我从烧瓶开始，我的app.py上有这段代码：
from flask import Flask, render_template, request
from flask.ext.uploads import UploadSet, configure_uploads, IMAGES
app = Flask(__name__)
photos = UploadSet('photos', IMAGES)
app.config['UPLOADED_PHOTOS_DEST'] = 'static/img'
configure_uploads(app, photos)
@app.route('/upload', methods=['GET', 'POST'])
def upload():
if request.method == 'POST' and 'photo' in request.files:
filename = photos.save(request.files['photo'])
return filename
return render_template('upload.html')
if __name__ == '__main__':
app.run(debug=True)
我的upload.html代码：
<html>
<head>
<title>Upload</title>
</head>
<body>
<form method=POST enctype=multipart/form-data action="{{ url_for('upload') }}">
<input type=file name=photo>
<input type="submit">
</form>
</body>
</html>
这是文件层次结构：
├── image_upload
│ ├── app
│ │ ├── app.py
│ │ ├── app.pyc
│ │ ├── __init__.py
│ │ ├── __init__.pyc
│ │ ├── routes.py
│ │ ├── routes.pyc
│ │ └── upload.html
│ ├── image_upload.py
│ ├── image_upload.pyc
│ └── static
│ ├── img
│ └── templates
│ └── upload.html
└── install.sh
我的__init__.py文件：
from flask import Flask
app = Flask(__name__)
我的routes.py虽然我没有使用它：
from app import app
@app.route('/')
@app.route('/upload')
def index():
return upload
image_upload.py文件：
from app import app
当我浏览它时总是抛出错误404，它可能是routes.py文件吗？
我对flask更新鲜，所以任何帮助都会受到高度赞赏。
如果我从 init 导入路径文件，它会抛出我：
