httpclient调用WebAPI

1、创建webapi项目，提供接口方法如下：

/// <summary>

/// 获取租户、位置下的所有传感器

/// </summary>

/// <returns></returns>

[AcceptVerbs("POST")]

[Route("api/Sensors/GetSensors")]

public JsonResponseBase<List<TenSensorDTO>> GetSensors()

{

Logger.Debug("SensorsController---------------GetSensors");

string jsonData = this.Request.Content.ReadAsStringAsync().Result;

Logger.Information(jsonData);

TenSensorSearchDTO search = null;

var response = new JsonResponseBase<List<TenSensorDTO>>();

try

{

search = JsonConvert.DeserializeObject<TenSensorSearchDTO>(jsonData);

response.Json.IsSuccess = true;

}

catch(Exception ex)

{

Logger.Fatal(ex);

response.Json.IsSuccess = false;

response.Json.OperationDesc = "参数错误";

}

if (response.Json.IsSuccess && search != null)

{

response = TenantManageService.GetSensorList(search);

}

return response;

}

2、客户端使用httpclient调用

string url = urlPRe + "Sensors/GetSensors";

//租户ID必须传入，LocationID可以不传入，看调用段需求

var content = new { TenantID = Guid.Parse("5ebf5f81-ac69-418c-b170-9eb255201dd1") ,

LocationID = Guid.Parse("db5a58c0-1d12-4fe9-99bb-4bebe6bcb935") };

var requestJson = JsonConvert.SerializeObject(content);

HttpContent httpContent = new StringContent(requestJson);

httpContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

var httpClient = new HttpClient();

var responseJson = httpClient.PostAsync(url, httpContent)

.Result.Content.ReadAsStringAsync().Result;
