php 谷歌天气 API 查询

我无法从 google api 检索数据。当我运行代码时，它只返回一个空白页，而不是 xml 数组的打印输出。这是代码：

$url="http://www.google.com/ig/api";

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "?weather=london,england");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

$data = curl_exec($ch); 

curl_close($ch); 


echo "<pre>";
print_r($data);

I'm having trouble retrieving data from the google api. When I run the code, it only returns a blank page and not a printout of the xml array. Here is the code:

$url="http://www.google.com/ig/api";

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "?weather=london,england");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

$data = curl_exec($ch); 

curl_close($ch); 


echo "<pre>";
print_r($data);

我认为问题在于您使用 POST 方法，而不是 GET
尝试这样

$url="http://www.google.com/ig/api?weather=london,england";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

$data = curl_exec($ch); 

curl_close($ch);

希望它有帮助:)

编辑：是的，你必须做一些额外的解析才能从 XML 字符串中获取数据

I think that the problem is that you use POST method, and not the GET
Try like this

$url="http://www.google.com/ig/api?weather=london,england";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

$data = curl_exec($ch); 

curl_close($ch);

Hope it helps :)

EDIT: And yes, you have to do some extra parsing to get the data from the XML string
