c# - 如何从同一项目中的另一个 Api Controller 调用 Api Controller

Question

我有一个对象“ApplicantDetail”，其中包含 ApplicantController 中的对象列表，我想将发布请求发送到 Personaldetails Api 以保存到数据库并获得响应

ApplicantController 上的 API

    // POST: api/ApplicantDetail
    [HttpPost]
    [Route("~/api/ApplicantDetail")]
    public IActionResult Post([FromBody] Personaldetail ApplicantDetail)
    {

        Personaldetail personaldetail = new Personaldetail
        {
            Name = ApplicantDetail.Name,
            Cnic = ApplicantDetail.Cnic,
            Phone = ApplicantDetail.Phone
        };

        List<Address> addresses = new List<Address>();
        List<Employee> employees = new List<Employee>();
        List<Bank> banks = new List<Bank>();

        addresses.AddRange(ApplicantDetail.Address);
        employees.AddRange(ApplicantDetail.Employee);
        banks.AddRange(ApplicantDetail.Bank);

        var response = *//How to Call Personaldetail Post APi of PersonaldetailController Controller From Here and Get 
          response back//*

        return null;
    }

个人细节 Controller 上的API

    // POST: api/Personaldetails
    [HttpPost]
    public async Task<IActionResult> PostPersonaldetail([FromBody] Personaldetail personaldetail)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        _context.Personaldetail.Add(personaldetail);
        await _context.SaveChangesAsync();

        return CreatedAtAction("GetPersonaldetail", new { id = personaldetail.ApplicantId }, personaldetail);
    }

Answer 1

您应该创建一个服务类来表示个人详细信息 API。在此类中，您将注入(inject) HttpClient，然后使用强类型客户端设置 IHttpClientFactory:

public class PersonalDetailsService
{
    private readonly HttpClient _client;

    public PersonalDetailsService(HttpClient client)
    {
        _client = client;
    }

    // methods here to interact with API via `_client`
}

然后，在 ConfigureServices 中:

services.AddHttpClient<PersonalDetailsService>(c =>
{
    c.BaseAddress = new Uri(Configuration["PersonalDetailsAPIUrl"]);
    // configure anything else you need to on the `HttpClient`
});

最后，在您的 Controller 中，注入(inject) PersonalDetailsS​​ervice:

[ApiController]
[Route("api/ApplicantDetail")]
public class ApplicantController
{
    private readonly PersonalDetailsService _personalDetailsService;

    public ApplicantController(PersonalDetailsService personalDetailsService)
    {
        _personalDetailsService = personalDetailsService;
    }

    [HttpPost("")]
    public async Task<IActionResult> Post([FromBody] Personaldetail ApplicantDetail)
    {
        ...

        var response = await _personalDetailsService.SomeMethodAsync(someParam);

        return null;
    }
}
