如何解决.net 核心对 http GET 和发送正文的错误请求
我正在尝试发送 http GET 请求,但我收到了 400 BadRequest。 我只需要有人来确认我正确打包了请求。 我认为我的内容不好?
var um = "123456";
var request = new HttpRequestMessage
{
Method = HttpMethod.Get,RequestUri = new Uri($"{_iOptions.Server}{_iOptions.Method.GetData}")
};
request.Content = new ByteArrayContent(Encoding.UTF8.GetBytes("{ \"um\": " + um + " }"));
request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var responseMessage = await _httpClient.SendAsync(request).ConfigureAwait(false);
responseMessage.EnsureSuccessstatusCode();
GetResponse response = await responseMessage.Content.ReadAsAsync<GetResponse>();
if (response.Code == (int)System.Net.HttpStatusCode.OK)
{
response.Success = true;
return response;
}
else
{
response.Success = false;
return response;
};
解决方法
因为数据格式是application/json
,所以必须使用HttpMethod.Post。并且该值应在 (Encoding.UTF8.GetBytes("{ \"um\": \"" + um + "\" }")
中添加双引号。
var client = new HttpClient();
var um = "123456";
var request = new HttpRequestMessage
{
Method = HttpMethod.Post,RequestUri = new Uri("https://localhost:...")
};
request.Content = new ByteArrayContent(Encoding.UTF8.GetBytes("{ \"um\": \"" + um + "\" }"));
request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var responseMessage = await client.SendAsync(request).ConfigureAwait(false);
responseMessage.EnsureSuccessStatusCode();
//...
另外,确保后端被对象接收。
[HttpPost]
public IActionResult get([FromBody]MyModel myModel)
{
return Ok(myModel.um);
}
和模型
public class MyModel
{
public string um { get; set; }
}
