我正在嘗試一些應該很簡單的事情。我想從Mongo中返回一個返回的JSON值,並驗證這個值是我期待的。爲此,我使用json_object_to_json_string返回json輸出的字符串值。json_object_to_json_string在'c'中返回值WITHOUT引號
問題是字符串正在用雙引號圍繞該值返回:返回EX「562416504bacd3940b8b2d5c」而不是562416504bacd3940b8b2d5c。
然後這阻止我能夠做一個簡單的匹配(見下文)。
反正有沒有惱人的雙引號得到json值?
struct json_object *new_obj;
// Fetch document
while (mongoc_cursor_next (cursor, &doc))
{
char *docAsJSON = bson_as_json (doc, NULL);
// Grab account_id from session table
new_obj = json_tokener_parse(docAsJSON);
new_obj = json_object_object_get(new_obj, "account_id");
char * account_id_fromSession = json_object_to_json_string(new_obj);
if (strcmp(account_id,account_id_fromSession) == 0)
{
printf("\nids are the same\n\n");
}
else
{
printf("\nids are NOT the same %s %s\n\n",account_id,account_id_fromSession);
}
輸出的代碼:
ids are NOT the same 562416504bacd3940b8b2d5c "562416504bacd3940b8b2d5c"
