C# 发送Http协议模拟 Post Get请求

1.参数 paramsValue的格式要和 Reques.ContentType一致，

如果 contentype "application/x-www-form-urlencoded" 表单类型，那么参数为 a=1&b=2 形式

如果。。。 "application/json" json 类型那么参数就为 "{a:1,b:2}" 格式

2.可以添加自定义header, add（key,value）

接受获取header Request.Headers.Get(key)

 1 public static string HttpGet(string url)
 2        { 
 3            string result=string.Empty;
 4            try
 5            {
 6                HttpWebRequest wbRequest = (HttpWebRequest)WebRequest.Create(url);
 7                wbRequest.Method = "GET";
 8                HttpWebResponse wbResponse = (HttpWebResponse)wbRequest.GetResponse();
 9                using (Stream responseStream = wbResponse.GetResponseStream())
10                {
11                    using (StreamReader sReader = new StreamReader(responseStream))
12                    {
13                        result = sReader.ReadToEnd();
14                    }
15                }
16            }
17            catch (Exception ex)
18            { 
19            
20            }
21            return result;
22        }

HttpGet

 1  public static string HttpPost(string url, string paramData, Dictionary<string, string> headerDic = null)
 2        {
 3            string result = string.Empty;
 4            try
 5            {
 6                HttpWebRequest wbRequest = (HttpWebRequest)WebRequest.Create(url);
 7                wbRequest.Method = "POST";
 8                wbRequest.ContentType = "application/x-www-form-urlencoded";
 9                wbRequest.ContentLength = Encoding.UTF8.GetByteCount(paramData);
10                if (headerDic != null && headerDic.Count > 0)
11                {
12                    foreach (var item in headerDic)
13                    {
14                        wbRequest.Headers.Add(item.Key, item.Value);
15                    }
16                }
17                using (Stream requestStream = wbRequest.GetRequestStream())
18                {
19                    using (StreamWriter swrite = new StreamWriter(requestStream))
20                    {
21                        swrite.Write(paramData);
22                    }
23                }
24                HttpWebResponse wbResponse = (HttpWebResponse)wbRequest.GetResponse();
25                using (Stream responseStream = wbResponse.GetResponseStream())
26                {
27                    using (StreamReader sread = new StreamReader(responseStream))
28                    {
29                        result = sread.ReadToEnd();
30                    }
31                }
32            }
33            catch (Exception ex)
34            { }
35          
36            return result;
37        }
