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

问题描述

我想通过此示例(天气)学习SOAP的基本用法. 如何处理这些数据?

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

响应:

<?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);

将输出

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.

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

请注意，响应的类型特定于此Web服务.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.

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.

编辑例如，更结构化"网络服务的一个示例可能是在同一站点上的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);

这给您:

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

)

现在，您只需调用即可访问值

Now you can simply access the values by invoking

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