django - 如何将 InMemoryUploadedFile 的内容转换为字符串

Question

有谁知道如何将 Django2 中上传文件( InMemoryUploadedFile )的内容转换为字符串？

我想知道下面的怎么写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)

试试 str(uploaded_file.read())转换 InMemoryUploadedFile至 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'>

假设您正在上传如下文本文件( .txt 、 .json 等)，

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
