How to Delete an SMS in C/C++

The simplest way to send SMS from C/C++ is to use the built in HTTP/Rest SMS api of Ozeki SMS Gateway. When you use this API, you will send SMS messages by issuing a HTTP Post request to the SMS gateway. The HTTP Post request will contain a message formatted in json format. The SMS gateway will send this SMS to the recipient phone, and it will return a HTTP 200 OK response to your request.

C/C++ code to recive sms from mobile

The C/C++ sms code sample below demonstrates how you can receive SMS using the http rest sms api of Ozeki SMS Gateway using the C++ Ozeki.Libs.Rest library. This library is provided to you free of charge, and you may use it and modify it in any of your projects.

DeleteSms.cpp 

#include <iostream>
#include <string>
#include "Ozeki.Libs.Rest.h"

using namespace std;

int main()
{
    //Function to create unique identifier for each messages
    srand((unsigned)time(0));

    Configuration configuration;
    configuration.Username = "http_user";
    configuration.Password = "qwe123";
    configuration.ApiUrl = "http://127.0.0.1:9509/api";

    Message msg;
    msg.ID = "3587663a-f85a-4332-bb08-8cd58a772d20";

    MessageApi api(configuration);

    auto result = api.Delete(Inbox, msg);

    cout << result << endl;

    return 0;
}

How to use the C/C++ sms example:

This C/C++ sms example can be used in any C or C++ application. To use it, you must add the Ozeki.Libs.Rest dll as a reference to your project. After the project reference is added, you must put the using Ozeki.Libs.Rest; directive into the header section of your C/C++ source code. This will allow you to use the classes provided by the Ozeki.Libs.Rest library. You can use the MessageApi class to delete the SMS from the SMS gateway. The SMS gateway will forward the message to you either through a wireless connection or through the Internet.

How to delete SMS using C/C++ (Quick steps)

To delete SMS using C/C++:

  1. Setup Visual Studio Community
  2. Download the DeleteSms.cpp.zip file
  3. Extract the .zip file from Downloads
  4. Open the DeleteSms.sln file in Visual Studio
  5. Launch Ozeki SMS Gateway
  6. Select http_user in the Users and applications tab
  7. Check the Message details in the Inbox
  8. Insert the ID of the SMS message into DeleteSms.cpp code
  9. Run DeleteSms.cpp to delete SMS with C/C++

Install Ozeki SMS Gateway and create an HTTP API user

To be able to send SMS from C/C++, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your C/C++ code in Visual studio. After installation, the next step is to connect Ozeki SMS Gateway to the mobile network. You can send a test sms from the Ozeki GUI to verify, that your mobile network connection works. The final step to prepare your environment is to create a HTTP sms api user. Create a user with a username of "http_user", and with a password of "qwe123" to make the example work without modification.

After the environment is setup, you can run your C/C++ code.

HTTP API url to use send sms from C/C++

To delete SMS from C/C++, your C/C++ will have to issue an HTTP request to the SMS gateway. The API url is shown below. Note that the IP address (127.0.0.1) should be replaced to the IP address of your SMS gateway. If Ozeki SMS Gateway is installed on the same computer where the C/C++ sms application is running, this can be 127.0.0.1. If it is installed on a different computer, it should be the IP address of that computer. 

http://127.0.0.1:9509/api?action=rest

HTTP authentication to use receive sms from C#

To authenticate the C# sms client, you need to send the username and password in a base64 encoded string to the server in a HTTP request. The format used is: base64(username+":"+password). In C# you can use the following code to do this encoding: 

string usernamePassword = username + ":" + password;
string usernamePasswordEncoded = base64::encode(usernamePassword);
return "Basic " + usernamePasswordEncoded;

For example, if you encode the username 'http_user' and the password 'qwe123', you will get the following base64 encoded string: aHR0cF91c2VyOnF3ZTEyMw==. To send

HTTP request to delete SMS with C/C++

To delete SMS, your C/C++ application will send an HTTP request similar to the one below. Note, that this request contains a HTTP header part and a http body part. The HTTP body is a JSON encoded data string. It contains the recipient's number and the message's text. 

POST /api?action=deletemsg HTTP/1.1
Content-Length: 73
Content-Type: application/json
Accept: application/json
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==
Host: 127.0.0.1:9509

	"folder":	"inbox",
	"message_ids":	[
		"117b03d8-f2a1-41b8-8d91-d2996a38291b"
	]
}

HTTP request header to delete SMS from C/C++

To send the SMS messages, you need to include the following lines as headers in the HTTP request. Note that we include a content type and an Authorization header. 

Content-Type: application/json
Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==

HTTP response received by the C/C++ sms example

Once the SMS gateway receives this request, it will generate a HTTP response. The HTTP response will contain a status code, to indicate whether the SMS submit request was successful or not. It will also return a JSON encoded structure to provide you useful details about the message's submission. 

HTTP/1.1 200 OK
User-Agent: OZEKI 10.3.123 (www.myozeki.com)
Content-Type: application/json; charset=utf8
