php - 如何在php中使用soap类(示例)？

Question

我想通过这个 (weather) 示例了解 SOAP 的基本用法。如何处理这些数据？

请求:

POST /globalweather.asmx HTTP/1.1
Host: www.webservicex.net
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <GetWeather xmlns="http://www.webserviceX.NET">
      <CityName>string</CityName>
      <CountryName>string</CountryName>
    </GetWeather>
  </soap12:Body>
</soap12:Envelope>
HTTP/1.1 200 OK
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

回复:

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <GetWeatherResponse xmlns="http://www.webserviceX.NET">
      <GetWeatherResult>string</GetWeatherResult>
    </GetWeatherResponse>
  </soap12:Body>
</soap12:Envelope>

Answer 1

最简单的方法是:

$requestParams = array(
    'CityName' => 'Berlin',
    'CountryName' => 'Germany'
);

$client = new SoapClient('http://www.webservicex.net/globalweather.asmx?WSDL');
$response = $client->GetWeather($requestParams);

print_r($response);

会输出

stdClass Object
(
    [GetWeatherResult] => <?xml version="1.0" encoding="utf-16"?>
<CurrentWeather>
  <Location>Berlin-Tegel, Germany (EDDT) 52-34N 013-19E 37M</Location>
  <Time>Jan 26, 2012 - 07:50 AM EST / 2012.01.26 1250 UTC</Time>
  <Wind> from the SE (130 degrees) at 14 MPH (12 KT):0</Wind>
  <Visibility> greater than 7 mile(s):0</Visibility>
  <SkyConditions> mostly clear</SkyConditions>
  <Temperature> 33 F (1 C)</Temperature>
  <Wind>Windchill: 23 F (-5 C):1</Wind>
  <DewPoint> 21 F (-6 C)</DewPoint>
  <RelativeHumidity> 59%</RelativeHumidity>
  <Pressure> 30.27 in. Hg (1025 hPa)</Pressure>
  <Status>Success</Status>
</CurrentWeather>
)

然后可以使用 SimpleXML 或类似的东西解析其余部分。

请注意，响应的类型特定于此 Web 服务。那里有更好的 Web 服务，它们不只是返回 xml 字符串，而是在 WSDL 中提供响应结构。

编辑“更结构化”的网络服务的示例可以是同一站点上的 GeoIP 查找:

$client = new SoapClient('http://www.webservicex.net/geoipservice.asmx?WSDL');
$result = $client->GetGeoIP(array('IPAddress' => '8.8.8.8'));

print_r($result);

这给你:

stdClass Object
(
    [GetGeoIPResult] => stdClass Object
        (
            [ReturnCode] => 1
            [IP] => 8.8.8.8
            [ReturnCodeDetails] => Success
            [CountryName] => United States
            [CountryCode] => USA
        )

)

现在您可以通过调用简单地访问这些值

$country = $result->GetGeoIPResult->CountryName;
