Flask生成下载文件 – 烛影摇红 – 51CTO技术博客

用flask实现一个上传图片到服务器的功能

Python中使用Flask、MongoDB搭建简易图片服务器 – 新客网

python – flask如何返回图片流? – SegmentFault

实际上此处是想要:

在Flask中,已经得到了一个图片的地址了

现在需要去下载图片到服务器的某个路径上

Flask python download image

Flask python download image to static

python – How to return images in flask response? – Stack Overflow

API — Flask Documentation (0.11)

python – How do you serve a dynamically downloaded image to a browser using flask? – Stack Overflow

python – How do i link to images not in Static folder in flask – Stack Overflow

同时还要去搞清楚:

Flask中,如果下载网络上的图片,保存到服务器中

到底直接保存到static中的某个目录好

还是保存到其它什么地方?比如数据库?

flask save image to server

flask download other site image file to server

Uploading Files — Flask Documentation (0.11)

A flask server for serving all JPEG images in a local directory and subdirectories. Uses unveil.js for lazy-loading of images. Thumbnails are created on the fly by PIL.

    {% for image in images %}
        <a class=”image” href=”{{ image.src }}” style=”width: {{ image.width }}px; height: {{ image.height }}px”>
            <img src=”data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==” data-src=”{{ image.src }}?w={{ image.width }}&amp;h={{ image.height }}” width=”{{ image.width }}” height=”{{ image.height }}” />
        </a>
    {% endfor %}

python – Flask Download a File – Stack Overflow

flask image file storage

[AF]Best way to store avatars, images, etc:flask

flask requests download image

python – Using Flask, how can I download a file from a user-given URL? – Stack Overflow

flask app.open_instance_resource

flask app open folder

API — Flask Documentation (0.11)

->

“static_folder

The absolute path to the configured static folder.”

去试试:

app.static_folder

最后是自己去用:

#download avatar image
avatarUrl = respUserInfoDict[‘headimgurl’]
app.logger.debug(“avatarUrl=%s”, avatarUrl)
avatarReq = requests.get(avatarUrl)
app.logger.debug(“avatarReq=%s”, avatarReq)
staticFolder = app.static_folder
app.logger.debug(“staticFolder=%s”, staticFolder)
avatartName = openid + “.png”
app.logger.debug(“avatartName=%s”, avatartName)
avatarStaticPath = os.path.join(“img/avatar”, avatartName)
app.logger.debug(“avatarStaticPath=%s”, avatarStaticPath)
avatarFullPath = os.path.join(staticFolder, avatarStaticPath)
app.logger.debug(“avatarFullPath=%s”, avatarFullPath)
with open(avatarFullPath, ‘wb’) as f:
    f.write(avatarReq.content)
    f.close()
    app.logger.debug(“downloaded avatar=%s ok”, avatarUrl)

而下载了图片。

对应的log:
