本文介绍了在ASP.Net Core中发布json时,MVC模型为null的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
所有相关代码:
//JSON data
var dataType = 'application/json; charset=utf-8';
var data = {
FirstName: 'Andrew',
LastName: 'Lock',
Age: 31
}
console.log('Submitting form...');
$.ajax({
type: 'POST',
url: '/Diary/Save',
dataType: 'json',
contentType: dataType,
data: data,
success: function (result) {
console.log('Data received: ');
console.log(result);
}
});
[HttpPost]
public IActionResult Save([FromBody] Person person)
{
return Json(person);
}
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
}
Save方法中的"person"始终为null.这应该可以工作...感觉好像是设置问题吗?我是否需要在此处进行更改:
"person" in the Save method is always null. This should work...it feels perhaps like a settings issue? Do I need to make changes here:
services.AddMvc(options =>
{
});
推荐答案
您需要对发送到服务器的数据进行字符串化,以将其转换为JSON,因为这是您指示的内容类型标头:
You need to stringify the data that you are sending to the server to convert it to JSON because that's the content type header you indicated:
data: JSON.stringify(data)
