後端伺服器請求

設定 Uri

 Uri urlthree = new Uri("http://cloud.calmcar.com/data/api/vboxpush.action");

設定byte[] 陣列

byte[] sssss = System.Text.Encoding.UTF8.GetBytes("fdsafdsafdsa");

另外新增一種byte[]與string 轉換（一般電腦程式都是按照byte[]儲存位元組）

string ssssssssss= System.Text.Encoding.UTF8.GetString(sssss);

我們一般常用的的前端 的Ajax 非同步請求

後端的請求多用於小程式，可以直接丟伺服器上執行，操作簡單

附上後端請求，可以直接copy使用

 public static string Http(Uri uri, byte[] data = null)
{
string rtnVal = "";
int tryTimes = 0;
again:
tryTimes++;
try
{
HttpWebRequest webRequest = (HttpWebRequest)System.Net.WebRequest.Create(uri);
webRequest.Method = "GET";
webRequest.ContentType = "application/x-www-form-urlencoded";
if (data != null)
{
webRequest.Method = "POST";
webRequest.ContentLength = data.Length;
Stream inputStream = webRequest.GetRequestStream();
inputStream.Write(data, 0, data.Length);
inputStream.Close();
inputStream.Dispose();
inputStream = null;
}
HttpWebResponse webResp = (HttpWebResponse)webRequest.GetResponse();
using (Stream receiveStream = webResp.GetResponseStream())
{
using (StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8))
{
rtnVal = readStream.ReadToEnd();
}
}
}
catch (Exception)
{
if (tryTimes < 1) goto again;
}
return rtnVal;
}
}
}　

多組引數傳參

byte[] sssss = System.Text.Encoding.UTF8.GetBytes({\"Action\":\"GetCarMainInfo\",\"CarId\":\"1000707\"});
