如何使用接受 FromBody 参数的 API GET 方法

Question

如何在 C# 中使用接受一个 FromUri 参数和第二个 FromBody 参数的 Web API 2 GET 命令。我不知道如何在 GET 命令中发送正文，我需要使用 POST 命令吗？但如何呢？下面是我到目前为止编写的代码。谢谢。

API代码

[HttpGet]

[ResponseType(typeof(IEnumerable<Student>))]

public IHttpActionResult Find([FromUri]string searchText,[FromBody]SearchType searchType)

{

    //EF code to get data from DB

    using (handler)

    {

        return Ok(handler.Find(searchText, searchType));

    }

}

Http客户端代码

static void Main(string[] args)

{

     HttpClient client = new HttpClient();

     client.BaseAddress = new Uri("http://localhost:55587/");

     client.DefaultRequestHeaders.Accept.Clear();

     client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));

     string aSearchText ="John";

     SearchType aSearchType = SearchType.Name; //this is enum

     Task<HttpResponseMessage> responseTask = client.GetAsync($"api/Student/{aSearchText}");

     responseTask.Wait();

     ////////////////////

     /// Code missing how to send "aSearchType" as a body in Get Command?

     ////////////////////

     var ListTask = responseTask.Content.ReadAsAsync<IEnumerable<Student>>();

     ListTask.Wait();

     IEnumerable<Student> list = ListTask.Result;

     foreach(Student s in list)

     {

         Console.WriteLine(s.Name);

     }

}

您可以将参数从 body 传递到 HttpGet 操作，但这不符合逻辑。您可以使用 HttpPost 从正文发送数据。[HttpPost][ResponseType(typeof(IEnumerable<Student>))]public IHttpActionResult Find([FromBody]SearchType searchType,[FromUri]string searchText){&nbsp; &nbsp; //EF code to get data from DB&nbsp; &nbsp; using (handler)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; return Ok(handler.Find(searchText, searchType));&nbsp; &nbsp; }}string aSearchText ="John";&nbsp; &nbsp; &nbsp;SearchType aSearchType = SearchType.Name; //this is enum&nbsp; &nbsp; &nbsp;Task<HttpResponseMessage> responseTask = client.PostAsJsonAsync($"api/Student/{aSearchText}",aSearchType );&nbsp; &nbsp; &nbsp;responseTask.Wait();
