我有一个Flask项目在本地机器上运行良好。现在，我正在尝试将其部署在Microsoft Azure服务器（Linux 17）上，但是当我单击某个按钮时，它会给我一个错误。
@app.route('/database', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
f = request.files['file']
f.save(werkzeug.secure_filename(f.filename))
Finaldata = readFile(f.filename) # a function to read the uploaded file, request and API then process the data. Create a new file and write the output to
filename = Finaldata
@after_this_request
def remove_file(response):
try:
os.remove(f.filename)
# readDate.readerIn.close()
except Exception as error:
app.logger.error("Error removing or closing downloaded file handle", error)
return response
def download(response):
response = make_response(Finaldata)
response.headers["Content-Disposition"] = "attachment; filename=result.txt"
render_template('upload.html', filename=filename)
return response
return render_template('upload.html', filename = filename)
我的HTML代码：
<form action = "/database" method = "POST"
enctype = "multipart/form-data" class="w3-button w3-light-grey w3-padding-large w3-margin-top">
<input type = "file" name = "file" />
<input type = "submit"/>
</form>
浏览器上的错误消息：
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
