如何在php中使用soap类(举例)? [英] How to use soap class in php (with example)?

问题描述

我想通过这个(weather)示例了解 SOAP 的基本用法.处理这些数据的价值如何?

I would like to learn the basic usage of SOAP through this (weather) example. How is it worthy to process this data?

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>

推荐答案

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>
)

其余的可以用 SimpleXML 或类似的东西解析.

The rest can then be parsed with SimpleXML or something similar.

请注意，响应类型特定于此 Web 服务.有更好的 Web 服务，它们不只是返回一个 xml 字符串，而是在 WSDL 中提供响应结构.

Note, that the kind of response is specific to this web service. There are better web services out there, which do not simply return an xml string, but rather provide the response structure within the WSDL.

编辑更结构化"网络服务的一个例子可能是同一站点上的 GeoIP 查找:

EDIT An example for a "more structured" webservice could be the GeoIP lookup on the same site:

$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
        )

)

现在您可以简单地通过调用来访问这些值

Now you can simply access the values by invoking

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