使用ASP .NET Core的查询参数路由

Question

我想使用url查询参数代替使用.net核心API的path参数。

控制者

[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

我的邮递员要求在这里

我想将GetAllTranslations更改为接受查询参数而不是路径参数，但是当我将邮递员查询更改为

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

我将收到错误404 Not Found，因此显然我的控制器路径设置不正确，但是我无法找到解决方法...有任何想法吗？

我试过删除[HttpGet（“ {languageCode}”））属性，但是我一直在获取null参数而不是值。

这就是你要找的

public IActionResult GetAllTranslations([FromQuery]string languageCode)
