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
