# 表单数据

接收的不是 JSON，而是表单字段时，要使用 `Form`。

!!! info "说明"

    要使用表单，需预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

    例如，`pip install python-multipart`。

## 导入 `Form`

从 `fastapi` 导入 `Form`：

```Python hl_lines="1"
{!../../../docs_src/request_forms/tutorial001.py!}
```

## 定义 `Form` 参数

创建表单（`Form`）参数的方式与 `Body` 和 `Query` 一样：

#define RARG2 R2
#define RARG3 R3
#define FARG R4

// Called from instrumented code.
// func runtime·doasanread(addr unsafe.Pointer, sz, sp, pc uintptr)
TEXT	runtime·doasanread(SB), NOSPLIT, $0-32
	MOVD	addr+0(FP), RARG0
	MOVD	sz+8(FP), RARG1
	MOVD	sp+16(FP), RARG2
	MOVD	pc+24(FP), RARG3
	// void __asan_read_go(void *addr, uintptr_t sz, void *sp, void *pc);
	MOVD	$__asan_read_go(SB), FARG
	JMP	asancall<>(SB)

	_ = x.form // ERROR "x.form undefined (cannot refer to unexported field form)"
	_ = x.forM // ERROR "x.forM undefined (type *big.Float has no field or method forM)"
}

func _() {
	_ = ast.File{Name: nil} // OK
	_ = ast.File{NamE /* ERROR "unknown field NamE in struct literal of type ast.File, but does have Name" */ : nil}

#define RARG2 R6
#define RARG3 R7
#define FARG  R8

// Called from instrumented code.
// func runtime·doasanread(addr unsafe.Pointer, sz, sp, pc uintptr)
TEXT	runtime·doasanread(SB), NOSPLIT, $0-32
	MOVV	addr+0(FP), RARG0
	MOVV	sz+8(FP), RARG1
	MOVV	sp+16(FP), RARG2
	MOVV	pc+24(FP), RARG3
	// void __asan_read_go(void *addr, uintptr_t sz, void *sp, void *pc);
	MOVV	$__asan_read_go(SB), FARG
	JMP	asancall<>(SB)

# 请求表单与文件

FastAPI 支持同时使用 `File` 和 `Form` 定义文件和表单字段。

!!! info "说明"

    接收上传文件或表单数据，要预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

    例如，`pip install python-multipart`。

## 导入 `File` 与 `Form`

```

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

// memory.
func (r *Reader) ReadForm(maxMemory int64) (*Form, error) {
	return r.readForm(maxMemory)
}

var (
	multipartfiles    = godebug.New("#multipartfiles") // TODO: document and remove #

)
