从HTTP事件流Java中提取数据

Question

I am currently carrying out test automation using a Selenium based Automation framework. I am currently sending in HTTP requests in order to create an API suite.

However the next URL I need to post in is part of a text/event-stream. The data I require to extract is within the eventStream itself.

a["{\"jsonrpc\":\"2.0\",\"id\":1,\"result\":{\"VirgoSessionToken\":\"8C7A0FAA-EA27-473A-BCC3-E568ABDBD403\",\"Localization\":{\"LocaleString\":\"en_UK\",\"LanguageTag\":\"en-UK\",\"DecimalSeparator\":\".\",\"ZeroDigit\":\"0\",\"ThousandsSeparator\":\",\",\"CurrencySymbolLocation\":\"PREFIX\"},\"Balance\":{\"Timestamp\":1493730819967,\"Banks\":{\"CREDIT\":{\"Amount\":83872,\"CurrencyCode\":\"GBP\",\"MinorCurrencyUnits\":2,\"CurrencySymbol\":\"GBP\"},\"WINNINGS\":{\"Amount\":0,\"CurrencyCode\":\"GBP\",\"MinorCurrencyUnits\":2,\"CurrencySymbol\":\"GBP\"}}},\"Preferences\":{\"Global\":{},\"Game\":{}},\"State\":{\"value\":\"{\\\"serverState\\\":{\\\"player\\\":{\\\"uniqueVirgoId\\\":\\\"f85551d0-2f36-11e7-9136-314c3f96f318\\\",\\\"playerBindingState\\\":{\\\"20\\\":0,\\\"40\\\":0,\\\"60\\\":0,\\\"80\\\":0,\\\"100\\\":0,\\\"200\\\":0,\\\"400\\\":0,\\\"600\\\":0,\\\"800\\\":0,\\\"1000\\\":0,\\\"2000\\\":0,\\\"4000\\\":0,\\\"6000\\\":0,\\\"8000\\\":0,\\\"10000\\\":0},\\\"populated\\\":true},\\\"game\\\":{\\\"currencyCode\\\":\\\"\\\"}},\\\"jackpotState\\\":{}}\"},\"ApiPhase\":\"Idle\"}}"]   

I need to extract the Amount value using Java. Apologies if the code formatting isn't great.

Is there a best way to extract Data from EventStreams?

As an example of what my framework does:

String webSocketUrl = insHostedUrl + responseTitle + "/xc_yx4r_" + "/eventsource";
assertTrue(httpCreateRequest("post", webSocketUrl);
assertTrue(httpSendRequest());
response = httpGetResponse();

This posts in the URL that is visible in the requests. However this does not get me to the eventStream data.

You can probably use the google json library and run some code like this.

 JsonObject jsonObject = new JsonParser().parse({\\"Amount\\":0}").getAsJsonObject(); System.out.println(jsonObject.get("Amount").getAsString());
