	Buffer-Oriented Parsing	面向缓冲区的解析
	A subclass of __basic_parser__ can be invoked directly, without using the provided stream operations. This could be useful for implementing algorithms on objects whose interface does not conform to __Stream__. For example, a [@http://zeromq.org/ ZeroMQ socket]. The basic parser interface is interactive; the caller invokes the function [link beast.ref.boost__beast__http__basic_parser.put `basic_parser::put`] repeatedly with buffers until an error occurs or the parsing is done. The function [link beast.ref.boost__beast__http__basic_parser.put_eof `basic_parser::put_eof`] Is used when the caller knows that there will never be more data (for example, if the underlying connection is closed),	__basic_parser__ 的子类可以直接调用，无需使用库提供的流操作。这对于在接口不符合 __Stream__ 要求的对象（例如 [@http://zeromq.org/ ZeroMQ 套接字]）上实现算法时非常有用。基本解析器接口是交互式的：调用方反复调用 [link beast.ref.boost__beast__http__basic_parser.put `basic_parser::put`] 函数并传入缓冲区，直到发生错误或解析完成。当调用方确认不会再有更多数据时（例如底层连接已关闭），可使用 [link beast.ref.boost__beast__http__basic_parser.put_eof `basic_parser::put_eof`] 函数。
26	Parser Options	解析器选项
	The parser provides a few options which may be set before parsing begins:	解析器提供若干选项，这些选项可在解析开始前进行设置：
30	Parser Options	解析器选项
	Name	名称
	Default	默认值
	Description	描述
	[link beast.ref.boost__beast__http__basic_parser.eager.overload2 `eager`]	[link beast.ref.boost__beast__http__basic_parser.eager.overload2 `eager`]
30	`false`
	Normally the parser returns after successfully parsing a structured element (header, chunk header, or chunk body) even if there are octets remaining in the input. This is necessary when attempting to parse the header first, or when the caller wants to inspect information which may be invalidated by subsequent parsing, such as a chunk extension. The `eager` option controls whether the parser keeps going after parsing structured element if there are octets remaining in the buffer and no error occurs. This option is automatically set or cleared during certain stream operations to improve performance with no change in functionality.	在通常处理流程中，即便输入数据中仍存在未解析的八位字节，解析器在成功解析一个结构化元素（如头部、分块头部或分块体）后也会立即返回。此行为在需要先解析头部，或调用方希望在后续解析可能覆盖某些信息（例如分块扩展）之前进行检查的场景下非常关键。`eager` 选项用于控制解析器在成功解析结构化元素后，若缓冲区中仍存在剩余字节且未发生错误，是否继续执行解析。该选项会在特定流操作中被自动启用或禁用，以便在不影响功能的前提下优化性能。
	[link beast.ref.boost__beast__http__basic_parser.skip.overload2 `skip`]	[link beast.ref.boost__beast__http__basic_parser.skip.overload2 `skip`]
	This option controls whether or not the parser expects to see an HTTP body, regardless of the presence or absence of certain fields such as Content-Length or a chunked Transfer-Encoding. Depending on the request, some responses do not carry a body. For example, a 200 response to a [@https://tools.ietf.org/html/rfc7231#section-4.3.6 CONNECT] request from a tunneling proxy, or a response to a [@https://tools.ietf.org/html/rfc7231#section-4.3.2 HEAD] request. In these cases, callers may use this function inform the parser that no body is expected. The parser will consider the message complete after the header has been received.	该选项用于控制解析器是否期待接收 HTTP 消息体，这个判断独立于 Content-Length 或分块传输编码等字段是否存在。某些类型的响应本身就不包含消息体。例如，隧道代理对 CONNECT 请求返回的 200 响应，或者对 HEAD 请求的响应。在这些场景下，调用方可以使用该函数告知解析器不需要消息体。解析器在收到头部后就会将消息视为已完整接收。
	[link beast.ref.boost__beast__http__basic_parser.body_limit `body_limit`]	[link beast.ref.boost__beast__http__basic_parser.body_limit `body_limit`]
	1MB/8MB	1MB/8MB
	This function sets the maximum allowed size of the content body. When a body larger than the specified size is detected, an error is generated and parsing terminates. This setting helps protect servers from resource exhaustion attacks. The default limit when parsing requests is 1MB, and for parsing responses 8MB.	该函数用于设置消息体允许的最大大小。一旦检测到消息体超过该限制，就会触发错误并终止解析过程。这项设置有助于防范资源耗尽攻击，提升服务器安全性。解析请求时的默认限制为 1MB，解析响应时的默认限制为 8MB。
	[link beast.ref.boost__beast__http__basic_parser.header_limit `header_limit`]	[link beast.ref.boost__beast__http__basic_parser.header_limit `header_limit`]
	8KB	8KB
	This function sets the maximum allowed size of the header including all field name, value, and delimiter characters and also including the CRLF sequences in the serialized input.	该函数用于设置头部允许的最大大小，该大小包括所有字段名、字段值、分隔符字符以及序列化输入中的 CRLF 序列。
	Read From std::istream __example__	从 std::istream 读取 __示例__
	The standard library provides the type `std::istream` for performing high level read operations on character streams. The variable `std::cin` is based on this input stream. This example uses the buffer oriented interface of __basic_parser__ to build a stream operation which parses an HTTP message from a `std::istream`:	标准库提供 `std::istream` 类型，用于在字符流上执行高层读取操作。`std::cin` 变量就是基于该输入流实现的。本示例借助 __basic_parser__ 的面向缓冲区接口，构建一个流操作，用于从 `std::istream` 中解析 HTTP 消息：
	Parsing from a `std::istream` could be implemented using an alternate	从 `std::istream` 解析数据，该操作还可以通过另一种方式实现：
