Having had good luck with the usual example code and openweathermap.com, I turned my MKR 1010 Wifi onto magicseaweed.com. And am getting an error back from the server that I cannot figure out. It seems to be telling me that the API URL has moved, but the link it provides back is the same one I have been using. Relevant code snips and API response follow below. Any advice appreciated. Thanks

Code snips:

In init()
WiFiClient client;
...
const char server[] = "api.magicseaweed.com";
String apiKey = SECRET_APIKEY;
....

In loop()
... after checking the wifi is till up and all that ...
Serial.println("Attempting to connect to server...");
  // if there's a successful connection:
  if (client.connect(server, 80)) {                                         
    Serial.println("connecting...");                                         
   
    client.println("GET /api/"  + apiKey + "/forecast/?spot_id=402 HTTP/1.1");
    client.println("Host: api.magicseaweed.com");
    client.println("User-Agent: ArduinoWiFi/1.2.1");
    client.println("Connection: close");
    client.println();

    Serial.println("Request Sent...");

... etc etc... and a check for a timeout then the usual example code for reading from the client...


This is what comes back:

is http supported on the server? doesn't t require https?

It doesn't seem to? (Please pardon the following noob-ness):

- Their API URL examples don't use it. https://magicseaweed.com/developer/forecast-api
- I can test the API URL in browswer without https and it responds fine
- at quick email to tech support at magic seaweed asking if I needed SSL or the like did not garner an "oh yea!"

However, since I'm a wandering mechanical engineer who wouldn't know how to change my code over to try HTTPS, how would I do it? I presume that "HTTP/1.1" there at the end needs altering, but to what?

Thanks again.

There is a slight discrepancy in the host name. See if changing "api.magicseaweed.com" to "magicseaweed.com". There are two lines of concern.

Code: [Select]
const char server[] = "api.magicseaweed.com";
client.println("Host: api.magicseaweed.com");

I was just about to type "tried it already before posting original question," but obviously I failed to try it properly, as when I just did it again it seems to work. Sigh...

Thanks for the help!
