Webmaster Forum / ColdFusion / Advanced Techniques / September 2007Can I do this in coldfusion?
Hi all. I need to do the following 1. Log into a website 2. click a link 3 download a file by clicking a button (and accepting the file download in the pop up) Can I do this in coldfusion? In theory yes, but it's not easy. Speaking at a high level, you'll need to do the following: 1) CFHTTP POST your login credentials. 2) Analyze response for successful/unsuccessful login 3) If unsuccessful login, abort with error message 4) If successful login, capture cookie/state variables returned 5) If you know what the address of the file to download is going to be ahead of time, use CFHTTP GET (passing along all cookie/state vars explicitely) to retrieve the file and save it to disk on the CF-server **If the address of the file to download is dynamic, you can try using CFHTTP GET to retrieve the raw HTML of the page that displays the "link" in question, and you can then use regular expression searches to locate and discover the address of the file you want to download. I hope this helps. Hmmm. This forum is acting funky this morning. Messages appearing and disappearing. Anyway, to be honest. I am alittle lazy and don't really want to code all this. Do applications exist which can capture the users actions, record them, then repeat them when required. C++ or Visual Basic would be much better langauges for this type of application. I'm sure there are applications doing this already but you might need to do some deep searching, however, instructions on how to do this are really easy to find. Here is one link that explains how to do it... http://http://dn.codegear.com/article/30197 [q][i]Originally posted by: [b][b]SilentBob'secretfusion[/b][/b][/i] Hmmm.

[/q] JMeter (http://jakarta.apache.org/jmeter/ ) can actually do exactly what you're asking for. With Jmeter, you can "record" a user's session clicking around a web site, and you can save it to a "test plan". You can then re-run that "test plan" over and over again. You can also configure it to run multiple "threads" (users) performing those actions at the same time. This tool often comes in handy for performance and load testing, but can be used for a variety of other purposes. Are you talking about building a website where users can login and download files you are hosting with the site? This is trivial and the only part that would require actual CFML code is the login verification. Everything else could technically be straight HTML. Or are you asking how to use ColdFusion to login to another site and download files from the remote site to the CF server. That is the process Grizzly described. No... What I mean is can I create an application in coldfusion that doest the following: 1. Logs into a website (for example www.needreport.com) 2. Provides login credentials upon request of www.needreport.com 3. After login happens, the coldfusion application will click a link imbedded in www.needreport.com. Basically, I need to create an application which acts like a user using a browser. Can this be done in coldfusion, if not, does any know of an application or a language which do this? [i]1. Logs into a website (for example www.needreport.com) 2. Provides login credentials upon request of www.needreport.com[/i] <cfhttp url="http://www.needreport.com/login.cfm" method="post"> <cfhttpparam name="username" type="FormField" value="me_myself"> <cfhttpparam name="password" type="FormField" value="1243"> </cfhttp> [i]3. download a file[/i] <cfhttp method="Get" url="http://www.needreport.com/downloadPage.cfm" throwOnError="Yes" /> We assume the download file is embedded in downloadpage.cfm by means of the combination cfheader/cfcontent. In this way the host server could arrange a login and download session for you. Hmmm... I spoke too quick. When I got down to testing it I found that i could only download text files in this manner. Binaries give encoding problems. Will look into it some other time. Not feeling too well. Back to my last post as promised. My first experiment with downloading binaries using cfhttp in that way led to an encoding problem. However, I have solve it. I simply applied the functions and . <!--- downloadPage.cfm (on first Coldfusion server, e.g. needReport.com) ===================================================================== ---> <cfcontent type="application/msword" file="c:\coldfusion8\wwwroot\forDownload\report.doc"> <!--- getReport.cfm (on a second Coldfusion server) ================================================= ---> <cfhttp getasbinary="yes" url="http://www.needreport.com/downloadPage.cfm" throwOnError="Yes" /> <cffile action="WRITE" file="c:\coldfusion8\wwwroot\report\sept07report.doc" output="#toBinary(toBase64(cfhttp.filecontent))#"> |
