从Powershell调用ASMX

debugcn 发表于 Dev

知道不多

我有一个简单的asmx Web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这样称呼它

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名称空间来访问Person类。

有没有一种更好的方式来访问Person类而不使用诸如WebServiceProxy1calhost_10875_WebService1_asmx之类的有趣的东西？

我可以从$ proxy对象中发现Person类吗？

编辑：

我将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

但是现在我得到一个错误

只需更改此行：

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

对此：

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

该-Namespace参数指定将在其中生成WSDL中的类型的名称空间，因此，如果您的WSDL声明了该Person类型，则它将在该名称空间中可用。该-Class参数默认指定代理类名称"MyClass" + random（类似于名称空间）。您通常不关心代理人~~类或其名称，因此您只需不指定此参数即可将其保留为默认值~~名称，它实际上可以是任何有效的类名称，但是您需要将其与一起指定-Namespace。

来自PowerShell的完整演示电话：

$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);
