>>>>>细分小功能

判断路径

def isPath(path):
return os.path.exists(path)

输如输出流

def StreamDumpLoad(path,rOw,obj=None):
if isPath(path):
tempObj=None
with open(path,rOw) as f:
if rOw==”w”:
json.dump(obj, f)
elif rOw==”r”:
tempObj= json.load(f)
return tempObj

创建默认的文章表 ，【Article/文章表.json】

def C_D_Article(userName,path=”Article”):
if not isPath(path):
os.mkdir(path)
if isPath(path):
tempPath = os.path.join(path, userName + “.json”)
# print(tempPath)
tempObj = {“Article”: [{“title”: “DefaultArticle”,”author”: userName,
“time”: datetime.strftime(datetime.now(), “%Y-%m-%d %H:%M:%S”),
“content”: “DefaultContent”,}]}
with open(tempPath,”w”) as f_w:
json.dump(tempObj,f_w)
# print(“写入成功”)

1>>>>>默认的用户配置表 {“user”：[{“name”:”admin”,”pwd”:”123456”}]}

def C_D_User(path=”user.json”):
# 文件不存在创建
defaultUser={“user”:[{“name”:”admin”,”pwd”:”123456”}]}
if not isPath(path):
with open(path,”w”) as f_w:
json.dump(defaultUser,f_w)
C_D_Article(“admin”)

2>>>>>读取用户表 返回 用户字典

def ReadAllUser(path=”user.json”):
return StreamDumpLoad(path,”r”)

3>>>>>添加用户

def AddUser(name,pwd,path=”user.json”):
#本次的用户
tempUser={“name”:name,”pwd”:pwd}
#读取所有的原来用户字典
tempAllUser=ReadAllUser(path)
#读取用户列表
userLIst=tempAllUser[“user”]
#添加本次用户
userLIst.append(tempUser)
#写入配置表
StreamDumpLoad(path,”w”,tempAllUser)

4>>>>>账号的注册 ，不重复才能注册

def Register(path=”user.json”):
if isPath(path):
userName=input(“请输入用户名？”)
userPwd=input(“请输入密码？”)
if userName!=”” and userPwd!=”“:
#读取所有用户列表
userDict=ReadAllUser(path)
#假定该用户不在
isFind=False
for i in userDict[“user”]:
if i[“name”]==userName:
isFind=True
print(“用户已存在,注册失败”)
break
if isFind==False:
userDict[“user”].append({“name”:userName,”pwd”:userPwd})
StreamDumpLoad(path,”w”,userDict)
print(“注册成功”)
C_D_Article(userName)
else:
print(“账号密码不能为空，注册失败”)

5>>>>>登录功能

def Login(path=”user.json”):
if isPath(path):
userName = input(“请输入用户名？”)
userPwd = input(“请输入密码？”)
if userName != “” and userPwd != “”:
# 读取所有用户列表
userDict = ReadAllUser(path)
# 假定该用户不在
isFind = False
for i in userDict[“user”]:
if i[“name”] == userName and i[“pwd”]==userPwd:
print(“登陆成功”)
global globalUser
globalUser=userName
isFind=True
break
if isFind==False:
print(“登录失败”)
return isFind

2.写文章，包含【标题，作者，时间，内容】

>>>>>细分小功能

1>>>>>>读取所有文章

def ReadAllArticle(userName,path=”Article”):
tempPath=os.path.join(path,userName+”.json”)
return StreamDumpLoad(tempPath,”r”)

2>>>>>>添加文章

def AddArticle(userName,path=”Article”):
title=input(“请输入文章标题？\n>>>>>:”)
content=input(“请输入文章内容？\n>>”)
#当前文章的结构
tempArticle={“title”: title,”author”: userName,”time”: datetime.strftime(datetime.now(),”%Y-%m-%d %H:%M:%S”),
“content”: content,}
#读取所有文章
allArticle=ReadAllArticle(userName)
# 添加当前的文章
allArticle[“Article”].append(tempArticle)
#临时路径
tempPath=os.path.join(path,userName+”.json”)
#写入文章
StreamDumpLoad(tempPath,”w”,allArticle)
print(“文章发表成功”)

3.查询文章，列出所有文章及时间

def SearchAllArticle(userName,path=”Article”):
allDict=ReadAllArticle(userName)
print(“以下为所有文章”)
for i in allDict[“Article”]:
if len(i[“title”])>5:
print(“>>>>”,”标题：”, i[“title”][0:5]+”…”, “\t时间：”, i[“time”])
else:
print(“>>>>”,”标题：”, i[“title”], “\t时间：”, i[“time”])

4.可查看其中一篇文章

def FindOneArticle(userName,path=”Article”):
tempTitle=input(“请输入 要【查找】的文章标题？>>>”)

allArticle=ReadAllArticle(userName,path)

for i in allArticle["Article"]:
    if i["title"].count(tempTitle):
        print("查询到该文章")
        print(">>>>","标题：",i["title"])
        print(">>>>","作者：", i["author"])
        print(">>>>","时间：", i["time"])
        print(">>>>","内容：", i["content"])

5.删除文章

def DeleteArticle(userName,path=”Article”):
tempTitle = input(“请输入 要【删除】 的文章标题？>>>”)

allArticle = ReadAllArticle(userName, path)

for i in range(len(allArticle["Article"])):
    if allArticle["Article"][i]["title"].count(tempTitle):

        del allArticle["Article"][i]
        print("删除成功")
        break
# 临时路径
tempPath = os.path.join(path, userName + ".json")
StreamDumpLoad(tempPath,"w",allArticle)

6.修改文章

def EditArticle(userName,path=”Article”):
tempTitle = input(“请输入 要【修改】 的文章标题？>>>”)

#获得所有文章
allArticle = ReadAllArticle(userName, path)

for i in range(len(allArticle["Article"])):
    if allArticle["Article"][i]["title"].count(tempTitle):
        tempContent = input("请输入 要【修改】 的文章【内容】？>>>")
        allArticle["Article"][i]["content"]=tempContent
        print("修改成功")
        break
# 临时路径
tempPath = os.path.join(path, userName + ".json")
StreamDumpLoad(tempPath, "w", allArticle)

7.退出系统
