1、在appsettings.json中配置第三方應用服務地址
“OtherServerConfig”: {
“ApplicationServerUrl”: “http://192.168.199.111:8017”, //第三方應用服務地址
}
2、Startup.cs文件中配置
代碼：
services.AddHttpClient("OtherApplicationServer", c =>
{
c.BaseAddress = new Uri(_appConfiguration["OtherServerConfig:ApplicationServerUrl"]);//地址從配置文件appsettings.json裏取
c.Timeout = TimeSpan.FromSeconds(30);//超時間時間設置爲30秒
});
3、客戶端請求封裝接口
參考下圖，
第一步：創建接口類：IOtherHttpClient
代碼如下：
/// <summary>
/// 客戶端請求封裝接口
/// </summary>
public interface IHttpClient
{
/// <summary>
///
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="client"></param>
/// <param name="action"></param>
/// <param name="param"></param>
/// <returns></returns>
public Task<T> GetData<T>(HttpClient client, string action, dynamic param);
/// <summary>
///
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="client"></param>
/// <param name="action"></param>
/// <param name="param"></param>
/// <returns></returns>
public Task<T> PostData<T>(HttpClient client, string action, dynamic param);
/// <summary>
///
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="client"></param>
/// <param name="action"></param>
/// <param name="param"></param>
/// <returns></returns>
public Task<T> PutData<T>(HttpClient client, string action, dynamic param);
}
第二步：創建實現類：OtherHttpClient
代碼如下：
/// <summary>
/// 應用服務類
/// </summary>
public class OtherHttpClient : IOtherHttpClient, ITransientDependency
{
/// <summary>
/// Get請求獲取
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="client"></param>
/// <param name="action"></param>
/// <param name="param"></param>
/// <returns></returns>
public async Task<T> GetData<T>(HttpClient client, string action, dynamic param)
{
try
{
HttpResponseMessage response;
using (HttpContent httpContent = new StringContent(JsonConvert.SerializeObject(param), Encoding.UTF8))
{
httpContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
client.DefaultRequestHeaders.Add("x-token", "M3Q_mQEwmn9l4Ly7fM7DxaMSdlYSSup5lfKLztF");
response = await client.GetAsync(action).ContinueWith(res =>
{
return res;
}).Result;
}
if (response != null && response.IsSuccessStatusCode)
{
return await response.Content.ReadAsAsync<T>();
}
else
{
return default(T);
}
}
catch (Exception ex)
{
throw;
}
finally
{
}
}
/// <summary>
/// Post請求獲
/// </summary>
/// <typeparam name="T">返回值類型</typeparam>
/// <param name="client"></param>
/// <param name="action"></param>
/// <param name="param">參數</param>
/// <returns></returns>
public async Task<T> PostData<T>(HttpClient client, string action, dynamic param)
{
try
{
HttpResponseMessage response;
using (HttpContent httpContent = new StringContent(JsonConvert.SerializeObject(param), Encoding.UTF8))
{
httpContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
client.DefaultRequestHeaders.Add("x-token", "M3Q_mQEwmn9l4Ly7fM7DxaMSdlYSSup5lfKLztF_VP97Urf");
response = await client.PostAsync(action, httpContent).ContinueWith(res =>
{
return res;
}).Result;
}
if (response != null && response.IsSuccessStatusCode)
{
return await response.Content.ReadAsAsync<T>();
}
else
{
return default(T);
}
}
catch (Exception ex)
{
throw;
}
finally
{
}
}
/// <summary>
/// Put請求
/// </summary>
/// <typeparam name="T">返回值類型</typeparam>
/// <param name="client"></param>
/// <param name="action"></param>
/// <param name="param">參數</param>
/// <returns></returns>
public async Task<T> PutData<T>(HttpClient client, string action, dynamic param)
{
try
{
HttpResponseMessage response;
using (HttpContent httpContent = new StringContent(JsonConvert.SerializeObject(param), Encoding.UTF8))
{
httpContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
client.DefaultRequestHeaders.Add("x-token", "M3Q_mQEwmn9l4Ly7fM7DxaMSdlYSSup5lfKLztF_VP97Urf");
response = await client.PutAsync(action, httpContent).ContinueWith(res =>
{
return res;
}).Result;
}
if (response != null && response.IsSuccessStatusCode)
{
return await response.Content.ReadAsAsync<T>();
}
else
{
return default(T);
}
}
catch (Exception ex)
{
throw;
}
finally
{
}
}
文件結構：
4、接口中調用方式如下：
先引入：
private IOtherHttpClient _OtherHttpClient;
private readonly IHttpClientFactory _clientFactory;
HttpClient _applicationClient;
public SupApplyAppService(IRepository<upervision, string> repository,
IHttpClientFactory clientFactory,
IOtherHttpClient OtherAHttpClient
) : base(repository)
{
_repository = repository;
_clientFactory = clientFactory;
_applicationClient = _clientFactory.CreateClient("OtherApplicationServer");
_OtherHttpClient = OtherHttpClient;
}
調用封裝好的方法：
public async Task<bool> CreateInfo(SupervisionWFDto input)
{
Task<bool> isSuccess = Task.FromResult<bool>(false);
try
{
//調用第三方接口
await _OtherHttpClient.PostData<ResultDto<List<WorkOutDto>>>(_applicationClient, $"/jaxrs/work/process/{input.ProcessInput.ProcessGuid}", input.InParam)
.ContinueWith(res =>
{
if (res.Result.type == "success")
{
isSuccess = Task.Factory.StartNew(() =>
{
//新增數據
base.Create(input.Input);
return true;
});
}
}
return res;
});
}
catch (Exception e)
{
throw new UserFriendlyException(e.Message);
}
return isSuccess.Result ? true : false;
}
