Question

I m试图搭建一个单页薄片,使用户能够下载一个字页文件。我已经指出,如何使用假思-思想制作/回避文件,但现在我需要在答复中提供该文件。任何想法?

这里我迄今为止所做的事情:

from flask import Flask, render_template
from docx import Document
from cStringIO import StringIO

@app.route( / )
def index():
    document = Document()
    document.add_heading("Sample Press Release", 0)
    f = StringIO()
    document.save(f)
    length = f.tell()
    f.seek(0)
    return render_template( index.html )

Answer 1

页: 1

from flask import Flask, render_template, send_file
from docx import Document
from cStringIO import StringIO

@app.route( / )
def index():
    document = Document()
    document.add_heading("Sample Press Release", 0)
    f = StringIO()
    document.save(f)
    length = f.tell()
    f.seek(0)
    return send_file(f, as_attachment=True, attachment_filename= report.doc )

Answer 2

www.un.org/spanish/ecosoc 转过我的人:

提及这两个联系:

python 3.x ImportError: No module named cStringIO [StackOverFlow Question]
TypeError: string argument expected, got bytes [GitHub issue]

io.StringIO 现在改为<代码>cStringIO。

also it will raise an error as document.save(f) should receive a path or binary file

<>strong>code should be such:

from flask import Flask, render_template, send_file
from docx import Document
from io import BytesIO

@app.route( / )
def index():
    document = Document()
    f = BytesIO()
    # do staff with document
    document.save(f)
    f.seek(0)

    return send_file(
        f,
        as_attachment=True,
        # Use attachment_name for Flask version < 2.2.0
        download_name= report.docx 
    )

Answer 3

可在上使用<代码>send_from_directory 。答案。

如果你寄出案文,你也可以使用<代码>make_response。参看 https://stackoverflow.com/a/23354496/3586654>。答案。

Answer 4

用途

return Response(generate(), mimetype= text/docx )

Generate() should be replaced with f in your case For more information look at streaming in flask http://flask.pocoo.org/docs/1.0/patterns/streaming/
