如何将InMemoryUploadedFile的内容转换为字符串

Question

有没有人知道如何将Django2中上传文件（InMemoryUploadedFile）的内容转换为字符串？

我想知道如何编写以下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)

Answer 1

尝试str(uploaded_file.read())将InMemoryUploadedFile转换为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'>

的 UPDATE-1
假设您要上传文本文件（.txt，.json等），如下所示，

my text line 1
my text line 2
my text line 3

然后你的观点就像，

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

Answer 2

file_in_memory-> InMemoryUploadedFile

file_in_memory.read().decode() -> txt output
