问题 BufferingHelper.EnableRewind(); Above is an extension method for HttpRequest object in ASP.NET Core 2.2. It is no more there in ASP.NET Core 3.0 (atleast with this name). I want to know it's alternate in ASP.NET Core 3.0. I am not sure if HttpRequestRewindExtensions.EnableBuffering(); is the alternate. 回答1: The alternate is HttpRequestRewindExtensions.EnableBuffering() , indeed. You can see here that internally it just calls EnableRewind() . 来源： https://stackoverflow.com/questions/57407472

问题 I want to run a "background job" in my ASP.NET application (periodically, as separate thread). And I need host name (DNS name or IP) to do my tasks. The problem is that the HttpContext.Current may be not available here (it's NULL ). Is there any way to get a host name in not using HttpContext.Current.Request.Url.Host . 回答1: When the host name is available in HttpContext.Request.Url.Host , it is a result of the host name being part of the request sent by the client.

问题 Note before reading This is not a duplicate of what-are-differences-between-xmlhttprequest-and-httprequest And for info, I tried this lib without success, because it copies the structure of the XMLHttpRequest but doesn't actually act like it.

问题 I call the same controller many times from _Layout.cshtml view. So in this controller, how can I discover at runtime if it's still same page that is rendering or if a brand new page request is being made? In asp.net you can use ispostback to figure this out. How can you tell if a brand new request is being made for a page in MVC3? Thanks 回答1: There's no such think on MVC. You've actions that can handle POSTs, GETs or both. You can filter what each action can handle using [HttpPost] and

问题 Asynchronous http requests using Netty and Scala actors Hey hope someone can give me a hand with this. I am trying to use the Scala Actors and Netty.io libraries to get make asynchronous http requests.

问题 I'm building my own WebhookClient for dialog flow. My code is the following (using Azure Functions, similar to Firebase Functions): module.exports = async function(context, req) { const agent = new WebhookClient({ request: context.req, response: context.res }); function welcome(agent) { agent.add(`Welcome to my agent!!`); } let intentMap = new Map(); intentMap.set("Look up person", welcome); agent.handleRequest(intentMap); } I tested the query and the response payload looks like this: {

问题 GET : $.get(..) POST : $.post().. What about PUT/DELETE ? 回答1: You could use the ajax method: $.ajax({ url: '/script.cgi', type: 'DELETE', success: function(result) { // Do something with the result } }); 回答2: $.ajax will work. $.ajax({ url: 'script.php', type: 'PUT', success: function(response) { //... } }); 回答3: We can extend jQuery to make shortcuts for PUT and DELETE: jQuery.each( [ "put", "delete" ], function( i, method ) { jQuery[ method ] = function( url, data, callback, type ) { if (
