rpc: change /tx hash format and update docs #3330
Description
Tendermint version (use tendermint version or git rev-parse --verify HEAD if installed from source):
name = "github.com/tendermint/tendermint"
version = "0.30.0"
Environment:
- OS (e.g. from /etc/os-release): MacOS High Sierra
- Install tools: local go app
What happened:
This line of code should return ResultTx message.
However, it is not working. I am not too sure if I am using it incorrectly or this is a bug.
> tx, err := client.Tx([]byte("2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF"), true)
https://github.com/tendermint/tendermint/blob/master/rpc/core/tx.go#L29
I connected to gaia-12k testnet full node by using websocket like below and successfully received return ResultStatus message from client.Status(). However, Tx() method doesn't seem to work.
How to reproduce it (as minimally and precisely as possible):
I added tendermint v0.30.0 and cosmos-sdk v0.32.0 in my go app.
// txHash: f87370f68c82d9ac7201248eca48cec5f16ffec99c461c1b2961341a2fe9c1c8
func main() {
rpcClient := client.NewHTTP("http://52.78.163.36:26657", "/websocket")
status, err := rpcClient.Status()
if err != nil {
fmt.Println(err)
}
fmt.Println(status.SyncInfo.LatestBlockHeight)
tx, err := rpcClient.Tx([]byte("f87370f68c82d9ac7201248eca48cec5f16ffec99c461c1b2961341a2fe9c1c8"), false)
if err != nil {
fmt.Println(err)
}
fmt.Println(tx.Height)
}
