[英]PutAsync doesn't send request to web api, but fiddler works fine
[英]HttpClient PutAsync doesn't send a parameter to api
在控制器上Put如下:
[HttpPut]
[ActionName("putname")]
public JsonResult putname(string name)
{
var response = ...
return Json(response);
}
問題在於通過以下方式消費此API
using (httpClient = new HttpClient())
{
string name = "abc";
string jsonString = JsonConvert.SerializeObject(name);
var requestUrl = new Uri("http:...../controller/putname/");
using (HttpContent httpContent = new StringContent(jsonString))
{
httpContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");
HttpResponseMessage response = httpClient.PutAsync(requestUrl, httpContent).Result;
}
此代碼不會將參數名稱傳遞給控制器。 我甚至嘗試將uri更改為/ putname /“+ name。
這對我有用:
var jsonString = "{\"appid\":1,\"platformid\":1,\"rating\":3}";
var httpContent = new StringContent(jsonString, Encoding.UTF8, "application/json");
var message = await _client.PutAsync(MakeUri("App/Rate"), httpContent);
Assert.AreEqual(HttpStatusCode.NoContent, message.StatusCode);
和我的行動方法:
public void PutRate(AppRating model)
{
if (model == null)
throw new HttpResponseException(HttpStatusCode.BadRequest);
if (ModelState.IsValid)
{
// ..
}
}
和模型
public class AppRating
{
public int AppId { get; set; }
public int PlatformId { get; set; }
public decimal Rating { get; set; }
}

對我而言,它工作正常:
string requestUrl = endpointUri + "/Files/";
var jsonString = JsonConvert.SerializeObject(new { name = "newFile.txt", type = "File" });
HttpContent httpContent = new StringContent(jsonString);
httpContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue ("application/json");
HttpClient hc = new HttpClient();
//add the header with the access token
hc.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
//make the put request
HttpResponseMessage hrm = (await hc.PostAsync(requestUrl, httpContent));
if (hrm.IsSuccessStatusCode)
{
//stuff
}
