This installs async-exit-stack and async-generator. 这会安装 async-exit-stack 和 async-generator。 You can also use the alternative method with a “middleware” explained at the end. 您还可以将替代方法与最后说明的『中间件』一起使用。 Now use the SessionLocal class we created in the sql_ap...
alias_generator: 生成别名的函数,用于字段名称,通常用于生成符合特定API规范的别名。 allow_population_by_field_name: 允许通过字段名称而不是别名来填充模型数据。 min_anystr_length: 字符串和字节类型字段的最小长度。 max_anystr_length: 字符串和字节类型字段的最大长度。
async def create_product(request: Request, id_generator: IdGenerator = Depends(get_id_generator)): 我有一个依赖关系文件。 def get_id_generator() -> IdGenerator: return UUIDIdGenerator() 我也有SomeOtherIdGenerator我想用来测试。我就是做不好。
