Failed to approve

I failed to approve an address to spend my WETH. Can anyone help?

$ curl localhost:8545 -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method":"eth_call", "params":[{"to": "0xc778417e063141139fce010982780140aa0cd5ab", "data": "0x095ea7b3000000000000000000000000e592427a0aece92de3edee1f18e0157c05861564000000000000000000000000ffffffffffffffffffffffffffffffffffffffff"}, "latest"], "id":1}' {"jsonrpc":"2.0","id":1,"result":"0x0000000000000000000000000000000000000000000000000000000000000001"}
