POST抛出HttpRequestMessage不包含Form的定义 [英] POST throws HttpRequestMessage does not contain a definition for Form

问题描述

我正在尝试使用C＃获取POST数据，并且我读过的所有内容都说要使用

I am trying to get POST data in C# and everything I have read says to use

Request.Form["parameterNameHere"]

我正在尝试尝试此操作，但出现错误提示

I am trying that, but I get an error saying

System.Net.Http.HttpRequestMessage不包含Form的定义，也不包含Form的扩展方法。'

System.Net.Http.HttpRequestMessage does not contain a definition for Form and no extension method for Form.'

有问题的方法是

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.HttpRequest;

namespace TextServer.Controllers
{
public class TextController : ApiController
{
    // POST api/<controller>
    public HttpResponseMessage Post([FromBody]string value)
    {
        string val = Request.Form["test"];
        HttpResponseMessage response = new HttpResponseMessage();
        response.Content = new StringContent("Your message to me was: " + value);
        return response;
    }

任何帮助将不胜感激。

推荐答案

您应该在请求正文中传递您的对象，并从正文中检索值：

You should pass your object in the request body and retrieve values from the body:

public HttpResponseMessage Post([FromBody] SomeModel model)
{
    var value = model.SomeValue;
    ...

或者如果您需要的只是字符串：

Or if all you need is the string:

public HttpResponseMessage Post([FromBody] string value)
{
    HttpResponseMessage response = new HttpResponseMessage();
    response.Content = new StringContent("Your message to me was: " + value);
    return response;
}
