android studio 2.2.3 http post to flask server

Note that, to contact the server, we will need to obtain the local IP address of the machine that is running the Flask server. Below at figure 1 is an example of the expected result when testing with Postman.įigure 1 – Testing the Flask server with Postman. Note that you can use a tool such as Postman to send a request to the server, making sure it is working correctly before trying to integrate with OBLOQ. I will use port 8090 but you can user another, as long as it is not being used by other application. As IP, we pass the string ‘0.0.0.0’, which means the server should listen on all the available interfaces of the machine.

We will finish the handling function implementation by returning a “Received” string to the client.įinally, we start our server by calling the run method on our app object, passing as input the IP address and the port where it should be listening for incoming requests. We do it by accessing the data and headers members of the request object we have imported in the beginning of the code. We will print the body of the request and then the headers. The route handling function will be very simple. We will have a single route which will only listen to HTTP POST requests. Then, we need to create an instance of the Flask class, which we will use to configure the routes of our server.

So, we will need the Flask class, to setup the server, and the request object, which allows to access the body and headers of the received request. The first thing we need to do is importing the functionality we will need.

Please check this previous post for the connection diagram. In order to interact with OBLOQ, we will be using a Serial to USB converter and the Arduino IDE serial monitor. For a detailed tutorial on how to send HTTP POST requests with OBLOQ, please check here. In this tutorial we will check how to send a HTTP POST from OBLOQ to a Python Flask server.
