file_get_contents with打开流失败

Question

我尝试从PHP中的file_get_contents() -函数网站获得文本。

        $myVariable = file_get_contents('myUrl/json/file.json?jsonp=loadSomething);

不幸的是，我一直收到消息

"Warning:
file_get_contents(myUrl/json/file.json?jsonp=loadSomething): 
failed to open stream: HTTP request failed! 
HTTP/1.1 404 Not Found in *path of my .php- file* on line 10"

在php.ini中，allow_url_fopen被设置为"On"。我也试过urlencode()。我能做些什么来让我的代码工作?

OK，远程文件可以访问。当file_get_contents失败时，cURL是您的朋友:

function file_get_contents_curl($url) {
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)');
    $data = curl_exec($curl);
    curl_close($curl);
    return $data;
}

现在尝试

$myVariable = file_get_contents_curl('myUrl/json/file.json?jsonp=loadSomething');
