最后讓我們看一個簡單的實際例子來理解PHP5風(fēng)格的SoapClient這個服務(wù)。假設(shè)有這樣的一個例子,我們需要查看美國伊利諾斯州的moline的天氣。這個獲得當前moline飛機場天氣狀態(tài)的代碼稱為”KMLI”,需要調(diào)用getWeatherReport()方法和傳遞’KMLI’字符串作為參數(shù)。這個調(diào)用將返回一個WeatherReport對象。

class ProxyTestCase extends UnitTestCase {
function TestGetWeatherReport() {
$moline_weather = $this->client->getWeatherReport(‘KMLI’);
$this->assertIsA($moline_weather, ‘stdClass’);
}
}

因為WeatherReport實際上并不是你程序中定義的類, SoapClient都象stdClass的實例化一樣的返回所有的對象。這時你也可以獲得返回對象的屬性的值。

class ProxyTestCase extends UnitTestCase {
function TestGetWeatherReport() {
$moline_weather = $this->client->getWeatherReport(‘KMLI’);
$this->assertIsA($moline_weather, ‘stdClass’);
$weather_tests = array(
‘timestamp’ => ‘String’
,’station’ => ‘stdClass’
,’phenomena’ => ‘Array’
,’precipitation’ => ‘Array’
,’extremes’ => ‘Array’
,’pressure’ => ‘stdClass’
,’sky’ => ‘stdClass’
,’temperature’ => ‘stdClass’
,’visibility’ => ‘stdClass’
,’wind’ => ‘stdClass’
);
foreach($weather_tests as $key => $isa) {
$this->assertIsA($moline_weather->$key,
$isa,
“$key should be $isa, actually [%s]”);
}
}
}

上面的代碼創(chuàng)建了屬性和返回類型的映射。你可以迭代這些預(yù)期值的列表,并使用assertIsA()驗證正確的類型。當然你以可以同樣的驗證其他的集合對象。

class ProxyTestCase extends UnitTestCase {
function TestGetWeatherReport() {
// continued ...
$temp = $moline_weather->temperature;
$temperature_tests = array(
‘a(chǎn)mbient’ => ‘Float’
,’dewpoint’ => ‘Float’
,’relative_humidity’ => ‘Integer’
,’string’ => ‘String’
);
foreach($temperature_tests as $key => $isa) {
$this->assertIsA($temp->$key,
$isa,
“$key should be $isa, actually [%s]”);
}
}
}

上面的方法輸出的實際效果如下：

stdClass Object
(
[timestamp] => 2005-02-27T13:52:00Z
[station] => stdClass Object
(
[icao] => KMLI
[wmo] => 72544
[iata] =>
[elevation] => 179
[latitude] => 41.451
[longitude] => -90.515
[name] => Moline, Quad-City Airport
[region] => IL
[country] => United States
[string] => KMLI - Moline, Quad-City Airport, IL, United States @ 41.451’N -90.515’W 179m
)
// ...
[temperature] => stdClass Object
(
[ambient] => 0.6
[dewpoint] => -2.8
[relative_humidity] => 78
[string] => 0.6c (78% RH)
)
// ...
)
