file_get_contents无法打开流：没有错误

Question

我试图从PHP中的URL获取JSON响应，以便回显它。 但它没有工作，并给我错误代码：

  

... [function.file-get-contents]：无法打开流：...中没有错误

所以我google了一下，发现php.ini中的allow_url_fopen可能已关闭，但在我的情况下，它已打开（我用phpinfo（）检查了它。）

我的代码如下：

<?php
   $data = file_get_contents('https://newsapi.org/v1/articles?source=bbc-news&sortBy=top&apiKey=myapikey');

   echo $data;
 ?>

此网站的正常回复如下：

  "source": "bbc-news",
  "sortBy": "top",
  "articles": [

我做错了什么？

Answer 1

你需要CURL。试试这个。不要忘记包含你的api密钥！您只需修改$url。

即可

$url = 'https://newsapi.org/v1/articles?source=bbc-news&sortBy=top';    
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$json_response = curl_exec($ch);

echo($json_response);

Answer 2

file_get_contents错误：

传递查询字符串时使用双引号

<?php

  $myapikey = "yourAPIKeyGoesHere";


   $data = file_get_contents("https://newsapi.org/v1/articles?source=bbc-news&sortBy=top&apiKey=$myapikey");

   echo $data;
 ?>
