本文介绍了烧瓶/ Python。从上传的文件获取mimetype的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我使用Flask的micro-framework 0.6和Python 2.6 我需要从上传的文件中获取mimetype,以便存储它。 b $ b 以下是相关的Python / Flask代码: @ app.route('/ upload_file',methods = ['GET','POST']) def upload_file(): if request.method =='POST':$ b $ file = request.files ['file '] mimetype = #FIXME if file: file.save(os.path.join(UPLOAD_FOLDER,'File-Name') return redirect(url_for('uploaded_file ')) else: return redirect(url_for('upload')) 这里是网页的代码: < form action =upload_file 选择要上传的文件:< input type = file name = file> < input type = submit value = Upload> < ; / form> 代码有效,但我需要能够在上传时获取mimetype。我在这里看过Flask文档: http:// flask。 pocoo.org/docs/api/#incoming-request-data 所以我知道它确实得到了mimetype,但是我不知道如何检索它 - 作为一个文本字符串,例如'txt / plain'。 有什么想法? 谢谢。 解决方案从 docs , file.content_type 包含完整的编码类型, mimetype contains只是MIME类型。 @ app.route('/ upload_file',methods = ['GET','POST'] ) def upload_file(): if request.method =='POST': file = request.files.get('file') if file: mimetype = file.content_type filename = werkzeug.secure_filename(file.filename) file.save(os.path.join(UPLOAD_FOLDER,filename) return redirect(url_for('uploaded_file' )) else: return redirect(url_for('upload')) I am using Flask micro-framework 0.6 and Python 2.6I need to get the mimetype from an uploaded file so I can store it.Here is the relevent Python/Flask code:@app.route('/upload_file', methods=['GET', 'POST'])def upload_file(): if request.method == 'POST': file = request.files['file'] mimetype = #FIXME if file: file.save(os.path.join(UPLOAD_FOLDER, 'File-Name') return redirect(url_for('uploaded_file')) else: return redirect(url_for('upload'))And here is the code for the webpage:<form action="upload_file" method=post enctype=multipart/form-data>Select file to upload: <input type=file name=file><input type=submit value=Upload></form>The code works, but I need to be able to get the mimetype when it uploads. I've had a look at the Flask docs here: http://flask.pocoo.org/docs/api/#incoming-request-dataSo I know it does get the mimetype, but I can't work out how to retrieve it - as a text string, e.g. 'txt/plain'.Any ideas?Thank you. 解决方案 From the docs, file.content_type contains the full type with encoding, mimetype contains just the mime [email protected]('/upload_file', methods=['GET', 'POST'])def upload_file(): if request.method == 'POST': file = request.files.get('file') if file: mimetype = file.content_type filename = werkzeug.secure_filename(file.filename) file.save(os.path.join(UPLOAD_FOLDER, filename) return redirect(url_for('uploaded_file')) else: return redirect(url_for('upload')) 这篇关于烧瓶/ Python。从上传的文件获取mimetype的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
