Question

我跟着这个tutorial但是无法将文件上传到我想要的目录。它说这是成功的，但文件不在它应该的目录中。

更新我更改了我的views.py以尝试修复目录调用，但现在我收到此错误：

File "/home/jsnyder10/Documents/45/app/views.py", line 33, in uploader
 f.save(os.path.join(app.config['UPLOAD_FOLDER']),secure_filename(f.filename))
IOError: [Errno 21] Is a directory: '/home/jsnyder10/Documents/45/uploads'

views.py

@app.route('/mobility_import_html')
@login_required
def mobility_import_html():
   return render_template('mobility_import_html.html')


@app.route('/uploader', methods = ['GET', 'POST'])
def uploader():
   if request.method == 'POST':
      f = request.files['file']
      #f.save(secure_filename(f.filename))
      f.save(os.path.join(app.config['UPLOAD_FOLDER']),secure_filename(f.filename))
      print("f.filename", f.filename)
      return 'success'

mobility_import_html.html

{% extends "mobility.html" %}

{% block mobility %}
      <form action ="{{ url_for('uploader') }}" method = "POST" 
         enctype = "multipart/form-data">
         <input type = "file" name = "file" />
         <input type = "submit"/>
      </form>
{% endblock %}

初始化的.py

import os
from flask import Flask
from flask.json import JSONEncoder
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager
from flask_mail import Mail
from flask_babel import Babel, lazy_gettext
from config import basedir, ADMINS, MAIL_SERVER, MAIL_PORT, MAIL_USERNAME, \
MAIL_PASSWORD
from .momentjs import momentjs

app.config["UPLOAD_FOLDER"] = os.path.join(basedir, 'uploads')

您的保存行应该是：

public class ShopFragment extends Fragment {
    FragmentManager fm;
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        View rootview= inflater.inflate(R.layout.i_fragment_shop,container,false);
        String[] list1={"Chemicals","Pigments","Uniforms","Safety Products"};
        ListView listView= (ListView) rootview.findViewById(R.id.mainlist);
        ArrayAdapter<String> listviewadapter=new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,list1);
        listView.setAdapter(listviewadapter);
          fm =getFragmentManager();
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                if(position==0){
                   fm.beginTransaction().replace(R.id.content_frame,new Chemical_Fragment()).addToBackStack("shop").commit();
                }
                if(position==1){
                fm.beginTransaction().replace(R.id.content_frame,new Pigments_Fragment()).addToBackStack("shop").commit();
                }
                if(position==2){
                 fm.beginTransaction().replace(R.id.content_frame,new Uniforms_Fragment()).addToBackStack("shop").commit();
                    }
                if(position==3){
                 fm.beginTransaction().replace(R.id.content_frame,new SafetyProducts_Fragment()).addToBackStack("shop").commit();
                }
            }
        });
        return rootview;
    }
}
