  • 自己积累写的winfrom 操作api 类

    引用 类

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Net;
    using System.Net.Http;
    using System.Net.WebSockets;
    using Newtonsoft.Json;
    using System.Runtime.Serialization.Json;
    using System.IO;
    using System.Windows.Forms;
    

      api 在winform中的get 方法

     public static List<T> Jsonobject<T>(Uri url)
            {
    
                using (var client = new HttpClient())
                {
                    var result = client.GetStringAsync(url).Result;
                    
                    List<T> ds = JsonConvert.DeserializeObject<List<T>>(result);
                    return ds;
                }

    我在这里返回的是List<T> 泛型集合,在后台获取时声明泛型收集即可.

    api 在winfrom 中的put 方法

    public async void PueAnsy<T>(Uri uri, T t1)
            {
    
                string data = JsonConvert.SerializeObject(t1);
                DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
                MemoryStream ms = new MemoryStream();
                serializer.WriteObject(ms, t1);
                ms.Position = 0;
                HttpContent content = new StreamContent(ms);
                content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
                HttpClient client = new HttpClient();
                HttpResponseMessage response = await client.PutAsync(uri, content);
    if (response.IsSuccessStatusCode) { } else { } }

    api 在winfrom 中的Post 方法

    public async void Update<T>(T t1, Uri url)
            {
                DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
                MemoryStream ms = new MemoryStream();
                serializer.WriteObject(ms, t1); //传入model
    
                ms.Position = 0;
                HttpContent content = new StreamContent(ms);//将MemoryStream转成HttpContent
                content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
                HttpClient client = new HttpClient();
                HttpResponseMessage response = await client.PostAsync(url, content); 

    if (response.IsSuccessStatusCode) { MessageBox.Show("成功"); } }

    api 在winfrom 中的Delete 方法

    public async void Delete(Uri url)
            {
                HttpClient client = new HttpClient();
                HttpResponseMessage response = await client.DeleteAsync(url);
                if (response.IsSuccessStatusCode)
                {
                    MessageBox.Show("删除成功");
                }
                else
                {
                    MessageBox.Show("删除失败");
                }
            }

    如果delete方法 需要传入model ,参照update 方法进行修改
