| Bitcoin Core HTTP POST Over Unix Socket Example | ||
| ============================== | ||
|
|
||
| This example shows how to use the rpcclient package to connect to a Bitcoin | ||
| Core RPC server using HTTP POST mode over a Unix Socket with TLS disabled | ||
| and gets the current block count. | ||
|
|
||
| ## Running the Example | ||
|
|
||
| The first step is to use `go get` to download and install the rpcclient package: | ||
|
|
||
| ```bash | ||
| $ go get github.com/btcsuite/btcd/rpcclient | ||
| ``` | ||
|
|
||
| Next, modify the `main.go` source to specify the correct RPC username and | ||
| password for the RPC server: | ||
|
|
||
| ```Go | ||
| User: "yourrpcuser", | ||
| Pass: "yourrpcpass", | ||
| ``` | ||
|
|
||
| As Bitcoin Core supports only HTTP, we'll redirect RPC requests from the | ||
| Unix Socket to Bitcoin Core. For this example, we'll use the `socat` command: | ||
|
|
||
| ``` | ||
| socat -d UNIX-LISTEN:"my-unix-socket-path",fork TCP:"host-address" | ||
| socat -d UNIX-LISTEN:/tmp/test.XXXX,fork TCP:localhost:8332 | ||
| ``` | ||
|
|
||
| Finally, navigate to the example's directory and run it with: | ||
|
|
||
| ```bash | ||
| $ cd $GOPATH/src/github.com/btcsuite/btcd/rpcclient/examples/bitcoincorehttp | ||
| $ go run *.go | ||
| ``` | ||
