[英]Flask web application can't upload file
I am using the following code to upload a file to a directory on the server. 我正在使用以下代码将文件上传到服务器上的目录。 Each time I upload a file and press submit 'file' is not found in request.files.
每次我上载文件并按Submit时,request.files中都找不到。 Any ideas?
有任何想法吗?
views.py: views.py:
@app.route("/upload_file")
def upload_file(self):
return self.render_template('upload_file.html')
@app.route("/file_uploader", methods=['GET', 'POST'])
def file_uploader(self):
if request.method == 'POST':
#application gets to this if block and returns 'No file part'
if 'file' not in request.files:
flash('No file part')
return redirect(request.url)
file = request.files['file']
upload_file.html: upload_file.html:
<h2>Please select a dataset to upload.</h2>
<form method=post enctype=multipart/form-data action={{ url_for('file_uploader')}}>
<span class="btn btn-primary btn-file"> Browse <input type="file"></span>
<input type=submit class="btn btn-success" value=Upload>
</form>
I believe your issue is with your value, I'd also recommend modifying your app so it prints request.files
to clarify your response object. 我相信您的问题在于您的价值,我也建议您修改您的应用程序,以便它打印
request.files
来澄清您的响应对象。 In your jinja2 template, you should modify your code to specify: 在jinja2模板中,您应该修改代码以指定:
<form method=post enctype=multipart/form-data action={{ url_for('file_uploader')}}>
<span class="btn btn-primary btn-file"> Browse
<input type=file name=file>
</span>
<input type=submit class="btn btn-success" value=Upload>
</form>
