HTTP/1.1标头的新行定义 [英] New Line definition for HTTP/1.1 headers

问题描述

我有一个发出HTTP POST请求的嵌入式系统，但是我知道标题必须具有格式.

I have an embedded system that makes a HTTP POST request, however I know that the headers must have a format.

在这种情况下，我有以下要求:

In this case I have this request:

POST / HTTP/1.1\n
Host: 192.168.1.15\n
Connection: close\n
Content-Length: 44\n
Content-Type: application/json\n
\n
{\n
"command": "snapPicture",\n
"selfTimer": 0\n
}

我希望在发送此请求时避免发生任何错误.

I want to avoid any kind of error while I send this request.

1. 严格来说，使用 \n 来告诉new line是正确的还是应该是 \r\n ?

1. Strictly talking, is it correct use \n to tell new line or should be \r\n?

关于此请求格式的任何建议吗?

Any suggestion about this request format?

感谢您的帮助.

推荐答案

您必须使用\r\n分隔标题，并将正文与标题部分分隔开.请参阅 RFC 7230(超文本传输​​协议(HTTP/1.1):消息语法和路由)，第3节.邮件格式:

You must use \r\n to separate headers, also to separate the body from the header section. See RFC 7230 (Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing), section 3. Message Format:

HTTP-message   = start-line
                  *( header-field CRLF )
                  CRLF
                  [ message-body ]

CRLF是\r\n.

其余请求是否有效(尤其是正文)取决于您将请求发送到的服务器.

Whether the rest of the request is valid, especially the body, depends on the server you send it to.
