PHP在URL中使用cURL和GET请求 [英] PHP Using cURL and GET request in URL

问题描述

我使用cURL而不是file_get_contents，这在网址上正常工作，直到我使用GET请求变量代替以下网址上的城市。

I am using cURL instead of file_get_contents, which is working fine on the URL until I used a GET request variable in place of the city on the URL below.

在下面使用cURL：（Works）

Using cURL on the following: (Works)

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

这很好，但是用$ code>：

This works fine, however when substituting 'London' with a variable $city:

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';

我收到一个错误：您正在寻找的页面不存在（404）

我在cURL函数中做错了什么？这似乎与 file_get_contents 完美契合，是否有我遗漏的东西？

What am I doing wrong in my cURL function? This seems to work perfectly with file_get_contents, is there something I am missing?

cURL函数

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;

推荐答案

请用双引号替换url， / p>

Please replace double quotes with single quotes in url,

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