Flask生成下载文件 – 烛影摇红 – 51CTO技术博客
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)
“
{% 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 }}&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：
