前言

参考文章：

用C#进行MES系统的对接，同时要发送JSON请求。最后要从MES系统中获得相应的应答。

我期望的是能够用一个类将HTTP请求和响应处理进行封装。

---

一、引入命名空间

using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;

---

二、ApiClient类进行封装

public class ApiClient
{
    
    
    private readonly string apiUrl;
    private readonly HttpClient client;

    public ApiClient(string apiUrl)
    {
    
    
        this.apiUrl = apiUrl;
        this.client = new HttpClient();
        this.client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
    }

    public YourResponseModel SendRequest(object requestBody)
    {
    
    
        try
        {
    
    
            var jsonContent = new StringContent(JsonConvert.SerializeObject(requestBody), Encoding.UTF8, "application/json");
            HttpResponseMessage response = client.PostAsync(apiUrl, jsonContent).Result;

            if (response.IsSuccessStatusCode)
            {
    
    
                string responseContent = response.Content.ReadAsStringAsync().Result;
                return JsonConvert.DeserializeObject<YourResponseModel>(responseContent);
            }
            else
            {
    
    
                Console.WriteLine($"请求失败，状态码: {
      
      response.StatusCode}");
                return null; // 或者抛出异常，取决于您的需求
            }
        }
        catch (Exception ex)
        {
    
    
            Console.WriteLine($"发生错误: {
      
      ex.Message}");
            throw; // 重新抛出异常，以便调用者知道发生了错误
        }
    }
}

三、定义响应模型类

public class YourResponseModel
{
    
    
    public string resultCode {
    
     get; set; }
    public string resultMsg {
    
     get; set; }
    public ResultData resultData {
    
     get; set; }
}

public class ResultData
{
    
    
    public int pageNo {
    
     get; set; }
    public int totalPage {
    
     get; set; }
    public int totalSize {
    
     get; set; }
    public object[] data {
    
     get; set; }
    public int pageSize {
    
     get; set; }
}

---

四、发送请求并处理请求

class Program
{
    
    
    static void Main(string[] args)
    {
    
    
        string apiUrl = "http://10.0.0.0:8888/api";
        var apiClient = new ApiClient(apiUrl);

        var requestBody = new
        {
    
    
            docType = "MES***LB**PROCESS",
            updateType = "UPDATE",
            data = new[]
            {
    
    
                new
                {
    
    
                    mo_code = "001102982621-210",
                    vehicles_code = "FL12",
                    mes_mo_lbwp_qc = new[]
                    {
    
    
                        new
                        {
    
    
                            ng_item_code = (string)null
                        }
                    },
                    prod_stat = "1",
                    lb_id = "S5J5.24A**1603789",
                    wu_code = "20T_P40_ST08",
                    s_date = "2024-10-17T09:58:36.3847994+08:00",
                    acupoint = "10",
                    wp_code = "**XNY0**10"
                }
            }
        };

        // 使用 Task 来启动一个新的线程执行 HTTP 请求
        Task.Run(() =>
        {
    
    
            try
            {
    
    
                YourResponseModel response = apiClient.SendRequest(requestBody);
                if (response != null)
                {
    
    
                    Console.WriteLine($"Response received: {
      
      response.resultCode} - {
      
      response.resultMsg}");
                }
            }
            catch (Exception ex)
            {
    
    
                Console.WriteLine($"发生错误: {
      
      ex.Message}");
            }
        }).Wait(); // 等待任务完成，如果不需要等待，可以去掉 .Wait()
    }
}
