[英]Xamarin.Forms HTTP Post to Web Service - 404 Error
抱歉,是否已經有人問過這個問題,但是我似乎找不到與我的問題有關的問題。 我有一個使用C#Asp.Net Web API構建的Web服務,這里有以下POST方法:
[HttpPost]
[Route("AddLocation")]
public void PostLocation(Locations model)
{
using (Entities db = new Entities())
{
C_btblFALocation newLocation = new C_btblFALocation()
{
cLocationCode = model.Code,
cLocationDesc = model.Description
};
db.C_btblFALocation.Add(newLocation);
db.SaveChanges();
}
}
在我的Xamarin.Forms項目中,我有Rest Service類:
public async Task SaveLocationAsync(Locations item)
{
var uri = new Uri(string.Format(Constants.LocationSaveRestUrl));
try
{
var json = JsonConvert.SerializeObject(item);
var content = new StringContent(json, Encoding.UTF8, "application/json");
HttpResponseMessage response = null;
response = await client.PostAsync(uri, content);
if (response.IsSuccessStatusCode)
{
Debug.WriteLine(@" Location successfully added.");
}
else
{
Debug.WriteLine(@" Oops, there seems to be a problem.");
}
}
catch (Exception ex)
{
Debug.WriteLine(@" ERROR {0}", ex.Message);
}
}
我的網址是在我的Constants類中設置的:
public static string LocationSaveRestUrl = "http://172.16.124.18/ArceusService/api/Assets/AddLocation/";
問題是我不斷收到404錯誤。 我已經盡力嘗試設置URL,但是沒有運氣。 數據似乎是通過調試傳遞的,但是我不知道POST方法的URL應該如何?
謝謝你的幫助!
您的client
變量如何聲明? 通常,您設置一個BaseAddress
並且在Get/PostAsync
僅設置實際的資源URI。
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://something.com/api/");
var response = await client.GetAsync("resource/7");
}
