我想使用从第一个 API 调用收到的 ID 作为我的第二个 API（不同服务）在 RestSharp..Specflow 场景中的候选条目

Question

In RestAPI specflow in VS2022: I made one API call and received ID in response content. Now I want to use that ID (which is received from first API Call ) as a candidate entry for my second API ( Different service) In RestSharp..Specflow scenario like

Given : a API is healthy 
    When  I create user throught the API (x)
            | Field     | Value             |
            | Firstname | PersonName        |
            | Lastname  | SurName           |   
    And  I make a get call for another service with ID generated from API(x)
    Then  the API should returns a "success" response

Above scenario is description only

I did use in the stepdefination till received USER ID but then....?

This is a good use case for context injection , which allows you to share data between steps.

Generally, it follows this format:

1. Create a class that holds the data your test is interested in. This is use case specific and should match the needs of your testing framework.

2. Register an instance of this class with the dependency injection framework in SpecFlow.

3. Declare this class as a constructor parameter in your step definitions, and assign it to a field or property.

4. Use it in a step definition.

For your use case, this would be a good starting point.

First, create a class to hold test data using types and property names that make sense for the application you are testing. As an example:

public class ApiTestData
{
    public Guid UserId { get; set; }
}

This class can be simple. Don't over complicate this. It will hold data you want to share between steps.

Next, register it with the DI container:

[Binding]
public class Hooks
{
    private readonly IObjectContainer container;

    public Hooks(IObjectContainer container)
    {
        this.container = container;
    }

    [BeforeScenario]
    public void BeforeScenario()
    {
        var testData = new ApiTestData();

        container.RegisterInstanceAs(testData);
    }
}

After that, you can add ApiTestsDate testData to the constructor parameters of any step definition class to get an instance of this object. To create the user:

[Binding]
public class UserApiSteps
{
    private readonly ApiTestData testData;

    public ApiSteps(ApiTestData testData)
    {
        this.testData = testData;
    }

    [When(@"I create user throught the API \(x\)")]
    public void CreateApiUser()
    {
        var response = // call the web API, get the response

        testData.UserId = response.UserId; // change this to suite your needs
    }
}

And finally to use the Id in another step:

[Binding]
public class OtherApiSteps
{
    private readonly ApiTestData testData;

    public OtherApiSteps(ApiTestData testData)
    {
        this.testData = testData;
    }

    [When(@"I make a get call for another service with ID generated from API\(x\)")]
    public void MakeOtherCall()
    {
        var userId = testData.UserId;

        // make API call with `userId`
    }
}
