The contract platform provides a native evidence deposit transaction API to facilitate development of evidence deposit scenarios.
Evidence deposit transaction
depositData
This API is called synchronously for evidence deposit transactions.
Function prototype
public DepositDataResponse depositData(DepositDataRequest request)Request parameter
Parameter | Required | Type | Description |
request | true | DepositDataRequest | The evidence deposit transaction request. |
Response field
Response field | Field type | Description |
response | DepositDataResponse | The evidence deposit transaction response. |
Example
DepositDataRequest request = new DepositDataRequest(senderId, receiverId, depositData, amount);
// Refer to the error message description document to check the returned data.
DepositDataResponse response = sdk.getAccountService().depositData(request);asyncDepositData
This API is called asynchronously for evidence deposit transactions.
Function prototype
public int asyncDepositData(DepositDataRequest request, IAsyncCallback callback)Request parameter
Parameter | Required | Type | Description |
request | true | DepositDataRequest | The evidence deposit request. |
callback | true | IAsyncCallback | The callback function. |
Response field
Response field | Field type | Description |
result | int | The return value. |
Example
DepositDataRequest request = new DepositDataRequest(senderId, receiverId, depositData, amount);
int result = sdk.getAccountService().asyncDepositData(request, new IAsyncCallback() {
@Override
public void onResponse(int errorCode, Response response) {
// Refer to the error message description document to check the returned data.
System.out.println("async deposit data, errorCode:" + errorCode + ", response: " + response.getErrorCode());
}
});Evidence deposit transaction request parameters
The following table describes parameters of DepositDataRequest.
Parameter | Type | Description |
senderId | Identity | The identity of the transaction initiator. |
receiverId | Identity | The identity of the target account. |
amount | BigInteger | The transfer amount, the default value is 0, does not support modification (that is, does not support transfer transactions) |
depositData | byte[] | The data to be stored. You can customize the data content, serialize it for an evidence deposit, read the data, and then deserialize it. |
Note: The size of data for an evidence deposit transaction has an upper limit, which is a configuration option for the contract chain and is 1 MB by default. You can set the value based on the actual contract chain configuration.
Evidence deposit transaction response parameters
The following table describes parameters of DepositDataResponse.
Parameter | Type | Description |
transactionReceipt | TransactionReceipt | The transaction receipt. |
blockNumber | BigInteger | The block number. |
