asp.net-core - 使用asp .net core 查询参数路由

Question

我想使用 url 查询参数而不是使用 .net 核心 API 的路径参数。

Controller

[Route("api/[controller]/[action]")]
public class TranslateController : Controller
{
    [HttpGet("{languageCode}")]
    public IActionResult GetAllTranslations(string languageCode)
    {
        return languageCode;
    }
}

startup.cs 仅使用默认设置

public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddMvc()
            .AddJsonOptions(jsonOptions =>
            {
                jsonOptions.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore;
                jsonOptions.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
                jsonOptions.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
            });

    services.AddLogging();
    services.AddSingleton<IConfiguration>(Configuration);

    services.AddSwaggerGen(c =>
    {
        c.SingleApiVersion(new Info
        {
            Version = "v1",
            Title = "Translate API",
            Description = "bla bla bla description",
            TermsOfService = "bla bla bla terms of service"
        });
    });
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    app.UseMvc();

    app.UseSwagger();
    app.UseSwaggerUi();
}

我的招摇请求看起来像这样


我的 postman 请求在这里


我想更改我的 GetAllTranslations 以接受查询参数而不是路径参数，但是当我将 postman 查询更改为

http://localhost:42677/api/Translate/GetAllTranslations?languageCode=en

我会收到错误 404 Not found 所以很明显我的 Controller 路径设置不正确，但我不知道如何做到这一点......有什么想法吗？

我曾尝试删除 [HttpGet("{languageCode}")] 属性，但我一直收到空参数而不是值。

这就是你要找的

public IActionResult GetAllTranslations([FromQuery]string languageCode)
