Question

当我运行下面的代码时，我收到错误：

file_get_contents（http://roblox.plus:2052/limiteds）：无法打开 stream：拒绝连接

$file = file_get_contents('http://roblox.plus:2052/limiteds');
$decode = json_decode($file, false);

foreach($decode AS $person) {
    echo $person->name . ": " . $person->lowestPrice . "<br><br>";
}

这是为什么？我可以通过浏览器访问网站。我还尝试了PHP Fiddle上的代码。

在评论之后，我尝试使用cURL - 但是没有显示结果。

$url = 'http://roblox.plus:2052/limiteds';

//  Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);

// Decode
$decode = json_decode($result, false);


foreach($decode AS $person) {
    echo $person->name . ": " . $person->lowestPrice . "<br><br>";
}

出于安全原因，许多主机会阻止您从远程URL加载文件。最好使用CURL下载文件的内容。

我尝试如下，它工作正常。

此file_get_contents方法：

<?PHP
    $file = file_get_contents('http://roblox.plus:2052/limiteds');
    $jsond = json_decode($file, true);

    foreach ($jsond['data'] as $vals) {
        echo $name = $vals["name"].' ';
        echo $lowp = $vals["lowestPrice"].'<br>';    
    }
?>

这在CURL方法中：

<?PHP
    $url = 'http://roblox.plus:2052/limiteds';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL,$url);
    $result=curl_exec($ch);
    curl_close($ch);

    $decode = json_decode($result, true);

    foreach ($decode['data'] as $vals) {
        echo $name = $vals["name"].' ';
        echo $lowp = $vals["lowestPrice"].'<br>';
    }
?>

或者你可以打开流

<?php
    // Create a stream
    $opts = array(
            'http'=>array(
                    'method'=>"GET",
                    'header'=>"Accept-language: en\r\n" .
                            "Cookie: foo=bar\r\n"
            )
    );

    $context = stream_context_create($opts);

    // Open the file using the HTTP headers set above
    $file = file_get_contents('http://roblox.plus:2052/limiteds', false, $context);
    $jsond = json_decode($file, true);

    foreach ($jsond['data'] as $vals) {
       echo $name = $vals["name"].' ';
       echo $lowp = $vals["lowestPrice"].'<br>';    
    }
?>

所有这3种方法都运行良好
