1.WebRequest方式
private void button1_Click(object sender, EventArgs e) ? ? ? ? { ? ? ? ? ? ?string ss= HttpPost("http://localhost:41558/api/Demo/PostXXX", "{Code:\"test089\",Name:\"test1\"}"); ? ? ? ? } ? ? ? ? public static string HttpPost(string url, string body) ? ? ? ? { ? ? ? ? ? ? //ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult); ? ? ? ? ? ? Encoding encoding = Encoding.UTF8; ? ? ? ? ? ? HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); ? ? ? ? ? ? request.Method = "POST"; ? ? ? ? ? ? request.Accept = "text/html, application/xhtml+xml, */*"; ? ? ? ? ? ? request.ContentType = "application/json"; ? ? ? ? ? ? ? ? ? ? byte[] buffer = encoding.GetBytes(body); ? ? ? ? ? ? request.ContentLength = buffer.Length; ? ? ? ? ? ? request.GetRequestStream().Write(buffer, 0, buffer.Length); ? ? ? ? ? ? HttpWebResponse response = (HttpWebResponse)request.GetResponse(); ? ? ? ? ? ? using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) ? ? ? ? ? ? { ? ? ? ? ? ? ? ? return reader.ReadToEnd(); ? ? ? ? ? ? } ? ? ? ? }
Get：
private void button1_Click(object sender, EventArgs e) ? ? ? ? { ? ? ? ? ? ? string ss = HttpGet("http://localhost:41558/api/Demo/GetXXX?Name=北京"); ? ? ? ? } ? ? ? ? public static string HttpGet(string url) ? ? ? ? { ? ? ? ? ? ? //ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult); ? ? ? ? ? ? Encoding encoding = Encoding.UTF8; ? ? ? ? ? ? HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); ? ? ? ? ? ? request.Method = "GET"; ? ? ? ? ? ? request.Accept = "text/html, application/xhtml+xml, */*"; ? ? ? ? ? ? request.ContentType = "application/json"; ? ? ? ? ? ? ? ? ? ? ? ? HttpWebResponse response = (HttpWebResponse)request.GetResponse(); ? ? ? ? ? ? using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) ? ? ? ? ? ? { ? ? ? ? ? ? ? ? return reader.ReadToEnd(); ? ? ? ? ? ? } ? ? ? ? }
2.HttpClient 方式
Post:
private async void button2_Click(object sender, EventArgs e) { ? ? ?HttpClient client = new HttpClient(); ? ? ?//由HttpClient发出Delete Method ? ? ?HttpResponseMessage response = await client.DeleteAsync("http://localhost:41558/api/Demo"+"/1"); ? ? ?if (response.IsSuccessStatusCode) ? ? ? ? ?MessageBox.Show("成功"); } private async void button3_Click(object sender, EventArgs e) { ? ? ?//创建一个处理序列化的DataContractJsonSerializer ? ? ?DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(People)); ? ? ?MemoryStream ms = new MemoryStream(); ? ? ?//将资料写入MemoryStream ? ? ?serializer.WriteObject(ms, new People() { Id = 1, Name = "Hello ni" }); ? ? ?//一定要在这设定Position ? ? ?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(); ? ? ?//由HttpClient发出Put Method ? ? ?HttpResponseMessage response = await client.PutAsync("http://localhost:41558/api/Demo"+ "/1", content); ? ? ?if (response.IsSuccessStatusCode) ? ? ? ? ?MessageBox.Show("成功"); }
Get:
using (WebClient client = new WebClient()) { client.Headers["Type"] = "GET"; client.Headers["Accept"] = "application/json"; client.Encoding = Encoding.UTF8; client.DownloadStringCompleted += (senderobj, es) => { var obj = es.Result; }; client.DownloadStringAsync("http://localhost:41558/api/Demo"); }
