问题 My server moved to a new location and I need to redirect requests to the new location. If I use HttpServletResponse.sendRedirect(new_server_location), I am losing all the POST data coming along with the original request. Is it possible to redirect to the new location without losing any of the POST data? The POST data can contain sensitive information like passwords. So making a GET request on the new server location is NOT an option. Thanks in advance for the responses. 回答1: The sendRedirect(

问题 I've built a DataSnap REST server using Delphi XE2 and I've added a server method for uploading files via TStream : function TServerMethods.updateUploadFile(sFilename: string; UploadStream: TStream): string; I want to be able to call this from a number of different clients (Android, iOS etc) and I've been testing the method using various REST clients such as Postman (Chrome plugin). However so far I cannot get it to accept the content for the HTTP POST body. Whenever I send the POST command I

问题 I am new to NodeJS and inside of AWS Lambda I am trying to make a POST request that calls an external API with a JSON object, creates a document with the response and then reads the contents of the file. Coming from a Ruby background, I'm thinking the problem stems from my unfamiliarity with asynchronous programming, but I've tried using callbacks and readfileSync just to debug with no luck. Any help would be appreciated. var querystring = require('querystring'); var https = require('https');

问题 We've hit a problem with some forms in the admin portion of our web app. There are a handful of forms that contain a large number of fields (it can range anywhere from one input field to the hundreds). We've found that as these forms grow, there is a point where the server will throw 500 errors when a form is posted. After running a test, I was able to find that the server can handle forms with 100 fields in them; once 101 or more fields are used, we get the errors. We run Coldfusion, and we

问题 Is there a way to determine if an <asp:UpdatePanel /> has performed an Ajax postback similar to how we can use... if(!Page.IsPostBack) { ...snip } ... to determine if a postback from a button submit is taking place. I'm trying to detect Ajax requests from jQuery, but it's picking up UpdatePanel requests as well which I want to exclude eg... if (Request.IsAjaxRequest() && !Page.IsUpdatePanelPostback) { // Deal with jQuery Ajax } 回答1: I don't know if this will work any better than your solution

问题 I'm using Java to query a Solr server for results that have IDs within a set of known IDs that I am interested in. The best way I could think to get just these results that I am interested in was to create a long query string that looks something like this: q=(item_id:XXX33-3333 OR item_id:YYY42-3445 OR item_id:JFDE-3838) I generate this String, queryString , before making my request, and there are over 1500 such ids included in the request I would eventually like to make. I am using an HTTP

问题 I'm trying to implement Firebase Topic Messaging in an Android application, and I'm attempting to build a HTTP post request, and I'm receiving a response code of 400.
