bson_as_json − bson_as_json()
char * bson_as_json (const bson_t *bson, size_t *length);
• |
bson: A bson_t. |
|||
• |
length: An optional location for the length of the resulting string. |
The bson_as_json() function shall encode bson as a UTF−8 string using libbson's legacy JSON format. This function is superseded by bson_as_canonical_extended_json() and bson_as_relaxed_extended_json(), which use the same MongoDB Extended JSON format as all other MongoDB drivers.
The caller is responsible for freeing the resulting UTF−8 encoded string by calling bson_free() with the result.
If non−NULL, length will be set to the length of the result in bytes.
If successful, a newly allocated UTF−8 encoded string and length is set.
Upon failure, NULL is returned.
#include <bson/bson.h> int main () { bson_t bson; char *str; bson_init (&bson); BSON_APPEND_UTF8 (&bson, "0", "foo"); BSON_APPEND_UTF8 (&bson, "1", "bar"); str = bson_as_json (&bson, NULL); /* Prints * { "0" : "foo", "1" : "bar" } */ printf ("%s\n", str); bson_free (str); bson_destroy (&bson); }
