Delphi TIdHTTP POST does not encode plus sign

由 孤者浪人 提交于 2019-12-11 03:18:21
问题 I have a TIdHTTP component on a form, and I am sending an http POST request to a cloud-based server. Everything works brilliantly, except for 1 field: a text string with a plus sign, e.g. 'hello world+dog', is getting saved as 'hello world dog'. Researching this problem, I realise that a '+' in a URL is regarded as a space, so one has to encode it. This is where I'm stumped; it looks like the rest of the POST request is encoded by the TIdHTTP component, except for the '+'. Looking at the

Slow responses to TIdHTTP POSTs

问题 I am investigating a problem with a legacy executable, written in Delphi 5, utilising Indy 9. Components in use: TIdHTTP, TIdConnectionIntercept & TIdSSLIOHandlerSocket. The problem the app is presently experiencing is slow responses to TIdHTTP POSTs. I found the following two links: Delphi: Why does IdHTTP.ConnectTimeout make requests slower? Delphi TIdHTTP POST is very slow vs GET Based on the links, I have tried the suggestions of: (i) setting ConnectTimeout to zero and (ii) setting the

Delphi: Setting connection timeout for TIdHttpServer

问题 Using TIdHTTPServer (Indy 10.6), i want set a connection timeout for close slow or inactive client (client are common browser) and close all zombie connection after 60 seconds of inactivity. I have found Socket.ReadTimeout in TIdContext.Connection. Is this the right way? TIdHTTPServer already perform this (it seem have infinite timeout)? WebServer := TIdHTTPServer.Create(nil); WebServer.SessionState := false; WebServer.KeepAlive := false; WebServer.OnCommandGet := CustomOnCommandGet;

Delphi: TIdHTTP vs TNetHTTPClient

由 ℡╲_俬逩灬. 提交于 2019-12-06 05:42:13
I'm writing a download manager in Delphi with some custom features like resumable downloads and downloading through proxies. I'm studing different component solutions: Indy and NetHTTP, both seem very close. TNetHTTPClient seem to be an interface of winhttp.dll . TIdHTTP seem to be an interface of wininet.dll (but i'm not sure). TIdHTTP seems like a very old component (maybe very stable/tested) and has tons of documentation online. TNetHTTPClient seems to be a very recent component, and doesn't have good documentation online. I'm a bit undecided... which one to choose? The point is: what is

Delphi: Why does IdHTTP.ConnectTimeout make requests slower?

由 爱⌒轻易说出口 提交于 2019-12-04 21:12:07
问题 I discovered that when setting the ConnectTimeoout property for a TIdHTTP component, it makes the requests (GET and POST) become about 120ms slower? Why is this, and can I avoid/bypass this somehow? Env: D2010 with shipped Indy components, all updates installed for D2010. OS is WinXP (32bit) SP3 with most patches... My timing routine is: Procedure DoGet; Var Freq,T1,T2 : Int64; Cli : TIdHTTP; S : String; begin QueryPerformanceFrequency(Freq); Try QueryPerformanceCounter(T1); Cli := TIdHTTP

Delphi XE: idHttp & Request.Range, a bug?

由 时光毁灭记忆、已成空白 提交于 2019-12-04 15:08:30
I have Delphi XE. I try to set Request.Range of idHttp but I cannot do this. Delphi doesn't allow me to do this neither at design time nor at run time. E.g. I set '6000-' in a design time -> a property gets empty all time. I do (in a thread): Downloader.Request.Range:=(IntToStr(DFileStream.Position) + '-'); synchronize(procedure begin showmessage(Downloader.Request.Range) end); showmessage(Downloader.Request.Range) shows me nothing (an empty string). I checked a request in HTTPAnalyzer -> my program doesn't send a range. A checked this behavior in Delphi 2010 - all is normal . I set a range in
