restful architecture - PUT on REST collection. Do I provide addresses? -


when put on rest collection should provide addresses of members in collection?

put on dogs address specified

[{"name":"sparky", "id":1}, {"name":"rusty", "id":2}]

or...

put on dogs without address specified

[{"name":"sparky"}, {"name":"rusty"}]

and let server return locations of new members in collection. in case row ids in table.

if sending put replace every resource in entire collection, should send full new / updated entities.

  • if id part of entity, should send within entity, client has nothing uri (a.k.a "address") of element, clients have knowledge how uri build server.
  • if id not part of entity client, should not send within entity.

but both cases possible , server accept both, important the put on collection behaves in http/1.1 specs described:

the put method requests enclosed entity stored under supplied request-uri.

so if put on /api/animals/dogs/ dogs found under /dogs/ , not e.g. /cats/

if request-uri refers existing resource, enclosed entity should considered modified version of 1 residing on origin server

that means put on collection, delectes whole collection , creates new 1 entities given in body of method call.

if request-uri not point existing resource [...] origin server can create resource uri.

that means if /animals/dogs/ empty should create new collection there.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
