Pico LTE GET Request to a Web Server using HTTP

Preparing the Webhook.site

Firstly, open the https://webhook.site link in your browser on the host machine. A unique URL will be displayed for you. Refer to the figure below to locate your unique address easily. Keep in mind that all requests sent to your unique address will be visible on the sidebar.

Since our example also reads the response of the request, we may need to create a special one to understand if Pico LTE gets it correctly. Please click Edit button on the right side of the menu, and there has to be new pop-up panel about editing the response.

Status Code: The status code is a number determined by the standards, and it expresses the successful reception of a message with the number 200.

Content Type: The content type is utilized to specify the desired message format. It can be set to "text/plain" for returning plain text or "application/json" for returning a JSON file.

Response Body: The response body refers to the desired response to be returned.

In our example, we aimed to return a success message and include the request time to the server. Once you have prepared your custom response, click the save button.

{
    "response": "Hello",
    "timeOfReq": $request.timestamp$
}

Test the Code Example

Copy the following code block into the config.json file and enter your HTTP Server information.

{
  "https":{
        "server": "YOUR_HTTP_SERVER",
        "username": "YOUR_HTTP_USERNAME",
        "password": "YOUR_HTTP_PASSWORD"
   },
}

Since Webhook.site does not need use any user name and password settings, we will only provide the host address. 'Username' and 'Password' values can be deleted. For example:

{
  "https":{
        "server": "https://webhook.site/000-****-****-****-*********",
        "username": "",
        "password": ""
   },
}

Add picoLTE.http.set_auth() line below picoLTE.network.get_pdp_ready() if you are using basic HTTP authentication with a username and password specified in the config.json file.

Run the "get.py" script that you opened in Thonny IDE. When you run the script, you should see a log similar to the log below, and you should see the new GET request in your Webhook.site dashboard.

Troubleshooting

I'm getting +CME ERROR: 703 error when reading the response.

Please increase the sleeping time before asking the Pico LTE to read response. It should be solved.
