python - Reciving JSON with FastAPI-backend

Question

I have a little problem with sending JSON from my frontend to my backend and reading it there. At first the easy part, in my index.html I read what's written in some fields and pass it to var inputs

<script type="text/javascript">
    function get_inputs()
    {
        var inputs =
            {
                T_0 : document.getElementById("a").value,
                E_A : document.getElementById("b").value,
                           }
        backend_test(inputs)
        console.log("input:" + JSON.stringify(inputs))
        return inputs
    }
</script>

Answer 1

You should convert values to integer.

Your model expects integers.

class Liste(BaseModel):
    T_0: int
    E_A: int

Which means you should send like this

{"T_0": int,"E_A": int}

But in your current situation, you are sending string instead of int.

Convert it to int using Number or parseInt then it should work.

Change your request method to post.

type: 'POST'

Also your change your method to post on your server side.

@app.post("/compute")
