Should be "" rather than null.

Only implement [DATA, 20 Bytes - address]
Did not implement: [QUANTITY|TAG - integer block number, or the string "latest", "earliest" or "pending", see the default block parameter]

ex:

params: [
   '0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b',
   '0x2'  // 2
]

For example: when querying to the mongo, if mongo querying spending too much long time, the error should forward to something and print it out.

However, it didn't show up as it should be.

It must reveal the intact information about what it is wrong:
ex: should be： Retrieve receipts failed...(because......)

Because the data in mongoDB has change, e.g. The type of transaction value in BS_Blocks is "[]string"
, however, the original format is []Transaction.

The bug struct in...

type Block struct {
	Author           string `bson:"author"`

}

Because the parameter of getLogs has "latest" which is to get the latest block in the blockchain,
thus the type of blockNumber in the receipt should be the integer in order to easily query the result.

Need to modify the writing rule in bc2 or manually change the type in MongoDB by the script.

In modules/agent/historyUtils/common/parameterCheck
The method:

1. Check40HeximalFormat
2. Check64HeximalFormat
   should return (true or false), err only.

If the result from model.RetrieveReceipts in getTxReceipt.go is empty, then it will occur index out of range".

The response of this two method can only return the hashes of transactions when parameter is "true"
