修改Abp中Auto API Controllers中 默认生成的 Put、Delete请求

在做公家的项目，有个奇葩的规定，Http请求 不能用Put和Delete。

怎么在使用Abp，自动生成的Api，全局修改原有规则，将修改、删除都改成Post呢？

只需要，在Host项目的XXXModule类中，重写的PreConfigureServices方法，加上如下代码即可。

HttpMethodHelper.ConventionalPrefixes = new Dictionary<string, string[]>
{
    { "GET", ["GetList", "GetAll", "Get"] },
    { "POST", ["Create", "Add", "Insert", "Post", "Put", "Update", "Delete", "Remove", "Patch"] }
};

运行发现，恭喜您报错了

Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException: The request matched multiple endpoints. Matches: 

Acme.BookStore.Books.BookAppService.DeleteAsync (Acme.BookStore.Application)
Acme.BookStore.Books.BookAppService.UpdateAsync (Acme.BookStore.Application)

解决方案，可重新实现IConventionalRouteBuilder并替换原有实现context.Services.Replace(ServiceDescriptor.Transient<IConventionalRouteBuilder, CustomConventionalRouteBuilder>());。

public class CustomConventionalRouteBuilder : ConventionalRouteBuilder
{
    public CustomConventionalRouteBuilder(IOptions<AbpConventionalControllerOptions> options) : base(options)
    {

    }

    public override string Build(
        string rootPath,
        string controllerName,
        ActionModel action,
        string httpMethod,
        ConventionalControllerSetting? configuration)
    {
        var url = base.Build(rootPath, controllerName, action, httpMethod, configuration);
        if (action.ActionName == "Delete" && httpMethod == "POST")
            return $"{url}/Del";
        return url;
    }
}

如果想指定方法，则。只需要项目中添加Microsoft.AspNetCore.Mvc.Core的NuGet包，可以使用ASP.NET Core的标准属性（[HttpPost]、[HttpGet]、[HttpPut]……）
