Question

我正在尝试使用perl肥皂服务：

=begin WSDL

_IN nr $string hah
_RETURN @string hih

=cut

所以perl接受一个参数并返回一个结果数组：

wsdl看起来像这样：

测试时：

string[] test = kk.VMs("35294000");

我得到一个例外：cannot convert string to string[]。所以我将代码更改为：

    [System.Web.Services.Protocols.SoapRpcMethodAttribute("", RequestNamespace = "http://10.0.252.24/VM", ResponseNamespace = "http://10.0.252.24/VM")]
    [return: System.Xml.Serialization.SoapElementAttribute("VMsReturn")]
    public string VMs(string nr) {
        object[] results = this.Invoke("VMs", new object[] {
                    nr});
        return ((string)(results[0]));
    }

and
string test = kk.VMs("35294000");

现在返回结果。但只有第一个结果，我应该得到一个数组。

Answer 1

解决。是soap :: lite中的“功能”。而不是使用

返回数组

return @result

（这将返回带参数的错误soap回答而不是结果数组）你需要这样做：

return \@result

将返回一个soap数组，现在一切都是开箱即用的自动生成的wsdl代码。

只能从perl soap服务获得第一个结果
