I'm newbie in Java and wanna ask you question. Let's imagine the situation. I generate account for testing purposes using API and in response I get line e.g. such as:

{
 "accountId": "42515896"
}

How could I write method that will take this "42515896" from the response and insert it into some int variable that I declared before?

public class failedAuthorization {
    // created reference variable for WebDriver
    WebDriver driver;

    @BeforeMethod
    public void setup() {

        System.setProperty("webdriver.chrome.driver","C:\\Users\\imagineName.imagineSurname\\chromedriver\\chromedriver.exe");
// initializing driver variable using Chrome Driver
        driver=new ChromeDriver();
        driver.manage().deleteAllCookies();
// launching google.com on the browser
        driver.get("https://login.live.com/");
// maximized the browser window
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);

    }

e.g. I have some API request that generate me account and in response I get data that I will need further to login. How to use generated data?

CodePudding user response：

You probably want to use some external library to parse response to Java object, for example Jackson

Simple solution (using JsonNode):

String jsonString = "{'accountId': '42515896'}";
ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = mapper.readTree(jsonString);
actualObj.get("accountId").textValue(); //returns 42515896

CodePudding user response：

You can use json path:

    public static void main(String[] args) {
        String myJson = "{\"accountId\": \"42515896\"}";
        String accountId = JsonPath.read(myJson, "$.accountId");
        System.out.println(accountId);
    }
