Question

我正在使用cURL请求来获取XML数据，这在浏览器中工作正常，但在PHP cURL中返回文本。我在这里看了几个类似的问题并尝试了答案，没有运气。这是代码。

$url = 'http://forecast.weather.gov/MapClick.phplat=38.4247341&lon=-86.9624086&FcstType=xml';
$agent = 'Myapp/v1.0 (http://example.org;webmaster@example.org)';

$rCURL = curl_init();

curl_setopt($rCURL, CURLOPT_URL, $url);
curl_setopt($rCURL, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($rCURL, CURLOPT_USERAGENT, $agent);
curl_setopt($rCURL, CURLOPT_HTTPHEADER, 'Content-Type: application/xml');
curl_setopt($rCURL, CURLOPT_BINARYTRANSFER, 1);

$aData = curl_exec($rCURL);
$error = curl_error($CURL);

curl_close($rCURL);

if ($error)
echo ($error);
else echo ($aData);

您的请求已包含FcstType参数，以指定应以XML格式返回响应：FcstType=xml

返回XML响应（字符串）后，可以使用SimpleXMLElement class进行解析，如下所示：

$url = 'http://forecast.weather.gov/MapClick.php?lat=38.4247341&lon=-86.9624086&FcstType=xml';
$agent = 'Myapp/v1.0 (http://example.org;webmaster@example.org)';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

$xml = new SimpleXMLElement($response);
foreach($xml->period as $period){
    echo $period->text . "\n";
}

在cURL请求上强制XML输出
