我正在尝试使用Falcon框架(python)实现POST请求以上传文件。
我已经使用falcon-multipart来进行multipart/form-data的操作,这使我可以在cgi.FieldStorage()中以二进制格式检索文件,但是现在,我需要将该文件写入目录为原始扩展名。
这是我正在使用的代码。
app.py:
import falcon
from .files import Resource
from falcon_multipart.middleware import MultipartMiddleware
api = application = falcon.API(middleware=[MultipartMiddleware()])
files = Resource()
api.add_route('/files', files)
files.py:
import io
import os
import shutil
import falcon
import json
class Resource(object):
_storage_path = './uploaded_files'
def on_post(self, req, resp):
"""
POST METHOD
"""
# Retrieve file extension
ext = req.get_param('extension')
# Retrieve input_file
input_file = req.get_param('file')
# Read file as binary
raw = input_file.file.read()
# Retrieve filename
filename = input_file.filename
# Define file_path
file_path = os.path.join(self._storage_path, filename)
# Write to a temporary file to prevent incomplete files from
# being used.
temp_file_path = file_path + '~'
# Finally write the data to a temporary file
with open(temp_file_path, 'wb') as output_file:
shutil.copyfileobj(raw, output_file)
# Now that we know the file has been fully saved to disk
# move it into place.
os.rename(temp_file_path, file_path)
resp.status = falcon.HTTP_201
最佳答案
我必须学习 cgi
这是我使用的实现:
def on_post(self, req, resp):
"""
POST METHOD
"""
# Retrieve input_file
input_file = req.get_param('file')
# Test if the file was uploaded
if input_file.filename:
# Retrieve filename
filename = input_file.filename
# Define file_path
file_path = os.path.join(self._storage_path, filename)
# Write to a temporary file to prevent incomplete files
# from being used.
temp_file_path = file_path + '~'
open(temp_file_path, 'wb').write(input_file.file.read())
# Now that we know the file has been fully saved to disk
# move it into place.
os.rename(temp_file_path, file_path)
resp.status = falcon.HTTP_201
关于python-3.x - Falcon和falcon-multipart + POST请求,用于上传文件,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/48940530/
