Php 文件\u获取\u内容无法打开流：中没有错误

我正试图从PHP中的URL获取JSON响应，以便将其回显出来。 但它不工作，并给我错误代码：

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

所以我在谷歌上搜索了一下，发现php.ini中的

allow\u url\u fopen

可能被关闭了，但在我的例子中它被打开了（我用phpinfo（）检查了它）

我的代码如下所示：

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

   echo $data;
 ?>

{
  "status": "ok",
  "source": "bbc-news",
  "sortBy": "top",
  "articles": [
    {
      "author": "BBC News",
      "title": "Houston reels as Storm Harvey bears down on Louisiana",
      "description": "The tropical storm makes landfall in the state after leaving large parts of Houston under water.",

我做错了什么？

文件\u获取\u内容错误： 传递查询字符串时使用双引号

查看您需要的代码的实时工作演示。试试这个。别忘了包含api密钥！您只需编辑

$url

$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);

我真的建议使用

curl

，因为它比

file\u get\u contents

更易于配置和调试，而且bug更少。我想这可能是因为它是一个HTTPS请求。你试过这个答案了吗？我得到的答案是：“openssl:no http wrapper:yes https wrapper:no wrappers:array（0=>'php'，1=>'file'，2=>'data'，3=>'http'，4=>'ftp'，5=>'compress.zlib'，6=>'zip'，”。我必须下载卷发吗？不会改变任何东西，伙计。尝试both@AhmetKazaman您的变量

$myapikey

是一个字符串

myapikey

请参见我的实时示例我刚刚将真实的apikey更改为myapikey以对公众隐藏它。这不应该是问题。你检查过我在回答中提供的代码的现场演示了吗？我编辑了我的答案，并提供了一个在线链接。非常感谢。

$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);
