H3 是一个 C 语言实现的快速的 HTTP Header 解析库。H3使用预先建立的最小完美哈希表来定义header字段名称，以提供快速的字段名称查找。
示例代码：
h3_request_header_parse(RequestHeader *header, const char *header, int len); /* * Request Header * http://tools.ietf.org/html/rfc2616#section-5.3 */ Value * h3_get_accept(HeaderFields *headers); // Get "Accept" Value * h3_get_accept_charset(HeaderFields *headers); // Get "Accept-Charset" Value * h3_get_accept_language(HeaderFields *headers); // Get "Accept-Language" Value * h3_get_accept_encoding(HeaderFields *headers); // Get "Accept-Encoding" Value * h3_get_authorization(HeaderFields *headers); // Get "Authorization" Value * h3_get_expect(HeaderFields *headers); // Get "Expect" Value * h3_get_from(HeaderFields *headers); // Get "From" Value * h3_get_host(HeaderFields *headers); // Get "Host" Value * h3_get_if_match(HeaderFields *headers); // Get "If-Match" Value * h3_get_if_none_match(HeaderFields *headers); // Get "If-None-Match" Value * h3_get_if_range(HeaderFields *headers); // Get "If-Range" Value * h3_get_if_unmodified_since(HeaderFields *headers); // Get "If-Unmodified-Since" Value * h3_get_range(HeaderFields *headers); // Get "Range" Value * h3_get_referer(HeaderFields *headers); // Get "Referer" Value * h3_get_max_forwards(HeaderFields *headers); // Get "Max-Forwards" Value * h3_get_proxy_authorization(HeaderFields *headers); // Get "Proxy-Authorization" Value * h3_get_range(HeaderFields *headers); // Get "Range" Value * h3_get_user_agent(HeaderFields *headers); // Get "User-Agent" Value * h3_get_te(HeaderFields *headers); // Get "TE" /* * Response Header * http://tools.ietf.org/html/rfc2616#section-6 */ Value * h3_get_accept_encoding(HeaderFields *headers); // Get "Accept-Encoding" Value * h3_get_accept_language(HeaderFields *headers); // Get "Accept-Language" Value * h3_get_accept_ranges(HeaderFields *headers); // Get "Accept-Ranges" Value * h3_get_cache_control(HeaderFields *headers); // Get "Cache-Control" Value * h3_get_connection(HeaderFields *headers); // Get "Connection" Value * h3_get_date(HeaderFields *headers); // Get "Date" Value * h3_get_transfer_encoding(HeaderFields *headers); // Get "Transfer-Encoding" Value * h3_get_upgrade(HeaderFields *headers); // Get "Upgrade" Value * h3_get_via(HeaderFields *headers); // Get "Via" Value * h3_get_warning(HeaderFields *headers); // Get "Warning"
#include <h3.h> int main() { RequestHeader *header; header = h3_request_header_new(); h3_request_header_parse(header, headerBody, len); printf("HEADER\n"); printf("===========================\n"); printf("%s", headerBody); printf("\n---------------------------\n"); printf("Method: %.*s\n", header->RequestMethodLen, header->RequestMethod); printf("Request-URI: %.*s\n", header->RequestURILen, header->RequestURI); printf("HTTP-Version: %.*s\n", header->HTTPVersionLen, header->HTTPVersion); printf("===========================\n"); h3_request_header_free(header); return 0; }
