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 = ;
            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 = ;
            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
