如何在webservicex Web服务上调用GetWeather方法？

问题描述 投票：0回答：1

在阅读下面的输出for a script to get the weather时，MemberType描述了每个API的WSDL？

更广泛的问题是，从powershell，我如何知道我可以调用哪些方法？而且，它们是如何被调用的？

具体来说，这种方法：

GetWeather Method string GetWeather(string CityName, string CountryName)

然而，当我尝试调用该方法时，我得到：Data Not Found。为什么？调用该方法的正确方法是什么？我需要先调用另一种方法吗？

在.NET上使用Windows，希望得到天气：

我有的脚本：

$url = "http://www.webservicex.net/globalweather.asmx?wsdl"
$webservicex = New-WebServiceProxy -Uri $url -namespace WebServiceProxy -Class GlobalWeatherSoap
$webservicex | gm
$webservicex.GetCitiesByCountry("Netherlands")
$webservicex.GetWeather("Netherlands","Woensdrecht")

你基本上已经自己回答了这个问题。 Get-Member向您展示了如何调用该方法。 GetWeather(string CityName, string CountryName)。因此，您必须首先将CityName指定为字符串，然后将CountryName指定为字符串。

而不是$webservicex.GetWeather("Netherlands","Woensdrecht")这将是$webservicex.GetWeather("Woensdrecht","Netherlands")。

GetCitiesByCountry输出表明，国家和城市都是有效的。

输出Data Not Found是网络服务的响应，即方法工作正常，但网络服务无法找到这个城市的天气。您可以使用HTTP GET request验证您的浏览器。

不幸的是，似乎网络服务无法找到任何城市的天气。 Imo web服务坏了。 ;）
