node.js - Is there any way to have Express draw from two file system directories for one web directory? -

-

Say that I want a clear directory, via http: // which / images / / Code>

But on the file system, it is actually both / users / me / www / images and / users / me / moreimages / . So if I request the http: //whatever/images/selfie.jpg , then it first searches for / user / iMA / www / images / selfie.jpeg , And if not found, serve / user / me / more / live / JPEG instead.

I can think of some of the ugly ways of doing this, but I want to do it in "right" and hopefully straightforward way. Does the expression have some work, where I can do it to do this?

Yes, this is possible. Just mounted on the / images in two instances: 

  router.use ('/ images', express.static ('/ users / me / images /') ); Router. ('/ Images', express.static (' / user / mine / more images' '));

If the request in the first instance of the middleware is not satisfied, the second will be processed, and so on.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
