根据 `position` 与参数类型(是否标量)生成绑定器调用:
|
- query:标量用 `QueryParam[T]("key")`,非标量用 `Query[T]("key")`
|
||||||
|
- path:标量用 `PathParam[T]("key")`,非标量用 `Path[T]("key")`
|
||||||
- query
|
- 若使用 `model()`(仅在 path 有效),会按字段值查询并绑定为 `T`,详见下文
|
||||||
- 标量类型:`QueryParam[T]("key")`
|
|
||||||
- 非标量类型:`Query[T]("key")`
|
|
||||||
- path
|
|
||||||
- 标量类型:`PathParam[T]("key")`
|
|
||||||
- 非标量类型:`Path[T]("key")`
|
|
||||||
- 若声明了 `model()` 且 position 为 `path`:生成 `PathModel[T]("field", "key")`,表示根据路径参数值按 `field` 查询并绑定为 `T` 实例(`T` 来自方法参数类型)。

|
||||||
- header:`Header[T]("key")`
|
- header:`Header[T]("key")`
|
||||||
- body:`Body[T]("key")`
|
- body:`Body[T]("key")`
|
||||||
- cookie
|
- cookie:`string` 用 `CookieParam("key")`,其他用 `Cookie[T]("key")`
|
||||||
- `string`:`CookieParam("key")`
|
|
||||||
- 其他:`Cookie[T]("key")`
|
|
||||||
- file:`File[multipart.FileHeader]("key")`
|
- file:`File[multipart.FileHeader]("key")`
|
||||||
- local:`Local[T]("key")`
|
- local:`Local[T]("key")`

- 标量类型集合(影响是否使用 `Param` 后缀):`string`、`int`、`int32`、`int64`、`float32`、`float64`、`bool`。

- `key` 默认与 `paramName` 相同;若设置 `key(...)` 则使用其值。
|
- `key` 默认等于 `paramName`;设置 `key(...)` 后以其为准

- 先收集注释中的多条 `@Bind`,再按“方法参数列表顺序”匹配并输出绑定器,确保调用顺序与方法签名一致。

### 示例

### 模型绑定(path + model)
|
||||||
|
|
||||||
|
当 `@Bind ... model(...)` 配合 `position=path` 使用时,将根据路径参数值查询模型并绑定为方法参数类型的实例(`T` 来自方法参数)。
|
||||||
|
|
||||||
|
- 语法:
|
||||||
|
- 仅字段:`model(id)`(推荐)
|
||||||
|
- 指定字段与类型:`model(id:int)`、`model(code:string)`(用于非字符串路径参数)
|
||||||
|
- 指定类型与字段:`model(pkg.Type:field)` 或 `model(pkg.Type)`(字段缺省为 `id`)
|
||||||
|
- 行为:
|
||||||
|
- 生成的绑定器会按给定字段构造查询条件并返回首条记录
|
||||||
|
- 自动注入 import:`field "go.ipao.vip/gen/field"`,用于构造字段条件表达式
|
||||||
|
|
||||||
|
示例:
|
||||||
|
|
||||||
|
```go
|
||||||
|
// @Router /users/:id [get]
|
||||||
|
// @Bind user path key(id) model(id)
|
||||||
|
func (uc *UserController) Show(ctx context.Context, user *models.User) (*UserDTO, error)
|
