问题描述
任何人都可以给我一个如何使用php来使用以下Web服务的示例吗?
Can anyone give me an example of how I can consume the following web service with php?
http://www.webservicex.net/uszip.asmx?op=GetInfoByZIP
推荐答案
这是一个使用curl和GET接口的简单示例.
Here's a simple example which uses curl and the GET interface.
$zip = 97219;
$url = "http://www.webservicex.net/uszip.asmx/GetInfoByZIP?USZip=$zip";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$xmlobj = simplexml_load_string($result);
$result
变量包含如下所示的XML
The $result
variable contains XML which looks like this
<?xml version="1.0" encoding="utf-8"?>
<NewDataSet>
<Table>
<CITY>Portland</CITY>
<STATE>OR</STATE>
<ZIP>97219</ZIP>
<AREA_CODE>503</AREA_CODE>
<TIME_ZONE>P</TIME_ZONE>
</Table>
</NewDataSet>
一旦将XML解析为SimpleXML对象,您就可以像这样到达各个节点:
Once the XML is parsed into a SimpleXML object, you can get at the various nodes like this:
print $xmlobj->Table->CITY;
如果想花哨的话,可以将整个内容放到一个类中:
If you want to get fancy, you could throw the whole thing into a class:
class GetInfoByZIP {
public $zip;
public $xmlobj;
public function __construct($zip='') {
if($zip) {
$this->zip = $zip;
$this->load();
}
}
public function load() {
if($this->zip) {
$url = "http://www.webservicex.net/uszip.asmx/GetInfoByZIP?USZip={$this->zip}";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$this->xmlobj = simplexml_load_string($result);
}
}
public function __get($name) {
return $this->xmlobj->Table->$name;
}
}
然后可以像这样使用:
$zipInfo = new GetInfoByZIP(97219);
print $zipInfo->CITY;
