I am working on a project where my project mate is sending me a JSON file in a API response like this-

DateCreation : "24/02/2023 08:25" DeathCertificate : "b'/9j/4AAQSkZJRgABAQEASABIAAD/7QA4UGhvdG9zaG9wIDM DeathCertificateN : "xn6n2j7h.jpg" IdExecutorN : "tmmz61dl.png" IdExecutorP : "b'iVBORw0KGgoAAAANSUhEUgAAAoAAAAHgCAMAAAF1CBxAAAA IdRequest : 49

She is using Python to encode the file to binary and then base64 with these code-

file = open(os.path.join(UPLOADS_PATH,"Request", requestData[0][1]), 'rb')
file_read = file.read()
IdExecutorP = base64.encodebytes(file_read)

I am using this code in my HTTP request in Javascript to get the file:

request.onreadystatechange = () => {
                if (request.readyState == 4 && request.status === 200) {
                    let reqdata = JSON.parse(request.response)
                    const dcbase64= [reqdata[0].DeathCertificate];
                    const dcname= reqdata[0].DeathCertificateN;
                    const exbase64= reqdata[0].IdExecutorP;
                    const exname= reqdata[0].IdExecutorN;
                    decoded_file = atob(dcbase64);
                    blob = new Blob([decoded_file], {type: 'image/png'});
                }
            };

But I am getting the error- enter image description here

I am not sure where the exact problem is... If anyone can help... that would be great!

  • The problem is that your colleague just seems to have done `str(IdExecutorP)` when stuffing the base 64 result into JSON, so you get `b'...'` as part of the result. See the duplicate above… – deceze Feb 24 '23 at 10:38
