django项目中使用nginx+fastdfs上传图片和使用图片的流程

django项目中使用nginx+fastdfs上传图片和使用图片的流程

自定义文件存储类

1.先弄清楚django中默认的上传文件存储FileSystemStorage类类过程

1.在utils/fdfs/创建一个storage.py文件2.编写内容

# 自定义文件存储类from django.core.files.storage import Storagefrom fdfs_client.client import Fdfs_clientclass FDFSStorage(Storage): def __init__(self, client_conf=None, base_url=None): """初始化传参""" if client_conf is None: client_conf = './utils/fdfs/client.conf' self.client_conf = client_conf if base_url is None: base_url = ' self.base_url = base_url """fast dfs文件存储类""" def _open(self, name, mode='rb'): """打开文件时 使用""" pass def _save(self, name, content): """ 保存文件时使用 :param name: 你选择的上传文件名字 :param content: 包含你上传文件内容的File对象 :return: 返回字典格式 """ # 创建一个fdfs_client对象 client = Fdfs_client(self.client_conf) # 上传文件到fast dfs系统中 res = client.upload_by_buffer(content.read()) """ { 'Group name' : group_name, 'Remote file_id' : remote_file_id, 'Status' : 'Upload successed.', 'Local file name' : '', 'Uploaded size' : upload_size, 'Storage IP' : storage_ip } """ if res.get('Status') != 'Upload successed.': # 上传失败 raise Exception('上传文件到fastdfs失败') # 获取返回的文件ID file_name = res.get('Remote file_id') return file_name def exists(self, name): """django判断文件名是否可用 因为django这边无法判断文件名，所以我们直接返回False """ return False def url(self, name): """返回访问文件url路径""" return self.base_url + name

3.将client.conf文件存放到utils/fdfs/目录下并修改内容

# connect timeout in seconds# default value is 30sconnect_timeout=30# network timeout in seconds# default value is 30snetwork_timeout=60# the base path to store log filesbase_path=/Users/mac/Desktop #修改为你本地mac上可以存放日志的路径# tracker_server can ocur more than once, and tracker_server format is# "host:port", host can be hostname or ip addresstracker_server=172.16.176.3:22122 #修改为你ubuntu虚拟机中ip地址#standard log level as syslog, case insensitive, value list:### emerg for emergency### alert### crit for critical### error### warn for warning### notice### info### debuglog_level=info# if use connection pool# default value is false# since V4.05use_connection_pool = false# connections whose the idle time exceeds this time will be closed# unit: second# default value is 3600# since V4.05connection_pool_max_idle_time = 3600# if load FastDFS parameters from tracker server# since V4.05# default value is falseload_fdfs_parameters_from_tracker=false# if use storage ID instead of IP address# same as tracker.conf# valid only when load_fdfs_parameters_from_tracker is false# default value is false# since V4.05use_storage_id = false# specify storage ids filename, can use relative or absolute path# same as tracker.conf# valid only when load_fdfs_parameters_from_tracker is false# since V4.05storage_ids_filename = storage_ids.conf#HTTP settings"#include" directive to include HTTP other settiongs##include 文件 存储类

# 指定使用我们自定义的上传文件存储类DEFAULT_FILE_STORAGE='utils.fdfs.storage.FDFSStorage'

使用admin后台管理 测试一下

# 1.找到有图片上传的模型类，然后在admin注册下from django.contrib import adminfrom .models import GoodsTypeadmin.site.register(GoodsType)# 2.创建超级 用户 python manage.py cratesuperuser# 3.上传中出现的问题解决方法 #报错No module named mutagenpip install mutagen#报错 No module named 'mutagen._compat'进入到/Users/mac/.virtualenvs/django_2.2/lib/python3.8/site-packages/fdfs_client/utils.py修改导包路径 from mutagen._senf._compat import StringIO# 报错报错 No module named requestspip install requests# 4.成功上传后的显示内容 如下图
