django图片上传到oss_django 配置阿里云OSS存储media文件的例子

1. 安装django-aliyun-oss2-storage包

linux上用 pip install django-aliyun-oss2-storage 无报错,顺利安装

windows上报错:

(python3_sbs) F:\projects\virtualenv\python3_sbs\Scripts>pip install django-aliyun-oss2-storage

Collecting django-aliyun-oss2-storage

Using cached django-aliyun-oss2-storage-0.1.5.tar.gz

Complete output from command python setup.py egg_info:

Traceback (most recent call last):

File "", line 1, in

File "C:\Users\super\AppData\Local\Temp\pip-build-pb4u0qtw\django-aliyun-oss2-storage\setup.py", line 5, in

README = readme.read()

UnicodeDecodeError: 'gbk' codec can't decode byte 0x91 in position 63: illegal multibyte sequence

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in C:\Users\super\AppData\Local\Temp\pip-build-pb4u0qtw\django-aliyun-oss2-storage\

解决方法:

2. 解压进入解压后的文件夹

3. 打开README.md 删除所有内容

4. 安装

python setup.py install

2. 设置setting.py

ACCESS_KEY_ID = "xxxx"

ACCESS_KEY_SECRET = "xxxx"

END_POINT = "oss-cn-"

PREFIX_URL = 'http://'

BUCKET_NAME = "xxx"

ALIYUN_OSS_CNAME = "" # 自定义域名,如果不需要可以不填写

BUCKET_ACL_TYPE = "public-read" # private, public-read, public-read-write

DEFAULT_FILE_STORAGE = 'aliyun_oss2_storage.backends.AliyunMediaStorage'

MEDIA_URL = '/media/'

MEDIA_ROOT = "media"

顺便提一下,当在xadmin后台上传文件, filename的时候,文件会上传到路径

PREFIX_URL + BUCKET_NAME+"."END_POINT+MEDIA_URL+filename

但是在django 模板渲染html的时候,我们取filename是按照格式:

前端html render出来后,其实看到的路径是:

根本取不到阿里云服务器上的文件。所以需要设置个新的变量,如 ALI_MEDIA_URL在模板渲染的时候替换MEDIA_URL.

方法:

1. 创建新文件my_processor.py

from __future__ import unicode_literals

import itertools

from django.conf import settings

from django.middleware.csrf import get_token

from django.utils.encoding import force_text

from django.utils.functional import SimpleLazyObject, lazy

def ali_media(request):

"""

Adds media-related context variables to the context.

"""

return {'ALI_MEDIA_URL': settings.ALI_MEDIA_URL}

2. setting.py中

ALI_MEDIA_URL = PREFIX_URL + BUCKET_NAME + "." + END_POINT + '/media/'

TEMPLATES = [

{

'BACKEND': 'django.template.backends.django.DjangoTemplates',

'DIRS': [os.path.join(BASE_DIR, 'templates')],

'APP_DIRS': True,

'OPTIONS': {

'context_processors': [

'django.template.context_processors.debug',

'django.template.context_processors.request',

'django.contrib.auth.context_processors.auth',

'django.contrib.messages.context_processors.messages',

'django.template.context_processors.media',

'utils.sbs_processor.ali_media',

],

},

},

]

3. 在模板中设置为:

3. 设置uediitor

在DjangoUeditor/view.py中

之前存储到本地的代码是:

# 保存上传的文件

def save_upload_file(PostFile, FilePath):

try:

f = open(FilePath, 'wb')

for chunk in PostFile.chunks():

f.write(chunk)

except Exception as e:

f.close()

return u"写入文件错误:%s" % e

f.close()

return u"SUCCESS"

我们模仿这个写一个上传到阿里云:

#保存上传文件到aliyun

def save_upload_file_to_aliyun(PostFile, Outputfile):

access_key = ACCESS_KEY_ID

secret_key = ACCESS_KEY_SECRET

bucket_name = BUCKET_NAME

try:

import oss2

auth = oss2.Auth(access_key, secret_key)

bucket = oss2.Bucket(auth, END_POINT, bucket_name)

# ret, info = put_file(token, key, upload_file)

result=bucket.put_object(Outputfile, PostFile)

return u"SUCCESS"

# if ret.get('key',None) == None:

# raise Exception('upload error')

# else:

# return u"SUCCESS"

except Exception as e:

print(str(e))

return str(e)

在哪调用呢? 找到:

state = save_upload_file(file, os.path.join(OutputPath, OutputFile))

替换成:

state = save_upload_file_to_aliyun(file, OutputPathFormat)

配置结束。ueditor和xadmin上传的图片都会上传到阿里云oss中
