Question

我有一个C＃asmx Web服务WP.asmx，它是字符串方法`Authorisation（string PMSRequest）

[ScriptMethod(UseHttpGet = true)]
[WebMethod]
public string Authorisation(string PMSRequest)

将JSON字符串反序列化为名为Details的类

class Details
    {
        public string Number { get; set; }
    }

此处：

Details obj = JsonConvert.DeserializeObject<Details>(PMSRequest)

并最终重新输入字符串。

我正在尝试通过浏览器调用它

https://example.net/WP.asmx/Authorisation?PMSRequest="{\"Number\":\"5413\"}"

强文本但是我得到一个错误

Could not cast or convert from System.String to My.Web.MyService.WP+Details

Newtonsoft.Json.JsonSerializationException: Error converting value

当我在C＃Windows Form测试应用程序中使用相同的代码时，它可以正常工作
