我使用HttpClient調用ASP .Net Web API併成功調用動作。另外我也可以將自定義對象投入使用。Post標量數據類型使用HttpClient.PostAsJsonAsync
現在我面臨的問題是,無法發佈一樣整數,字符串等標量數據類型...
下面是我的控制器和應用程序代碼調用該調用操作
//測試應用程序
[Test]
public void RemoveCategory()
{
HttpClient client = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage();
HttpResponseMessage response = client.PostAsJsonAsync<string>("http://localhost:49931/api/Supplier/RemoveCategory/", "9").Result;
Console.WriteLine(response.Content.ReadAsStringAsync().Result);
}
//控制器和行動中的Web API
public class SupplierController : ApiController
{
NorthwindEntities context = new NorthwindEntities();
[HttpPost]
public HttpResponseMessage RemoveCategory(string CategoryID)
{
try
{
int CatId= Convert.ToInt32(CategoryID);
var category = context.Categories.Where(c => c.CategoryID == CatId).FirstOrDefault();
if (category != null)
{
context.Categories.DeleteObject(category);
context.SaveChanges();
return Request.CreateResponse(HttpStatusCode.OK, "Delete successfully CategoryID = " + CategoryID);
}
else
{
return Request.CreateResponse(HttpStatusCode.InternalServerError, "Invalid CategoryID");
}
}
catch (Exception _Exception)
{
return Request.CreateResponse(HttpStatusCode.InternalServerError, _Exception.Message);
}
}
發帖時表示「類別」表中Northwind數據庫正常工作,但所有的事情,我無法發表像Integer和String
標量數據當我交的字符串數據類型,我得到以下異常
custome對象{「消息」:「沒有HTTP資源發現該請求URI‘http://localhost:49931/api/Supplier/RemoveCategory/’相匹配。」,「MessageDetail」:「無動作被在控制器‘供應商’與請求匹配找到」}
Can an an你指導我嗎?
