Alibaba big fish simple text message function. net core version, Ali core

Alibaba big fish hasn't provided the. net core SDK yet, but provides related APIs. The following is the implementation of. net core, which is just a simple text message sending function:

Using System; using System. collections. generic; using System. IO; using System. net; using System. security. cryptography; using System. text; using Newtonsoft. json; namespace ConsoleApp1 {public class SmsHelper {public static string Post (string url, string data, Encoding encoding) {try {HttpWebRequest req = WebRequest. createHttp (new Uri (url); req. contentType = "application/x-www-form-urlencoded; charset = ut F-8 "; req. method = "POST"; req. accept = "text/xml, text/javascript"; req. continueTimeout = 60000; byte [] postData = encoding. getBytes (data); Stream reqStream = req. getRequestStreamAsync (). result; reqStream. write (postData, 0, postData. length); reqStream. dispose (); var rsp = (HttpWebResponse) req. getResponseAsync (). result; var result = GetResponseAsString (rsp, encoding); return result;} catch (writable t Ion ex) {throw ;}} public static T Post <T> (string url, string data, Encoding encoding) {try {var result = Post (url, data, encoding ); return JsonConvert. deserializeObject <T> (result);} catch (Exception ex) {return default (T);} public static string BuildQuery (IDictionary <string, string> parameters) {if (parameters = null | parameters. count = 0) {return null;} StringBuilder query = new StringBuilder (); bool hasParam = false; foreach (KeyValuePair <string, string> kv in parameters) {string name = kv. key; string value = kv. value; // ignore the parameter if (! String. IsNullOrEmpty (name )&&!

When sending a text message:

Var parms = new Dictionary <string, string> (); parms. add (Constants. EXTEND, "123456"); parms. add (Constants. REC_NUM, "138 *********"); parms. add (Constants. SMS_FREE_SIGN_NAME, ""); parms. add (Constants. SMS_PARAM, "{\" code \ ": \" 1234 \ ", \" product \ ": \" \ "}"); parms. add (Constants. SMS_TEMPLATE_CODE, "sms_0000000"); var req = SmsHelper. sendSms ("http://gw.api.taobao.com/router/rest", "appKey", "appSecret", DateTime. now, parms );
