Hi Francis,
thank you for your input!
I have requirement to create own cookie based on input and wirte the that
cookie in header.
whenever i need that i can read from header and use it.
for example:-
I have created my own cookie "thissomevalue" worte in header and later the
same read from header.
Please check my code and let me know why i am not able to read the value
from header.
Below code snippet to set header value in request header:-
ngx_table_elt_t *cookie;
cookie = ngx_list_push(&r->headers_in.headers);
cookie->lowcase_key = (u_char*) "cookie";
ngx_str_set(&cookie->key, "Cookie");
ngx_str_set(&cookie->value, "somevalue");
cookie->hash = ngx_crc32_long(cookie->lowcase_key, cookie->key.len);
Below code snippet to read set value from header:-
ngx_http_core_main_conf_t *clcf;
ngx_str_t *type;
ngx_uint_t key;
ngx_str_t val = ngx_string("cookie");
clcf = ngx_http_get_module_main_conf(r, ngx_http_core_module);
key= ngx_hash_key_lc(val.data, val.len);
type = ngx_hash_find(&clcf->headers_in_hash, key, val.data, val.len);
if (type != NULL)
{
ngx_table_elt_t *test_val;
test_val= ngx_list_push(&r->headers_out.headers);
test_val->lowcase_key = (u_char*) "test_val";
ngx_str_set(&test_val->key, "Test_Val");
ngx_str_set(&test_val->value, type->data);
test_val->hash = ngx_crc32_long(test_val->lowcase_key, test_val->key.len);
}
curl response:-Test_val was accepting "somevalue"
