使用PHP

Question

我想检索与天气有关的XML数据。 为此，我使用此API。

https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text=%22Kandy%22)

我尝试用PHP中的CURL来解决它

这是我的代码

$url = "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text=%22Kandy%22)";

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);    // get the url contents

$data = curl_exec($ch); // execute curl request
curl_close($ch);

$xml = simplexml_load_string($data);
print_r($xml);

但它检索没有任何文本的空白输出。请帮我解决这个问题。

您需要像这样初始化cURL请求：

   $url = "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text=%22Kandy%22)";

    $ch=curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);    // get the url contents

    $data = curl_exec($ch); // execute curl request
    curl_close($ch);

    $xml = (array)simplexml_load_string($data);
    echo "<pre>";
    print_r($xml);
    echo "<pre>";
