Now, we can see bellow the full code to initialize the HTTP web server.ĮSP8266WebServer server(80) //Web server object. We will analyze the handling functions for this 2 URLs later. The other URL will also receive any number of query parameters, but will look for a specific parameter name and output a “not found” message when it is not present. The name of this URL will be genericArgs. Notice the capital “A”, which needs to be taken in consideration when accessing the URL, since it will be case sensitive. Then, our handling function will build and return a message with them. .was running via a web service call, the runtime would reply with false and the Email Component would generate a parameter not found error and return.
In the first one, we will be able to receive any number of query parameters with any name and value. In this specific case, we will define 2 URLs. We start by connecting to the WiFi network and then we define in which URLs our HTTP web server will be listening to incoming requests.įor each URL, we specify the handling function that will execute upon a request on that URL. The initializing part of the code is pretty much the same as we analysed in the previous post about setting a HTTP server in the ESP8266, so only a brief summary will be presented. Note that, through this tutorial, the terms query parameter and argument are used with the same meaning when referring to the values passed in the URL. This can be used to pass some extra information to the ESP8266, which can be read by the handling functions of the web server.
So, an example of a URL with query parameters is shown bellow.
If multiple parameters need to be passed, they should be separated with ampersands (“&”). Įach query parameter is specified in the format “ParameterName=ParameterValue”. The query parameters compose the query string and are separated from the path in the URL by a question mark (“?”). Query parameters appear at the end of the path of the URL and allow to pass additional information.

The objective of this post is to explain how to access query parameters passed in HTTP requests sent to a web server deployed in the ESP8266.
