I have a issue with send pdf attached email using jspdf with ajax and django. The issue is server side views.py print(pdf_s) always retrun 'None' but client side console.log(pdf) returns binary values.
Please refer the below code which i was tried.
script.js
This is client side code. and I'm using Ajax to send data to server
function sendMail(){
getCanvas().then(function(canvas) {
console.log('Test');
var img = canvas.toDataURL("image/png",0.98);
var imgWidth = 200;
var pageHeight = 295;
var imgHeight = canvas.height * imgWidth / canvas.width;
var heightLeft = imgHeight;
var doc = new jsPDF('p', 'mm', 'a4', 'pt');
var position = 0;
doc.addImage(img, 'JPEG', 5, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
while (heightLeft >= 0) {
position = heightLeft - imgHeight;
doc.addPage();
doc.addImage(img, 'JPEG', 5, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
}
var pdf = btoa(doc.output());
console.log(pdf);
$.ajax({
type:'POST',
url:'sendmail/',
data:{
pdf_data: pdf,
csrfmiddlewaretoken: csrftoken
},
success:function(data){
console.log(data);
}
});
});
}
views.py
def SendMail(request,scan_id):
pdf_s = request.GET.get('pdf_data')
print(pdf_s)
fo = open('test.pdf','w')
fo.write(pdf_s)
fo.close()
html_content = "Test Message"
email = EmailMessage("test", html_content, "test", ["test@test.com"])
email.content_subtype = "html"
fd = open('test.pdf', 'r')
email.attach('test', fd.read(), 'application/pdf')
res = email.send()
if res:
status = 'Success'
else:
status = 'Fail'
return HttpResponse(status)
Check ajax request via browser dev tools > network. Perhaps "pdf_data" parameter does not exist.
I send file via native js.
JS
var formData = new FormData();
formData.append('file.pdf', file);
var xhr = new XMLHttpRequest();
xhr.onload = function (e) {
if (xhr.readyState === 4 && xhr.status === 200){
result=xhr.responseText;
console.log(result);
}
}
xhr.open('POST', url, true);
xhr.setRequestHeader("X-CSRFToken", csrfmiddlewaretoken);
xhr.send(formData);
Python
element_file=File(request.FILES[request.FILES.keys()[0]])
with open('file.pdf','wb+') as destination:
for chunk in element_file.chunks(): destination.write(chunk)
It's work in case if send file from local computer via input type="file"
