asp.net-mvc - 未找到 WebAPI

Question

遗憾的是，我无法使用 WebAPI 获得最基本的东西

$.ajax({
    url: "https://192.168.1.100/Api/Authentication/LogIn",
    type: "POST",
    contentType: "application/json",
    data: "{ 'username': 'admin', 'password': 'MyPass' }",
    error: function (r, s, e) { alert(e); },
    success: function (d, s, r) { alert(s); }
});

我得到“未找到”

API Controller 定义

public class AuthenticationController : ApiController
{
    [HttpPost]
    public bool LogIn(string username, string password)
    {
        return true;
    }
}

如果我删除 HttpPost 并用 HttpGet 替换它，然后这样做

$.ajax({
    url: "https://192.168.1.100/Api/Authentication/LogIn?username=admin&password=MyPass",
    type: "GET",
    error: function (r, s, e) { alert(e); },
    success: function (d, s, r) { alert(s); }
});

效果很好。

WebAPI 出了什么问题？

这篇文章应该有助于回答您的一些问题。

I believe the thinking here is that, especially in a RESTful API, you’ll want to bind data to the single resource that a particular method deals with. So, pushing data into several loose parameters isn’t the sort of usage that Web API caters to.

在处理发布数据时，您可以像这样告诉您的操作方法正确绑定(bind)其参数:

public class LoginDto {
    public string Username { get; set; }
    public string Password { get; set; }
}

[HttpPost]
public bool LogIn(LoginDto login) {
    // authenticate, etc
    return true;
}
