创建WebApi项目：
在VS工具中创建一个ASP.NET Web应用程序
选择Webapi
一个webapi项目就创建好了
这里简单的写一个post和get两种请求的方法，由于post请求参数需要参数体的形式，一般用json作为参数，这里简单创建一个实体类，放上参数，我这里就放一个，可根据项目自己设置相应的参数
注意的是，post请求的时候，json里的键值对 键的名字要和实体中的一样，过来实体接收参数会自动将json值拆分到各个对应的名字上
然后先写post方法，记得要写请求方式[HttpPost]，注意这个参数的写法
[HttpPost]
public string demo([FromBody]Contact name)
{
string nn = name.Name;
string result = string.Empty;
result = "您的参数是：" + nn;
return result;
}
Get方法可以直接获取参数，注意[HttpGet]
[HttpGet]
public string wxs(string name)
{
string result = string.Empty;
result = "{Name:\"" + name + "\"}";
return result;
}
一个简单的webapi就写完了，现在试试请求这个webapi，我这里用C#控制台应用程序写一个简单的调用
为了方便测试，我直接将这个webapi发布到了本机的IIS上
Post请求：
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{ string ss = HttpPost("http://localhost:8097/api/Contact/demo", "{\"Name\":\"zhangsan\"}"); Console.WriteLine(ss); Console.ReadLine();
} public static string HttpPost(string url, string body)
{
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, , buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
return reader.ReadToEnd();
} }
}
}
Get请求：
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{ string ss = HttpGet("http://localhost:8097/api/Contact/wxs?name=zhangsan"); Console.WriteLine(ss); Console.ReadLine();
} public static string HttpGet(string url)
{
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();
}
} }
}
