestock::getInstance("5040bcbfebb0a4cffc7be278723255aa");
print_r(stock::getSingleStock('sh601000'));
echo stock::getKline('Zijin Mining');
