Question

我有一个简单的asmx网络服务

public class WebService1 : System.Web.Services.WebService {

    [WebMethod]
    [ScriptMethod(UseHttpGet=true)]
    public string HelloWorld(Person person) {
        return "Hello World " + person.FirstName + " " + person.LastName;
    }
}

public class Person {
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

我从powershell这样称呼

cls
$proxy = New-WebServiceProxy -Uri 'http://localhost:10875/WebService1.asmx' -UseDefaultCredential
$person = new-object ("Microsoft.PowerShell.Commands.NewWebserviceProxy.AutogeneratedTypes.WebServiceProxy1calhost_10875_WebService1_asmx.Person")
$person.FirstName = "foo"
$person.LastName = "bar"

$s = $proxy.HelloWorld($person)
Write-Host $s

但是我不喜欢有趣的命名空间来访问Person类。

有没有更好的方法来访问Person类而不使用像WebServiceProxy1calhost_10875_WebService1_asmx这样有趣的东西？

我可以从$ proxy对象中发现Person类吗？

编辑：

我将我的powershell代码更改为

$proxy = New-WebServiceProxy -Uri 'http://localhost:10875/WebService1.asmx' -Namespace "com.abhi" -Class "Proxy" -UseDefaultCredential
$proxy | get-member -type method
$person = new-object ("com.abhi.Proxy.Person")
$person.FirstName = "foo"
$person.LastName = "bar"

$s = $proxy.HelloWorld($person)
Write-Host $s

但现在我收到错误

Answer 1

只需更改此行：

$person = new-object ("com.abhi.Proxy.Person")

到此：

$person = new-object ("com.abhi.Person")

-Namespace参数指定将生成WSDL中的类型的名称空间，因此如果您的WSDL声明Person类型，它将在该名称空间中可用。 -Class参数指定代理类名，默认为"MyClass" + random（类似于命名空间）。您通常不关心代理~~类或其名称，因此您可以通过简单地不指定此参数~~名称将其保留为默认值，它实际上可以是任何有效的类名，但是您需要与-Namespace一起指定。

来自PowerShell的完整演示调用：

$proxy = New-WebServiceProxy -uri "http://localhost:57633/WebSite1/Service.asmx?WSDL" -namespace "com.example" -class "MyProxyClass"

$person = New-Object "com.example.Person";
$person.FirstName = "MyFirstName";
$person.LastName = "MyLastName";

$proxy.HelloWorld($person);

Answer 2

我解决了问题，虽然是以一种弯曲的方式。

上述方法继续给我错误。所以我做的是我在我的网络服务中创建了一个方法，如

[WebMethod]
[ScriptMethod(UseHttpGet=true)]
public Person GetEmptyPerson() {
    return new Person();
}

现在而不是在我的客户端代码中调用new。我只是调用此方法并获取Person对象。这有效，但需要额外往返服务器。

反正。我的代码不需要超强性能，因此额外调用的开销很好。

从Powershell调用ASMX
