    ASP.NET Core中的Action的返回值类型

    IActionResult HttpOk() { return Ok(); } public async Task AsyncCall() { await Task.Delay(1000); return Content 如果null做为Action的返回值,最后框架会转换为204的http status code。 ? 204表示No Content 。 做为restful api,204的语义在这里会有问题,这里比较适合的status code是404 NOT FOUND 。

    揭秘简单请求与复杂请求

    ,Accept,Authorization); res.header(cache-control, no-cache); res.header(content-type, applicationjson OPTIONS一次为POST,而我们代码中并没有处理对OPTIONS请求的响应处理,所以上面服务端代码是不合理的,综合考虑,OPTIONS请求并会对实际http请求差生影响,所以我们统一的对OPTIONS请求返回204 ,Accept,Authorization); res.header(cache-control, no-cache); res.header(content-type, applicationjson res.header(ETag, ); header头信息设置结束后,结束程序往下执行,返回 if(req.method.toLocaleLowerCase() === options){ res.status(204 ); return res.json({}); 直接返回空数据,结束此次请求 }else{ next(); }});我们在中间件中判断请求方式,如果请求方式为OPTIONS返回状态码204,并返回空信息
