关于合约事件监听的问题

[likhita-8091]

我是copy代码库中的example下的event示例代码，但是也是监听不到，

是不是和我的bcos版本有关系，bcos是2.8的版本，go-sdk是dev版本，

你可以在go-sdk执行下面的命令

bash .ci/integration_test.sh

会产生一个hello.go的文件，里面有main函数，可以参考，如下

func main() {
    configs, err := conf.ParseConfigFile("config.toml")
    if err != nil {
        log.Fatalf("ParseConfigFile failed, err: %v", err)
    }
    client, err := client.Dial(&configs[0])
    if err != nil {
        fmt.Printf("Dial Client failed, err:%v", err)
        return
    }
    address, tx, instance, err := DeployHello(client.GetTransactOpts(), client)
    if err != nil {
        fmt.Printf("Deploy failed, err:%v", err)
        return
    }
    fmt.Println("contract address: ", address.Hex()) // the address should be saved
    fmt.Println("transaction hash: ", tx.Hash().Hex())

    hello := &HelloSession{Contract: instance, CallOpts: *client.GetCallOpts(), TransactOpts: *client.GetTransactOpts()}
    ret, err := hello.Get()
    if err != nil {
        fmt.Printf("hello.Get() failed: %v", err)
        return
    }
    done := make(chan bool)
    err = hello.WatchAllSetValue(nil, func(ret int, logs []types.Log) {
        fmt.Printf("WatchAllSetValue receive statud: %d, logs: %v\n", ret, logs)
        setValue, err := hello.ParseSetValue(logs[0])
        if err != nil {
            fmt.Printf("hello.WatchAllSetValue() failed: %v", err)
            panic("WatchAllSetValue hello.WatchAllSetValue() failed")
        }
        fmt.Printf("receive setValue: %+v\n", *setValue)
        done <- true
    })
    if err != nil {
        fmt.Printf("hello.WatchAllSetValue() failed: %v", err)
        return
    }
    fmt.Printf("Get: %s\n", ret)
    _, _, err = hello.Set("fisco")
    if err != nil {
        fmt.Printf("hello.Set failed: %v", err)
        return
    }
    ret, err = hello.Get()
    if err != nil {
        fmt.Printf("hello.Get() failed: %v", err)
        return
    }
    fmt.Printf("Get: %s\n", ret)
    <-done
    from := common.HexToAddress("0x83309d045a19c44Dc3722D15A6AbD472f95866aC")
    hello.WatchSetValue(nil, func(ret int, logs []types.Log) {
        fmt.Printf("WatchSetValue receive statud: %d, logs: %+v\n", ret, logs)
        setValue, err := hello.ParseSetValue(logs[0])
        if err != nil {
            fmt.Printf("hello.WatchSetValue() failed: %v", err)
            panic("hello.WatchSetValue() failed")
        }
        fmt.Printf("WatchSetValue receive setValue: %+v\n", *setValue)
        done <- true
    }, from, from)
    <-done
}
