将'str‘放入Djano forms.FileField()

import tempfile
from django.core.files import File

temp_file = tempfile.NamedTemporaryFile(delete=True)
temp_file.write('str'.encode())
temp_file.flush()
file_obj = File(temp_file)

# 使用file_obj进行后续操作，如保存到数据库或存储到云存储服务

import io
from django.core.files.uploadedfile import InMemoryUploadedFile

memory_file = io.BytesIO()
memory_file.write('str'.encode())
memory_file.seek(0)
file_obj = InMemoryUploadedFile(
    memory_file,
    None,
    'file.txt',
    'text/plain',
    memory_file.tell(),
    None
)

# 使用file_obj进行后续操作，如保存到数据库或存储到云存储服务

from django import forms

class MyForm(forms.Form):
    file_field = forms.FileField()

form = MyForm({'file_field': file_obj}, {'file_field': 'str.txt'})
if form.is_valid():
    # 执行表单验证通过后的操作
    pass
