依赖的软件:
autoconf
automake
check
pcre
jemalloc
graphviz version 2.38.0 (20140413.2041)
规则写法:
/blog/post/{id} use [^/]+ regular expression by default.
/blog/post/{id:d+} use `d+` regular expression instead of default.
编程示例:
#include
// create a router tree with 10 children capacity (this capacity can grow dynamically)
n = r3_tree_create(10);
int route_data = 3;
// insert the route path into the router tree
r3_tree_insert_pathl(n , "/zoo" , strlen("/zoo") , NULL, &route_data );
r3_tree_insert_pathl(n , "/foo/bar" , strlen("/foo/bar") , NULL, &route_data );
r3_tree_insert_pathl(n , "/bar" , strlen("/bar") , NULL, &route_data );
r3_tree_insert_pathl(n , "/post/{id}" , strlen("/post/{id}") , NULL, &route_data );
r3_tree_insert_pathl(n , "/user/{id:\d+}" , strlen("/user/{id:\d+}") , NULL, &route_data );
// let's compile the tree!
r3_tree_compile(n);
// dump the compiled tree
r3_tree_dump(n, 0);
// match a route
node *matched_node = r3_tree_match(n, "/foo/bar", strlen("/foo/bar"), NULL);
matched_node->endpoint; // make sure there is a route end at here.
int ret = *( (*int) matched_node->route_ptr );
