一、不带参数请求
/// <summary> /// POST请求不带参数 /// </summary> /// <param name="url"></param> /// <returns></returns> public static string Post(string url) { string result;//返回结果 HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; request.Method = "POST"; HttpWebResponse response = request.GetResponse() as HttpWebResponse; Stream stream = response.GetResponseStream(); using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { result = reader.ReadToEnd(); } return result; }
二、带参数 post请求
/// <summary>
/// post请求带参数
/// </summary>
/// <param name="url"></param>
/// <param name="param">参数字符串</param>
/// <returns></returns>
public static string Post(string url, string param)
{
//创建post请求
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";//请求方式post
request.ContentType = "application/json;charset=UTF-8";//链接类型
byte[] payload = Encoding.UTF8.GetBytes(param);//参数编码
request.ContentLength = payload.Length;
//发送post的请求,写入参数
Stream writer = request.GetRequestStream();
writer.Write(payload, 0, payload.Length);
writer.Close();
//接受返回来的数据
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream, Encoding.UTF8);
string value = reader.ReadToEnd();
reader.Close();
stream.Close();
response.Close();
return value;
}
