C#后端调用地址接口

string url="地址信息";

//初始化url

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

request.method ="Post";//请求类型

request.ContentType="application/json";//请求内容类型

//写入流

using(StreamWriter dataStream = new StreamWriter(request.GetRequestStream))

{

dataStream.Close();

}

//获取响应信息

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

string encoding =response.ContentEncoding;

if(encoding==null || encoding.Length<1) 

{

encoding = "UTF-8";

}

//读取流

StreamReader reader = new StreamReader(response.GetResponseStream(),Encoding.GetEncoding(encoding));

string readStr = reader.ReadToEnd();//读取接口返回的信息
