bodyStr, new TypeReference<TreeMap<String, String>>() { }

这是一个使用 Jackson 序列化库将 JSON 字符串转换为 TreeMap<String, String> 对象的代码片段。其中，bodyStr 是一个 JSON 字符串，TypeReference<TreeMap<String, String>> 是一个 Jackson 类型引用，用于指定要序列化的目标类型。在这个例子中，我们希望将 JSON 字符串转换为一个 TreeMap 对象，其中键和值都是字符串类型。

可以定义一个实体模型来接收 x-www-form-urlencoded 格式的参数。根据你提供的参数，可以定义如下的实体模型：

public class InventoryCheckRequest
{
    public string EchoToken { get; set; }
    public string Password { get; set; }
    public string PrimaryLangID { get; set; }
    public string TimeStamp { get; set; }
    public string UserName { get; set; }
    public string Version { get; set; }
    public POS POS { get; set; }
    public HotelReservations HotelReservations { get; set; }
}

public class POS
{
    public Source Source { get; set; }
}

public class Source
{
    public RequestorID RequestorID { get; set; }
}

public class RequestorID
{
    public string ID { get; set; }
    public string Type { get; set; }
}

public class HotelReservations
{
    public HotelReservation HotelReservation { get; set; }
}

public class HotelReservation
{
    public RoomStay RoomStay { get; set; }
    public ResGlobalInfo ResGlobalInfo { get; set; }
}

public class RoomStay
{
    public RoomTypes RoomTypes { get; set; }
    public RatePlans RatePlans { get; set; }
    public GuestCounts GuestCounts { get; set; }
    public BasicPropertyInfo BasicPropertyInfo { get; set; }
}

public class RoomTypes
{
    public RoomType RoomType { get; set; }
}

public class RoomType
{
    public string RoomTypeCode { get; set; }
}

public class RatePlans
{
    public RatePlan RatePlan { get; set; }
}

public class RatePlan
{
    public string RatePlanCode { get; set; }
}

public class GuestCounts
{
    public List<GuestCount> GuestCount { get; set; }
}

public class GuestCount
{
    public string AgeQualifyingCode { get; set; }
    public int Count { get; set; }
}

public class BasicPropertyInfo
{
    public string HotelCode { get; set; }
}

public class ResGlobalInfo
{
    public int RoomCount { get; set; }
    public string MemberLevel { get; set; }
    public TimeSpan TimeSpan { get; set; }
}

public class TimeSpan
{
    public DateTime End { get; set; }
    public DateTime Start { get; set; }
}

在控制器中，可以使用以下代码将 x-www-form-urlencoded 格式的参数转换成实体模型：

using System;
using System.IO;
using System.Net;
using System.Text;
using System.Xml.Serialization;
using Microsoft.AspNetCore.Mvc;

public class TestController : Controller
{
    [HttpPost]
    public IActionResult ReceiveMessage()
    {
        using (StreamReader reader = new StreamReader(Request.Body, Encoding.UTF8))
        {
            string bodyStr = reader.ReadToEnd();
            string message = WebUtility.UrlDecode(bodyStr.Substring(8));
            // 将 message 转换成实体模型
            XmlSerializer serializer = new XmlSerializer(typeof(InventoryCheckRequest));
            using (StringReader stringReader = new StringReader(message))
            {
                InventoryCheckRequest request = (InventoryCheckRequest)serializer.Deserialize(stringReader);
                // 对实体模型进行处理
            }
            return Ok();
        }
    }
}

在上面的代码中，使用了 XmlSerializer 来将 XML 格式的字符串转换成实体模型。需要注意的是，实体模型中的 DateTime 类型需要在 XML 中使用 ISO 8601 格式表示。

gateway 2.2.5.RELEASE Mono<Void> filter 怎么拦截post请求 并添加参数

可以通过实现GatewayFilter接口来拦截post请求，并在请求中添加参数。

以下是一个示例代码，你可以在其中编写自己的逻辑：

@Component
public class CustomGatewayFilter implements GatewayFilter {

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();
        ServerHttpRequest.Builder builder = request.mutate();
        if (request.getMethod() == HttpMethod.POST) {
            // 添加参数
            MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<>();
            queryParams.add("param1", "value1");
            queryParams.add("param2", "value2");

            // 替换请求体
            Flux<DataBuffer> body = exchange.getRequest().getBody();
            String bodyStr = DataBufferUtils.join(body).block().toString(StandardCharsets.UTF_8);
            bodyStr += "&" + URLEncodedUtils.format(queryParams, StandardCharsets.UTF_8);
            byte[] bytes = bodyStr.getBytes(StandardCharsets.UTF_8);
            DataBuffer buffer = exchange.getResponse().bufferFactory().wrap(bytes);
            builder = builder.method(request.getMethod())
                    .headers(httpHeaders -> {
                        httpHeaders.addAll(request.getHeaders());
                    })
                    .body(Mono.just(buffer));

            // 设置Content-Type
            exchange.getResponse().getHeaders().setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        }
        ServerHttpRequest newRequest = builder.build();
        return chain.filter(exchange.mutate().request(newRequest).build());
    }
}

此过滤器将会在请求为POST方法时，添加两个参数param1和param2，并将参数拼接到请求体中。最后将请求体重新封装，并设置Content-Type为application/x-www-form-urlencoded。你可以根据自己的需要，修改这个过滤器的代码逻辑。
