PHPでcurlを使用してjson結果を得ることができません

Question

ここでは、ライブ株式市場（https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/ajaxGetQuoteJSON.jsp?symbol=tcs）からJSONデータを取得しようとしています。

このURLは、WebブラウザでJSONデータを返します。しかしcurlまたはfile_get_contentsを使用してJSONの詳細を取得できません。

PHPコード：

$url='https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/ajaxGetQuoteJSON.jsp?symbol=tcs'; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_URL,$url); 
$result=curl_exec($ch); 
curl_close($ch);  
$result_array =json_decode($result, true); 

print_r($result_array);//Empty result 

Answer 1

、このいずれかを試してみてください、それが正常に動作しています。あなたはいくつかの必要なヘッダーを欠いていました。 このURLは、このヘッダーなしUser-Agent

<?php 
$url='https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/ajaxGetQuoteJSON.jsp?symbol=tcs'; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_URL,$url); 
curl_setopt($ch, CURLOPT_HTTPHEADER,array(
"Accept-Encoding:UTF-8", 
"Content-type: application/json", 
"User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36")); 
$result=curl_exec($ch); 
curl_close($ch); 

$result_array =json_decode($result, true); 

print_r($result_array); 

を任意の結果を与えるものではありません出力：
