Question

我正在使用cURL而不是file_get_contents，这在URL上正常工作，直到我在下面的URL上使用GET请求变量代替城市。

在以下内容上使用cURL :(作品）

$url = 'http://www.weather-forecast.com/locations/London/forecasts/latest';

这种方法很好，但是用变量$city替换“伦敦”：

URL: example.com/weather.php?city=London

$city = $_GET['city'];
$city = ucwords($city); 
$city = str_replace(" ", "", $city);

$url = 'http://www.weather-forecast.com/locations/".$city."/forecasts/latest';

我收到错误：The page you are looking for doesn't exist (404)

我的cURL功能有什么问题？这似乎与file_get_contents完美配合，我有什么遗漏？

cURL功能

function curl_get_contents($url)
{
$ch = curl_init();
$timeout = 5;

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

$data = curl_exec($ch);

curl_close($ch);

return $data;
}

$contents = curl_get_contents($url);
echo $contents;

请在网址中用单引号替换双引号，

$url = 'http://www.weather-forecast.com/locations/'.$city.'/forecasts/latest';
