在MVC中回传Ajax post中的参数

// 前端Ajax请求
$.ajax({
    url: '/api/data',
    type: 'POST',
    contentType: 'application/json',
    data: JSON.stringify({ name: 'John', age: 30 }),
    success: function(response) {
        console.log(response);
    },
    error: function(xhr, status, error) {
        console.error(error);
    }
});

// 后端Controller
[HttpPost("api/data")]
public IActionResult PostData([FromBody] DataModel model)
{
    if (ModelState.IsValid)
    {
        // 处理数据
        return Json(new { success = true, message = "Data received successfully" });
    }
    else
    {
        return Json(new { success = false, message = "Invalid data" });
    }
}

// 后端设置CORS
public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options =>
    {
        options.AddPolicy("AllowAllOrigins",
            builder =>
            {
                builder.AllowAnyOrigin()
                       .AllowAnyHeader()
                       .AllowAnyMethod();
            });
    });

    services.AddControllers();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseRouting();

    app.UseCors("AllowAllOrigins");

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });
}
