C# url接口调用

方法一：

TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0);
string sjc= Convert.ToInt64(ts.TotalMilliseconds).ToString();

using (WebClient client = new WebClient())
{
byte[] response = client.UploadValues("http://yyopenapi.renrenbuyu.com/dd373/pay",
new NameValueCollection()
{
{ "UserIDS", "" },
{ "startDate", "2017-04-01 11:17" },
{ "endDate", "2017-04-02 11:17" },
{"cpsID","1"},
{"page","1"},
{"row","20"},
{"appid","1021"},
{"timestamp",sjc},
{"sign",Globals.MD5(sjc+"900cc6ded5bcd67f524200c5904135i7")}
});
string result = System.Text.Encoding.UTF8.GetString(response);
}

方法二：

//string url = "http://openapi.renrenbuyu.com/dd373/ticket?CdKeyS=acdqsd2&startDate='2017-04-01 11:17'&endDate='2017-04-02 11:17'&cpsID=1&page=1&row=20";
//WebRequest wRequest = WebRequest.Create(url);
//wRequest.Method = "GET";
//wRequest.ContentType = "text/html;charset=UTF-8";
//WebResponse wResponse = wRequest.GetResponse();
//Stream stream = wResponse.GetResponseStream();
//StreamReader reader = new StreamReader(stream, System.Text.Encoding.UTF8);
//string str = reader.ReadToEnd(); //url返回的值
//reader.Close();
//wResponse.Close();

方法三：

//string url = "http://openapi.renrenbuyu.com/dd373/ticket";

//string CdKeyS = "acdqsd2";
//DateTime startDate = Convert.ToDateTime("2017-04-01 11:17");
//DateTime endDate = Convert.ToDateTime("2017-04-02 11:17");
//int cpsID = 1;
//int page = 1;
//int row = 20;

//object[] obj = new object[6];
//obj[0] = CdKeyS;
//obj[1] = startDate;
//obj[2] = endDate;
//obj[3] = cpsID;
//obj[4] = page;
//obj[5] = row;
//object result = WSHelper.InvokeWebService(url, "AddRecord", obj);
