Post FromBody始终无效 [英] Post FromBody Always Null

问题描述

我有一个新的API，我正在使用ASP.NET Core构建，我无法将任何数据POST到端点。

I've got a new API that I'm building with ASP.NET Core, and I can't get any data POST'ed to an endpoint.

以下是端点的样子：

[HttpPost]
[Route("StudentResults")]
public async Task<IActionResult> GetStudentResults([FromBody]List<string> userSocs, [FromBody]int collegeId)
{
    var college = await _collegeService.GetCollegeByID(collegeId);
    // var occupations = await _laborMarketService.GetOccupationProgramsBySocsAndCollege(userSocs, college);
    return Ok();
}

这就是我通过Postman发送的有效载荷如下：

And here's what my payload that I'm sending through Postman looks like:

{
    "userSocs": [
            "291123",
            "291171",
            "312021",
            "291071",
            "152031",
            "533011"
        ],
    "collegeId": 1
}

我确保我将邮递员设为POST， Content-Type application / json 。我究竟做错了什么？

I'm making sure that I have postman set as a POST, with Content-Type application/json. What am I doing wrong?

推荐答案

你总是 null 因为你需要封装你的所有帖子只有一个对象内的变量。像这样：

You get always null because you need to encapsulate all your post variables inside only one object. Like this:

public class MyPostModel {
    public List<string> userSocs {get; set;}
    public int collegeId {get; set;}
}

然后

public async Task<IActionResult> GetStudentResults([FromBody] MyPostModel postModel)
