Question

如何在.net中模拟post方式提交json数据

Answer 1

其实百度一下 “C#调用webapi” 就行，给你来一个例子吧。
这个使用HttpWebRequest 方式，还可以用HttpClient方式。
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, 0, buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
return reader.ReadToEnd();
}
}
