Hey guys,
I wanna know correct procedure of doing HTTP post on a given URL using ESP8266 libraries.

Consider this URL. It is used to send SMS from experttexing.com by simply filling the parameters in the URL.

[url]
https://www.experttexting.com/ExptRestA ... &type=text
[/url]

Can I know how to do HTTP POST using WiFiClient library as well as HTTPClient library.
Waiting for helpful reply

I'm trying like this using WiFi client library...

Code: Select all

      client.println("POST /exptapi/exptsms.asmx/SendSMS HTTP/1.1");
      client.println("Host: www.experttexting.com");
      client.println("Connection: close");
      client.println("Content-Type: application/x-www-form-urlencoded");
      client.print("Content-Length: ");
      client.println(sttr.length());
      client.println("\r\n");
      client.println(sttr);

This is how client prints..

Code: Select all

POST /exptapi/exptsms.asmx/SendSMS HTTP/1.1
Host: www.experttexting.com
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 94


UserID=USERNAME&PWD=PASS!&APIKEY=APIKEY&FROM=DEFAULT&TO=+17133028183&MSG=MsgFromESP
Server Response....
HTTP/1.1 301 Moved Permanently

I am always getting 301 Moved Permanently as Response.. Please Help..

Hi,

that's probably because the API only supports HTTPS connections.

Take a look at the HTTPSRequest example in the Arduino IDE and try modifying this.

Ps: I hope this aren't your real login credentials in the link you posted. Otherwise remove or change them quickly and change the password.
