Question

我可以运行“hello world”脚本，但是尝试运行这个sample脚本：

C:\Users\thufir\Desktop>
C:\Users\thufir\Desktop>powershell -ExecutionPolicy RemoteSigned
Windows PowerShell

PS C:\Users\thufir\Desktop>
PS C:\Users\thufir\Desktop> type .\stock.ps1
# Working example of how to use PowerShell (version >= 2) to access a web service.
$svc = New-WebServiceProxy –Uri ‘http://www.webservicex.net/stockquote.asmx?WSDL’

$svc | Get-Member  # Use Get-Member to discover the interface of a web service.
# Get stock quotes.
$svc.GetQuote(‘BA’)   # Boeing

这是政策问题吗？或者，脚本本身的问题？

也：

PS C:\Users\thufir\Desktop>
PS C:\Users\thufir\Desktop> .\hello.ps1
hi
Cannot convert value "Data Not Found" to type "System.Xml.XmlDocument". Error: "The specified node cannot be inserted
as the valid child of this node, because the specified node is the wrong type."

PS C:\Users\thufir\Desktop>
PS C:\Users\thufir\Desktop> type .\hello.ps1



echo "hi"


$proxy = New-WebServiceProxy -Uri http://www.webservicex.net/globalweather.asmx?WSDL
[xml]$response = $proxy.GetWeather("Tampa", "United States")
$response.CurrentWeather | Format-List

Answer 1

在我看来，这是您正在调用的Web服务的问题。它返回字符串＆＃34; exception＆＃34;。您的代码运行正常。

导航到网站Stock Quote Detail并运行测试我也会在那里返回异常。

Answer 2

尝试运行此操作并获得例外：

PS：14：27：35＆gt; $ quote = Invoke-RestMethod -Uri＆＃34; http://www.webservicex.net/stockquote.asmx/GetQuote?symbol=GOOGL＆＃34; -Method Get

PS：14：27：49＆GT; $ quote.string

xmlns #text
----- -----
http://www.webserviceX.NET/例外

PS：14：27：53＆GT; $ quote.string＆＃39;＃文本＆＃39;

。

Answer 3

quick and dirty输出：

#include<stdio.h>
#include<stdlib.h>

static char mem[4];

int main()
{
    int* A = (int*)(mem);

    mem[0] = 0;
    mem[1] = 1;
    mem[2] = 2;
    mem[3] = 3;

    int i;
    A[0] = 5;

    for (i = 0; i<4; i++)
    {
        printf("%d\t", mem[i]);
    }

    printf("\n");
    return 0;
}

只是在黑暗中摸索着。但是，有趣的是：）
