我们如何更改 firebase.functions().httpsCallable 中的 responseType

Question

Initially i was using http post method like below to generate pdf

this.httpClient.post(this.globals.constUrl + 'reportData', data, {responseType: 'blob'})

access code with subscribe the response

const myBlob: Blob = new Blob([res], {type: 'application/pdf;charset=utf-8'}); // replace the type by whatever type 

is your response

        const fileURL = URL.createObjectURL(myBlob);
        window.open(fileURL);

The above code is working fine but now i want to get it done with httpsCallable, while attempting this I am not able to change responseType as we do in post method, so PDF is not being generated Please suggest a way to get it done.

Answer 1

Callable type functions can only send data formatted as JSON. If you need to send something different, you shouldn't use a callable at all. Use a normal HTTP type function to gain full control over the response.
