如何在 webservicex 网络服务上调用 GetWeather 方法? [英] how to call GetWeather method on webservicex web service?
问题描述
阅读下面的输出时，对于获取天气的脚本，MemberType 根据 WSDL?
When reading the output below, for a script to get the weather, the MemberType describes the API per the WSDL?
更广泛的问题是，从 powershell 中，我如何知道我可以调用哪些方法?而且，它们是如何调用的?
The broader question is, from powershell, how do I know which methods I can invoke? And, how are they invoked?
具体来说，这个方法:
GetWeather 方法 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?我需要先调用另一个方法吗?
Yet when I try to invoke that method I get: Data Not Found. Why? What's the correct way to call that method? Do I need to call another method first?
在 Windows 上使用 .NET，希望了解天气:

我拥有的脚本:
(New-Object System.Net.WebClient).Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
$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")
推荐答案
基本上你自己已经回答了这个问题.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.
You basically answered the question already by yourself. Get-Member shows you how to invoke the method. GetWeather(string CityName, string CountryName). Thus you have to specify first the CityName as a string, and second the CountryName as a string.
代替 $webservicex.GetWeather("Netherlands","Woensdrecht") 这将是 $webservicex.GetWeather("Woensdrecht","Netherlands").
GetCitiesByCountry 输出显示国家和城市都有效.
The GetCitiesByCountry output shows, that both, the country and the city are valid.
输出 Data Not Found 是网络服务的响应，即该方法工作正常，但网络服务找不到该城市的天气.您可以使用 HTTP GET 请求.
The output Data Not Found is the response of the webservice, i.e. the method worked just fine, but the webservice could not find the weather for the this city. You can verify that your browser with a HTTP GET request.
不幸的是，网络服务似乎无法找到任何城市的天气.我的网络服务坏了.;)
Unfortunately it seems that the webservice can't find the weather for any city. Imo the webservice is broken. ;)
