c# - 通过 PowerShell 将多个查询参数传递给 WebService

Question

我像这样通过 PowerShell 调用网络服务 GET 方法:

$result = Invoke-WebRequest -Uri https://localhost/MyApi/Foo/blahA/blahB?three=testing&four=2015-09-18T06:45:29.5199432Z

但是，这给了我以下错误:

The ampersand (&) character is not allowed. The & operator is reserved for future use; wrap an ampersand in double quotation marks ("&") to pass it as part of a string.

• CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
• FullyQualifiedErrorId : AmpersandNotAllowed

如果重要的是我的 WebAPI 代码和路由(该方法有两个必需参数和 3 个可选参数):

[HttpGet, ActionName("Foo")]
public string Foo(string one, string two, 
       string three = null, DateTime? four = null, int five = null)
{
    //do stuff
    //return some string
}
...
routes.MapHttpRoute(
           name: "Foo",
           routeTemplate: "Foo/{one}/{two}",
           defaults: new { controller = "Testing", action = "Foo" }
           );

一些事情，您应该将您的 URI 括在双引号中:

$result = Invoke-WebRequest -Uri "https://localhost/MyApi/Foo/blahA/blahB?three=testing&four=2015-09-18T06:45:29.5199432Z"

其次，你的url一般看起来不对，试试

$result = Invoke-WebRequest -Uri "https://localhost/MyApi/Foo?one=blahA&two=blahB&three=testing&four=2015-09-18T06:45:29.5199432Z"
