C#通过HttpClient访问WebAPI，获取返回结果

HttpClient的使用方法有很多，不再赘述。
1.Web API

	[Route("api/[controller]")]
    [ApiController]
    public class ValuesController : ControllerBase
    {
        // GET api/values
        [HttpGet("requesttest")]
        public IActionResult RequestTest()
        {
            return Ok("返回的信息");
        }
    }

2.Web APP

public class IndexModel : PageModel
{
    private IHttpClientFactory _httpClientFactory;
    public IndexModel(IHttpClientFactory httpClientFactory)//通过依赖注入方式，注意在startup类中注册   services.AddHttpClient();
    {
        _httpClientFactory = httpClientFactory;
    }
    public string Result { get; set; }
    public async Task OnGetAsync()
    {
        var client = _httpClientFactory.CreateClient();
        var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:5100/api/values/requesttest");
        var respond = await client.SendAsync(request).Result.Content.ReadAsStringAsync();//
        Result = respond;//显示
    }
}
