golang链码不能按预期工作,手动将数据存储在分类帐上,但在尝试通过函数调用存储数据时不能这样做

我试图在超账本结构上存储资金转移记录。我已经在go lang中编写了链代码。当我在initLedger函数中添加数据时,它工作得很好。但当我从createTransfer(我将提供两个代码)等其他函数调用它时,它会显示成功的事务,但当我检索链数据时,它不会出现在其中。

传输结构

type Transfer struct {
    TransferID  string `json:"transferID"`
    FromAccount string `json:"fromAccount"`
    ToAccount   string `json:"toAcount"`
    Amount      string `json:"amount"`
}

这个函数将数据写入分类账:当我在in it ledger方法中直接调用它时,它工作正常

func writeTransferToLedger(APIStub shim.ChaincodeStubInterface, transfers []Transfer) sc.Response {

    for i := 0; i < len(transfers); i++ {
        key := transfers[i].TransferID
        chkBytes, _ := APIStub.GetState(key)
        if chkBytes == nil {
            asBytes, _ := json.Marshal(transfers[i])
            err := APIStub.PutState(transfers[i].TransferID, asBytes)
            if err != nil {
                return shim.Error(err.Error())
            }
        } else {
            msg := "Transfer already exist" + key + " Failure---------------"
            return shim.Error(msg)
        }
    }
    return shim.Success([]byte("Write to Ledger"))
}

在createTransfer函数中调用writeToTransferLedger方法:

func (s *SmartContract) createTransfer(APIStub shim.ChaincodeStubInterface, args []string) sc.Response {
    if len(args) != 4 {
        return shim.Error("Incorrect Number of arguments for transfer func, Expecting 4")
    }
    transfers := []Transfer{Transfer{TransferID: args[0], FromAccount: args[1], ToAccount: args[2], Amount: args[3]}}

    writeTransferToLedger(APIStub, transfers)
    return shim.Success([]byte("stored:" + args[0] + args[1] + args[2] + args[3]))
}

当我从nodesdk代码调用createTransfer时,它会成功执行,但当我从链代码检索数据时,不会返回任何东西。

我希望它与createTransfer函数一起工作,因为它与writeTransferToLedger一起工作。

在initLedger方法中,我用给定的数据创建了transfer struct,并调用writeTransferToLedger函数代码,如下所示:

transfer := []Transfer{
        {TransferID: "1233", FromAccount: "US_John_Doe_123", ToAccount: "UK_Alice_456", Amount: "200"},
        {TransferID: "231", FromAccount: "JPY_Alice_456", ToAccount: "UK_John_Doe", Amount: "3000"},
    }
    writeTransferToLedger(APIstub, transfer)
