有谁知道如何转换上传文件的内容（InMemoryUploadedFile) 在 Django2 中转换为字符串？
我想知道下面的内容怎么写convert2string():
uploaded_file = request.FILES['file']
my_xml = convert2string(uploaded_file) # TODO write method(convert to xml string)
obj = MyObject()
parser = MyContentHandler(obj)
xml.sax.parseString(my_xml, parser) # or xml.sax.parse(convertType(uploaded_file), parser)
Try str(uploaded_file.read())转换InMemoryUploadedFile to str
uploaded_file = request.FILES['file']
print(type(uploaded_file)) # <class 'django.core.files.uploadedfile.InMemoryUploadedFile'>
print(type(uploaded_file.read())) # <class 'bytes'>
print(type(str(uploaded_file.read()))) # <class 'str'>
UPDATE-1
假设您正在上传文本文件（.txt,.json等）如下，
my text line 1
my text line 2
my text line 3
那么你的观点就像，
def my_view(request):
uploaded_file = request.FILES['file']
str_text = ''
for line in uploaded_file:
str_text = str_text + line.decode() # "str_text" will be of `str` type
# do something
return something
