File_get_contents($url): 无法打开流

我有一个脚本，我使用以下方法读取文件：

file_get_contents(urlencode($url));

我收到此错误：

failed to open stream: HTTP request failed! HTTP/1.0 400 Bad request

I tried this http://php.net/manual/fr/function.file-get-contents.php，但我仍然收到错误。 我试过这个：

ini_set('default_socket_timeout', 120);

This:

$opts = array('http'=>array('timeout' => 120));
         $context = stream_context_create($opts);
         $resul = file_get_contents($url,0,$context);

和这个：

$opts = array('http'=>array('timeout' => 120,'header'=>'Connection : close'));
         $context = stream_context_create($opts);
         $resul = file_get_contents($url,false,$context);

你能帮我找出为什么我会收到错误吗？

您只需要编码“querystring”，提取查询并对其进行编码，在附加编码后的查询“url”后。

Note: file_get_contents需要allow_url_fopen=On在“php.ini”中，尝试使用curl

示例（阅读我在代码中的注释）

注意：此示例出现连接错误和 http 错误

<?php
//Set your page example
$uri = 'http://localhost/path/webservice.php?callback=&id=153&provenance=153&ret=a:1:{s:5:"infos";a:8:{s:8:"civilite";s:3:"Mme";s:5:"lname";s:0:"";s:5:"fname";s:8:"Nathalie";s:5:"email";s:17:"[email protected] /cdn-cgi/l/email-protection";s:3:"tel";s:0:"";s:7:"adresse";s:0:"";s:6:"date_n";s:14:"10:"01/06/1969";s:2:"cp";s:0:"";}}';

//extract url
$parsed_url = parse_url($uri);

//Create fixed url
$fixed_url = $parsed_url['scheme'] . '://' . $parsed_url['host'] . $parsed_url['path'];

//If exists query
if (isset($parsed_url['query'])) {
    $output = array();
    $result = array();

    //Extract querystring
    parse_str($parsed_url['query'], $output);

    //Encode values in querystring
    forEach($output as $k => $v) {
        $result[] = $k . '=' . rawurlencode($v);
    }

    //Append encoded querystring
    $fixed_url .= '?' . implode('&', $result);
}

echo 'GET url: ', $fixed_url, '<br>';

//Get result in page
$ch = curl_init();
$timeout = 30; //set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $fixed_url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

$file_contents = curl_exec($ch);

$errornum = curl_errno($ch);

$info = curl_getinfo($ch);

$status = (int) $info['http_code'];

if ($errornum !== 0) {
    echo 'Error: ', curl_error($ch);
    $file_contents = NULL;
} else if ($status !== 200) {
    echo 'http_error: ', $status;
    $file_contents = NULL;
} else {
    echo 'Result:<hr>';
    echo $file_contents;
}

curl_close($ch);
?>
