Csharp 多个参数的最小API删除

发布于12月01日

看起来MapDelete是希望传递一个ID，但我的情况是，我需要传递一对ID.我以为传递一个JSON对象内容会起作用，但事实并非如此.让POST充当DELETE可以起作用，但它必须有不同的路径. 下面是我的代码，结果是the request matched multiple endpoints.

 app.MapPost("/movies/achievements", async (CreateMovieAchievementCommand cmd, ISender sender) =>
 {
     var id = await sender.Send(cmd);
     return TypedResults.Created("/movies/achievements", id);
 });
 app.MapPost("/movies/achievements", async (RemoveMovieAchievementCommand cmd, ISender sender) =>
 {
     await sender.Send(cmd);
     return TypedResults.Ok();
 });

我想改变最后一个要么MapDelete或一些如何使2个职位足够不同，它不会导致歧义(希望保持网址相同，如果可能的话)

RemoveMovieAchievementCommand等于AchievementId和MovieId

推荐答案

您已经定义了两个相同的终结点.将RemoveMovieAchievementCommand改为删除，这在REST API范例中更加惯用(请注意，需要显式FromBodyAttribute):

app.MapDelete("/movies/achievements",
    async ([FromBody] RemoveMovieAchievementCommand cmd, ISender sender) =>
    {
        await sender.Send(cmd);
        return TypedResults.Ok();
    });

此外，通常您只需要id即可删除，因此您可以执行如下操作:

app.MapDelete("/movies/achievements/{id}", async (idType id, ISender sender) =>
{
    await sender.Send(new RemoveMovieAchievementCommand {Id = id});
    return TypedResults.Ok();
});

RemoveMovieAchievementCommand等于AchievementId和MovieId

我认为，更多的RESTFull方法将转移到请求路径:

app.MapDelete("/movies/{movieId}/achievements/{achievementId}",
    async (MovieIdType movieId, AchievementIdType achievementId, ISender sender) =>
    {
        await sender.Send(new RemoveMovieAchievementCommand
        {
            AchievementId = achievementId,
            MovieId = movieId
        });
        return TypedResults.Ok();
    });
