设置 POST Web API 方法？

Question

我需要设置 Web API 方法来接受从我的 Android 和 iOS 客户端应用程序发送的 POST 参数。这就是我现在拥有的：

[HttpPost]
[Route("api/postcomment")]
public IHttpActionResult PostComment([FromBody]string comment, [FromBody]string email, [FromBody]string actid)
{
       string status = CommentClass.PostNewComment(comment, email, actid);
       return Ok(status);
}

但是这行不通，因为我认为该方法不能同时获取多个 [FromBody] 参数？如何正确设置此方法，使其从请求正文中接受 3 个 POST 参数？

Answer 1

您可以使用模型。 DefaultModelBinder 会将 表单 中的那些值绑定到您的模型。

public class CommentViewModel
{
    public string Comment { get; set; }
    public string Email { get; set; }
    public string Actid { get; set; }
}

public IHttpActionResult PostComment([FromBody]CommentViewModel model)
{
    string status = ...;
    return Ok(status);
}

你可以这样做 -

1. Create one custom class and add three properties for your three input parameters.
2. Change the PostComment method to accept only one parameters of that class.
3. While calling this WebAPI, create one object of this class, assign values to the properties, serialize it to JSON or XML and POST it.
4. The WebAPI will automatically de-serialize your Request Body and pass it to your method.
