 [HttpPost("admin/api/staff/login")]
        ITask<ApiResult<LoggedModel>> Login([JsonContent] StaffLoginApiModel model);

注入

services.AddHttpApi<IStaffApi>()
                .ConfigureHttpApi(o =>
                {
                    o.HttpHost = new Uri("http://localhost:53518/");
                });

使用

var result = await StaffApi.Login(model); Console.WriteLine(result);

接口返回消息内容 { "content": null, "message": "用户不存在", "success": false, "serverTime": "2020-11-24 16:21:39" }

项目是blazor wasm 项目。能正常的请求接口并正常返回数据。接口正常。但是无法给result 赋值，result的值是null值。其他get接口正常，但是post接口就无法得到值。

你在接口关联[LoggingFilter]特性，然后在浏览器的console看看请求日志，或者把浏览器上的请求与响应贴出来以分析

是因为数据序列化导致到问题 o.JsonDeserializeOptions.NumberHandling = JsonNumberHandling.AllowReadingFromString; .net 5设置后解决问题。
