烧瓶，Python：文件没有保存在文件夹“images”

-1

我想创建名为“images”的新文件夹，并在“images”文件夹中保存文件[来自upload.html]。我的问题是，文件夹正在生成，但文件没有保存到文件夹中。请参阅下面附带的代码。烧瓶，Python：文件没有保存在文件夹“images”

upload.html 

<!DOCTYPE html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Convert csv to JSON</title> 
</head> 
<body> 
<form action="{{url_for('upload')}}" method="post" enctype="multipart/form-data"> 
<input type="file" name="upload" accept="image/"/> 
<input type="submit" /></form> 

</body> 
</html>

控制台出套上

是：

E:/images 
<FileStorage: u'I-94.pdf' ('application/pdf')> 
('Accept incoming file:', u'I-94.pdf') 
E:/images/I-94.pdf 

    File "E:\datamining\tryproject\convert.py", line 32, in upload 
    upload.save(destination) 
AttributeError: 'function' object has no attribute 'save'

Python代码如下所示

convert.py 

import os 

from flask import Flask, request, render_template, send_from_directory 

__author__ = 'praveen' 

app = Flask(__name__) 

APP_ROOT = os.path.dirname(os.path.abspath(__file__)) 


@app.route("/") 
def index(): 
    return render_template("upload.html") 


@app.route("/upload", methods=["POST"]) 
def upload(): 

    target = os.path.join(APP_ROOT, '/images') 
    print(target) 
    if not os.path.isdir(target): 
     os.mkdir(target) 

    for file in request.files.getlist("upload"): 
     print(file) 

     filename = file.filename 
     destination = "/".join([target, filename]) 
     print("Accept incoming file:", filename) 
     print(destination) 
     upload.save(destination) 

if __name__ == "__main__": 
    app.run(port=4555, debug=True)

'upload'是您的视图函数的名称，而不是文件对象。 – stamaimer

@stamaimer谢谢你的建议。现在工作正常。 – praveen

@eyllanesc我做了更正并发布了正确答案。 – praveen

convert.py 

import os 

from flask import Flask, request, render_template, send_from_directory 

__author__ = 'praveen' 

app = Flask(__name__) 

APP_ROOT = os.path.dirname(os.path.abspath(__file__)) 


@app.route("/") 
def index(): 
    return render_template("upload.html") 


@app.route("/upload", methods=["POST"]) 
def upload(): 

    target = os.path.join(APP_ROOT, '/images') 
    print(target) 
    if not os.path.isdir(target): 
     os.mkdir(target) 

    for file in request.files.getlist("upload"): 
     print(file) 

     filename = file.filename 
     destination = "/".join([target, filename]) 
     print("Accept incoming file:", filename) 
     print(destination) 
     file.save(destination) //i made change here 

if __name__ == "__main__": 
    app.run(port=4555, debug=True)

从这个删除斜线：

target = os.path.join(APP_ROOT, '/images')

所以它会是：

target = os.path.join(APP_ROOT, 'images')
