我完全是httprepl的新手，不明白为什么会收到该错误

我尝试了来自https://devblogs.microsoft.com/aspnet/httprepl-a-command-line-tool-for-interacting-with-restful-http-services/的推荐

任何运气...

请帮助我 新api项目中的一些代码

                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseAuthorization();

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

        [HttpGet]

            var rng = new Random();
            return Enumerable.Range(1,5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),TemperatureC = rng.Next(-20,55),Summary = Summaries[rng.Next(Summaries.Length)]
            })
            .ToArray();
        }
    }
}

解决方法

我今天在使用新的 .Net Core 5.0 解决方案时遇到了同样的问题。当我尝试从 git bash 窗口运行 httprepl https://localhost:5001 时，我收到了与您相同的消息。当我通过 Windows 命令提示符窗口运行 httprepl https://localhost:5001 时，它运行得很好。

也许您是从包管理器提示运行它的事实是您的问题。
