# Running the Payment Protocol Demo
|
||||
This is an example of Bitcore's Payment Protocol implementation, including a
|
||||
mocked server (`server.js`) and client (`customer.js`).
|
||||
|
||||
1. Start the server: `node server.js`
|
||||
2. Start the customer: `node customer.js`
|
||||
## Node
|
||||
|
||||
At this point, you should see an acknowledgement from your local server:
|
||||
The node payment protocol demonstration will run automatically via:
|
||||
|
||||
``` bash
|
||||
$ node examples/PayPro
|
||||
```
|
||||
|
||||
You will see the server and customer logs output in the terminal.
|
||||
|
||||
## Browser
|
||||
|
||||
To run our payment protocol demonstration in the browser, you may run:
|
||||
|
||||
``` bash
|
||||
$ node examples/PayPro/server.js -b -p 8080
|
||||
```
|
||||
|
||||
This will start the payment protocol demonstration server in browser mode,
|
||||
which serves outputs in the payment protocol request (don't worry, it doesn't
|
||||
ask for *too* many testnet coins).
|
||||
|
||||
Once the server is started, you can visit it in your browser:
|
||||
|
||||
``` bash
|
||||
$ chromium https://localhost:8080/
|
||||
```
|
||||
|
||||
You will see a simple checkout page to buy some imaginary products. Once you
|
||||
press checkout, you will see all the server and client logs in the browser as
|
||||
well as the terminal.
|
||||
|
||||
If you're connected to enough peers, your transaction will be broadcast
|
||||
throughout the bitcoin testnet network and hopefully ACKed by your peers.
|
||||
|
||||
## Logs
|
||||
|
||||
Your logs may ultimately look something like this:
|
||||
|
||||
```
|
||||
Customer: Our payment was acknowledged!
|
||||
Customer: Message from Merchant: Thank you for your payment!
|
||||
Customer: Payment sent successfully.
|
||||
```
|
||||
|
||||
## Changing the server address contained in outputs
|
||||
|
||||
If you want to alter the address or public key the testnet coins get sent to by
|
||||
the payment server, you can pass in the `--pubkey` or `--address` options.
|
||||
`address` has to be a testnet address, whereas `pubkey` is a hex encoded public
|
||||
key. The `--privkey` option is also available in the standard bitcoind privkey
|
||||
format.
|
||||
|
||||
## Other Options
|
||||
|
||||
If you you're not connected to enough peers to broadcast your transaction (by
|
||||
default, this example only connects to the core seed peers), you can enable
|
||||
peer discovery in bitcore by passing the `--discovery` (`-d`) argument onto the
|
||||
server command line.
|
||||
|
||||
If you don't want to actually broadcast your transaction and want to keep your
|
||||
testnet coins, you can pass `--no-tx` on the server command line.
|
||||
|
||||
If you don't want the tests to run automatically and simply host the payment
|
||||
server, simply pass `--browser` (`-b`) as mentioned above.
