1.WebRequest方法
Post:
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 button_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.GetResponseAStream(),Encoding.UTF8)){
return reader.ReadToEnd();
}
}
2.HttpClient
Post:
private async void button_Click(object sender,EventArgs e)
{
HttpClient client = new HttpClient();
//由HttpClient发出D饿了么 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"});
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");
}
