php调用web service接口(.net开发的接口)
实例代码1: try { $this-soapClientObj = new SoapClient(self::URL . '?wsdl', array('connection_timeout' = self::CONNECTION_TIMEOUT)); } catch (Exception $e) { throw new Exception($e-getMessage(), $e-getCode()); } 实例代码2: ?php header ( "
实例代码1:
try {
$this->soapClientObj = new SoapClient(self::URL . '?wsdl', array('connection_timeout' => self::CONNECTION_TIMEOUT));
} catch (Exception $e) {
throw new Exception($e->getMessage(), $e->getCode());
}
实例代码2:
header ( "Content-Type: text/html; charset=utf-8" );
/*
* 指定WebService路径并初始化一个WebService客户端
*/
$ws = "http://www.webservicex.net/globalweather.asmx?wsdl";//webservice服务的地址
$client = new SoapClient ($ws);
/*
* 获取SoapClient对象引用的服务所提供的所有方法

例子解释:
上面的代码抛出了一个异常,并捕获了它:
- 创建 checkNum() 函数。它检测数字是否大于 1。如果是,则抛出一个异常。
- 在 "try" 代码块中调用 checkNum() 函数。
- checkNum() 函数中的异常被抛出
- "catch" 代码块接收到该异常,并创建一个包含异常信息的对象 ($e)。
- 通过从这个 exception 对象调用 $e->getMessage(),输出来自该异常的错误消息
不过,为了遵循“每个 throw 必须对应一个 catch”的原则,可以设置一个顶层的异常处理器来处理漏掉的错误。

The interface is defined using the interface keyword, which only contains method signatures, which is suitable for defining behavioral norms and multiple inheritance.
