The container offers value semantics including move and copy if supported by __Body__ and __Fields__. User defined template function parameters can accept any message, or can use partial specialization to accept just requests or responses. The default __fields__ is a provided associative container using the standard allocator and supporting modification and inspection of fields. As per __rfc7230__, a non-case-sensitive comparison is used for field names. User defined types for fields are possible. The `Body` type determines the type of the container used to represent the body as well as the algorithms for transferring buffers to and from the container. The library comes with a collection of common body types. As with fields, user defined body types are possible.
该容器提供值语义，支持移动和拷贝操作（前提是 __Body__ 和 __Fields__ 支持这些操作）。用户定义的模板函数参数可以接受任意消息，也可通过偏特化仅接受请求或响应。默认的 __fields__ 是一个关联容器，使用标准分配器，支持字段的修改与查询。根据 __rfc7230__，字段名称比较时不区分大小写。用户也可以自定义字段类型。`Body` 类型决定消息体的容器类型，以及用于在容器与缓冲区之间传输数据的算法。该库提供一组常用的消息体类型。与字段类似，用户也可以自定义消息体类型。
Sometimes it is desired to only work with a header. Beast provides a single class template __header__ and some aliases to model HTTP/1 and HTTP/2 headers:
有时只需处理头部信息。Beast 提供单个类模板 __header__ 及若干别名，用于表示 HTTP/1 和 HTTP/2 头部：

using response_header = header<false, Fields>;
Requests and responses share the version, fields, and body but have a few members unique to the type. This is implemented by declaring the header classes as partial specializations of `isRequest`. __message__ is derived from __header__; a message may be passed as an argument to a function taking a suitably typed header as a parameter. Additionally, `header` is publicly derived from `Fields`; a message inherits all the member functions of `Fields`. This diagram shows the inheritance relationship between header and message, along with some of the notable differences in members in each partial specialization:
请求和响应共享版本号、字段及消息体，但各自拥有一些特有的成员。该设计通过将 `header` 类声明为 `isRequest` 的偏特化来实现。__message__ 派生自 __header__，因此消息可作为参数传递给接受相应类型头部参数的函数。此外，`header` 公开继承自 `Fields`，因此消息也继承了 `Fields` 的所有成员函数。下图展示 `header` 与 `message` 的继承关系，以及每个偏特化中部分显著成员的差异：

This body is represented by a file opened for either reading or writing. Messages with this body may be serialized and parsed. HTTP algorithms will use the open file for reading and writing, for streaming and incremental sends and receives.
该消息体类型通过一个已打开的文件来表示，可用于读取或写入。带有该消息体类型的消息支持序列化和解析操作。HTTP 算法会利用这个已打开的文件执行读写操作，从而支持流式传输及增量式数据收发。

In this code we create an HTTP response with a status code indicating success. This message has a body with a non-zero length. The function [link beast.ref.boost__beast__http__message.prepare_payload `message::prepare_payload`] automatically sets the Content-Length or Transfer-Encoding field depending on the content and type of the `body` member. Use of this function is optional; these fields may also be set explicitly.
以下代码创建一个带有成功状态码的 HTTP 响应。该消息包含一个非空的消息体。prepare_payload 函数会根据 body 成员的内容和类型自动设置 Content-Length 或 Transfer-Encoding 字段。该函数可调用也可不调用；这些字段也可手动显式设置。
