asp.net - asp.net mvc core web api相同的模式操作并非一直有效

Question

我的控制器中有两种操作方法。

[Route("users")]
[ApiController]
public class UsersController : ControllerBase
{
    [HttpGet]
    [Route("username/{username}")]
    public async Task<IActionResult> GetUserByUsername(string username)
    {
        var response = await _userService.GetUserByUsername(username);

        return Ok(response);
    }

    [HttpGet]
    [Route("search/{term}")]
    public async Task<IActionResult> Search(string term)
    {
        var response = await _userService.Search(term);

        return Ok(response);
    }
}

这些是相同的模式。但有时我称之为Search行动，它运行GetUserByUsername行动。为什么会出现这种情况？

• http://localhost/users/username/mmyusername => calls GetUserByUsername
• http://localhost/users/search/fra => calls Search
• http://localhost/users/search/français => returns nothing but 200 ,becaues
• http://localhost/users/search?term=fra => calls GetUserByUsername

在您的 Search 端点上使用[FromUri]属性，将方法更新为如下；

    [HttpGet]
    [Route("search")]
    public async Task<IActionResult> Search([FromUri] string term)
    {
        var response = await _userService.Search(term);

        return Ok(response);
    }
