Question

我正在尝试使用Java开发一个简单的在线商店应用程序，我得到谷歌的在线支付。
我刚刚注册了谷歌商家，并且已经拥有我的发行人和密码但我对谷歌提供的示例有一些疑问，以下代码是示例商家请求。

private String getJWT() throws InvalidKeyException, SignatureException {
  JsonToken token = null;
  token = createToken();
  return token.serializeAndSign();
}

private JsonToken createToken() throws InvalidKeyException{
  //Current time and signing algorithm
  Calendar cal = Calendar.getInstance();
  HmacSHA256Signer signer = new HmacSHA256Signer(ISSUER, null, SIGNING_KEY.getBytes());

  //Configure JSON token
  JsonToken token = new JsonToken(signer);
  token.setAudience("Google");
  token.setParam("typ", "google/payments/inapp/item/v1");
  token.setIssuedAt(new Instant(cal.getTimeInMillis()));
  token.setExpiration(new Instant(cal.getTimeInMillis() + 60000L));

  //Configure request object
  JsonObject request = new JsonObject();
  request.addProperty("name", "Piece of Cake");
  request.addProperty("description", "Virtual chocolate cake to fill your virtual tummy");
  request.addProperty("price", "10.50");
  request.addProperty("currencyCode", "USD");
  request.addProperty("sellerData", "user_id:1224245,offer_code:3098576987,affiliate:aksdfbovu9j");

  JsonObject payload = token.getPayloadAsJsonObject();
  payload.add("request", request);

  return token;
}

除了这一行

，一切都很清楚

request.addProperty("sellerData", "user_id:1224245,offer_code:3098576987,affiliate:aksdfbovu9j");

有人会解释我应该如何设置这些？这些是什么？！

Answer 1

终于找到了它：D

它是可选字段，当事务成功发送者回发uri时谷歌会发送相同的数据。

需要帮助来设置谷歌商家请求
