The valid characters are defined in RFC 7230 and RFC 3986这个问题怎么解决？

这个问题是关于 HTTP 请求中有效字符的定义。RFC 7230 和 RFC 3986 定义了 HTTP 请求中有效的字符集。

根据 RFC 7230，HTTP 请求中有效的字符包括：

- ASCII 字符集中的可见字符和空格（即 ASCII 32 到 126）
- 水平制表符和换行符

根据 RFC 3986，URI 中有效的字符包括：

- 大小写字母 A 到 Z 和 a 到 z
- 数字 0 到 9
- 符号 "-"、"."、"_"、"~"
- 保留字符（如 "/"、":"、"?"、"#"、"["、"]"、"@"、"!"、"$"、"&"、"'"、"("、")"、"*"、"+"、","、";"、"="）

在 HTTP 请求中，URI 是一个常见的组成部分，因此有效字符集需要同时遵守这两个规范的要求。

如果 HTTP 请求中包含无效字符，服务器可能会返回错误响应。因此，发送 HTTP 请求时需要确保使用有效字符集。

The valid characters are defined in RFC 7230 and RFC 3986

在RFC 7230和RFC 3986中定义了有效字符。RFC 3986规定，URL只允许包含字母，数字以及四个特殊字符（- _ . ~）。这些字符 ! * ’ ( ) ; : @ & = $ , / ? # [ ] 属于保留字符，所以是非法字符，不能出现在URL地址中。 RFC 7230也提到了URL中的有效字符，但没有具体列出字符列表。因此，有效字符的定义可以通过结合这两个RFC来理解。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

The valid characters are defined in RFC 7230 and RFC 3986什么意思

The valid characters in the context of HTTP requests and URIs are defined in two RFC documents: RFC 7230 and RFC 3986.

RFC 7230 defines the syntax and semantics of HTTP/1.1 messages, including the rules for constructing header fields and parsing message components. It specifies the allowed characters in HTTP header field values and the encoding format for non-ASCII characters.

RFC 3986 defines the syntax and semantics of URIs, including the rules for constructing and parsing URIs. It specifies the allowed characters in a URI and the encoding format for reserved characters and non-ASCII characters.

In summary, these two RFC documents define the set of valid characters that can be used in HTTP requests and URIs, and also provide guidelines for handling characters that are not included in this set.
