我正在将非常简单的json数据发布到 Core 2.0 API.
I'm posting very simple json data to a Core 2.0 API.
为什么我有这样的方法?
Why is it when I have a method like this:
public async Task<IActionResult> GetNewToken([FromBody]string id)然后id为null,但是如果我将其封装在模型中:
Then id is null, but if I encapsulate that in a model:
public class RandomViewModel { public string id { get; set; } } public async Task<IActionResult> GetNewToken([FromBody]RandomViewModel model)那我的ID是否正确填充?
Then my id is populated correctly?
推荐答案如果您的路线内容类型为 application/json ,因为mvc等待模型将json主体绑定到模型,而不是原始类型.
You can not get primitive types from your body directly like ([FromBody] string id) if your route content type is application/json because mvc waits model to bind json body to model not primitive types.
有一些从请求正文中获取基本类型的选项

将内容类型更改为纯文本/

使用 StreamReader 获取原始令牌字符串.

使用MVC InputFormatter
StreamReader 示例:
[HttpPost] public async Task<IActionResult> GetNewToken() { using (StreamReader reader = new StreamReader(Request.Body, Encoding.UTF8)) { var token = await reader.ReadToEndAsync(); // returns raw data which is sent in body } // your code here }InputFormatter 示例: weblog.west-wind/posts/2017/Sep/14/Accepting-Raw-Request-Body-Content-in-ASPNET-Core-API-控制器
