C#使用GET、POST请求获取结果

小渣渣

我只演示get请求之后的结果如上：

代码如下：

httpget请求：

1. /// <summary>
   
2. /// GET请求与获取结果
   
3. /// </summary>
   
4. public static string HttpGet(string Url, string postDataStr)
   
5. {
   
6.     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr);
   
7.     request.Method = "GET";
   
8.     request.ContentType = "text/html;charset=UTF-8";
   
9. 
   
10.     HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    
11.     Stream myResponseStream = response.GetResponseStream();
    
12.     StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
    
13.     string retString = myStreamReader.ReadToEnd();
    
14.     myStreamReader.Close();
    
15.     myResponseStream.Close();
    
16. 
    
17.     return retString;
    
18. }

调用get请求：

1. static void Main(string[] args)
   
2. {
   
3.     string url = "http://www.itsvse.com/LoginHandler.aspx";
   
4.     string data = "UserName=admin&Password=123";
   
5.     string result = HttpGet(url, data);
   
6.     Console.WriteLine(result);
   
7.     Console.ReadLine();
   
8. }

复制代码

httppost请求：

1. /// <summary>
   
2. /// POST请求与获取结果
   
3. /// </summary>
   
4. public static string HttpPost(string Url, string postDataStr)
   
5. {
   
6.     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
   
7.     request.Method = "POST";
   
8.     request.ContentType = "application/x-www-form-urlencoded";
   
9.     request.ContentLength = postDataStr.Length;
   
10.     StreamWriter writer = new StreamWriter(request.GetRequestStream(),Encoding.ASCII);
    
11.     writer.Write(postDataStr);
    
12.     writer.Flush();
    
13.     HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    
14.     string encoding = response.ContentEncoding;
    
15.     if (encoding == null || encoding.Length < 1) {
    
16.         encoding = "UTF-8"; //默认编码
    
17.     }
    
18.     StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
    
19.     string retString = reader.ReadToEnd();
    
20.     return retString;
    
21. }

复制代码

调用post请求：

1. static void Main(string[] args)
   
2. {
   
3.     string url = "http://www.itsvse.com/LoginHandler.aspx";
   
4.     string data = "UserName=admin&Password=123";
   
5.     string result = HttpPost(url, data);
   
6.     Console.WriteLine(result);
   
7.     Console.ReadLine();
   
8. }
