I am using python 3 & I have this code, trying to get base64 out of stream and returnn as json - but not working.
stream = BytesIO() img.save(stream,format='png') return base64.b64encode(stream.getvalue()) in my view, I have:
hm =mymap() strHM = hm.generate(data) return HttpResponse(json.dumps({"img": strHM}),content_type="application/json" ) getting error is not JSON serializable. base64.b64encode(stream.getvalue()) seems giving bytes

In JavaScript there are two functions respectively for decoding and encoding Base64 strings: btoa() : creates a Base64-encoded ASCII string from a "string" of binary data ("btoa" should be read as "binary to ASCII"). atob() : decodes a Base64-encoded string ("atob" should be read as "ASCII to binary").
To convert a string into a Base64 character the following steps should be followed: Get the ASCII value of each character in the string. Compute the 8-bit binary equivalent of the ASCII values. Convert the 8-bit characters chunk into chunks of 6 bits by re-grouping the digits.

Decoding base64First, you remove any padding characters from the end of the encoded string. Then, you translate each base64 character back to their six-bit binary representation. Finally, you divide the bits into byte-sized (eight-bit) chunks and translate the data back to its original format.
In Python 3.x, base64.b64encode accepts a bytes object and returns a bytes object.
>>> base64.b64encode(b'a') b'YQ==' >>> base64.b64encode(b'a').decode() 'YQ==' You need to convert it to str object, using bytes.decode:
return base64.b64encode(stream.getvalue()).decode() If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
