3 前端项目规范

3.1 文件夹命名

• 全局通用的组件放在 src/components 下
• 其他业务页面中的组件，放在各自页面下的 ./components 文件夹下
• 普通文件夹建议使用 kebab-case 方式命名
• 属于 components 文件夹下的子文件夹，使用大写字母开头的 PascalBase风格

3.2 文件命名规范

3.2.1 .js 问价命名规范

.js 文件，使用 kebab-case 风格
属于Api的，统一加上Api后缀

3.2.2 .vue 文件命名规范

除index.vue之外， 其他 .vue 文件统一用 PascalBase 风格

3.3 函数命名规范

3.3.1 后端配置路由规范

// 书籍管理接口
export const getBookList = (params, headers) => axios_get('/book/books/', params, headers)
export const addBook = (params, headers) => axios_get('/book/books/', params, headers)
export const updateBook = (params, headers) => axios_get('/book/books/', params, headers)
export const delBook = (params, headers) => axios_get('/book/books/', params, headers)

3.3.2 函数命名规范

handleLogin(){
    
}
getOtherQuery(query){
    
}

4 反射

• hasattr(ogj,name_str)判断一个对象里是否有对应的字符串方法
• getattr(obj,name_str)根据字符串去获取obj对象里的对应的方法的内存地址
• 使用stattr给类实例对象动态添加一个新的方法
• delattr删除实例属性

class Dog(object):
    def eat(self, food):
        print('eat method!!!', food)
d = Dog()

# hasatrr 判断对象d是否有eat方法，有返回True，没有返回False
print(hasattr(d, 'eat'))        # True
print(hasattr(d, 'play'))       # False

if hasattr(d, 'eat'):
    func = getattr(d, 'eat')
    func('baba')
    
# True
# False
# eat method!!! baba
